So what if you mess it up?
You're learning stuff.
I really messed this one up, 1/4" gap between the guard and the shoulder of the blade. All epoxied together and dried when I noticed it.
Nice job that mate, really nice.
Did a little research, stuck the handle in a pot of boiling water until the epoxy softened, took it off, cleaned up the tang and started over.
There's always a way out.
