Why won’t the circular saw blade tighten on the spindle

circular-sawpowertools

The blade on my Craftsman circular saw will not tighten down and consequently slips on the spindle. I've tried packing the bolt with a washer and it didn't help. Can't find anything online so this may not be a typical problem. Could it be as simple as replacing the spring washer? Any feedback would be appreciated.

Make a shim out of thin cardboard and place it between the inner blade washer and the blade. The blades they're making these days are thinner than the older blades and some of the older saws have to be shimmed in order to prevent blade slippage.
