What's the most economical way to work with fiberglass?Would you apply it as a coating onto some kind of bulk material like a surf board, build it as a lattice, lay it in an epoxy?Let's talk about fiberglass
Another thing I can't work out is how much effort you'd put into mold it, vs how much effort you'd put into sanding and shaping it after its set.

>>2947474All the ways are cheap as dirt. There is no most economical because you're saving 10ths of pennies. And if you fuck up the forming you sand it and if you fuck up the sanding you form more etc.There are only two considerations 1. What are you making and B how much if a fucking mess can things get?
Well for example you can buy fiberglass as sheets, in rolls, and there are any number of types of weave.You can get fiberglass as fiber bats, or as threads.And when you set it, it's usually a two stage epoxy, but what ratio of resin to fiberglass is the most economical?And if it better to vacuum mold it, mold it under pressure, form it in the open. Do you do it layer by layer, or in one huge brick, or do you fiberglass layers then glue the layers together. I don't understand all the incel posts on 4chan these days, go back to pol Incels, some of us are building things.
>>2947749Resin and ply. Do whatever is the easiest until proven not working. Some people bulk up their resin with fibers and fillers, needless to say the dust is not good for the lung.
>>2947749>but what ratio of resin to fiberglass is the most economical?google it for me: 1.5 oz/sq ft of CSM needs about 3 oz of resin per square footin practice this means slather it on you're not going to weigh it out nor care in actual practice how much you need.>And if it better to vacuum mold it, mold it under pressure, form it in the open.well it fucking depends on what you're making doesn't it? obviously vacuum sealing is going to be more expensive because you need to buy the vacuum sealer big enough for the project and idk what the upside is when the benefits of fiberglass is forming it in place in the first place.>Do you do it layer by layer, or in one huge brick, or do you fiberglass layers then glue the layers together.as stated you form it, sand it, form more if needed, sand more if needed, form more if needed. it's like doing a plaster mask or those newspaper strips over a ballon. if you're talking a solid resin block you're fucking confused about using fiberglass. also you're fucking confused about using fiberglass in case that wasn't obvious. ditto "gluing" shit together, you're literally using resin what the fuck are you going to "glue" shit with? that's like making fiberglass pieces and then riveting them to other fibreglass, what the fuck would be the point?fucking idiot
>>2947782Good suggestion. Appreciated.>>2947973Benefit is typically a higher density and removal of air from the fiberglass.
I'm trying to repair an old lightweight fiberglass canoe that's got a small crack in it. Need to figure out what weight fiberglass cloth to use. I've got some random stuff that I think is like 9oz, it's far too coarse and heavy. I was thinking 4 oz, or maybe even 2 oz? Much harder to find though.Advice?The canoe itself is 14' long and should weigh around 35 lbs. It's nicely laid up fiberglass cloth, not chopped mat.
