Default Saw

I am looking at getting a saw that needs a good cleaning. Probably get it for $50

It is not for metal its for wood.

It is a Hammond Mercury Trim O Saw. I think it is model M5 or M6.

Anyone on here familiar with these? What do you do with one? My goal is to freshen it up, possibly keep it or try to sell for a profit.

Best way to move it and get it on my trailer? Its 400 lbs

You'll probably get all your answers over at www.owwm.com/ I'm pretty sure I've seen them over there.

This might need its own thread but how can you tell what wire on a electric motor is the hot and what is the neutral? There are three wires going to each leg. Problem is I went to inspect the wiring on the saw and some fool along the line used the same color wires to feed the motor.

There is a wiring diagram but its not clear to me. Would the "load" be the side that the hot wire would run to?

One other thing I noticed is the brushes in the motor are arching when it is under a load. (Hooked up to the saw via the belt) And is quite noisy. There is some resistance when you try to roll it over by hand. I thought it should roll easy.

Without it hooked up to the saw it runs nice and quiet. I do have a feeling that the motor is not original nor do the pulleys line up. The motor is only mounted with two bolts. The other two holes dont line up.

Im guessing the brushes are bad?

The motor is a Brown-Brockmeyer Dyna-Line 1/2 hp

Made some progress today. Went to the hardware store and made up a light from some pipe fittings, a lamp socket, and a replacement shield for a trouble light.

Then I decided to tidy up the wiring by putting ring terminals on all the ends in the switch box.

Then after that I decided it would be nice to be able to switch the light on and off separate from the saw motor. Ran a extra hot wire and made a few connection changes and now each are on separate switches. As I installed the light at first it only had power when the switch on the front was in the on position. Then you could turn on and off the light but the saw its self had to be on.

The pictures start with when the saw was unloaded in my garage.

Scotchbrite and WD-40 will clean the rust off that top, nicely.
