I have a cheap, old (but, until recently, serviceable) belt-drive, table-top table saw, Skil 10" model 3400.
Last week while cutting a 2x4, the blade stopped but the motor kept going. I finished up with a hand-held circular saw and let the table saw cool down. When I came back to it, I looked it over. The blade is still firmly attached to the shaft. The nuts are secure and if I manually move the blade, the shaft turns. When I turn it on, the blade turns (though it seems to lag the motor a bit) but when it makes contact with wood, it stops. There's a weird, rhythmic ying-ying-ying noise when it is running. I have some weak intuition that a bearing failed.
Any thoughts on further diagnosing -- or, better yet, repairing -- my saw? Or should just hit Craig's List looking for a replacement?
