Funny you should say that the other project is an Axis...
My headstocks never make sense until the guitar is done. Even then some people hate them.
Yes I am shooting for very light weight but still balanced. The limba neck is really light and it is allowing me to do some things I can't usually get away with. We will see when I am building a maple neck...
One thing that has made the guitars inconsistent in the final weight are the exotic tops. Bloodwood, Ziricote, Maple, Soft Maple, etc... all have very different weights. It feels weird picking up a guitar so thin that is normal guitar weight. So I want them to be consistently light. Chambering is the answer. I plan to chart all the weights next year to create a matrix of how much chambering for the different tops/backs.
I am going to put the P90 in a nickel humbucker cover. However they are not done yet so I used dumby pickups.
I don't have any sound clips because my customers are lazy. They promise sound clips but never send them to me... I guess if you want something done...
See what Bob123 said.
I modified a socket by thinning the sides and grinding the face flat. Then polished the crap out of it... I will post some pictures of how to make one without a lathe when I get some time.
The washer and nut must be a differn size on yours then. On the hipshot tuners i used, the nut and washer have the exact same diameter, so there is no way you are getting anything between the nut and the hole they are recessed into. The needle nose pliars are the only thing i found to work, but even with extreme care they still scuff up black finishes.
