No motor replacement for 152.217060 6 1/8 planer
You are correct, there is no replacement for part # OR90357, but if you have the original motor, I am sure that a local electric motor repair shop will be able to repair, or replace it. I'm confident that this is your best option at this point.
My Delta 23-197 variable speed grinder will not run. Only tried it once and it's been put up for a couple of years. Will not start. Light comes on. Has power
It's possible that the variable speed control may be the issue with your Delta 23-197 grinder. However, before attempting to bypass it, there are a few other things you can check.
First, make sure that the grinder is properly plugged in and that the power outlet is functioning correctly. Check the power cord and make sure that there are no cuts or breaks in the cord.
Next, check the switch and make sure that it is properly engaged. If the switch is faulty, it may need to be replaced.
You can also check the brushes on the motor to see if they are worn out or damaged. If the brushes are worn out, they will need to be replaced.
If none of these troubleshooting steps resolve the issue, it may be possible to bypass the variable speed control. However, this is not recommended unless you have experience with electrical wiring and understand the risks involved.
If you do decide to bypass the variable speed control, you will need to identify the wiring that controls the speed control and connect the wires together to bypass the control. However, keep in mind that this will result in the grinder running at full speed all the time and may shorten the life of the motor. It's always best to have a qualified electrician or technician perform any electrical modifications to your tools.
Price for used Grizzly G1550 metal lathe
depends on condition and what comes with it. generally starts at $500 in good shape and up to 850 if excellent with many extras (chucks, rests, knurling attach, faceplates, etc) Also, check for accuracy...

Have an old sears craftsman 1/4 hp grinder model
the two copper tabs under the on off switch are to break the power source.connect incoming power to one of these(black) then a short piece of wire from the other tab under switch to one of the three tabs under plate that is marked hot or l1 is probably #2 but you need to be sure. the white is the nuetral or l2 which is most likely #3 and the green is the ground most likely #4 I would definately look online for a wiring diagram to be sure if they are not marked with L1 L2 and GND
Older sears bench grinder wont run 1/3 hp model 397 19581
I know this is an old post, but maybe it will help others looking for information. I have the Craftsman 1/3-HP grinder models: 397.19580 & 397.19581. They are Split-Phase single voltage (115 V), and use a Klixon start-up current style relay - 2CR14-224. The relay is normally open. When the large starting current in the main/run winding circuit is sensed by the the relay coil (term 3 & 4) which is in series with the main winding, the relay contacts close (term 2 & 4). The one end of the start-up winding is connected to the main coil's BLK wire in the coil pack. When the relay contacts close the start-up winding is energized. The start-up coil is used to provide a boost to over-come the resting inertia of the rotor. Once the rotor reaches between 65% - 75% of operating speed, the current through the main winding circuit is reduced to the point that the relay coil cannot over come the return-springs force, acting on the relay contact arm. With the contacts open, the start-up winding is no longer energized. This should take about 2-3 seconds, if the relay malfunctions, the high current through the start-up windings (thin wires) may be damaged. Here is a diagram I have made.

I have a Buffalo Model B-8 bench grinder and am looking for a wire wheel attachment. This grinder was purchased in 1982. Not finding comparable parts anywhere.
A wire wheel is bought from the same sort of supplier as you would buy a grinding wheel.
The dimensions of the wire wheel should be similar to the grinding wheel it replaces, though the centre hole is usually larger and should be fitted and mounted with the correct size plastic bushes and steel retaining washers.
The guard and the tool rest should not be used with a wire wheel for safety and of course there should be a hook nearby to hang a pair of safety goggles...
Bear in mind, in a commercial environment, local legislation could exist that means only a suitably qualified and registered person is allowed to maintain/adjust a grinder as in the UK and Europe.
Un plugged the wires from the switch and do not
Mmmm... that's a little more complicated. If you have a continuity / resistance meter, we can noodle it out, though.
First, are the two white wires the ONLY wires coming from the motor? I suspect they are - that's not in conformance with any accepted color code, but it'll work. For the rest of this, I'll assume that the two white wires are the only ones from the motor.
You'll need to meter the switch itself, with no wires connected to it. In the OFF position, you shouldn't find continuity between any of the four switch contacts. In the ON position, you should find continuity between two pairs of contacts.
The black wire from the power cord should go to ONE of the two switch contacts in a pair that have continuity with the switch turned ON. One (either) of the white wires from the motor should go to the other switch contact IN THAT PAIR.
That leaves you with one more pair that has continuity with the switch turned ON. The white wire from the power cord goes to one of those, and the second white wire from the motor goes to the other one.
When you have it all wired up, plug it in & turn it on. If it's not right, it should immediately pop your circuit breaker. If it IS right, it should run fine.
If it pops your circuit breaker, open it back up and swap one wire from the power cord and one wire from the motor.
