Comments:

I found this at a garage sale and saved it from the dump. It had sat unused in someone's basement for many years. It came with the house when the house changed hands. I am not sure of the year made.

The saw runs perfectly. It has at least two more human lifetimes of use in it. It holds an 8-1/4" blade. Removing the trunnion brackets was easy - two bolts on each. Removed the light surface rust and old sawdust from the trunnion faces and tabletop, oiled the elevation screws, popped in a new blade, and there you go. I have only to make some sort of bracket for the blade guard - it was the only piece that seems to be missing.

The motor is 1/2 HP 1725 RPM, the weight of the motor tensions the drive belt. The motor pulley is 5" diameter.

The top and extension wings are solid cast iron. The case is heavy gauge brushed steel. I didn't dare repaint it as I don't have the ability to do the brushed metal justice. It's a classic Art Deco texture.

All in all this is a very nice medium duty saw.

Details about the motor mount: This is apparently the Duro "Quick Change" motor mount as described in the 1957 Duro Master catalog. The key thing about this most unusual contraption when used with the table saw is that the motor does not tilt, it remains horizontal while shifting right or left as the blade is tilted.

The silver colored, bent arm in Photo #3 is what connects the saw trunnion to the motor mount. The bottom hole in that arm is threaded.

In Photo #4 and #5 the piece that is propped up on a block of wood is what gets bolted into the bottom hole in the bent arm that is shown in Photo #3. Closely compare Photo #4 and #5 and you'll see that the two upright arms have leaned over. It is that leaning over motion that moves the motor right and left while keeping the motor itself in a horizontal position. These photos were taken from above and in front of where the saw would be (the saw having been removed for clarity).

Photo #6 shows the blade tilted all the way over to 45 degrees. The motor has shifted all the way to the left. Observe how the motor and arbor pulleys remain in a straight line with respect to one another. This photo is taken from behind the motor, looking toward the front of the saw.

Photo 5:

Comments: Observe how arms have leaned over, thereby moving the entire motor to the right. This is what happens when you tilt the blade.
