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

[@FishBumpTV]

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!

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!

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.

[@FishBumpTV]

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!

[@christopherbowersdresser4188]

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.

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.

[@FishBumpTV]

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!

[@BroRebel]

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?

[@FishBumpTV]

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!

[@benmac1395]

Awesome video as always. Keep up the good work! I’d love to see a transom repair/replacement.

[@MichaelConquest]

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.

[@FishBumpTV]

Thanks so much! I will try to get a transom replacement or something similar for you guys soon.

If this guy sells pre made boats and he makes them all like this save you Pennie’s and by his boat. By the time you do all this you will have 10’s of thousands of labor hours involved.

[@FishBumpTV]

Thanks for the comment! Glad you approve!

[@leerobinson7086]

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. 😊

[@FishBumpTV]

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!

[@ps7462]

@@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.

[@FishBumpTV]

@@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

[@streamin2605]

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?

[@FishBumpTV]

Thanks so much, I appreciate the tip! I will try to work on a resin additives and fillers video for you guys.

[@davidtornberg8060]

Would you say using plywood for stringers is better then using lumber? My ski boat has one long piece of wood. If you use plywood how would you join them together?

[@FishBumpTV]

Both lumber and plywood can be used for stringers. Two layers of 3/4 inch marine plywood laminated together to make a 1.5 inch thick stringer will usually be stronger and more stable than a piece of 1.5 inch thick lumber. Also, Good lumber can be hard to find these days, but marine plywood is a little easier to source. Of course you could also go with a product like Coosa board, which we used when we built our 29 ft charter boat. We have lots of videos of the boat build that shows the Coosa stringers. We will be posting a new video soon showing how to laminate marine plywood to make a stringer. I hope it helps. Thanks for watching!

[@colegardner2346]

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!

[@FishBumpTV]

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!

[@FishBumpTV]

[@walkertongdee]

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.

[@FishBumpTV]

Thanks for the comment and for watching!

[@chucklenz9011]

If the mat kind of melts how does it lend any strength to the overall assembly?

[@FishBumpTV]

The resin melts the binders in the mat or csm, but doesn't actually melt the fiberglass fibers themselves. As a side note, csm has strength, but not as much as biaxial does. Csm bonds well, and leaves a nice cosmetic finish. We usually use the two together when working with polyester resin to get the best results from each one.

[@cameronmccarroll9549]

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 .

[@FishBumpTV]

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!

[@MichaelConquest]

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.

[@FishBumpTV]

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!

[@MichaelConquest]

Awesome! I'll definitely check that out.

[@DondiTrent]

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!!!

[@FishBumpTV]

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!

[@michaelanderson1947]

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?

[@FishBumpTV]

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!

So if you are glassing a half round as in my plywood bow pulpit do you need to cut a bunch of pleats to make it conform to the radius ? Thank you for sharing your experience 😊

[@FishBumpTV]

The pleats make it easier, especially on sharp turns and corners. On a soft radius you can usually use less pleats. I recommend making a dry fit of the fiberglass material before any resin is applied, the material will show you what it needs. Hope this helps, thanks for watching!

[@JohnColeman-ul5rj]

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!!!

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.

[@FishBumpTV]

Great tip! Much thanks!

[@sz4179]

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

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.

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 ?

[@FishBumpTV]

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!

[@jaisonlee007]

Can you mix your own pro strand type putty with resin ? Like mixing in milled fibers, cabosil and Qcell?

[@FishBumpTV]

Yes you can, and I do sometimes. But I really like the consistency and convenience of the pro strand. I will be making a video on mixing putties soon. Thanks for watching!

[@jaisonlee007]

@@FishBumpTV couldn’t find that specific stuff locally. There are other brands of short strand filler that they sell but not sure if it’s similar.

I will be doing a video on different resins selection soon. Hope it helps, thanks for washing

[@Premier-Media-Group]

Hey, Joe - maybe do a video about repairing damaged (rotten) section of wood? Many of us are doing repairs vs building brand-new. Now I'm guessing most steps are similar, but would be nice to see a transom repair or deck section replacement. Thanks!

[@FishBumpTV]

Thanks for the suggestion and for watching!

[@mikeyadrick5154]

I feel your info is very important to the overall project--you folks appear to do Custom boatbuilding rather than Production building--therin lies the fact that you are giving out more information to do a much more thorough job than a production shop that cuts so many corners to Get The Product Out the Door! But as you have stated , your videos are longer--because there is so much more information. I tend to demonstrate the same problem in trying to teach the skills necessary. Not wanting to lose the Attention Span of the student/viewer is the Challenge. Good Videos!-----Mikey, Belfair, Wa

[@FishBumpTV]

Thanks for your thoughts and for Watching!

[@fishhuntadventure]

33:19 Don’t worry about the length of the video. The person that wants a shorter video is sitting in a recliner and thinking about the next donut or nervous about having enough time to go buy another 12-pak of brewski imho; they never make it out to the garage or driveway to work on anything.

[@FishBumpTV]

Glad that you are enjoying the longer format videos! You probably have a point there. I appreciate you watching and commenting!

[@nathanmeier2908]

Thank you for sharing your skill ,knowledge, trade, extremely useful info. By far the best hands on how to work with fiberglass videos out there. Great content very well explained.

[@andrewnajarian5994]

Just a tip, popsicle sticks and tongue depressors work great for applying putty’s and such in tight spaces. They’re dirt cheap and disposable. I keep large bags of each in my shop for just this type of thing.

[@FishBumpTV]

Great tip! I do use them sometimes, but not in any recent videos. Thanks for watching and commenting!

[@sebastientillet2054]

you don't have problems of detachment between pvc and polyester resin cause of vibrations ? Why don't use polyuretan mastic that are very more elasticity and glue very strong on pvc ?

[@FishBumpTV]

No, we have never had any problems with it failing. We always thoroughly clean the pvc with acetone first, then sand the surface very aggressively. And we are only using the pvc as a conduit or a rigging tube for wires and hoses. But I recommend that people should do what they feel comfortable with. If you don't like or agree with what I show, then you shouldn't do it. I hope this helps and thanks for watching

[@jimmyghersi]

Your videos are excellent, I appreciate the fact that you take the time to explain and illustrate each procedure and the materials

[@FishBumpTV]

Thank you very much, so glad you are finding the videos helpful!

[@lectro88]

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.

[@FishBumpTV]

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!

[@microadventures8671]

[@estuarypest5982]

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

[@FishBumpTV]

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!

[@s8ang]

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.

[@FishBumpTV]

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!

[@TheRedsuper1]

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?

[@FishBumpTV]

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!

[@bertherta494]

Here in the U.K there is 2 types of matting available, Powder Bound for epoxy resin. Will this matting conform to different shapes like the styrene matting does with polyester resin? After the wood is primed and gone tacky could the PVC tubes be installed instead of waiting for the primer coat to dry over night. Another question is, how would a weep/drain hole be installed in a stringer or bulkhead, would you use the PVC tube method demonstrated here in this video or seal a weep hole in a different way.

[@FishBumpTV]

Yes, I wish we had the epoxy compatible csm here in the states. I like for the resin to at least tack off before installing the pvc pipe, but don't suppose you have to. Yes, you could use the pvc pipe as a weep hole in a stringer or bulkhead, in fact that is how we did it in the build of our 29 ft custom build. There should be some footage of that in the 29 build series videos. I hope this helps and best of luck with your project!

[@Testfrpfr]

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.

[@FishBumpTV]

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

[@alexsails80]

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

[@FishBumpTV]

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!

[@debrisbox]

Hey Captain. That green putty, does it chemically bond to the PVC pipe or is it a mechanical bond due to scuffing it really well?

[@FishBumpTV]

It is a mechanical bond, that's why cleaning and sanding thoroughly is important. This is the method we have been using for years on our boats with good results. Hope this helps and thanks for watching!

Next time place that polyester putty into an open syringe. Hold the pipe in place with a piece cut out piece of cardboard that fits snuggly to the pipe. From the opposite side push the syringe into the gap and posh the plunger .The gap will fill in solid 1st time. Think like you are filling it with a caulk gun.

[@FishBumpTV]

Thanks for your thoughts, I appreciate the suggestion!

[@choimdachoim9491]

I assume wet wood decays due to bacterial action and I wonder if soaking the plywood for my transom replacement with bleach and letting it dry would help protect the wood if the fiberglass covering is breached.

[@FishBumpTV]

I have never heard of doing that before, it is an interesting thought though. My concern would be that the bleach could affect the bonding ability of the resin.I know that as long as the wood is completely encapsulated it will last a very long time. Thanks for watching!
