To tack the frame together I went through about 1 1/2 tubes of scotch weld.

I'm using that ^^^ size tube, I'm using the 125 type (25 min working life as apposed to 90 min of the 190 above).

For the epoxy I'm using with my hemp fiber I have a 2 quart jars of epoxy and both come with small cans of hardener. It's made by West Systems. I expect one quart is going to be well more than plenty.

{edit}
Aircraft Spruce sells the epoxy, mixing tips, and handle (like a small caulk gun) separately and they are not all on the same page. They also sell the tips in groups of 1. Make sure you get a handful of tips, best to call when you order.
