« on: July 19, 2019, 11:56:52 PM »
How popular is the 8520 and 8530 mills out in the wild?

Curious....

I had a Clausing 8520 with a Bridgeport M head on it. A Clausport 8520M!  That was four mills ago. Iíve been spoiled by Deckel and Aciera since, but the Clausport was a fine home shop mill. The 8520 part was like new, having only ever been used as an optical stage. $125 was the price!

What parts would you improve?

That is a tough question. The overall rigidity could have been better, I suppose. The ways were decently machined but not scraped. Fit and finish were useable, but certainly not up to Aciera standards. No power feeds anywhere. I realize each of my Aciera mills originally cost about 10X the cost of a Clausing.

I have an 8530 with 3 axis Shooting Star DRO and a Servo Drive, also equipped with a  3ph motor and VFD.  Equipped it with a an ETYM ER25 collet system.  Replaced the quill lock bolt with a handle.  It is a real nice machine.  It could be more rigid but if you use it for what it was designed for it does a fine job. At this point for my small models I use it for about 80% of the work.  I am fortunate to have a Bridgeport to use for heavy stuff.

I just added a 8540 Horizontal mill with a Bridgeport M Head adaptor.   The M Head was new out of the box with the B3 (aka mini R8) collets.  Have just started using it.  The Adaptor plate was advertised in HSM a bit ago.  I like it because I can use the horizontal features with out removing the M Head.

Dave, there are set screws to set drag on the quill.  Mine wouldn't stay up at all when I got it.  The set screws helped; but I also evenly torqued the bolts above and below the quill lock.  I torqued them to 40 inch/lbs.

Well, that's good that they provided some mechanism to keep the quill up, but a set screw and friction is pretty marginal.   It needs a spring.    hmmm
