    I love watching your videos. Learning a ton. Much appreciate your work ethic and the family heritage for boat building is also outstanding.
    Quick question. I am restoring a 1981 TMI Sailboat (Chrysler design) and have large areas such as in the sail lockers and settees that need mat and woven or 1708 to restabilze the surface to re-gelcoat. I know epoxy covers nearly all, but I would like to use vinylester or polyester resin - For economy of material mainly. How do I know if the original resin by manufacturer is compatible with vinylester or polyester resin?
    Thank you

    • @FishBumpTV
      @FishBumpTV  27 дней назад

      Glad you are enjoying the videos! The vast majority of fiberglass boats ever built are going to be polyester resin. Probably only 5 percent or less are built with epoxy. There is not any easy way that I know of to test your boat, but I can almost guarantee that it is polyester. So using a good quality iso polyester laminating resin or vinyl Ester resin should work well. There are links below our video descriptions if you would like to use the same kinds of resin we use in our videos. I hope this helps and thanks for watching!

    Building two skegs for a catamaran, they are about 27"x12" i made them with coosa board 1/2" that will be the core. They will be mounted to 4"x27" base. Then bolted to the hulls by the base. What fiberglass cover should i use to cover these fins with so they hold well to the base? I was thinking 2 layers of 1708 and and extra 6" wide tape joint of 1708 on the angle area where they connect to the base. There are pretty heavy side loads when sailing and probably when turning too.

    When replacing stringers in an old boat (1979 Pennyan) what resin would you use? I have been told that older fiberglass does not adhere to some materials. Thanks for another great video.

    • @FishBumpTV
      @FishBumpTV  5 месяцев назад

      There is no one resin that is perfect for all applications. Most boats are built of polyester resins. But once the poly resin has fully cured, you are relying on a mechanical bond, vs a chemical bond when adding new stringers, transom etc. As far as secondary bonding goes, epoxy is the best, followed by vinyl Ester, then polyester. They can all be used with success in certain applications. A clean surface, with VERY aggressive grinder marks or tooth is critical. We get this by using a 24 grit disc on a high speed grinder. Then vacuum the surface, and wipe down with acetone. I plan on doing a video on this topic very soon. I hope this helps. Thanks for watching!

    Very useful knowledge. I wonder when using the mat with 45 degree strains, do you turn the mat around when laying more layers, so strains go in different angle to each other?

    • @FishBumpTV
      @FishBumpTV  5 месяцев назад +1

      Thanks! You could alternate layers of 1708 which is 45 degree, with layers of 1808 which is 90 degree. We did that when laminating the hull for our 29 ft hybrid bay. It isn't something you have to do, but it does distribute load in more directions. Hope this helps, I appreciate you watching!

    Ok I will try to make this as short as possible. I am working a Stratos late 80's and they used mostly woven-roven on stringers and I think that is where a lot of failures come from because of where it is woven seems that it created holes that water could get through and the quality of the fiberglassing was poor. In your professional opinion which I value highly! how many layers of 1708 would you use to equal woven-roven on the stringers and other places that they have used it. I want to use only 1708 and chopped strand. My stringers are so bad that there is just a skeleton of fiberglass with a few chunks of wood in the bottom of them. I will use all of the techniques I have learned from you to make this boat better than it ever was. I will be using only Coosa board for it. To sum it all up I think you have the best boat repair DIY videos on RUclips and I commend you for starting this channel. Thanks so much and have a great day!

    • @FishBumpTV
      @FishBumpTV  Месяц назад

      Glad you are enjoying the videos on the channel and finding them helpful! We used 3 layer of 1708 on each side of the Coosa stringers on our 29, and it is very solid. Be sure to consider the quality of the resin as well. A quality isophthalic polyester laminating resin, or even better a vinyl Ester resin is really going to help improve the strength and quality of the job. I hope this helps and wish we the best with your restoration project!

  • @rickeyholtsclaw7764
    @rickeyholtsclaw7764 Месяц назад +2

    Rookie here: It is my understanding that "mat" does not work well with epoxy due to the binders in the mat; therefore, can 1708, which does work well with epoxy (?), be used exclusively without applying the mat as a base? I'm preparing to install a reinforcement transom in an old I/O that I'm transitioning to an outboard motor. I'm using 2-pieces of 3/4" plywood for the project and will combine that with the transom already in place....the objective is to extend the transom to the bulkhead and pay special attention to glassing-in the transom ends to the fiberglass hull. I've have already ordered 90-feet x 50" of 1708 and a couple of gallons of "Total Boat" epoxy and slow hardener. I'm in SW Florida and the temps here are now in the mid to upper 80's during the day - humid. It is good protocol to use 1708 exclusively with the epoxy to both seal the plywood transom, add strength and integrity to the wood while also feathering the 1708 to the fiberglass inner hull to counter the forces of the motor on the transom? I'm a little confused concerning the application of mat or strand, which requires a polyester resin (?) and 1708 which works with epoxy for strength. Thank you for your help...much appreciated. Your videos are invaluable.

Epoxy doesn't have the solvents in the resin that dissolves the binders in the mat, which makes it a little more difficult to work with. Most 1708 has a layer of 3/4 Oz csm stitched to the backside of the main 45 degree glass strands, but it is not held together with binders like pure csm is. 1708, 1808, and 6 Oz finishing clothe are the most popular fiberglass fabrics when working with epoxy resins. I hope this helps and best of luck with your project!

      @FishBumpTV  6 месяцев назад +1

      Thanks Capt! Sure, the 6oz fiberglass cloth is generally used for just sealing or finishing out raw wood. We use it in applications like epoxy over plywood skiffs for example. It is quite expensive per pound compared to other fabrics and builds up thickness very slow compared to csm and roven or biaxials. Hope this answers your question. Appreciate you watching and commenting, it helps the channel!

    Thank you for your videos. I have cut the back out of my '77 Grady White 17' (bad transom). I saved the back panel to put over new plywood. Should I use CSM or 1708 (have both) to cover the cut? Will grind a bevel and plan to use polyester resin then cover with gelcoat. Any help would be appreciated.

    • @FishBumpTV
      @FishBumpTV  4 месяца назад

      Glad you are enjoying the videos! The 1708 biaxial is going to be the stronger of the two materials. The csm is good for initial bonding and finish cosmetics. You should use the materials where there best qualities will work for you. We plan on doing more structural fiberglass videos soon as it is much easier to discuss best techniques and options that way. Hopes this helps, thanks for watching!

    I wrote you before about bonding an epoxy coated material to a polyester fiberglass hull. I am now preparing to bond two pieces of epoxy coated material together. Your video shows the use of 403 and 406 into the resin. My concern is added thickness/separation . My overall thickness is critical. Why not just use epoxy only for bonding?

    • @FishBumpTV
      @FishBumpTV  3 месяца назад +1

      The thickened epoxy resin is stronger and stays in place better than unthickened epoxy in my opinion, but I am just showing you guys how we do things in our shop. If you don't think it will work for your application you should do what you feel most comfortable with, or do some test panels to see if it will work for you.

      1708 biaxial works good with epoxy resin as does the 6 Oz clothe. 1708 is thicker, heavier material. 6 Oz is smoother and lighter.

    Hey Joe a 3' deep 16' x 40' barge type bottom for a house boat. How much resin would I need please.

    • @FishBumpTV
      @FishBumpTV  5 месяцев назад

      That's a good question. Different Temps, plywood, type of glass fabric and how many layers as well as the person doing the work could all have an effect on how much resin you could use on a job like that. You can usually figure on approx 2 to 3 Oz of resin used per Sq ft covered with 1 layer of 1708 biaxial. Based on your Diminsions you are looking at 880 or so Sq ft. Let's round up to 900 Sq ft x 3 Oz per Sq ft on the high end would be 2700 ozs divided by 128 Oz per gallon would be 21 gallons of resin used approximately for one layer.I would recommend at least 2 or 3 layers of biaxial with a finish coat of csm or mat as well, for a vessel this size. This is just just my opinion of course! And a ballpark estimate. You should do your own calculations and research, as well as talk to your local fiberglass and resin suppliers. Safety is always a factor on a project like this so you may also want to pay for some more technical advice from a boat builder marine surveyor or boat repairman in your area. Hope this helps, thanks for watching!

    please break down the cost comparison between mat and 1730 including the strength vs cost of resin . I am sure that in your business, the performance vs the cost comes into play. please note that less resin is more strength per pound of product. The strongest layups are vacuum bagged to minimize resin.

  • @davidross7791
    @davidross7791 5 месяцев назад +1

    I may have missed it, but when you say "primer coat" are you allowing it to completely dry before adding layers? Also, if you are allowing it to fully harden, are you abrading the primer coat before starting the next step? Again, apologize if I missed it but I am very new with fiberglass and there is so much information and techniques to learn. Thanks for your videos, they are the easiest for me to follow/understand than some of the other creators.

    • @FishBumpTV
      @FishBumpTV  5 месяцев назад

      Yes, I usually let the primer coat cure. Then you can sand it lightly just to knock down any small imperfections. Glad you are finding the videos helpful, and I appreciate you watching and commenting!

    • @philhansen933
      @philhansen933 3 месяца назад

      I heard in order to add a layer to old cured you need to sand to abrade. But with "new" there is an open time when you can apply another layer and the epoxy will adhere. Is this epoxy and not a poly resin issue, or not an issue at all?

      Yes, you can use chopped strand mat if you are going to use polyester or vinyl Ester resins for your job. If you are going to use epoxy resin, I would go with the 6 Oz clothe or 1708 biaxial. I hope this helps and thanks for watching!

    Hey Joe, what glass and what layering would you recommend to replace my stringers with styrofoam or EPS?

    • @FishBumpTV
      @FishBumpTV  5 месяцев назад

      There are many different ways stringers can be built. I imagine the original stringer were lumber or plywood and they rotted out. If that is the case I would go back with Coosa board in the same thickness as the original, or slightly thicker. Two layers glued and screwed together with with the joints staggered is the way to go. On most boats 3 layer of 1708 with the edges staggered works good in most cases. We have a video or two where we are working on the stringers and glassing them in our boatbuilding series that might be helpful. Stringers are not an area to take shortcuts or skimp on materials, so always a good idea to go on the heavy duty side of things. Of course these are just suggestions, and every boat is different. Hope this helps, and thanks for watching!

    you mentioned on working with fiberglass, kay down CSM first then woven roving, would it be safe if we do CSM then woven roving then another woven roving then biaxial or just alternate the material like CSM then woven roving then biaxial? thank you. please reply.

    • @FishBumpTV
      @FishBumpTV  6 месяцев назад +1

      The only fiberglass fabric that you should not laminate on itself over and over again is woven roven. If you have csm and roven to work with, you would always start with csm then roven then csm etc. You would always want to start and finish with csm on any project when you are also using roven. With 1708 and 1808 you can stack them on themselves over and over again with no problem. With 1708 and 1808 you can use csm on the last layer as a better cosmetic finish. You can also use layer after layer of csm stacked on itself with no bonding issues, it just will not be as strong as alternating layers of csm first then roven then csm. You may want to watch the video How to fiberglass over plywood, which we just did it should be helpful.. I also offer consulting on an hourly fee for folks that need more of my time. Hope that helps ,and good luck with your project!

    Do I need to turn my fiberglass boat over to do repairs on 1ft crack below the water line. Also, do I need to use epoxy resin?

    • @FishBumpTV
      @FishBumpTV  5 месяцев назад +1

      It is easier to do repair work right side up if that is an option. If it is a smaller boat, I would turn it over. If the damage is below the waterline that makes it more critical, Could be structural damage. Damaged glass should be removed, and new glass applied. We don't currently have a video detailing that process, but hope to have one soon. Yes, epoxy is the premium choice for that kind of repair, followed by vinyl and polyester resins. Hope this helps, good luck with your project!
