I think that depends on the results he's hoping to achieve --unlikely he'll get something that looks production-perfect, but he may come up with some very cool nonetheless...
Actually if you only work on the underside of the base plate, the homemade part doesn't necessarily have to show....
Okay, so you want to divebomb, eh?
In that case, how about a combo--you have your bigsby springs (because they're heavy duty) providing downward support...then you weld a three or four hooks into the bottom of the plate, and you attach Fender style springs to them...this way you'll get the best of both worlds....
I'm just assuming that since they're bass strings you'll need heavy duty springs to handle the stress.
You don't even need to weld-- you can also drill through the plate and bold something on....

Excellent suggestion. I was just trying to figure out which springs to pick out. I am already forming a mental picture.
Ma and Pop always told people that only their son would attempt such a thing... Heh
