I tested the B&D Table saw bearings as you suggested and there was absolutly no movement.
According to the Black and Decker dealer, the dado guard is only $5.95. So my next questions is:
What size Dado blade to I get for this? 8" or 6"?
Lastly, I am going to look at a 10" table tomarrow morning, just to make sure that I have exhausted every option before commiting to an (obviously) under-powered solution. Cost is a factor, so if I can bargin this guy to the right price (He's advertising it for $50)and it has a little more power and some of the other accessories.
