I decided to make some fins out of foam board after hearing what everyone had to say about it on a previous post I did. Also because I needed to add so much nose weight to the front of the rocket to make it stable, the foam is much lighter requiring much less nose weight.
And, the balsa fins I had cut and was prepping warped way beyond use, even after laminating them with poster board card stock.
So I am adding a balsa strip to the 3 sides of the fins (not root edge) and I'm running low on epoxy. So I hit the shop and found some Gorilla Glue.
Anyone think that this may be a bad choice?
Don't see what difference it would make, just open cell foam board with paper backings. And on a previous email AK models said they use Gorilla Glue for their glue ups.
And, has anyone used Gorilla Glue for anything on their builds?
I know it foams up and expands, which causes another problem since you can't really clamp the foam board without denting the heck out of. But it does sand a whole lot easier than epoxy.
I still plan on using epoxy to mate the fins to the paper body tube and for the fillets.
Have a great weekend everyone!
