I used these guys 30 years ago. I think they are loosely associated with the S.B.A.

Andy,

Sorry but I think I'm going to go another way. The Mesa 7i33 Quad Analog servo interface looks like it'll do the job quite well. Combined with their 5i20 FPGA based PCI Anything I/O card...

Andy,

Tag me for:

It could be the motor starter capacitor(s) preventing starting in high speeds. I had a similar problem on my chinese lathe. Changed the capacitors and it's been runing fine ever since (5+ yrs).

Forget the mic-6 and think shims or scraping. (During final assembly of course)

The alignment of the shorter rails are not all that difficult. Belt or...you might want to think about a rack and pinion to drive it. You could put a rack on each side and one drive shaft to drive...

CNC thread grinding after brazing maybe? Indeed that is some tight work but the beauty of grinding is you can shape the wheel how you want it and it doesn't generate a whole bunch of preasure to...

This looks like a job of good old "hand straightening" after brazing. I did this for hundreds of hours many years ago. A pair of v-blocks and a dial (or digital) indicator to show location fo runout...

So Fyddler, what your really saying is that you don't see a build in the near future?! I just know that I had to put off my wife's "todo list" in order to do mine. And she was none to happy about it...

Know anybody that works for an auto body shop? They often have frame straightening equipment that will make short work of it.

A charge pump is a must when using a PC to operate a dangerous machine. I have had several occations where the charge pump saved my machine from self distruction. They are quite simple to install and...

I'm supplied by (www.use-enco.com) (best prices) or (www.McMaster.com) if your in more of a hurry. (www.mscdirect.com) is another equally as good as the others...Enco is just a little closer to me...

24 gage is pretty thin stuff. You might want to consider sandwiching it between some (sacrificial) plywood to hold it first. Use some double sided tape to keep it from sliding around (use sparingly...

I'm with Matt@RFR ... tell them what you said here. Most employers want someone how wants to learn. Too many people just want the paycheck. Take anything they offer...no matter how meanial you may...

...and I must say, Winona is a great place to live.

There is nothing wrong with the design. How did you come up with this G-code? nuplowboy had it right about doing a roughing operation first. You could probably get someone to run this through...

Patients is a virtue. Just think of it as "One cut at a time". Don't be afraid to ask questions here as you go along. There seem to be a lot of fellow DIYers that are more then happy to help out.

Keep us posted on ideas for the quill lock. Maybe someone else has already done something they'd like to share.

It's common that the machines are turned on early (sometimes hrs), sometimes left running over night, to let them come up to/stay at operating temp prior to beginning work.
