Join me in the machine shop for the completion of the surface gauge project. In the last video we finished only 2 out of the total 21 parts. Almost all of the remaining 19 parts will be made on the manual lathe, but first it needs an electrical upgrade. I’ll be swapping the phase converter for a VFD to get true 3 phase power. But not without learning a few important lessons along the way. Each of the remaining parts presented their own set of challenges that required the use of some new tools and techniques to complete. Including custom form tools and using a follower rest on the metal lathe, On the vertical milling machine l also get into using the collet blocks, slitting saw, and the rotary table. With everything assembled I test out the surface gauge as a squareness comparator using my favorite Mitutoyo tenths dial test indicator.
