Thanks guys!

Nathan, I've got a Clausing 8530 mill. It's a pretty nice little machine. Only thing I wish was different about it is it would be nice to have more Y-axis, but other than that it's been able to do what I've wanted it to do.

A little progress over the weekend was the center bearing/slip ring mount or whatever you want to call it. There will be a hollow "pin" that will poke down through the machinery deck and into the bearing and keep everything centered. At least that's the plan, assuming my machining skills are up to it. We shall see. The other unknown is if this little slip ring is up to running mini-servos for the tracks. If it gets fried I might have to build one.

I was worried about my slip ring on my drag so I put one in that will handle 10 amp per circuit. Now I know my current draw for the whole machine while under a load: (1.5 amp @90VDC)
I could replace it with another twin that I have that has more circuits. With more circuits I can eliminate my radio all together and hard wire the machine to my master switches from the 1:1 machine.

My slip ring had a sticker on it that said "2 amps" but didn't say anything about at what voltage. I got it off ebay from someone catering to the home windmill power generation folks, whatever voltage windmills put out. If it doesn't work I have a bit of room to replace it with something bigger.

Latest progress is the swing circle. All that's left on it is to get the shaper running and cut gear teeth.





I was very happy with how everything bolted together. The swing circle locates the slip ring mount and both bolt to the carbody and it worked! Rotary tables are neat.



I decided to get started on track rollers. Had time for two tonight.
