[@jeffweaver6827]

I'm an aviation technician for a major airline whose been trained in composit repairs. You are correct in starting small and moving to large. That is the correct required FFA repair layout for fiberglass and carbon graphite structures. Depending on the sanding taper and layers of fabric of the damaged area the replacement cloth bonded to these areas are the strength of the repair. for example if you have three layers of fabric you need three layers of fabric for the repair. The outer layer that is fared into the outer layer is used to protect the actual structure repaired fabric. Your doing a good job - excellent explanation.

[@paulgush]

Is that with vacuum bagging?

[@danielldecamp7516]

You only live once brother! Find some time to enjoy the water with your kids and create memories! It's important too! Much respect, love your videos and you blessing us with knowledge. 😎👍

[@davidchekas9185]

Daniell DeCamp Agree 1000% it is more important than putting weekly KZbin videos or just about anything else...Spend that quality time with your family on the water...The rest of us can hang on hold, I bet most of us would be thrilled for you if you did that and then did a Video on the great time you had with the family...

[@wallyworld817]

Memories the only thing you take with you when you pass a way, extremely important oh yea the most important thing you leave behind. 💯

[@the_saint_1]

Just a thought. Since you help so many around the world with their boat projects. Maybe it would have been an idea to have a board with pictures of projects that have been realized thanks to you in your workshop. Both to encourage you and others who are working on their projects. I just finished a boat that I would never have been able to complete had it not been for you and your KZbin channel. All thanks to you Andy. Would love to have seen a video of you and your family and friends on the water as well. Remember to have some time for you and yours as well. Life does not have to be just work.

[@borismartinez6475]

I was going to comment about the same 2 subjects, but you you put it in a perfect way, so I am with you there. Also, very nice idea of having pictures of the boats that have been repaired thanks to Andy and his videos, I did mine thanks to him, also. Cheer from florida.

[@TechyBen]

I filled in an old exhaust hole perfectly from following these tutorials (we will not talk about the *other* holes I filled less than perfect ;) ). So could work out.

[@6speeddakota]

I restored my 1959 Glasspar Trident and watching boatworks today has always been amazing when it came to laying up glass, sanding, fairing, painting etc. I would gladly send in a picture, I totally agree that he should do this.

[@JonDunnmusician]

One of best comments ever added to KZbin

[@tedchansen]

I like this idea! My boat rebuild relied heavily on the knowledge I learned here.

[@richardvargas9224]

Best boat repair channel on the tube!!!

[@puntagordapanga1295]

Andy, you have taught me everything I know about boats and I have rebuilt several boats. I almost cried when you said you have only been on a boat 2 times in 20 years. All my boat building has been to enjoy the boats on the water with my family. PLEASE get out on the water more. It is good for your soul. Thank you for all your videos.

[@JonDunnmusician]

Awesome comment- Andy deserves 6 months at least on water!

[@wilfdarr]

Agreed.

[@jehines3]

Andy, I love your channel and await your new Content each Sunday. You’ve done so much to help with advice for my projects. Do me a favor. Finish the Bertram, take your kids on the lake, crank up Cat’s in the Cradle and remember why we work so hard. Make as many awesome memories with your kids in that Bertram.

[@robin8559]

My dad gave me my first boat, and it was a beater. But I loved it. He always said that it changed my life. Kept me out of trouble and gave me the the feeling of being grounded with the earth when I'm on rhe water. I wish that feeling for everyone young and old.

[@luckyone9272]

Thank you for explaining why your prefer to laminate small to large. It does make more sense but when amateur's like me see different schools of thought we start to question why. Knowing the reasons experts have for their methods helps us understand the differences and enables us to feel that whatever method we chose to use it is a well informed choice. Enjoy the time with your family every chance you get. I wish I had listened to that advise much more than I did.

[@bowersish9489]

I just discovered your channel and you've given me years of content to watch. Thank you so much

[@chrissmith6133]

In 45 years always done small to large, never had a failure in thousands of large blisters to large areas for multiple layers of layup for the repair. Gives you more control for an air pocket developing a few layers down when rolling it out, and controlling resin. As you say less fairing, in most cases sand then skim for air holes, depending on the surface, location, and the detail needed so it doesn't look like a repair.

[@TechyBen]

I guess as long as the gradient sanded down before the repair is 12-1 then it's still a structurally strong repair.

[@Duh6666666]

It just appears so logical to me.

[@benmac940]

Thats what I've always been taught and what I've always done too.

[@5766546]

I really enjoy this channel and agree with a lot of what you have to say; however, having work in the composites industry for four decades I always start large to small. I say this after having to supply test laminates for certification of repair procedures where we utilized various materials and techniques. The large to small always showed superior physical properties. It's really nice when the client pays to provide you with laboratory confirmation of your craftsmanship. Keep up the good work...

[@imbhvn7258]

Andy, your an absolute champion, ill always recommend people to watch your videos if they ever need help with something! You have taught me alot over the years! I vote to keep the Bertram, start getting out on the water with the family more often. Time is precious, and money can't buy happiness.

[@franciscosduarte]

Hello! I built a 16ft wooden boat from scratch at a boat builder when I was 19yo, as a woodworker's apprentice. A rebuilt replica of my father's old speedboat (that was totally rotten). No fiberglass, just pine, plywood, and a 138hp volvo penta. That's my experience. After being an airline pilot for 10 years, I had to quit and re-invent myself into leather works, then upholstery, then eventually someone asked me to re-upholster his fiberglass polyurethane boat... I thought... yes, I can do it! But... no re-upholstery... Extras: "Now the floor appears to be rotten, and, can you move the seats back so I have 1 extra seat?" Well, I saw a few of your basics videos, bought some poly resin and fiberglass mat, plywood, etc, and I just have to say... Thank you! Me, being so procedure directed and specific about all the details, I loved that you also are, and I learned a lot from you, just in a day. You are saving me! ;) Keep up the good work. Be happy and enjoy life with your daughters and family!

[@PepperSportsCards]

The way you've always discussed the lamination buildup makes perfect sense to me as well. I'm in the middle of a transom replacement project and the thought of there only being one point of contact between layers boggles my mind. As always, enjoy your videos and get so much out of them. Thanks!

[@daviddickmeyer5231]

Your lay-up schedule makes perfect sense to me and that is the way I’ve always done it also. It’s a visual thing too, as you can actually see each layer as it builds up and outward and attaches itself to the substrate. Great video Andy. I’m enjoying every episode. Thanks.

[@paulhoare8531]

I like the fact that you talk all the way through your videos and explain exactly what you are doing and why you are doing it, keep up the good work mate.

[@archiecassidy8151]

Those girls will grow up sooner and before you know it they will have other interest and other friends and right now is the time to be bringing them out and letting them enjoy being on the water. To be honest I was surprised you don't go boating with them. Now is the time not years from now. Ask them if they would want to go out boating. I love your show and love the new project and format. Work is work and has no value except one day closer to the grave but the time with those girls is priceless I mean priceless.

[@janrupus9585]

Dear sir, Thank you for your great video's! I have been restoring my 36ft SY bottom-up for a couple of years now and I could never have gotten this far without your instructions. Little-to-big: Another reason for hand lay up small to large: in case you are laminating in bulkheads, stringers etc., it is easier to apply the more narrow fiber cloth over the joint first - even if there is already a tapered spacer and/or fillet in place. As of the radius is decreasing by each added sheet, it becomes easier to apply the next (wider) clothes. In case you laminate on a vertical joint, or even above your head, the weight of the first narrower cloth is less so it remains in place more easy when you apply it on the tacky hull surface. Finally, the resin added to the smaller cloth is unavoidable spilled a little on each side of the cloth, making a perfect preparation for the wider one. As to the (non) use of peel ply I can't agree with you. Basically you are selling (skilled) man hours. The more you can make in a limited time, the more you can earn (or take a day off). In my concept using peel ply tremendously reduces the working hours spend on sanding and other prep work (such as taking off the amine blush), especially in places hard to reach. It saves your lungs and it reduces the stress load on your muscles needed during sanding. Please do reconsider.

[@jcdesignsandboat-works8290]

Well done again Andy! Not that you need any affirmation, but I perform repairs in the same way and for the same reasons as you do. Always have and always will. Good luck with your surgery, I have a different one coming up soon myself! Sending prayers your way for a speedy recovery!🙏

[@jimmorris8158]

Please don't listen to the peopl who say you talk too much. You're doing great! Thanks

[@Nilezy]

I commend you Andy for your comments on Peel Ply. The industry, commercial and DIY for any composite work is highly wasteful. Not entirely due to practices, but through methods for various reasons and of course, choice. The more thought that is put into work on composites to reduce waste, the better we and our future generations get to enjoy our planet.

[@donb4386]

Thanks for doing this. I very much appreciate your reasoning for the products and procedures you prefer. Prior to watching your videos fibreglass was pure voodoo to me. Now, with a little care and diligence I can tend to the simple stuff.

[@martygrove3986]

You definitely don't need people telling you what to do (i.e. critiquing how much time you spend on the water). Follow your heart. If helping people w/ boatwork (plus wood-working etc.) is what "floats your boat", then so much the better for the rest of us who appreciate such help and accrued knowledge/experience. I see plenty of evidence of how your channel has benefitted people worldwide!

[@michaeltowler2632]

A surski and boatbuilder told me that gell coat with wax goes yellow eventually, if you want to keep it white the same as the hull you use none wax gell coat and you have to put something on to keep the air out ,he had big sheets of some sort of film as well as the stuff you spray . he said for small home repairs cut an platic ice cream carton up and strap it over the repair with tape and that would do it ,also flatting the surface as well

[@gdk414]

Love the channel! Ive always done glass like you. Just makes sense and has never failed. Just filled my 1964 donzi dash gauge holes that way! Worked out great!

[@craigandg]

I just finished 11 months of recovery from rotator cuff and bicep tendon surgery. Prayers for your speedy recovery.

[@richardwhite8406]

I totally agree with doing a fiberglass repair with small pieces first building up with larger layers, it provides a much stronger bond and easier to fair out.

[@Kiwigd]

Andy, hi from New Zealand..I really appreciate your wisdom and advice, as someone working with fibreglass every week , sometimes every day of the week, your guidance and tips are always relevant to me. Please do enjoy some time on the water with your partner and kids. You’re actually investing in their memories as much as your own. 🤙

[@tedbower685]

I' had both shldrs done, you won't be sorry, don't overdo things and do the physio, i''ve learnt so much from your videos going from small to lge makes good sense beginning of this year i new nothing about glassing now ii do all my boat repairs and even fix canoes for people. there is one thing i would like to ask in Australia gel coat is gel coat but waxed gel coat is called flow coat theyt don't seem to make the same destinction in the the USA .

[@robertschulke1596]

Re: hole filling laminate sequence: Consider that the fiber provides tensile strength to the layup. Look at a cross section and consider the glass as stress lines. If you fill a hole big to little, the stress lines are no longer smooth and continuous. When Force is applied, this creates stress concentrations which become points of failure. Filling a hole little to big keeps the glass all in line with a nice tapered scarf to spread stresses. Do samples, cut out a strip across the middle of each, and bend them to failure. Big to little will not bend in a smooth arc, and will fail sooner.

[@wilfdarr]

Thank you! I knew in my gut that method didn't look right to me, and you putting it that way is a major 💡! Of course small to big is the right way to do it and now I can explain why! Thank you!

[@bobcornwell403]

I agree with your small to large laminating approach. The only time I would deviate from it would be if I were installing an eye-bolt. Then, I would make the local reinforcement laminate from large to small.

[@dirt186]

Hey Andy! Can you please do a video on different types of fiberglass cloth and when you should use them?

[@chrish2996]

Hi Andy. Selling the Bertram will mean the new owner gets a fantastic boat, you pay off the shop means less bills and an investment for the long term. Your channel is awesome. Great video thanks.

[@kevinjamescerce]

I have been doing glasswork for a marina for a decade. Self taught so research is everything. My first jobs were small to big because that’s what makes sense. Then I saw the complete opposite in the west systems manual so I began my research. David koba and Fernando Garcia Alonso left comments here that state why big to small is apparently the right way on boats. No clue for planes I’m in the marine business

[@PreacherwithoutaPulpit]

I have to agree that working from smaller to larger just makes more sense. Each layer will have direct contact to the original structure or layout. It also makes sense that this would as a result require less sanding as each layer is filling the hole and building up. Where as starting larger, like you said means the whole patch will only be as strong as that first layers bound and would also result in a much thicker build up. Man, I also agree that trying to put this idea into text is a pain in the you know what. I always go smaller to larger and the results are always what I'm looking for if I do it right. They also require less sanding and yes I've tried both ways... Oh and I wanted to add as an old fart with three grown boys. I'm so happy to have the memories I created with them on the water. Trust me when I say this, make the time somehow to get out on the water with your children while they're young and they will thank you for it when they're older. My oldest is 35 now and he still talks about how much fun he had as a boy out on the lake with his family and my other boys do to. Don't take the chance that in the future you may regret not doing it because I can kind of hear that in your voice now when you talk about not doing it. I know there are probably a hundred things screaming that you can't make or don't have the time. Even if it's only a day or two a month for a few hours or less if it has to be, please find a way to make the time. The time with our children when they are young flies by so fast and if you're not very careful you'll miss it...

[@backforty2]

It is good to hear your opinion on the laminating schedule. The only place I have seen it suggested reversed is the Gougeon Brothers Fiberglass Repair Manual. All the other manuals I have read suggest start small and final large. Maybe they were thinking the epoxy bond made this work? I use only epoxy for all my projects, but I do it your way most of the time.

[@josh.kaptur]

pretty sure he's referring to West Systems, which obviously has quite an audience. They say large to small.

[@BrindiSea]

@@josh.kaptur the Gougeon Brothers IS West System.

[@benmac940]

@@josh.kaptur I'm not sure, I've always started small and worked up, never even considered starting big until I saw quite a number of people doing it that way on here, though this is the closest I've come to any sort of reasoning.

Brilliant attitude re peel ply!

[@chuckscheaffer4694]

Thanks Andy. I always learn from your videos. FWIW, I prefer the large to small lamination method, and I use West System and PeelPly too. But I send others to watch your videos as I consider you the guru. Stay warm.

[@richardcorcorran8965]

You work for yourself and your family. Creating those family moments on the water will be priceless. Don't sell

[@hnphnp1]

Interesting answer to the peel-ply question. My take on the matter is this: peel ply is pricey, but so is gelcoat. And sandpaper. And resin. You'll save on all three, so it might be a wash. Landfill the peel ply or landfill the sanding discs and dust. But to each his own. Keep on with the videos. I'll keep watching.

[@tomharrell1954]

I am with you! Small one first! Big one last! I use the gelCoat to cover too! I like it!

[@ScinnerNo1]

Boat repair shop from Sweden, we also start small when patching holes and if it's a thru-hull we repair from both sides 50/50.

[@flyingfifteen2745]

HIPPY boat builders unite!! 👏 I agree 100% to avoiding anything adding to a landfill. Love the video. Great info.

[@robhandford3006]

Think about this……peel ply is just a piece of fabric wetted out with resin. I get it, it is a one time use item. What about the mixing cup, stir sticks and brush that you use to apply gel coat? They all go to the same place. I agree, this line of work produces tons of waste and it’s awful to look at. To me, cured resin soaked fabric is better than hard plastic 2.5-5 qt mixing buckets getting tossed after one use.

[@dwayneroberts6616]

Ooh now I get why you use gel coat before sanding. It's for speed and us as well as a way to cure and sand the surface of a non wax gel coat. I am working outside so I was going to use the spray because my hull is white on the bottom but I think Im going use gel coat.

[@donazzopardi8747]

[@freefallfool66]

Thank you for all your great advice and videos. You've given me the confidence to tackle repairs on my 1985 Grew

[@JOEGGGJOE]

I go back and forth with smaller to bigger/bigger to smaller repair. I actually think bigger to smaller is better. I just feel like if the smaller patch is rite on the layer or just over it a little bit, that may be a weak point if it gets hit in the same spot. Just feel like the bigger patch will cover the whole area & if it will get cracked from another hit, the crack will only go so far. But you do have a good point. Keep up the good work.

[@howechilds5060]

Thanks for answering questions! You must have answered or shown how to fix my issue in the past. I have 1/2” drill holes in my transom that were put there to squeeze my transom to the outer hull shell when I replaced the transom. When I removed my transom I did it from the inside. If you have a video showing the best way to fill holes that size that would be great!

Pro. Boat builder had an article on composite boat repair featuring an repair instructor from the airplane field. Their tests showed large first best as there is less air and or resin trapped at the edges of each layer.

[@toxitobi]

Further up there are some comments from airplane mechanics stating the opposite. On another note: if they got trapped air or not properly cured resin they did something wrong anyway.

[@WildRoverSailing]

Thanks for helping to reinforce my argument on the subject of starting small when laying out the mat. Hoping someday you will take on a sailboat grounding grid repair.

[@drummer0864]

A long time ago, a body man that repaired Corvettes for a living told me the exact same thing about laminating the glass. Start small and go bigger on every layer. A flatter repair and less sanding. A car body vibrates and flexes continuously. A patch laid up big to small will not stand up to those stresses and will crack, right along the edge of the repair unless you do it the correct way. That's the way I've done it ever since.

I'm with you on the layering of the patches of fiberglass, starting big dosent make sense and during any other repairs being welded or wood working you always start small and work your way up.

I have worked on V22 Osprey for 34 years all composite repairs are small to large per aeronautical engineering. You do it the right way. I see other people do it the opposite.

[@n6y6h6]

My practical handbook about laminating says the same...start with the smaller patch and work your way up...

[@TechyBen]

Wow, I've seen opposites. :/ I guess you do really want the largest part contacting the existing structure. But could use some sort of snowflake shape if you want multiple layers to have multiple points of contact with the original structure too. I wonder if it's worth making a few example parts and testing the strength? One being small to large, one being large to small, and one being a mix of both as you would cut snowflake shaped patches, so they interweave.

[@glennl9630]

This guy is so informative!

[@fernandogarciaalonsodeflor8073]

The most important unions are the ones that involve the original laminate. Most delaminations occur at the perimeter of the cloth. Once you have a small delamination or blister, it will act as a seed and it will grow into a bigger problem. when you go from small to big the perimeter of every circle will be in contact with the original laminate, so you will have a much bigger chance of small delaminations that will work as seeds.

[@BigOilBeGone]

Andy could let us know where we can get the bottle you use to measure hardner and maybe do a video on how to use it?

[@ivandepasquale2717]

Dear Andy, probably many other people had already done the same question. I've seen many video of yours, but I can't find what I would like kindly ask you for. I'm Italian and my English is hard; perhaps this is the reason for not having found the answer. My question is: if, in a restoration below the waterline, I don't totally remove gel coat; but only where there are craks, and there I go on with sanding, laminating fiberglass. What type of substance should I use to fairing, suitable with remaining gel coat, and with next paint? Meanwhile I have understood that: 1) epoxy putty doesn't agree with polyester paint; 2) you like gel coat vs. paint; but I'm a beginner. Thank you very much.

[@TammyNorie]

Shoulder problems are really disabling. I know from experience. I wish you an easy surgery and swift recovery!

[@christopherbrossart9271]

Another awesome video. Thank you.

[@RA-gk5zg]

Large to small has the advantage of reducing loss of strength if you sand into the patch. Over sanding will only feather the edges of each ply in the patch. More important is prep before doing the patch. It doesn’t matter which method you use if you have a poor bond.

[@freddynews6478]

Just got to comment again. I’d like to see you finish the small red boat thus winter and in the spring take the girls out once in awhile. Don’t give me this crap about being to busy.

After searching for years on every forum and asking every body and fender person I came across now I know why my sandpaper gets clogged after a single pass on a repair. If it's just to keep air away could you use something like waxpaper on repairs to do the same thing? Have the same problem with Bondo / body putty. Must be the same issue.

hahaha well i just patched hole and i saw your method ok then i saw another and as you say it was opposite so i saw another and he started large worked down and covered it all with a large patch so i split the difference and did it the last way then covered it with fairing compound after sanding it will it work ? who knows .

I start with small patch as well. On boats it probably doesn’t make a big difference but when I did Abaris workshop, which is more aerospace oriented, I was told that small patch first approach, according to their tests, does much better in all applications that involve twisting loads. WEST people, for some reason, do it backwards. Last comment, I promise 😁

Hey Andy, great video as always! Wondering about fiberglass cloth from a slightly different perspective. When refurbishing a deck for instance and stripping down to the glass, where is the line between needing to replace the glass as opposed to simply being able to reapply primer and repaint? Clearly if the cloth had completely lifted or is bubbled you need to replace. But what about the case where you're seeing whiteness of the cloth but it's still (or seems to be) solidly attached? Thanks for all the great content - you provide a lot of inspiration and insight for DIY'rs!

Good luck with your shoulder Andy. Regarding curing does it matter how quick you put the gelcoat on to cure?

Thanks for the video! Did you end up selling the boat? I was wondering about the cutter you were using. I enjoyed the Q&A.

I use peel ply extensively in the current structural overhaul I am doing... granted, its just small Beach Cat. The two hulls are 17ft long, pretty narrow, and 99% of the glass work is done on the interior, so its really, really tight in there. I can't afford the time or the surgery to have cybernetic double joints to sand in impossible places... it saves me enormous amounts of time and frustration. I never go over the peel ply with additional resin, a wet hand lay-up is wet enough for the peel ply to soak through. I tried that method once on another repair job, which happened to be overhead (repairing core damage around a hatch, replaced the core from below because all the work is hidden by ceiling panels) and the extra resin I coated over the peel ply caused it to wrinkle and resin pools built up in the wrinkles. Anyway, the other added benefit besides the toothed surface and no amine blush is that the peel ply pull excess resin from the hand lay-up if weight is a concern. BTW, this all epoxy work, I don't use polyester resins in general but I would if the job called for it and that's why I love this channel!

Hello, your way of laying fiber for patching, is the way i would do it.. Can't see starting large to small. ill logical.. great for the info great shows you put on.

[@tigersharkzh]

I do neither small to large nor large to small. I number the patches smallest is 1 second is two etc. Laying up 8 layers I start at patch 1, then 3,5,7,2,4,6,8. That way only half my layers are in direct contact with the hull but each one has a greater area that it's bonding directly to the hull.

How does one go about using your consulting services? I have no problem becoming a patreon, but once I do that how does someone go about getting your specific recommendations for a specific solution? I bought a 45 ft sailboat that has almost everything new, but the engine compartment has the appearance of previous owners hacking up the walls and it looks like a butcher job. I could cover it up with panels but I would be bothered knowing what's underneath. I would like to rebuild the engine room walls and bulkheads so that it looks like it was made that way. If I were to send photos of the existing engine room walls and bulkheads, can you supply recommendations as to how you would rebuild the compartment if it were your boat? I don't need step-by-step instructions, but more of a high level design opinion. Your videos are fantastic.
