Thanks so much for the very detailed breakdown. Other videos in this series are terrific. What are a few tips you would recommend if I would like to apply two layers of cloth in one go ? Is that recommended ? Thanks -
Very very nice , how many layers of gelcoat should be used and how many layers of fiberglass should be used to achieve the right thicknessy ?. And what should be the sufficient thickness of the body for this boat or for an even bigger boat? ..
Great video sir but I had a job hearing you right because of the acoustics. I make professional films, if you throw some foam or old drapes etc around your garage or hang some from the roof it will deaden the echo - hope this helps. Your video has helped me glass my sea cruiser!
Concour on laying glass first. Also I use low visc epoxy and slow hardener. Something of that size takes two people wetting out and one person making up small batches as you need them. Temperature effects how well and fast the glass absorbs and I generally try for low 70's. . Too warm and the epoxy sets up to fast and to low and it's difficult for the glass to absorb in a timely matter. Your under the clock glassing and you have to keep moving. Also after it's absorbed you want to remove the excess with a scraper (called a bondo scaper) otherwise you can get runs. Also use a heat gun to release trapped air bubbles. There's a lot more to it then your video.
Be EXTREMELY careful with non marine products. Some products have incompatible curing agents or solvents or will fail if exposed to water. In our experience bondo is one of the products that does not hold up well over time. We recommend using a marine fairing putty or marine glazing putty.
Hello, I am thinking to have a small sauna in the after cabin of my glass fiber sailboat? May this project go well if I investering in a proper isolation? Or is that just an insane idea?
I know this video is over 3year but still hope you can reply and give me some help...how long do I have until the epoxy resin catalysis begins and would be too late to correct the fiber glass adjustments...I keep worrying that my t iime frame is short and so my boat building is on standby...I have the whole body done and ready for fiber glassing but unless I know the actual time limit, I fear to finish it. Nice video but the elapsed time is so hard to judge...hope to hear from you.
Hi Im Israfil from Bangladesh. Nice .but what you do mix for glue please say that details. make the glue product name, please please please.......................
I am not sure, but I think it is so that the fiberglass will stick to the wood. Essentially, the epoxy is gluing the fiberglass onto the wood. The epoxy was still wet when the fiberglass cloth was laid on top. If you let the epoxy dry before putting the fiberglass on, then I don't think that the epoxy would do much.
A plywood hull with epoxy is very different than a vinyl-ester or polyester hull with plywood used in it. Marine plywood and epoxy boat building is used by some of the most prestigious custom sport fish builders, and when done correct will outlast and outperform other materials. However, most folks are familiar with rotten transom, decks, or stringers in boats with some age. Over 90% of those boats came from a mold and use an 'ester resin, which is not an adhesive (like epoxy) and thus makes a superficial bond with the wood.The problem is that the glass and wood de-laminate over time as the the hull flexes and moves, hairlines cracks in the glass are created and let water in. Coincidentally, these cost cutting manufacturers often use non marine grade plywood and drill holes and screw things into the wood without sealing the exposed wood. This is a recipe for disaster, but they built and sold the boat as cheap as possible... I have no respect for that.
At this time, we don't have any plans for composite. But to answer your question, yes you could use the same concept. However, you may have some challenges keeping the composite core from deflecting while you build because it is more flexible.
You can use many brands. Just make sure its EPOXY and not polyester. You will know its EPOXY when its $100 per gallon... ;) Several brands are West Marine, System 3, or Glen L.
Your woodworking skills are good. However you would benefit from learning how to laminate by watching a surfboard laminator. They laminate many boards a day professionally. There are many ways to 'skin a cat' but this way, the way you have applied the cloth is just made the job more difficult. You should run the width of the roll down one side of the bottom of the hull lapping the centreline and over the chine by at least 2 or 3 inches or more depending on the width of your cloth and the bottom half of your dingy. Repeat for the other side. It's not necessary to coat the ply wood first, just lay your cloth down and wet out over it with a roller or squeegy or with just a squeegy. If you use a roller on the sides, go over it with a squeegy to get the cloth pressed down onto the ply as resin 'floats' on a resin rich application. You don't have to take the cloth off and make a difficulty of placing it back on a wet surface. In life, we are always learning. Cheers
what kind of epoxy resin can be bought in such large quantities? ... it seems like in my country there are no epoxy resin sellers in large packages. Can you tell me, the brand and series of epoxy resin products? ...
Where are you from? I also noticed that epoxy resin in bigger quantities specially marine epoxy is not so available in the Philippines. Polyester resin though are more available.
go on the "west systems" website. I bet they can sell you as much epoxy as you can afford. And if you can use cheaper stuff "Alibaba" will ship you a container full.
Sorry, I missed your question. Yes, epoxy is the type of resin. Many brands and vendors are available. However, not all epoxies are the same. Be sure it is formulated for use in wood joinery and marine applications.
@The Mystic Ruler The epoxy later in the video has an additive mixed in known as "fairing filler". It makes it easier to sand prior to applying primer.
Typically you only need one layer of fiber glass. He also did one layer on the inside. The seams of the wood like the keel and where the sides meet could get two layers of 3-4" wide fiber glass tape if you wanted to go over kill.
@@FixNewsPlease i was a fiberglass tec and it is used all the time . fiberglass is also not waterproof and will soak up water and become very heavy.polyfila used in fiberglas is made for it and is green in color its not the crap used on cars
Sorry there has not been a satisfying and educational video For a perfect video you must start from scratch.Shure so too many more I am sure you will get much more likes.Greetings from turkey
Why only one layer of glass? There is no way that would be strong or safe enough. Should have been at least three layers, otherwise that ply will get wet and the whole thing will be useless.
The main structural support is in the wood hull, the glass is to seal the wood and provide abrasion resistance. There are countless boats built with this method and no issues for many years. The use of epoxy resin which saturates the wood (unlike poly or vinyl ester) marine grade plywood make a very strong, safe and reliable hull.
@@arthurtaddei1285 the 'ester resins do not bond to plywood well at all, they have minimal adhesive qualities. They will delaminate, period. Cure time varies with hardener, temperature and application. You get what you pay for...
@@saltboatworks1139 Used polyester all my life and never a problem unless going over epoxy . Been in fiberglass repair and outboard business 35 yrs and was taught the correct way .Epoxy Sucks
