So much wrong with this. Why not make it in one piece for starters? No gel coat, no multiple layers, no measuring out resin and catalyst, no roller to maximize fibre saturation. This is NOT how you build fibreglass boats. I've built dozens of glass fibre kayaks. You fair and polish the plug (here the original boat), take a mold off the wooden plug, then build the final kayak in the mold. The laminate needs to be built up in one continuous process to achieve a chemical bond. Using margarine as a release agent will contaminate the surface and lead to delamination of the subsequent layers. Use wax, and polish it.
Very nice! It did surprise me that you didn't use a scale to weigh the amount of epoxy and hardener. (The epoxy that is for sale where I live needs to be in the exact amount. Too much hardener and the epoxy becomes too brittle, too little hardener and it will remain sticky.)
2:57 I'm pretty sure that is not epoxy , but polyester, and MEK hardener. For lay-up work like this it's almost as good as epoxy, but epoxy cost double the price. The ratio hardener to resin is more important for the "open time" then for the strength of the finished product. Too much MEK hardener and you have only very short time to lay-up the fiberglass. Specially in the tropics.
That was Polyester Resin, I can smell it from here. I use epoxy for some things, and polyester for others. For a general purpose, knock-around boat, I'd use polyester every time. Far, FAR less expensive, and the weight difference on that project would only be a couple of kilos at most
Great video and build. Two things I would like to add for the next build: 1) Remove margarine (as I have for more than 20 years) from your kitchen and use it to make canoes. Use butter or any other natural ingredient to fry your food. Not Margarine, which does not have similarities with 'plastic'. 2) 3.57 / 8:04 When working with resin or cutting cured fiberglass, put a mask on. Preferably one with active coal. This shit is toxic in the long run, and you only have two lungs. Fiberglass will not be expunged from your body and remain there.
Three thoughts: 1) great work! 2) "plastic" is fine by me... remember that a generation of America's Cup finerglass boats were called "plastic fantastic". 3) I was hoping to see more time shaping the bow and stern... although this is mostly aesthetic, it would have taken the boat to another level. Guessing that sandpaper was out of scope...
If you take a piece of thick wire and bend it into a shape like a paint roller the put on the roller part two different size washers go large small large small etc… then bend the end of the roller to stop the washers from falling off but can roll ezy without much wiggle room then use it to roll the glass after wetting it thoroughly with resin the roller is better to get out air pockets and even out the resin saturation
very minimalist has glassfiber, rules have how long boat have etc, 4 meter need 4 level glassfiber to boat ewerywere. and this have minimi what need do, normal need 5-7 level glassfiber 4 meter long boat. then have normal strong boat. big boat etc, 30 feet sailboat need 1 inc glassfiber mean 30-40 level glassfiber all boat. or 20 levell under then honeycomp and then 10 level, save little glassfiber about 1/4
It is chopped strand mat (CSM), comes in various "weights" from 150-600g/m^2 and polyester resin and catalyst (1-2% depending on ambient temp). Needs to be measured!!! You should also finish with a layer of woven fibreglass roving (fabric). And you should use a hard ridged roller to saturate the fibres, not a soft brush to stipple. That way uses far more resin, and leads to far weaker fibres.
I got about half way through this before I felt sorry for people living in 3rd world countries and how they had to build things with inferior materials. Then, I realized, this is posted on RU-vid. This person has access to the entirety of human knowledge. Original boat leaked. Why not use polyester resin and fiberglass to seal the original boat?....No clicks, No views. Instead, lets use the original boat to make a new boat, without watching other videos on boat building. I admit, you got me with the clickbait. Good job. Hope you do well on RU-vid, but I won't be watching any more of your videos. You fooled me once...
