- So, you want to know how a fiberglass mold is built? Well good, because I am going to show you how to get from an idea to a custom molded fiberglass part. Once you understand the basics, the sky is the limit for what you can build! We are building a Key West style Hardtop for our custom built 29 ft hybrid bay charter boat, and you are invited to our family's boat shop for a step-by-step tutorial on how mold building is done. This video is for the DIYers out there that want to build their own custom molded parts, from hard tops and consoles, all the way up to boat hulls!

Hi! Just stumbled upon your channel and man what an incredible good Tutor and tutorial(s) you bring out. Thank you so much! Best regards from Holland, Albert 🇳🇱
Fantastic! Welcome to the channel and thanks for watching all of the way from Holland!
This channel is easily becoming my one of my favorites. Currently restoring a 1973 aquasport 19-6 with intentions to start building/restoring boats full time so basically every video is a must watch for me. All chock full of information that is easily understandable. Keep it up!!!
Wow, thank you so much! The Aquasport sounds like a great project boat!
These types of videos about molds/plugs and that kind of stuff are awesome brother keep it up!
Thanks! Will do! I appreciate you watching
8:30 hey Joe. Love the content! Just a little tip when your using your circular saw, make your blade depth only slightly deeper then the material your cutting. It will not only make it easier to track the line but saves your tables and sawhorses!
Oh yeah, that's a good suggestion. I usually run it pretty shallow, but I must have still had it set for 2x4s. Thanks for watching and commenting
Eres un maestro,un saludo desde Colombia
Another great and informative lesson. Really enjoy and appreciate your videos , because you explain in detail . No shortcuts and distractions (like music). Best this al is done with simple, basic tools. No fancy CNC etc. So, anybody would be able to do what you do. You guys actually inspired me, and I have to thank you.
Wow, thank you so much! Glad you like our video method, and style. We will try our best to keep putting out helpful content for you all!
I like the skiff build idea. It would be cool to see a brand new boat design form start to finish like the 19's you guys used to build. But I know that is a lot of work.
Thanks for the suggestion Kenneth! It would be a lot of work, but I have a idea for a 15 foot v bottom skiff that I have been wanting to build. So who knows, maybe we will do a new design. I appreciate you watching and commenting!
Build a skiff!!! Love the channel!!!
Thanks for the suggestion! I appreciate you watching and commenting!
Hi Joe. I found your channel when I searched for “build small fiberglass boat” so I think building a small skiff would be very cool, especially from a pro. I am a cruiser and I live on a 48 ft catamaran. I also own a couple of hot rods. I think every cruiser should have a nice tender to go ashore, fish, snorkel and tour cool ports. I mentioned hot rods because the traditional deflatable RIB is a horrible boat for cruising. I plan to design something more fun and useful like my El Camino and Malibu to drive as the tender for my cat. Thank you so very much.
Thanks for watching and for the suggestion! I will keep your thoughts in mind when we decide what type of small boat we will want to build.
First of all, absolute best channel on this subject! I Would love to see you pull a mold off that little pirogue you had laying in the shop and demonstrate reproduction start to finish.
Wow, thanks so much! Glad you are enjoying the channel! I really appreciate your thoughts and suggestions! Who knows, maybe we will build a pirogue mold someday.
Yep me too. When I'm competent enough to do so; I want to replicate an aluminum structure to make extremely lightweight skins. There is major supplier of prepreg at the big city so the plan is to rent a moving van and do it out the back when conditions are ideal.
Capt Joe Fish bump family WOW Thank y'all so much for these videos I can honestly say I have never seen fiberglassing a plug or mold this really helps so much just all the techniques tips and attention to detail is a complete game changer the detailed extended videos are fantastic this is what is missing in so many videos we need this time to bring our projects to that finish line so apologies Capt Joe really watching you work and camera man still bringing home appreciate your time y'all have really improved my confidence in this fiberglassing bonding structural world what ever happens from here is a total bonus so to speak! By the way would love to see y'all build a Buskens paddle board one of these days maybe putting your on spin on it ? Y'all take care moving forward in this heat !
Wow, thanks so much for watching and commenting! Glad to help you build your skill set and confidence when working with fiberglass and composites! I wish you the best with any future projects and truly appreciate your support of the channel!
I genuinely love your 'in-depth' content approach, which makes this channel so valuable for me as a DIY amateur: cheers and enormous thanks for making these episodes.
Wow, thanks! Glad you are enjoying the videos and best of luck with your future DIY projects!
Going to love seeing theses series capt. Thanks for all you do. Hope to see the channel grow to a million subs.
Glad you are enjoying the mold building series! A million subs would be amazing! I really do appreciate everyone's support and encouragement!
Thank you for your videos, I been wanting to build a hard top for our Tiara, so this could push me to do the build.....Thanks Again
Glad I could help! Thanks for watching and commenting!
I would love to see you build a 18’ skiff with a decent flair to shed water and a moderate dead rise in the stern. Something that would go in 12” of water but handle a heavy wind chop. Not asking for much😂 . I love your channel and keep up the good work!
I like it! Thanks for the suggestion and for watching!
Cathedral hull.
That would be a very ambitious project.
Another excellent, well explained, detailed and thorough tutorial. Thank you.
I like the cathedral hull designs, but you don't see them much anymore! Thanks for your suggestions and for watching!
This is awesome! I learn something new on every video. Your clips are very well presented, videoed, and so informative!
I completely agree with this comment from below: This is AWESOME/FANTASTIC!!!!
Wow, thank you so much! Really glad you are enjoying the channel!
Your videos are gold! I love that you're not speeding them up, but instead keep talking and share your knowledge. Thank you so much 😁👍🏼
Wow, thank you very much!
That will be lifesaver this summer..
Yes Sir, it sure will! Thanks for watching and commenting Mr Ron!
Catching up on episodes,, Keep that algorithm growing ,,,
Fantastic!!! I love to hear that! Watch time is King, when it comes to the RUclips algorithm. Thanks so much!
Once again- absolutely excellent instructional material. Concise, insightful, and easy to follow.
Y’all make me want to be a boat builder 😁
Wow! Thanks you very much!
i hope people realize the value of what is being presented here. it gives a well presented inroad of principals that can be transfered. I have seen many canopy attepts of boats and they are dogs arses but here gives oportunity to do something worth yor time and money. Also the specific numbers on those 3m sanding blocks ect. thats gold information. greeting from australia
Your comment is much appreciated! Thanks for watching all the way from Australia 🇦🇺!
Nice job capt Joe! When I built patterns like that I would usually double the crown on the pattern because even if you make the mold ridged the part will tend to be more flimsy and naturally flatten out . Yes you can core the finished part etc , but it would be interesting to compare the plug curve to finished part curved!
Popular subject !
Cheers Warren
Yes, I can see what you are talking about under certain conditions, for sure. I do plan on using 3/4 or 1 inch core in this top so as to eliminate any loss of crown. Also this part will be supported centrally from underneath, and will have substantial overhangs. If anything I think gravity over time might even add a little more crown to the part. I will try to note any changes I see to the part once it is installed, and any effects over time. As always I appreciate you watching and commenting on the projects we are working on!
@@FishBumpTV yes since your top is well supported you may not have much flattening. It’s just like 90 deg corners always close up 3+ degrees.

In my opinion I think you may want to consider widening the top just behind your aft most vertical rod holder. I usually make the hard tops 12 inches narrower than the inside gunnell measurement. You will have more shade behind the helm were most like to ride while underway. Just my opinion. Keep up the good work. Enjoy watching your videos! 😊
I hear what you are saying as far as more shade, but I built one this same width on my previous charter boat and was happy with it. The top is a 4x8, any bigger and It would make everything more difficult and more expensive to build as a single sheet of material would no longer make the entire part. We also have a real problem with clients hitting the hardtop with our rods if the top is to big. So it is kind of a trade off for sure between shade and functionality. I would encourage anyone watching to just try and take what they can as far as the process is concerned, and build what suits their needs the best. I hope this helps clarify, and I appreciate you watching and commenting!
Thanks again Captain for what you’re doing on your channel. You promised to do this T top build and you delivered 👏 Just was wondering if you had anyone ask if you would build a Busken 29 for others ? I’m sure it could not be a complete copy because of the Massive Overkill. You could cut the overkill in half and still have the best 29 Center Console on the water!
Glad you are enjoying the channel! Yes, I have had some interest in building another 29. We will see, what happens. Thanks for watching and commenting!
Really enjoy your videos. Appreciate the time you put in. How would you repair chipped gel coat where two colors meet. Video idea for you if run into a gel coat repair in near future.
Great suggestion! It can be done, but is definitely more challenging. I will try to get a video out on the topic for you all at some point. Thanks for watching
Would like to follow a skiff/duck hunting build! Thanks for sharing your knowledge and time!
Thanks! I've done a few small skiff builds in the past and I will consider sharing a video on that in the near future. Thanks for taking the time to watch and comment!
Great video as always, to the point, very helpful and expertly presented. Thanks for putting in all the time to help us newbies, really appreciated!
Much appreciated! Happy I can help you all!
Awesome work. Thank you for the video.
My pleasure! Thanks for watching and commenting!
I think a small skiff project would be great, 14 to 18 feet. Something someone could use fishing or just cruising around in a coastal community with bays and rivers. Something that does not need a lot of horsepower to get up and run.
Ok, great! Thanks for your suggestions and for watching!
Great. Thanks for all this information!!
Glad it was helpful! Thank you for watching and commenting!
I like this I am trying to learn how to build my own forms THANKS
Glad you are enjoying the videos! Best of luck with your projects!
Skiff building! Yes!
Haha! Thanks for your vote!
Don't worry Joe, there are lot of explanations (we appreciate that) but everything is clear!
Haha, awesome! Thanks
Awesome video series.
Glad you like them! Thank you for watching and commenting!
I seen the video of you putting the fiberglass on the plug, I would like to see you build the mold and then build a part and pull it.
I am working on it! Should have a new video out on mold building this weekend. Thanks for watching and commenting!
Good stuff Capt Joe
Thank you so much! I really appreciate you watching and commenting!
Great video
Thanks! Glad you enjoyed it!
please build over the winter a catamaran skiff...if it's affordable, I'd like to order one from you
Thanks for the suggestion, and thank you very much for watching!
Joe is the man
Haha! Thank you!
Thank you 😊
You are very welcome! Thanks for watching!
I'd like to see a small skiff like a FRS-16
Thanks for the suggestion and for watching!
Incredible looking boat. What do you think it cost to build?
A lot!! Haha! It is hard to say exactly, as it was built over several years. Thanks for watching and commenting!
Cool videos. A 14 or 15 foot shallow water cat would be cool. Or a fiberglass jon boat.
Thanks for watching and I appreciate the suggestion!
If you're looking for a nice little project, might I suggest the Harold Payson "instant" catboat (Bolger design). The instant boats are for the neophyte boat builder with limited knowledge, tools, and resources. They are plywood and fiberglass construction, with patterns for cutting out the sections fully drawn (I have them.) Building this boat is on my bucket list, and I would love to assist. I also have the little book detailing its construction. (BUILD THE INSTANT CATBOAT). I would be happy to send you my copy.
Thank you for the suggestion! I have heard of that design, and sounds like it would be a nice entry level build. I haven't decided for sure what we will build, but I am probably going to build one of my 15 ft traditional coastal skiffs. I already have full size patterns and jigs set up for them, and have built several in the past. But who knows, if the channel does well maybe I can build a different DIY small craft regularly. The instant cat boat could be a great option! Thanks again for watching and I truly appreciate your support of the channel!
@@FishBumpTV Thanks. It's a sweet little boat. Hope I have time left to build one.
Ahh man I should’ve studied your videos more before I started my roof lol I’m having a hell of a time cracking my part out lol I finished with 500grit then polished and waxed. Nightmare lol
A stuck part is the worst! The mold, and fiberglass parts building process has some twists and turns for sure! Sometimes, only step missed can throw the whole process off. I hope the work we are putting into the channel is helping folks like yourself. Thanks for watching!
Where do you get the “icebox” or “fish box” foam?
How good are electric fibreglass scissors!
I use a zip snip by worx when cutting a lot of fiberglass. It works great. Thanks for watching!
What would yall charge for a small boat mold ?
Molds are usually quite expensive, even for small ones. I hope by the end of this series that many of you all watching might feel inspired to build your own. I hope the videos are helpful and thanks for watching!
18 ft tugboat
Thanks for the suggestion and for watching!
After 20 mins I was thinking it was, " O' Beer Thirty "...... so you've cut out this plywood & will be fiber-glassing over it? I've seen
some glass work where they used chicken wire or foam blocks but you use wood in the same fashion, guess it's stronger too?
So are ya'll selling many boats or do you do repair work? If I wasn't so old I'd come down & do some boat work. For now I'm
just gonna let you & your brother work too hard in the heat..... kidding, I do like watching. peace
We will be using the plywood as a base for a foam core that will be wrapped in fiberglass. I just uploaded part 2 in this series, I think it will help what we did in part 1 make alot more sense. We are mostly running charters during the summer months, and boat work the rest of the year. Haha, I don't blame you for not wanting to work in the heat down here with us! It get pretty brutal! Thanks for watching and commenting
Cool, I'll be watching & taking notes b/c I'd like to see the processes that ya'll go thru. Who knows, I may decide to build
a small vessel of some sort that can handle a 5hp motor. Don't ask but if/when I do this I'll make it look cool enough that
some red-neck up here on Lake Texoma(7th largest man-made lake in the US). Pretty big lake & I like to create stuff and
that's part of how I landed on FishBumpTV Channel. As I watch I'm sure I'll see places/reasons for wood/foam or for the
chicken wire I've seen other make crap from? I'm 62, ain't gonna start working after retiring from Heating -n- A/C work !
If I did work again down in Florida, I'd do A/C work & make plenty more than doing boat stuff but I'm trained in A/C's.
All that said, I'm down w/ you guys on this journey. I'll go watch Pt #2, it dropped 2-3 hrs ago peace
