    I have a Polish mike with the same problem. I have not bothered trying to fix it. If I did, I’d make a replacement out of brass, maybe 2 pieces like an old Lufkin. My one Lufkin mike has a hub and...

    What can I believe about TPO? One roofer quoting on my house re-roof called it "TPO = Temporary Protection Only." On the other hand, it's popular, so hard for me to believe it's failing massively as...

    Here's another vote for a clutch problem. My F4 will sometimes fail to move in the Z up direction in normal feed, but moves fine in rapid. Sometimes it will move fine under normal feed and subsequent...

    I thought StressProof was the 1144 equivalent. I agree ETD150 is not the same as FatigueProof. I stand corrected.

    Best Material for Tailstock Spindle?

    I made a tail stock ram for my Monarch 10EE out of ETD-150 “Fatigue-Proof.” I had the body bore honed and then turned and lapped the ram to fit. I tried to bore the MT2 taper from first principles...

    How did you avoid the error when the magic smoke is allowed to escape? I am curious how you went about it.

    Maybe so, unless you luck onto a wiring diagram. No clues on the nameplate or a faded sticker inside the j-box lid? If it's currently wired 440 up to the switch, it seems like you should be able to...

    One solution would be to tape the rotary switch in the on position and hook the three VFD phases to the three wires feeding the switch. You can also use a continuity tester to suss out which...

    Nice to see you posting again. I look forward to more posts. I imagine there are all kinds of things that could be preventing the machine from starting up. Batteries, chips needing...

    Now I know 0.0002" TIR is fine for a 0.006" drill. I did three each 0.008" and three each 0.006". It's easy once you can see the drill and control the feed rate. I used a cheapie USB microscope to...

    I kind of stuck with the RPMs I've got, which is what limits the feed rate. If someone wants to donate an air spindle and the dry air supply to run it, I won't be mad.
  15. How much runout OK for a 0.006" cobalt micro-drill?

    The servos are tuned per the manual, which is probably aimed at ordinary milling. The job isn’t worth the science experiment that would be needed to figure out the optimum tuning for super-low feed...

    I watched the drilling through a cheapie USB microscope when I ran the 0.008" drill, and I could actually see the motion increments. Perhaps this has something to do with the fact that the machine...

    Yes, the runout is really nice. I was more surprised at how little runout the ER-16 toolholder taper had. The spindle taper on the horizontal spindle of my other Aciera is also almost undetectable...
  18. How much runout OK for a 0.006" cobalt micro-drill?

    I need to drill some 0.006" holes 0.004" deep in 360 brass. I set up in a 1-mm ER-16 collet and checked the runout. I got 0.001" TIR, which seems like way too much (analogous to 0.1" runout on a 5/8"...

    If the B&S are the slant-line style, try before you buy. I find it easier to mis-read the slant-lines compared to Mits. I prefer the Mits.

    Is it quiet like claimed? Gear noise is my main beef with most Euro mills. The only one of mine that is quiet is the FP2NC in horizontal mode. It’s quiet because the original owner never ran in...

    Yes, you need to get the ball runout as small as practical. If the ball is offset, then so is the location of zero. Setting and periodically checking the runout is the major use for my tenths...
