I would like to reverse the rotation of a 60-042 delta TEFC 1 1/2 hp motor. any suggestions? Need CW rotation for a table saw

Yes, it is possible to reverse the rotation of the LR63420 Model D motor from CW (clockwise) to CCW (counterclockwise). Here's how to do it:

1. Turn off the power supply to the motor.
2. Remove the motor cover to access the motor terminals.
3. Identify the two wires connected to the start winding of the motor. These wires are usually marked with the letter "S".
4. Swap the positions of these two wires. For example, if wire A is connected to terminal 1 and wire B is connected to terminal 2, then disconnect wire A from terminal 1 and connect it to terminal 2. Then disconnect wire B from terminal 2 and connect it to terminal 1.
5. Reinstall the motor cover.
6. Turn on the power supply and test the motor to see if it is now spinning in the desired CCW direction. If not, repeat steps 3-5, making sure to swap the correct wires.

Note: Reversing the rotation of a motor may affect its performance and should only be attempted if you are experienced with electrical wiring and motor repair.

Unless the motor was replaced it should not require reversal.

To reverse the motor you need to swap either the start windings or run windings. See motor name plate.

Check vintagemachinery's website. You might be able to find some information there about your saw. Or make a quick google search , several threads will show up upon search that could help you. If you need band saw blades, I suggest you to visit sawblade.com .

Simple solution: switch two of the wires. Doing so will reverse the direction of the motor. You can switch it at the motor or on the electrical plug end.

you can reverse the rotation CCW to CW if you reverse the wiring on the brushes

You may have lost power on one of the wires to the motor. Check the wiring for breaks, if you have a meter make sure there is power to the 2 110 volt wires.

Exploded diagram for your SM100M miter saw is here.
User manual is here.

Page 20 covers blade change operation.

Make sure you unplug your saw! You need to remove a screw from the cover and rotate the cover to the rear. Use a hex wrench in the motor shaft to keep the saw blade from turning, and loosen the arbor nut with a 1/2" wrench. The arbor is reverse threaded, so you'll turn it clockwise to loosen, then counterclockwise to tighten it up after you have swapped the blade.
Rotate the cover back after that's done, and replace the screw.

My 10" Craftsman saw started life with a 1 hp motor. I'm on number 3 motor which is 1 1/2 or 2 hp. 1 hp seems to weak. The pulley diameter is about 2". The motor needs to rotate as the blade is moved from vertical. Mine is mounted to back of the blade arbor. The mounts needs to be adjustable for adjusting tension to the belt. McMaster Carr would have the start of a motor and base.

Could be a couple problems, first the brake is it electronic or work off the field in which case the brushes could be worn or dirty and possibly the commutator needs cleaned. The startup is another issue and could be a bearing that is seizing up or has a race collapsed. I would recommend going to Dewaltservicenet.com and typing in your model number to look at a schematic on this tool before going further. Let me know.

you need to grab the blade with something.maybe some pliers(if you are not going to refurbish blade) and loosen the nut in the center of the blade. i think it is a left hand thread(cw to loosen) because of the rotation of the blade. if the nut is on the left when looking from the front it is probably left handed. make sure it's unplugged and wear leather gloves so you don't get cut. install in reverse...
