Good luck, Scott.

There may also be connection information printed or stamped on the motor nameplate.

You got a point there. Did not touch motor wiring.

Recall when I bought the jointer from a used tool machine reseller. Got it cheap and said to me something wrong with "electrical". Now, meaning the "motor" run opposite direction?

Grainger is more than 45 miles from my place in the Central Valley, CA and not many electrical shops where I live.

Before driving anywhere, how to test capacitor and may incorrectly connect wiring from motor to start switch and out to power?

Would still like to have pictures or diagram of "Rockwell" start switch.

I have seen a bad capacitor cause the motor to not start or spin slowly in reverse. Does your's run slowly in reverse or start and run normally, but in reverse? Some multi-meters can measure capacitance. A capacitor analyzer can measure capacitance and leakage. If the start winding and one of the run windings is swapped the motor will run in reverse. You will need a connection diagram for the motor windings if a start and run winding are swapped.

Of making the motor run backward??

No, it's not.

Oh, really? Where?

-------------------------------------------------------------- As others have mentioned, the motor leads are incorrectly connected to the 240VAC source.

The T5 and T8 leads are the problem.

The motor nameplate will have connection diagrams for 120V and 240V power as well as CW or CCW rotation.

You also may find the connection diagrams inside the motor junction box.

Have fun.

BTW, patience is a virtue when dealing with all things electrical.

Assuming this is single phase.

If you cannot locate a wiring diagram for your specific motor, try this: remove the connection cover and take a look at the wires inside. Your motor will have a "start" winding and a "run winding." Reversible motors are tradionally reversed by swapping the connection to the start winding. (Electrically speaking, swapping connections to the run winding would also work, but often one of the run winding connections is not accessible.) Usually the run windings, will be a larger size than the start windings. If you see a couple terminals or wire nuts connecting to these smaller windings, swapping them will reverse the motor direction.

I know this may be daunting for someone with no electrical experience, so you may want to have someone more knowledgable check it or do some research on in the web and check some pictures. Should be pretty easy to find examples in google images.

Three phase 220 is very common in the US. I have a 5HP three phase motor out in my garage right now that can be connected 220 or 440.

Nice talking to ya,

Scott.

dpb, Took the motor out from jointer to see better. The motor is reversible - CCW and CW (very small print). Follow instruct from nameplate. Interchange T5 with T8 lead for CW rotation.

Thanks dpb, didn't spend a cents, more than happy to buy you a case of beer, I'm a Teetotaler. :-)

Well, kewl! I don't know when the T1-T8 numbering came into vogue; I've an old Walker-Turner shaper of unknown exact vintage but at the time of the original Delta merger as it has a combination of pieces-parts casting numbers--the fence casting is, in fact, identical to the one on the small Delta 1/2" shaper of some 25-30 yr later that has a different numbering/identification on it which was my initial hesitance...

Well, "whenever" is good enough--we'll meet wherever you suggest? :)

[side job scooter]

Excellent! Glad you got it fixed. dpb take a bow.

Scott.

[WD]

Just tested it and purrrrr like a kitten. Excellent!!

Do you mind hanging around a bit longer?

Presently rebuilding a 1941 Craftsman bench DP model 101.03662, by Atlas. Broke the spindle?s pulley, while rebuilding it. Unable to find a replacement pulley. Last resort drove over 50 miles to a machine shop for machined "stub" replacing broken piece on the pulley. The "stub" bore 5/8" and two keyway (instead of 9 spines bore) for spindle shaft slides up and down. It's still not ready. If everything turns out as planned, will silver braze stub replacing broken piece and two 1/4" keyways.

To view (almost) an exact pulley see Ebay below and identical drill press. However, Ebay seller did not replied bore sizes and did not buy. Do you know where to buy a replacement pulley? Original is better than the silver brazed "stub".

Presently using a 1940 Turner Walker 15" bench drill press and will replace with Craftsman (Atlas) DP. Like Atlas more than Turner Walker. This is my 4th vintage DP sold my vintage Atlas before we walked out from the house and loss everything.

1942 Atlas Drill press.

Wherever in Central Valley is about 120 miles from SFO? Thanks and warmest regards

Yes, he deserve more than a bow. Anyone including you willing to help or contribute however small deserve a bow.

Thank you :-)

Told ya it wasn't the starting capacitor...

[side job scooter]

Good call! Take a bow. You have a right to be proud.

Take care,

Scott.

I don't know of any other sources other than to keep looking, sorry. I'd suggest contacting the eBay person again if it looks reasonably close that you should be able to get a decent idea on bore by referencing the OD on your monitor to the bore and splines with a ruler. Should be able to tell whether it's worth pursuing or be able to reject it if it's drastically off.

Been almost 25 yr since been to the area -- used to make trip to Palo Alto to EPRI offices regularly back when was still consulting and have a cousin in Menlo Park, maybe a trip is in order??? :)

Glad to have been able to help on the motor terminals...

Are you aware of the vintagemachinery web site?

There's info there on old stuff and occasionally one may find another of your beasties you're currently working on and there's also a buy/sell link as well as discussion/looking for area.
