I am not as yet, and the mill is still as shipped. This chapter is basically me, getting all my stuff in one sock. Today, since I am still crippled up, I may get the one coupling bore out to 14mm, but until those screws arrive, I can't assemble anything of note. I have a computer that I am going to see if a 5i25 card can rescue, when the card arrives, maybe yet this week. I originally set it up to do pandora in the garage, but it doesn't have the cajones to do that well, skipping and stuttering. Without a base thread, it should be able to run a mill. But its on a high shelf on the other side of the midden heap that is my garage. I'll have to move some stuff just to setup a small stepladder to get it down. And all this stuff will need sturdy shelving on the wall (the end of the house in fact) above & behind the mill. The isolation tranny has not arrived yet, thats 56 lbs crated & I've not piled all the motor psu stuff in one stack yet to see how big a box I'll need to build. Thats a monster toroid, and I'm of a mind to remove a few turns of the secondary as I expect 130 vdc is more than enough to smoke that 750 watt motor. As is, I'll have around 126 x 1.41=177 volts from a fullwave bridge & thats about 45 too much. Jon only rates the servo amp for 160v x 20 amps. The bugs are 400 volt or more bugs, so I suspect Jon is being conservative. The one running the lathe has only one part that heats, a filtering toroid whose wire needs to be a gauge heavier, the bugs stay dead cold. The lathe is doing great at about 108volts with the transformer I used there, extracted from a 1977 model of a Phase Linear dual 750 watt audio amp. Its spinning a 1 hp treadmill motor hard enough to break/burnup the plastic parts in the rest of that lathes puny drive system. This mill will give me the ability to make parts that it can't break or burn up (I hope) I have lots of preparatory work before I start pulling the mill apart as I want to have exersized all the motors laying on the table before I lay a wrench on the mill itself. Spindle encoder and such will wait till its made a few parts, or a blanket chest or 3. I have promised my boys a chest each (4 total) if I last long enough. The little mill carved all the joints for the first one, but was within 1/8" of its X limits to do it, plus I had to rig a support for the far end of the board because it was tipping the mill without it! Plus, we need to wreck another big UPS stepvan, the side panels make ideal boxes. I've about used up the last one from a decade back. But its made the electronics boxes for the small mill and the lathe, twice on the lathe as that bigger motor and its drivers are in a box off the back of it, the rest of the stepper driver & power is in another box partially made of brown epoxy coated 1/8". :) Getting 1/8" sheet cut and shipped to the middle of WV needs a bigger bank account, so we make do with found at the recyclers stuff.
