I decided to build this filing machine as a machine project and I would have a useful tool when completed. Trying to file to line is difficult to do by hand. This machine makes short accurate work of that. After looking around trying to find one it was apparent nobody makes them anymore. I did find that Andy Lofquist at Metal Lathe Accessories sells a kit of castings with a nice set of drawings where one could be machined.
The motor and speed control are from Sherline Products, maker of miniature machine tools. This motor unit is used on their lathe and mill products and powers the filer very successfully.
I didn’t take pictures during the machining process because I found another guy that had documented the processes very completely if you would like to see what’s involved.
Below are a few pictures of the finished machine. If you would like to see it running go up to the top of the page and click Videos.
