I've been doing fiberglass my whole adult life, I've been doing it for about 34 years. I've been a pattern maker, that was before we got a CNC machine so I've learned to build the patterns by hand. I started off as a mole maker so I've got tons of tooling experience. Then against my better judgment into production lol. I can take a print in pile of materials and end up with a part that fits. So I know what I'm talking about when I say that you, sir are a Glass man. You do all the little things right the things that most people don't bother with. The things like radiusing your wood so that the laminate lays down nicely, priming thirsty wood so you don't end up with dry glass and have a great bond, fraying the mat so that you have a more consistent overlap with more aesthetically pleasing results. Not a lot of glass men left but you sir are one of the good ones. I tip my fiberglass hat to you
Wow, Thank You so Much for the kind words! Sounds like You have a Ton of experience in the Fiberglass world, so what you said really carries some weight. I literally grew up in our family's boat shop, and learned from my Father who was a professional Boatbuilder, and repairman. In a small town like I grew up in, if you don't do quality work you don't stay in business very long, so my father's standard for our work was always very high. I have noticed the same thing as You, not a lot of quality work being shown for folks to learn from out there! Glad the channel is helping people! Much appreciation for taking the time to watch and comment!
I am surprised that you could contain acetone in a plastic bottle
Man I couldn't have said it any better.
You not only hit the nail on the head, You counter sank it and filled it in.
Your channel is growing because of you! You’re an excellent teacher.
You could teach us all anything you’re good at. Fishing, wiring a boat, raising kids… what ever.
Thanks for the content.
Wow, thanks so much! I really appreciate that!
I'm landlocked. I've never had the slightest inclination to build a boat. Why did I just watch an hour of boat repair? Damn dude, you're a great teacher! I probably won't build a boat any time soon, but this was awesome!
Haha,That's hilarious! What a great comment, thanks so much for watching!
A good deal of this information can be used in auto body repair, repairs around the house such as your bathtub if its made of fiberglass, or if you had to waterproof something made of wood, etc.
My grandfather built a 14' boat from cypress plywood and wait a year for the wood. That was in the fifties. I am 62 now and wish you had your channel when my dad and I inherited it in 1974! Thank you for so many memories and instruction!
Very cool, I also grew up around wood skiffs as a boy. My grandfather was a commercial fisherman, and aways had flatbottom skiffs and we had a small floundering skiff made from marine ply over cypress frames and a 18 hp Evinrude. I have some great childhood memories from those boats! Thanks for sharing and for watching!
Takes years to get to this guys level trust me. You can tell how good he is all the way through the video. I especially liked the bit where he made the relief cut in the glass and put it in the bin rather than tossing it down on the floor as I’ve seen people do in UK workshops. Keeping clean with fibreglass is a key element and this guy has mastered it.
Thanks so much! Yes, I find that keeping your work area neat and clean, as well as proper planning before you even start the job make all the difference. I truly appreciate you taking the time to watch and comment on the videos!
i noticed an unspoken bit of knowledge in one of his hard top plug viedos...as hes reaching long over the part...he uses the clean hand to pull back his shirt by pinching the back to stay clean. never looks to see if it clears, just knows it does. he probably should have added that tip in. ive seen new guys get lathered in glass not knowing how to handle and work with it. most of the professional laminators i know instinctively always keep one hand behind they're back, maybe holding a tip brush or something but it stays back and clean and kinda balances the body when reaching out in front of yourself for hours a day.
these videos are strangely addictive. but in all honesty, these should be watched by all new boat building employees. i had a similar idea yesterday that a series with real trade entering knowledge makes sense. i wasn't thinking boats at the time, more like plumbing, electric, etc.. but one should exist for every job. to aide the transition into a real family supporting career.
if a new hire at boston whaler with zero knowledge watched a dozen of your videos, that person would be leaps and bounds ahead of a person that did not.
Wow, thanks! I really appreciate your comment!
This is the best fibreglass boat building channel ever thanks from Australia
Agreed! Best I've ever seen too!
Wow, thanks! That is much appreciated!
If you’re thinking of future content ideas I’m sure we’d all love a breakdown of where you buy bulk materials, rough costs, brands you like, etc. I know you’ve mentioned these things ad hoc, but would appreciate a focused video on it. I imagine you have non-professional viewers (like me) that may want to take on a project but don’t know where to start materials-wise (other then big box stores) and are we talking $1k in supplies or $10k? Thank you!
Great suggestion, thanks so much!
I think the camera operator should be applauded. They follow the action well and zoom in and out appropriately without instruction. Makes it easy for the narrator to do his presentation. Lots of learning that I needed in this video as I prepare to replace my transom and replace the decks in my 23' cuddy cabin outboard.
Thank you! I will be sure to tell him, I am sure he will appreciate it!
I appreciate that the videos as long as you need to instruct all the procedures
Thanks for your thoughts, they are much appreciated!
Love the paint tray tip . Work at a fiberglass pole company and we are bringing back mold making and it is a learning experience .
Glad to help! I hope that our hardtop mold building series is helpful for you all. I appreciate you watching and commenting!
Your content is much appreciated. Clear demonstrations with vast experience and no waffle! Great channel. I've made several boat seat pedestals so far, and may need to up my game when I purchase a new boat shortly.
Subscribed. Kepp up the great content.
I am in the aircraft composite manufacturing industry and use mainly prepreg materials. I am in awe of your skillset and excellent tutorials. I have been doing it since 1995 so I have been at it for awhile. I have seen some of the best and I would say that you are in that category as well. Great channel! Your instruction is spot on and you give very helpful advise. I am going to refer some of the younger technicians on my crew to your channel to help them better their own workmanship.
Wow, thanks so much! I have always had a lot of respect for those that work in the aircraft industry, and your comment means a lot! I appreciate you watching and welcome to the channel!
Can you do a video or the different resins if you haven’t already? You talk about Epoxy, Polyester, Vinyl ester resins but what’s the difference and when to use each? Enjoying your videos!
Great suggestion! We have just such a video in the works. Hope to have it out soon!
Great again! Love it. Super glad I discovered your show. I trust everything you say. I can’t say that for any other show I watch on RUclips.
Wow, thank you! I appreciate you watching and commenting!
Excellent video. I only have a small amount of hands on experience, but I am a certified instructor in several other arenas. I think you are a great teacher and you definitely know your craft, which is evident in your smoothly flowing delivery.
Wow, thank you so much! I appreciate your comment.
Wish you worked at grady-white back in the day. 89, 252gt sailfish. Bracket twins, beautiful boat. When they rigged it, no holes were sealed. Plastic thru-hulls, transom scuppers were under water with the fuel at half tank, and lighter 2 strokes. What a shame, a pocket battle wagon, poorly fitted because some bone head manager needed a bigger bonus. All you got to do is build it right one time, everytime.
It is a shame when you see shortcuts taken just to save a little money on a otherwise awesome boat! With time, money and knowledge, all those problems could be fixed. That's what we are trying to do with the channel, maybe help folks get some of these boats back in good working condition. I hope the videos are a help! We have a lot more planned for the channel, so stay tuned!
Thank you so much Captain for this Demo series. I’m building a three battery , battery box. One house , two trolling 24v. For my 17’ Trophy this is a great video!!
You are very welcome, glad it was helpful!
Awesome video as always. Keep up the good work! I’d love to see a transom repair/replacement.
I'd be interested in this as well. A lot of us getting these older boats where the wood was improperly sealed, especially in the transom.
Thanks so much! I will try to get a transom replacement or something similar for you guys soon.
as the filler is setting up you can shave it with putty knife, before its fully hardened you can tool it to reduce sanding
Thanks for your thoughts, I appreciate you watching!
Fish bump family looking forward to a video of a old school fir plywood floor tying into existing fiberglass hull tabing as well as pour foam techniques I know that asking a lot that may require brother Mark witch requires a lot of mixing and rolling material thank again for your time!!!
I will try to do something along those lines when I get a chance to, but in the meantime, we have videos here on the channel that cover those basic methods. When we put the Coosa decks in on our 29 the process is very similar to the way you would work with plywood. When we installed the fuel tank in the 29, we poured urethane foam all the way around and under it. Then the prep work on the how-to fiberglass over plywood video would apply to the final fiberglass and the recent gelcoat vids for finishing out your project. If you have some time to look back in the channel, especially in the 29-build series, I think you will learn a lot, and maybe answer some of your questions. I hope this helps, and thanks for watching!
Thanks captain Joe, I watch your video from Sweden. I work with buildings and this is useful information for me too... lot of places i have with PVC pipes comming out from plywood that need to be water tight and those places need to be long lasting. In buildings there are lot of ways to make those places water tight but its very good to see long lasting solutions. Thanks for informative, nice, good work 👍
Welcome to the channel! We very much appreciate our viewers from overseas! Sweden looks like a beautiful country; I would love to visit it someday. Glad you are enjoying the videos!
Repetition is a great learning aid.
I agree, thanks for watching!
I’m glad I found these videos I just bought a 1976 Thunder craft boat and it needs some flooring fixed it’s plywood and fiberglass and I can do the plywood but was worried about the fiberglass work of getting it right and wanted to build a rod locker in it but with your videos I believe I can do it now we’re is best place to get the stuff I need
Glad the videos were helpful! We have links below the videos description of many of the products we use, that also helps support the channel. Thanks so much!
Top Notch... as usual ! This was perfect and exactly what I needed to know. I'm using your lessons to make some live wells. I've always wanted to but was hesitant until now. Thanks again.. and thanks for keeping it free of distracting ads.
No reply is necessary . 😊
Love it!
Thank you so much!
Loving the channel and the effort you guys put into the videos, as always invaluable information. Thank you Captain Joe and team, I hope the channel keeps growing 🇦🇺
Wow, thanks so much for the kind words! With everyone's support and encouragement we can do so much with the channel. If it keeps growing, you guys will be seeing more, and better content for sure!
Great video. I’d like to see something on exterior screw hole removal and seal
Thanks, I appreciate the suggestion!
Back in the '60s I took a guided tour of the Glastron boat company in Austin, Tx. The employees were working day in and day out doing polyester fiberglass layups in female molds without gloves or masks. I often wondered what their life expectancy was.
It doesn't seem to bother some people, others can't be anywhere near it. I have grown up around the stuff. When we are not doing videos , we always wear a mask, gloves, tyvek suit etc. Best to be safe!
I don't presently own a boat...but for some reason felt compelled to watch this to the end. It's always fascinating to watch an expert ply (no pun intended) his craft.
Haha, awesome! Thanks for watching!
Thank you so much for sharing all these valuable tips!
Glad it was helpful! Thanks for commenting!
Great video!
Much appreciated!
I have to admit I enjoy your video's. I feel better about my methods after watching several of you vids.
I take a lot of time covering details, or many say over building, after watching you I may not be over building as much as I thought.
More like on Par.
And again I gave up on being timely and efficient.
It takes as long as it takes to get it a certain way or end point.
Maybe with more time things will flow better, But I don't even consider how long I spend on details and point of finish.
I understand and have said from first few months.
I could not afford to buy or purchase a boat built the way I am doing things. The labor would triple the cost of the vessel if factory built this way.
Man I like the ball bearing on a stick., I will build one., "George gotta have one those"
I enjoy the long very detailed video's.
But that Ball tool is the biggest eyeopener so far.
I think the poly over epoxy topic.
Here is my humble opinion.
As long as my build is taking,. The cure time or gassing off over the summer and by the time I get around to it and the tedious surface prep.
I want to think I will be ok... Now I would not use this method in a structural application,. Ever ! (Cosmetic Only)
But guys doing a quick turn around I think you are spot on it may or may not end with the best results.
My thought is these products can take months to fully cure and in that process the things like amine blush that most of us do kinda understand and know how to deal with, Now. But like this topic I was clueless til I encountered it.
I think in addition to being chemically non-compatible,. we have other gassing going on and in the wrong order (poly over epoxy)is like getting oil and water to mix. It is not optimal at best.
Enough folks in the know like yourself have seen 1st. hand that those 2 only play well together epoxy over poly. in that sequence. or Order.
So many, like myself was oblivious to this little detail when I 1st. started this journey.
Thank you covering this.
Glad you are enjoying they videos! I have always said I would rather have a overbuilt boat than a underbuilt boat! A lot of boats are not built with the time and attention to detail that is needed to make them last a lifetime. I appreciate you watching and sharing your thoughts!
love your work
Thanks so much, I appreciate you watching and commenting!
Brilliant, sharing so much knowlege in an entertaining way. No shortcuts and sharing the entire process. Thankyou
Glad you enjoyed it! Thanks for watching!
Awesome content! Thank you for sharing your knowledge!
Thanks, I appreciate you watching!
Great video, very helpful
Glad to help, thanks for the comment!
Superb work. I think if I show this video to my 4 years old daughter she would be able to follow your instructions.
Just amazing.
I hope your channel will grow fast 😍😍
Haha, that's awesome! The kind words are much appreciated!
You guys are the best. Your videos are beyond great. You take time to teach and explain in detail. You do not rush or cut out important steps. And there's no distractions like music etc. Nobody would be able to get all this knowledge anywhere, and for free. Thank you .
Thanks so much! I am glad you are enjoying the channel!
Another excellent video. Well done and thank you. 👍
Glad you enjoyed it! Thanks for the nice comment!
Tłumaczone zawsze poprawnie ze zrozumieniem ,ogromna dawka wiedzy .Pozdrawiam
Thanks, glad you are enjoying the videos!
This is an awesome level of detail! Love the tutorial and tips and tricks. Transferable skill to SO many things. Usually I watch RUclips at 1.5X speed. Not this! Rewatching more of your videos and on a bigger than phone screen soon too. Thank you so much!
Wow, thanks so much! We really appreciate you watching and commenting!
great video!
Glad you enjoyed it!
I absolutely love your channel. You are an amazing teacher and instructor. This is a channel I would pay to watch. Definitely Patreon worthy content!!!
Wow, thank you! What a nice comment, that means a lot to me!
thanks learned a lot from you
Glad to help, best of luck with your project!
You are fantastic to watch, really helping me restore my 1963 French sail boat ❤
Wow, thanks so much! Best of luck with your 1963 restoration!
Thanks for your reply on the other video that I watched!! Nice to see that you are maintaining the channel. I am very interested in this video as I feel that this is where most wood fails!! I really want to learn more about how to do this the absolute best way!! Love that I discovered this channel!!!!
⭐️⭐️⭐️⭐️⭐️👍

Thank you so much! We are getting there and truly appreciate everyone's support and encouragement!
Thanks so much. I am about to start a project and this information will really help.
Glad it was helpful! Best of luck with your project!
Great videos, getting ready for some fiberglass projects on my sailboat. Going to use Marine plywood so this was very helpful.
Glad to help! Thanks for watching!
Another great video! You really put a lot of effort into your videos and Im sure everyone appreciates them, Thanks
Glad you like them! Thanks for the comment.
Your videos are very informative and cover a lot of points that are not thought of by many people. Thank you
Glad you like them! Thanks for taking the time to comment.
Thank you so much for these how-to videos. They are some of the very best I've ever seen on ANY subject. Having a master craftsman as an instructor is confidence inspiring. Keep up the great work!
Wow, you are very welcome! Glad you are enjoying the videos so much!
I have now watched about a half dozen of your videos. I have been doing glass work on and off for about 40 years. I like the long videos, and pick up a lot of little tips. One being thinning old bondo with polyester resin. I will be watching more videos and sharing your channel with my fellow boater/do there own repair work friends.
Thanks, glad you are enjoying the videos!
I am a new to boat building and fiberglass. Enjoy learning from your videos.
Welcome aboard! I appreciate you watching
Thank you very much for all of your instructional videos, I really enjoy them and have been taught so much. I’m curious as to what the lamination/lay-up schedule for the hull on the new boat was. Bottom vs side. Thanks again.
Glad you are enjoying the videos! The hull side are 2 layers of 1 Oz csm for the skin coat, then 6 layers of alternating 1708 and 1808. The hull bottom is 2 layers of 1 oz csm skin coat, then 10 layers of alternating 1708 and 1808 biaxial, this includes the layers used for stringer glass. Thanks for watching!
Thank you for your time
You are very welcome! Thanks for taking your time to watch and comment!
You are correct!
A/C exterior fur plywood works the best for fiberglassing. You can fill the voids on the C side with your polyester fairing putty and a light sanding to have a smooth service. Like you said you should always prime with resin to avoid a dry lay up. 😊
Thank you! I agree with you on the process! Lots of people just don't take the time to seal and install it properly. Not saying that marine fir is better than modern composites, but there is definitely still a place for it on many projects. I appreciate you taking the time to watch and comment!
@@FishBumpTV i’m working on a 1986 Champion bassboat. I’m adding a hinged deck and small half-inch plywood bases for the seats. I cut out a raised lip where the seats sat. I can actually still get the original seats. The problem is the aluminum hinges just don’t hold up over time. After a few years, you’re not sitting at 90° anymore. My question is, do you think I could just seal the half inch plywood with resin only? I am also not concerned about the looks it’s function only. I don’t need any strength from fiber, so I thought the resin alone would work for those.
@@ps7462 If you just wanted to seal with resin, I would consider using epoxy resin as it is considered to be better at waterproofing in thin applications. Hope this helps and thanks for watching
@@FishBumpTVThanks!!
@@ps7462 You are welcome!
Muchas Gracias!!! Saludos desde Argentina
You are very welcome! Thanks for watching all the way from Argentina 🇦🇷
Hi from Denmark👋.
Thank you for these great videos💪. A request from me regarding what to show could be how to build a hatch with marine plywood and fiberglass. Just like those on your new boat but with plywood and fiberglass. I would guess it's a bit more tricky due to the sealing of the plywood.
Keep up the great work👍
Glad you are enjoying the videos! First comment from Denmark, thanks so much for watching! Yes, you are correct, the process would be very similar to building with Coosa board. I will try to get some content on plywood hatches out for you guys. I appreciate the suggestion.
Great video. I'm new to this channel. This channel will be one of my favourite channel. Thanks for sharing. God bless you
Thanks and welcome!
I'd buy one of your boats. I've been building a DIY punt designed by a naval architect and have access to his knowledge through private forums. Every thing your doing here is what we are being taught. It's a good demonstration and very similar proceedure for installing plastic bungs. It's a labour intensive job, it just needs time....
Love the vids, the comms and the vids aren't too long
Wow, thanks! Glad you are enjoying the videos
Thanks again for the info, Wow "Tiger hair" is 100 bucks a can now, whew price sure go crazy
Yes, everything is expensive! Thanks for watching
Great video!!! A quick tip we use that may be helpful for someone. For big pieces of glass instead of tearing and maybe tearing away too much material around the edges to help the glass blend in when wetted out. Lay the straight cut edge down and put something long with a sharp corner under it. Take a soft bristle brush and lightly rake at the edge. It'll get rid of that cut edge and give you more of a feathered edge. What about a video demonstrating cabosil, qcells, microballons , etc as a filler? Or your thoughts on it vs the pro strand?
Thanks so much, I appreciate the tip! I will try to work on a resin additives and fillers video for you guys.
Thanks for the 411 Captain Joe !!!
You are very welcome! Thanks for watching
I am not even into boats but this was an exceptionally excellent detailed video. The fiberglassing might come in handy for something I’d like to build. Superb video Joe. Thank you!
Wow, thanks! Understanding how to work with fiberglass can open up all kinds of options for cool projects, best of luck with yours!
@@FishBumpTV forgot to mention your shop looks so inviting, like if i had a friend with the same shop as you, id come over and watch him work or help out for fun. Thanks. I subscribed. Corvette guys can take hints from your channel.
@@YoungHeartedSoulThanks! Yes, I am lucky to have a shop like our for sure!
Man, that was informative ! I've been toying with the idea of building a new dash console for my 17' aluminum bass boat. Any tips on a fiberglass over plywood dash ?
Haha, thanks! Plywood or Coosa board consoles are a popular thing build or add to your boat. I don't have just one video on that topic, but starting with our how to fiberglass over plywood video then the next 2 or 3 vids after that one should give you a pretty good idea of the process. You might also enjoy our boat building series of our custom 29 ft charter boat. There are over 20 videos in that series, with lots of custom fiberglass and gelcoat work. I hope this helps and thanks for watching!
Top tip from me. Wear TWO latex gloves on each hand. When the top glove gets loaded up with strands simply remove and you have a clean pair on already. Any second saved by not reaching for the glove box is precious seconds especially when you are working in warmer temperatures.
Great tip! Much thanks!
I do this when mechanicing too, it avoids the problem of trying to get a new glove on a wet sweaty hand, and oftentimes small holes and tears only go through the outer layer, if you can notice in time to change outer glove then it keeps the job rolling
I'm a surgical tech and we do this a lot also
Good video ! Great putty hack and in the future if you could explain the difference between a waxed and un waxed resin thanks love what you do.
Thanks, I appreciate the suggestion!
These videos are fantastic. Keep up the good work! I dont know how you deal with the polyester smell so well. I did it for two years while in prototyping and cant do it anymore without a vapor mask.
Glad you are enjoying the videos! We have surprisingly good airflow through the shop, which really helps. We will be doing some work with epoxy soon, the smell is not nearly as strong, but should still always wear good ppe.
Hey jo !
Quick question on the 29 buskens . How much did it end up weighing in at ? Just curious to know the weights as it runs very well with those motors and very surprised how well it runs off one motor ! Well done and keep the vids coming . Learning a lot .
We estimate dry weight, which would be no fuel, water, Batts, or motors to be in the range of 4500 to 5000 pounds. I am really happy with her performance overall, the 150s are plenty of power in my opinion. Thanks for watching and commenting!
I was beginning to think you were going to make a boat out of Campbell's Pork and Beans 😂 Seriously though, professional tips are priceless.
Haha, yep! I was trying to think of a good illustration for sealing the wood and eliminating water absorption. It was the best I could come up with! Thanks for watching!
日本で見ています。とても参考になりました。ありがとうございました。続きも楽しみにしています。
Amazing! Thanks for watching from Japan 🇯🇵! Glad the videos are helpful
Here is a tip to help keep the hairs from the brush out of your work. were the hair meets the metal band around the brush put a little super glue to hold the hairs in place.
Might work on the outside of the brush but not the core so barely worth doing when you can bash the brush into your palm to loosen fibres. A pro will see fibres that shed into the job and lift them as he sees them.
Thanks for the tip, I appreciate you watching and commenting!
Thanks for the tip! I appreciate you watching and commenting!
@@GRPLiningServices that's why i use original super glue that is super thin and runs through the bristles to bind almost all bristles together.
we use those small brushes as well we cal

So if I wanted to add plywood instead of coosa inside my center console to thicken it up to mount electronics to. Would it be better to fully ecapsulate the plywood with glass first then epoxy it in then mold it in, or seal it just with resign, epoxy it in and glass over it to mold it into the inside of the console? I would rather do coosa, but Marine grade plywood is 75% cheaper and readily available here at Home Depot in the East coast of Florida. I would really like this to last a long time without moisture issues. I do plan on doing gel coat once it's molded in. Thank you for all your knowledge you are sharing with us!!!
Awesome again! I like your short intro montage. Have you ever worked with total boat structural repair putty?
Stay True To Thyself, When you get big tell those "sponsors" to kick rocks
Thanks, glad you liked it! No, I haven't used the structural repair putty. I like the 3m vinyl Ester high strength filler for heavy duty applications. I appreciate you watching
Matt glass is held together with a soluble binder (glue), and Polyester resin has Mono Syrene in it, a solvent that dissolves the binder so it wets out the Matt Fiberglass. Epoxy doesn't have any Mono Styrene in it so it cant dissolve the binder in the Matt Gass and is therefore not compatible. Epoxy uses woven cloth that needs no binder, the weave holds it together.
Thanks for the comment and for watching!
The Glass Man- Properly done.
I appreciate that! Thanks for watching
Great answered some f the question I had on my pool build , can someone link me to part 2 - love to know how to seal screw holes?

Can you explain how you made your plastic false ceiling… and how it benefits in certain areas..
Great channel!!
We use the plastic tent to help keep water from dripping on our fiberglass rolls. Our old shop needs a new roof soon, just trying to get a little more life out of it. The estimate for repair was major! Thanks for watching!
Giday from AUS! just came across your channel been binge watching your diy stuff loving it. I’m redoing floor on my boat that was rotten from seats being changed and screws letting water into the plywood, I’m guessing. Should I predrill and fill the holes with resin. Or how should I go about it
Thanks for watching all the way from Australia 🇦🇺!Rotten floors are are a very common problem for sure. I like 3m 4200 for sealing most fasteners in our boats. You certainly could predrilled and seal with resin also, but I would still seal it with 4200. I hope this helps and thanks for watching!
How do you compare pro strand to mixing your own with resin and filler? Pros and cons? Thank you for all the great information love your videos!
You certainly could make or mix your own. I might do a video or touch on that soon. I have had good success with prostrand in this kind of application, and like the convenience and consistency of the product.There are other very good products out there that are similar, 3m makes some vinyl Ester fillers that are very good, but cost 3 times as much. Hope this helps, thanks for watching!
Great video series, thanks. I'm rebuilding the keel stem inside the hull of my boat and replacing the winch tow hook on the bow. Should I drill oversized holes through the timber keel stem and fill with glass before drilling the correct sized holes (8mm or 5/16") for the tow bolt?
Thanks, glad you are enjoying the videos! It is something we do on our boats. Just remember, it only has to be slightly oversized. Then use a very small brush to work some resin into the exposed wood. Be sure to let the resin fully cure before adding a good marine sealant and reinstalling the fastener. Hope this helps, I appreciate you watching!
I’d like to see yall start a boat from the ground up !!!!
That could happen! Thanks for the suggestion!
As someone who knows absolutely nothing about what you do but is very int6in learning, where would I start? I owned 2 boats, a cruiser and a Yamaha.
I've taught myself using youtube how to repair everything mechanically using youtube. Please guide me if you can. Thank you so so much. I just subscribed yesterday. You strike me as the king of your field.
Wow, glad you are enjoying the videos! Thanks so much for watching and commenting
Hello great vidéo very instructive I'm redoing the transom of my Boston Whaler V20 outrage 1979 is there a rule for drain in splash well does it have to be in brass tube or we can install PVC tube like you do in a stringer
Thanks! I think I would go with the brass tubes for a splash well drain. They make a simple tool for installing them, I am pretty sure I show how to install in one of our 29 boat build videos. Hope this helps, and thanks for watching!
Another awesome, informative and helpful video Captain Joe! I really appreciate the time you take explaining things and also answering questions and comments. You're a stand up dude who's is quite the professional.
I've been trying to get through your other videos when I can and have been learning a ton.
Maybe you've covered it somewhere else but I'm curious about your take on mounting accessories to the boat.
For example, I need to install a bilge pump and float switch.
Any advice on that or perhaps you might want to shoot a video covering ways to do it right??
I don't really want to screw it into the bottom of the bilge for fear of creating a point of water intrusion. But if I did is there a safe way to do it so water won't leak past the screw holes?
I've thought about bedding the screws or even glassing a mounting board to then mount the bilge pump and float switch to???
I've also wondered if there was just a simple way to use some kind of adhesive to hold it in place in a typical dirty bilge?
Sorry for the long comment. Thanks again for being so helpful.
Looking forward to watching part two and all the rest of your content.
Thanks so much, I appreciate you taking the time to watch! You are on the right track with your thinking. Look for multiple solutions, then pick the best one for you application. I mounted 2 1500 gal per hr bilge pumps with stainless screws to a piece of 1/2 inch thick polymer in our 29. It sits nicely in the center of the bilge, no grinding or glassing, and is relatively easy to remove or work around if needed. There should be some footage of that in our boatbuilding series in the rigging and hardware phase. Of course every boat is different, but keeping it simple is oftentimes the best way to go. Hope this helps, and best of luck with your project!
Awesome! I'll definitely check that out.
I love your videos very thorough and helpful.
I am wondering how strong the fiber glass is with the plywood.
For instance my kids and i would like to build a john boat to fish with and i am struggling on how thick the marine grade plywood i would have to use.
The reason is i am trying to make it as light as possible thinking 16' or 14' long.
1/4" 7/16" 1/2" what do you think?
Thanks! The kind of plywood you use will be a factor as far a strength goes. Good quality marine plywood is pretty tough stuff, add some fiberglass and it's going to be stronger for sure. If the boat is on the smaller side, and only used in very calm water with low horsepower motors you could do 1/4 sides 1/2 bottom. With some decent framing installed as well. Bigger skiff and a little bigger motor 3/8 to 1/2 sides 5/8 or 3/4 bottom with some frames of course. We have always built skiffs a little heavier duty, so you can factor that in to your needs. I been thinking about building a 14 to 15 foot skiff out of either plywood or Coosa board for the channel. It might be next winter before we can do it though. Hope the suggestions help, and we appreciate you watching!
I have a small fiberglass hull (15'6" gheenoe classic) that the previous owner installed a thru-hull drain (1-1/2") in the center compartment to make it a live well.
How would you go about patching a clean hole through the hull midship (similar to the holes you made in this video with the faux stringer)? I would love to use this as dry storage instead.
It is the camo color and I would like to TRY and match the gel coat.
You could fiberglass or epoxy the hole. You would usually grind the fiberglass around the hole back 2 to 3 inches on a bevel. Some on the inside, and some on the outside. I hope to do a video on this topic very soon for you guys. Hope this helps and thanks for watching!
havent got metriculation down pat hey - i thought you could do everything 🤣 thx for vids🤙
Haha!Maybe one day!
Great videos! When do you use epoxy?
Thanks so much! We have a epoxy video in the works, so stay tuned!
Another great instructional video.
Do you have any tips when the rigging tube can’t protrude the stringer or bulkhead?
The way I’ve done it is coat the wood with un thickened epoxy or poly bed the pvc in with cabosil thickened epoxy or poly and sand flush. Paint etc. Would be worthwhile to use a small round over bit inside the pvc to eliminate the sharp edge.
Not sure if there is anything else to do in that scenario.
Thanks
We hardly ever take them to flush with the surface, I have gone down to a 1/2 inch or so. You could possibly really radius the inside edges of the pipe, then sand the inside and let the glass roll over into the pvc. I might try that on our demo piece we did in our videos. What you did should be fine though. Thanks for watching!
Thanks for sharing your knowledge!
Could you go into the different types of fiberglass?
Also, which thickness is best suited to which application?
How does layering work? For example, is having one 8 Oz layer the same as two 4 Oz layers?
Thanks again
I actually have a fiberglass selection guide video on the channel already. It is just a few videos back. The thumbnail has a red background with the strips of fiberglass laying across it. Hope that helps. Thanks for watching!
@FishBumpTV thank you, I found it after I made the comment. Great stuff!
I think i'm going to use your tips to build my own waterproof camper trailer. i do have a question, maybe i missed it. i assume i could just drill the pass through holes after the fiberglass has setup but before gell coating correct? Also, you mentioned marine plywood and resins, what are your thoughts on regular (HomeDepot/Lowes) plywood for a small camper box build?
Sounds like a cool project! Just be sure to completely seal the plywood on the pass through holes. The pvc pipe rings are how we would do it on a boat, and has worked well for us. Plywood and resin quality will effect the overall finish quality of your project. I know that the materials we use, and show in the videos have worked well for us, but it is hard to say exactly what to expect if you were to change the formula. I will be doing a resin selection video very soon, and may also add in some plywood testing as well. Hope this helps and thanks for Watching!
