Adjustable powder slides

[shell70634]

I have one screw adjustable bar and want more.  I have some that I make inserts for which is easy.  I have the time, a lathe, mill, all the tooling, but not the experience making something with such tight tolerances. Are there any drawings or old magazine articles out there that may help?  Any advice?

I see them occasionally on Ebay.  Did you ask Bruce Williams at StarMachineWorks.com?
Have not seen a dimensional drawing.
 
I have one the screw adjustable as well as one for the inserts. 
I find the adjustable great for load development. Once found what works, I either use a fixed bar or one with a matching insert.

Good luck.
