Proxxon mods at work

I had suggested this mill and some of these mods to some hobby machinists but had never shown them at work. Well, here you go! One thing of note that's not evident in the video is a rework of the spindle to get it to run very true. Original runout was .005" to .008". With careful rework I got it down to .00015" / .00025". It can now drill very small holes reliably. Example: that is the accuracy that allowed me to drill a radial displaced 5 hole pattern at .006" diameter in the end of a .025" diameter wire, making a miniature valve handwheel for a model. That left only .002" spokes between the holes. Absolutely couldn't have even begun to get that part with a less precise spindle. It also makes every cut and finish that much better and aids tool life as well. Enjoy.
