So I have a hilt design that can be closely made by CSS parts but not quite:

Solution: machine my own hilt body parts from raw aluminum.
Problem: I've never made a saber so I have no idea what the required proportions are (i.e. blade width, battery pack width) or how to wire the electronics. Am I getting ahead of myself (I probably am)?
My idea: buy the cheapest possible stunt saber from saberforge and cut it open so I can see all the internal proportions and have a complete, prewired setup for the blade and switch. Build my hilt around those proportions and toss the electronics inside when I'm done.

Am I an idiot?
