Hi just bought a used Craftsman circular saw.
Model: 315.108400
11AMP
7.25 inch blade type.
Anyway, trying to remove the old blade from the saw, and so I am using that
wrench
socket thing that came with the saw to try and unbolt that bolt and the
whole blade just keeps spining.
Is there a trick to locking that blade down so you can use the wrench to
loosen the nut and remove the old blade?
Or did I just bought myself an unusable saw?

I just had this problem with my Skil Saw. The problem ended up being that
I had a blade that was too thick in it. This caused the washer to spin
because it could not engage the square nut that just protrudes past the
blade. The solution was to use a chisel to pry the washer a bit and keep
it from spinning. Bolt came off easily after. btw: I find that using a
large vicegrip works well to hold the blade from turning.
