From what I've read you can program the VFD to show within 1% actual spindle speeds. Applicable to many other machine types are LED digital tachometers with a "Hall type" magnetic proximity sensor. $10-$15 EB/AMZN. Glue a small rare earth magnet near the shaft of pulley or drive shaft and it...

Thanks for the recommendation. That looks to be an explosion proof non ventilated motor - This seems exotic (read finicky), but I haven't researched this class before; also, I've never run one before. F class insulation is nice, but I imagine thermal issues are perhaps more common with this...

Thanks for the replies guys. I've been doing a little digging with your comments in mind. The tapped holes on my motor plate are 3" OC Vertically, and 5" OC Horizontally. Using NEMA Electric Motor Frame Reference Chart - This would make my dimensions closest to: 'E' at 2-7/16" and '2F' at 3" -...

Test

Looking at the parts diagram for the Powermatic 1150 drill press. I have 3 questions for anyone who might know/care to chime in. 1) My machine was missing part '15-537 (Lock Ring, Spring Cover)' It looks to be an internal split ring, but I need the OD/ID spec to order online. Does anyone...

I should have known better than to try photos so soon. They are all screwed up above now. Probably my new member post count is too low. Thanks to American Locomotive for the quote to try and get the photos up. Thank you also for the responses. On the parts: I didn't think this wear was...

After a complete tear down and quick grease cleanup I decided to take a couple photos of the obvious damage of the machined parts on the drill press I bought. Before I go off and throw money at a bad machine I wanted to get a second opinion. From what you see here, are these components in...

I saw a thread a from a couple years ago citing Scott @ Redmond Machinery as the go to for old Powermatic parts. I read Redmond bought out the supply house when they sold out to move to overseas warehousing/production....? Anyways - I've tried email with no reply, and the phone keeps ringing...

I have seen that this is a widely available device type; however there are quite a few vendors for 120V 1ph IN & 220/440V 3ph OUT. Since 3ph motors are generally cheaper and much more available that 1ph, I was wondering as well if there was a VFD spec type that is generally cheaper? Digging...

I've chanced upon and purchased a reasonably priced Powermatic 1150 drill press rebuild project. Serial number (2-S820) dates it to a 1962 I believe. It is a 1/2 HP 3ph, 5 speed step pulley, tilt table, bench-top, rounded pulley shroud version. Though it ran just fine when I demoed before...
