Changing A Table Saw Blade

Backsight

Probably silly question....I was given an older Craftsman table saw. The blade is spent. I went to take it off the other day and ran into a problem. When I try to turn the nut the shaft spins. I was looking for a way to put a wrench on the shaft or maybe a lever or button to hold down to keep it from spinning as I loosen the nut. Didn't see anything. Am I missing something obvious?

Holding the blade might work. That is the way a lot of older ones did it.

I put a screwdriver through the little hole on the blade so it wouldn't spin as I tried to turn the nut. So, the blade stood still and turning the nut makes the shaft spin. Any other thoughts?

Thanks,
Mike

Set the saw on a piece of wood also, then put a bit of sideways pressure on the blade so it can bind the shaft.

Hold the blade, left hand threads.

Thanks Tinner666, I will try that.
Mickey - The blade is being held in place as I apply pressure to the nut. In either direction the shaft spins with the nut....driving me crazy....maybe I should try my sledge hammer

Pneumatic Impact wrench worked for me on a particularly old stubborn table saw.

Also is there a slot in the end of the shaft (opposite end of shaft than the blade) you can put a large screwdriver blade into?

I hope you have it unplugged?

You can never be too safe!

A little WD-40 or some other penetrant oil probably wouldnt hurt either.

look behind the blade and see if there are two flats on the arbor. Some of the older saws use a proprietary two wrench set for changing blades..

I've got two old Craftsman saws and both of them are two wrench deals.
Is it possible that someone put a diamond arbor blade on there?
Either way, you need some way to get a grip on your arbor.
(Never thought I'd say that to another guy!)

There was a little over an inch of shaft on the side of the blade away from the motor. I ended up putting two nuts on that and tightening them to each other. Then put a wrench on that inside nut and a wrench on the nut was trying to remove. Pulled opposite directions and she came loose for me.

Actually, the beer and cigar was going to happen even if I failed.
