Hi ,
What is a good way of glueing plywood bulkheads to plywood sheet ?
I'm thinking epoxy , but do I have to fuel-proof the glue joints ?
Question 2 ...
What is a good fuel-proofer for the engine compartment ?
Thanks in advance

Rob: Epoxy is the way to go on both. When fuel proofing the engine and tank compartment with epoxy heat it so it will flow and get in all the cracks etc. and is easier to spread.

I agree with Lee! Epoxy for my plywood gluing.
Get some *acid* brushes to apply epoxy to the tank/engine compartment. A hair dryer or heat gun on low and spread it around. It doesn't take much.

Hello
Best thing is to use "SLOW CURE" epoxy , 1 hr to 3 hour handle time with 24 hour setup is best for the bonding your wanting to do. The epoxy has much more time to soak in and get a bite on the plywood, and when you heat most any epoxy it will rapidly accelerate teh dry time, slow cure gives you more time to work with it

My reference to "heating" the epoxy was only for spreading it around the tank/engine compartment. I do not heat the epoxy when I am actually gluing any parts together. I like for the epoxy to take it's time curing in that situation so that a maximum bond is achieved! y1 ;D

Hi Bill
Right you are , Nothing wrong with heating epoxy, I routinely do it, but that is why I recomend slow cure, still gives time to soak in and good working time, if you heat fast cure, it can get thick before you can even get it in place. Plus if you heat the slow cure as you know , it is much easier to spead around for fuel proofing, and also it help the glue to soak in better when you want a good joint.
Great for pipe tunnels , you can fuel proof the tunnel with just a little glue , although when I do fuel proofing i normally paint dope over the wood first to stop the raw balsa from soaking up epoxy. That way you don't have much weight gain
Another use for heated epoxy is when you are sheeting foam components, the slow hot epoxy is much easier to spead around and scape off, so you get a better bond with less glue
