After having little luck finding a good used one I have elected to built my own.I intend to use a right angle speed reducer for the base of the machine along with a ballbearing eccentric.My question is how fast do the commercial rigs run as far as strokes per minute?I want to make mine variable speed but don't know what to use as a base spm.

My old plain vanilla Oliver runs about 150 RPM.

Recently there was a plan for one in HSM or MW, not sure which as my back issues are out in the barn and I am not. I have been thinking about making one for my son-in-law to use in piano restorations.
Andy Lofquist of Metal Lathe Accessories has a die filing kit for sale.
In my experience, his kits are top quality.

I have machined one of Lofquist's die filers and it is a very smooth running machine. I am running it at about 400 RPM.

Not cheap,about $15 a copy. I've often wondered if you could make a clamp to grab the non-handle end of a conventional file and attach the clamp to the machine. Knock the tang off for safety.

The instructions that come with the Lofquist die filer include instructions for making your own from less expensive files. Easy and effective.
