Weldon 40 for complete build

[lifeon2]

Hey guys I'm new here and I have been reading through for most of the day. I'm not sure if I just missed it but I was wondering if any of the tank builders on here has opinions on building a 96x30x18 tank using weld on 40 instead of 4? I know its more expensive but thats not really a concern. Anyhow thanks in advance.

FWIW I only use #40. It's a lot more work using weldon 40 but the strength of the bond is a lot higher also. I'd recommend doing some test glue ups first if you haven't messed with it as it handles differently than weldon 3 or 4. For one a small gap is needed for the glue to flow into and there's a failry short pot life. Since it's roughly the viscosity of 90 weight oil If needed weldon 3061 can be used to thin it. Here's a 300 recurve tank I built last year using #40:

That's an impressive tank. Who bent your acrylic? Or did you? That's oven work. BTW isn't 40 a two part reactive solvent? Sounds like a lot of prep work.

Thank you! I have my own oven.

Sweet tank man and I will take your advice on playing with it first, I ordered a gallon so I have a little extra

Thank you!

Weldon (scigrip) has material usage sheets somewhere on their website. I use cheap "applicator" bottles frim beuty supply stores to help apply the mixed glue.
