YES! This did the trick. First time, ran backwards. Switching 5 and 8 did the trick. Runs very nicely. Had all the kids out there taking turns sanding scraps for maybe 20 minutes on a 15 amp breaker. I guessed also that previously the start and run windings were fighting each other. Thanks all...

I don't have 230V available but could add one into the breaker box. I just found a picture of a sander that looks identical including the motor, my motor plate just isn't there any more, says its 1 HP 13.6/6.8 Amps 115V/230V. That image in the book is great, thanks for passing it along. I...

Just by sound I don't think it ever got up to full speed. To get it to spin forwards I had to swap the hot and neutral on the power cord; the T5-T8 swap did nothing. A few more measurements after removing the start capacitor; T5 goes into and out of the start capacitor...

Thanks for the thoughts guys, will look into it. A couple more clues; 1. No burning smells. 2. I hear a click from the motor when it stops.

We have signs of life at 110V! Had continuity across T1/T2, and across T3/T4. But across T5/T8 there was only continuity one direction (swapping meter leads) - maybe this is expected. Wired it up with T2, T3, and T8 to black and T1, T4, T5 to white. Spun backwards and tripped the 15A breaker...

Ok, so hook up a cord carefully, plug into power strip and see what happens? I see these things hooked up to complicated looking switch boxes and thermal overload protection - what's really necessary on this thing once I get it spinning at all? The start capacitor has a cover, just wasn't...

Hi guys! I just got this Rockwell Delta 12" disc sander for $21 at an auction. Now, not sure what power it needs as there's no motor info plate on this one. The start capacitor says 115V. There's 6 wires sticking out into the box. There were two loose wire nuts in there. Three wires were...

Looks good to me! How big?

Go for it. Keep us posted, that thing's sweet. Large tables are a very good thing. I only have 4 DPs in a 14'x16' shop, plus a post drill out back. Guess I have a ways to go. Nice to keep them set up for different tasks.

Sounds like you got yours a new spindle. I recently got an old Jet 13-R benchtop DP for $50 knowing the "spindle was bent." Also needed a start capacitor, easy. The taper - chuck interface was all trashed like yours but it didn't look bent. So I stuck that old spindle in my even older lathe...

Interesting. Same style as Boker who I think was originally German, with probable German name (Einstein) stamped in English. Maybe old Albert made this in his garage... The legs on mine are a bit thinner than the Bokers...

Is that directory of american tools and machinery patents? I could be misspelling something as well.

Here's an old outside spring caliper to identify the maker. All my others have two separate legs, a pivot pin, and a spring. This one is one forged piece plus the screw and nut. Pretty cool. This one I suppose the spring is a little bit tweaked since I can't close it under about 1/2" and can't...

There's plenty of adjustment in the motor mount, you can probably pick up a 1/2" x 36" belt locally for about $10 if the extra 1/2" is giving you trouble.

Looks like its just getting broken in. Other than that I can't help much.

Curious if it was made as a v block for machinist workholding as I don't see anywhere to clamp it down (without a vise), or a bottom die for a press brake of some sort?

Harbor freight has a foot pedal switch for $17 https://www.harborfreight.com/power-maintained-foot-switch-57200.html

Oh man, I could use that. And the bit collection looks pretty good too.

Here's an old Nicholson file I got a while back, probably $1, looks unused. The cross section is shaped more or less like a knife, but the grind looks "factory" that is, I don't think its someone's half finished project. ALL faces and edges are smooth (no file teeth) except on the wide side...

Here's my 6" modern Palmgren in action. At work we had 16 downlegs for a roof (not your ordinary structure). Each is about 8 ft long, 1.5" sch 40 pipe (1.9" OD). At each end there's an angled notch, with a short bit of the same pipe welded in there. The angles at each end vary, and there's also...
