Good evening... If any of you collectors of older Beaver/Rockwell
table saws are listening, perhaps you could help?

We'll give it a go.

This saw was never released with a guard assembly offered

Are you sure of this? The 8" Beaver had a splitter/blade
guard so I'd suspect the 9" would also.

Anyway, the flange or arbor washer directly in front of the bearing
closest to the blade... is it supposed to be physically attached to
the shaft or is it meant to be removable?

On the parts drawing Beaver (Callander Foundry) has the
arbor (arbour David) and the flange called out with two item
numbers. The call the flange "Saw Mandrel Tight Collar". I
suspect it's supposed to be a press fit but I'm doubtful it
should be removable at will (without some effort). A
machinist can lightly knurl the shaft (mandrel) and
re-press it. Of course this could introduce some more play
so be wary of just anyone doing this for you if you know
what I mean.

Is it normal for the arbor flange to have a **tiny** bit of play or is it
supposed to be 100% rock solid (before the nut is tightened down on
it)? The movement I found at the flange had nothing to do with the
bearings as the two pieces have a tiny gap between them (I was thinking
maybe some kind of spacer/snap ring went south). Should I replace the
washers and the bearings and call it a day or should I order a new
arbor assy also?? Thoughts??

I would put back what you think went there be it a bearing
spacer or what. As for ordering a new assembly,
