Cast Bass Tuners
has anyone ever cast their own aluminium guitar tuners?
i build basses. all handmade right down to the pickups (pups by a friend) the only thing i rely on are the tuners which i buy from hipshot. i know of lost foam casting and sand, i actually worked in a foundry once for a week 
if anyone out there in yahoo land can start me off in the right direction or just tell me to keep buying them or whatever, i'd be very grateful. there are plenty of vids on you tube, but not really in the same level of detail that i'm after.
Presume you're thinking of making something akin to tuning forks?

Think you'd need another tuning fork to calibrate to and would needsome machining to tune the tunning folk to the correct pitch
Casting is unlikely to produce the correct pitches right on it's own. Apparently Russian bells are as cast, and there is the following.

Pitch pipes might be a lot easier to make using the physics from

Best of luck.
