2018-12-25Rebuilding and Upgrading a Jet JMD-20VS Mill-Drill Part 1 Many years ago my first mill was this Jet JMD-20VS-1 variable-speed mill-drill. It was adequate and I made a great deal of parts and mods with it but within a relatively short time- three or four years at best- I had pretty much worn it out
