OK, OP here. There have been some good thoughts on my efforts to get some epoxy through an 8 gauge needle. It seems like the options are...
1) find some lower viscosity structural epoxy.
2) use laminating epoxy.
3) use laminating epoxy with additives (but wouldnt this thicken it?)
4) heat the epoxy carefully.
5) add denatured alcohol to. the epoxy (but this weakens it)
6) ditch the needle and use a
dowel to apply the epoxy.
(I'm not always happy with
this method, I find this to be messy and I dont always get the internal
fillets as even as I
would like.
Which one is strongest do you think?
And thank you to all who posted.
I wouldn’t be concerned with the aesthetics of internal fillets. It’s very difficult to make them look neat. I simply go for strength and don’t really care what they look like. No one’s gonna see him after the rear center ring goes on anyway
