Turns out she had been playing games with the IRS, she didn't have that sort of money, so I was garnisheed for about 2 years.
As has been said, that was the screwing I got for the screwing I got. :( Still trying to conjure up an automatic tool catcher since I don't have the magic spell (or a vitamin supplement) that will grow at least 1 more arm. Them are as scarce as round tuits in these here parts. :( But I do have repeatable Z heights now, I have stop collars on the tools in use ATM. That has simplicated things a WHOLE bunch. > On 10/29/2015 11:42 AM, andy pugh wrote: > > If you make your own cylinder it actually all gets a bit simpler. > > http://www.cnczone.com/forums/vertical-mill-lathe-project-log/109301 > >-cnc.html (There is a link at the bottom to a video of it in action) > > Considering that I spend 99% of my time online, reading about CNC > conversions and watching machining videos, and only about 1% of my > time in the shop, it's a true tragedy that I didn't encounter your > solution to my power drawbar problem sooner.
