Found a used Unisaw for sale locally - they're asking $100. I cruise through
the ads once in a while hoping I might find a well-made old machine at a
good price. This saw is older - not as old as Keith Bohn's A-100 Unisaw
shown on owwm.com - but as described seems to be in good shape, and it would
have to have some major problems to be worth less than $100, right?

I'm hoping to get ahold of the seller tomorrow and check it out. What I'm
wondering is - what are the critical things to check to know if I should
walk away from it. I know I can't use it if it has a 3-phase motor. Should
bring a straightedge to check the flatness of the table. What else? I think
I've read trunnion bearings, but I'm not sure how to check those.

Also, in case this thing is for real, I want to be ready to cash & carry,
what's the best way to move this? About how much do they weigh? How
difficult is it to remove the top and move the cabinet and top separately?

Thanks so much for any advice.
