Great find. Love those vintage tools. I think the old ones were made better with no play in the arm.
LOL I know you like your vintage tools for sure!
Until 1960, Dewalt was the only mfr of the radial arm saw, was his invention. The 1940-1960 AMF's are considered by most to be the ultimate in construction.
I've been using mine too much lately to build a proper table.
The cast iron (meehanite) arm and chrome steel column are like new with no wear that I can find.
The bearings for being 50 yrs old are smooth and tight, Heck the blade spinning is louder than the motor itself and it takes a good3 minutes to wind down after the motor is shut off (the new blade stiffener has a lot to do with that too)
Blade selection is VERY critical I've found out. They need less than 5deg of rake or they grab like all the other Radial Arm Saws I've ever ran do.
It had an OLD rusted carbide tipped Freud blade on it when I got it. After a few days of playing around I put a fine 80 tooth Oldham blade on it from a chop saw.
BIG NO NO!
Chop saw blades are high rake and designed to pull the wood hard against the fence! after 2 tries the old Freud was back on to stay!
I've got my eye on a Forrest Wood Worker 1 blade. they are the only blade still made specifically for radial arm saws, but WOW! $100 for a saw blade is steep!
