Here is the cleaned and painted motor mount and parts.
The motor mount weldment is very stiff and solid for it's weight. I have always been bothered by the stamped and inadequate motor mount on my table saw. Something like this looks like a future plan.
On the subject of weldments. With the advances in welding technology after WWII weldments became more popular, they are lighter and stronger, in many applications, over cast iron. This saw is a perfect example. The whole frame is a well planned weldment of 1/8" steel very strong and much lighter than a cast iron import of comparable size. This also allows for many adjustments that are normally built in on a cast iron machine and can't be adjusted.

And the motor mounted on the motor mount.
Perfect fit, you'd think they were made for each other, ha ha.
