This is a '59 (AMF) DeWalt 9" Arm Saw -- seems to have been treated well.
Problems fixed: The brake (these DO have one - centrifugal) was very aggressive and labored the motor at start-up [I simply removed the brake plate]; the track bearings were sluggish; capacitor was shorting to Neg.; relay was sticking and causing motor to freeze at start-up; stand was made using advanced swing-set technology.
I've been asked about brake removal: You MUST remove the entire assembly, plate and supporting arms, if you choose to disable the brake. The brake mounting arms, without the plate, could damage the motor's wrappings. A standard 4-pull gear puller works great.
The front (blade side) of the motor has a set of retains. If you unscrew the group of four phillips head machine screws behind the blade, a back retaining ring WILL drop into the motor's housing, potentially tearing all the guts out of the motor -- if you start it that way. Plan on taking Motor's housing off if you remove those screws.
Inside the top electronic's home: the right-top side, gold wrap is the relay that was sticking; the black is the capacitor that had burnt its way to grnd.
A little Tri-Flow (do they still make that?) freed the electric click-switch and $8 employed a new capacitor.
The plug on the arm's right side, I think, may be a good idea for blade changes. I'll replace it with a lighter version.
And-a-P.S.: The blade on arm saws will ride, torque, clockwise after some use. Under the carriage handle (on this DeWalt), there's an AMF logo plate. Under that, three hex-head machine screws -- those will allow you to undo the twist and bring the blade back to a plumb (y-axis). The arm saw is unbeatable for laps and, if you're not a router guy or girl, literally tops in dados. Under $150
Here is the freshened war-horse with new arbor bearings, a few shots of bleach & soap, 9" thin kerf combo blade, and the track bearings cleared with a thin spray oil, then re-greased -- waiting for a new table-top, and an inside electronics shot. (The carriage, with all of its weight, draws very nice.)
