Do you know what spindle thread or other mount is on the PM, it doesn't say much on the page.
That's what I want to know also Gerrit, what's on the spindle nose

Spindle Mounting System is Direct Mount. Not sure what you all are asking.http://www.machinetoolonline.com/PM1030.htmlDepending on what you search for...if you find a PrecisionMathews site...it may be old. The one I saw was last updated 2010.Also, when I corresponded with Matt...he'd said something about a lathe coming that was the same as one he currently offers but would have cam lock.I assume features may change.
Zee........I saw your post from earlier about the PM1127 having camloc chuck. It doesn't indicate that on the spec sheet. I'm wondering if the next batch will have it. That would be nice. The PM-1228 LB has camloc. The only drawback of the camloc chuck is that it costs an additional $749.........ouch!
Yesterday I emailed Quality Machine Tools about the spindle nose on the PM1022V. He responded this morning saying that the lathe has a three hole flange on it and that chucks, or other attachments, have three studs.Why the heck the literature doesn't just say it's a flange mount, and maybe even give the BC and stud size, is beyond me.So there's the answer, folks. Very easy to find out.....Pete
Pictures do tell all! Thanks Jo. Just one question about that setup: Do the nuts need to be tightened/loosened with a wrench or does the ring have enough 'cam' to it?Pete
Let's talk flanges and nuts Zee If the Lathe designer has been using their noddle then what you have is a chuck which has three studs in the back on which go three nuts to hold the chuck in place. The holes in the flange will be big enough for the studs with their nuts to go through without having to take off the nuts every time. This is achieved by a simple disc that goes behind the flange which has three curved slots. This allows the studs and their nuts to go through, rotate the disc and tighten the nuts Each chuck has and keeps its own nuts.Cool idea! I'll have to check.If the designer is a cheap skate/does not really know what he is doing then there is no rotating disc and he expects you to get your fingers in behind the flange in that small gap to undo the nuts, remove them and position them in place back in place before doing them up again Sadly most Chinese lathe manufacturers do not employ designers with any noddle If you have big fingers you might need a camlock. You are very kind. I have fat fingers.
get the manual, if it doesn't contain this information in some detail then there is an indication of future 'fun'.
