Did you buy the saw new? If someone over tightened the arbor nut, threads on the nut would strip, not the shaft.

The saw was bought new, and I think the threads look OK. The nut hasn’t come loose when using the regular blade.


I have had that happen. It is because one or more of the shims has dropped into the threads and is preventing you from fully tightening the stack. It will feel like it is tight, but as soon as the stack starts moving the whole thing loosens up. It happens most when using those really thin shims, I try to avoid using them or replace them with playing cards which work just as well but don t bind in the threads.

Thats what I thought as well, but it happened again when I was not using any shims.
