Could you please share the link to the PDF manual?
Thanks so much-
EDIT: I believe I found it: http://www.siegind.com/product.php?id=21
Back on the tapers, parts available from LMS and this about unimat 3:
"The headstock spindle was bored through a generous 0.4" (10.2 mm) and carried a nose thread of M14 (similar to DIN 800)"
"The tailstock barrel had a travel of 0.9" (23 mm), but did not have a taper - instead it carried a replica of the headstock spindle thread."

Head and tail have M14x1 threaded mounting on the outside diameter. the hold through the spinal is 10 MM and the tailstock is that same, possibly with some means to secure what would normally be the tapered end of a live center (roller center by the old book).
Thin cross-section of the spindle nose.... 10mm thru hole, 14mm od = 2mm cross-section, -1mm thread depth = 1mm (give or take) of spindle nose cross-section.
Should be plenty strong for it's intended use, but I wouldn't beat on the chuck with a hammer!
Being that I desperately need something bigger and not smaller, and don't really have $100 to just blow.
When do I feel such a need to order one? I think it would look good setting on the coffee table.
It probably won't be there for long, 374. Better go lift a wallet or play some poker and get $100
So, I guess a CNC'd version is "factory and available... somewhere. Perhaps someone will find a way to order the factory parts. Looks like the lead screw is driven by a shaft under it going back to the main motor.
I also ran across the Sieg pic last night when I was doing some poking around. Impressive they took a closeup shot of it with rust on the ways.
They did do a very impressive job on the belt guards, looks really professional. I'm not terribly fond of conversions where the motors are sticking straight out from the leadscrews. This thing must use one heck of a tiny Y axis motor! For such a small conversion, it's an extremely professional looking conversion.
clytle374, the price is very motivating to order one. When I saw it for that price, I didn't even pause before ordering it.
BTW: got my shipping confirmation email today!
Wow, fast response!
They sent the parts list and drawing for their CNC version.Originally Posted by SIEG Industrial Group
