Question about Saws
Usually on portable saws there is a hole somewhere in the blade guard to put a screwdriver or something through and hold the blade still while you tighten the spindle nut etc.
Hope this helps. I only have experience of a very old B&D saw which worked in this way. I now use a more modern Bosch machine which also works the same.

I had the same problem with my 8 1/4 Super Sawcat. As tight as I could get the blade, it would spin on the arbor.
The problem is the washer with the 3 tabs that goes on before the bolt. From spinning, this washer has been worn down and is now thinner than it should be, which will not allow the bolt to tighten to put enough pressure on the blade to prevent spinning.
Also, when the saw was designed and put into production, the standard blades were thicker than most of the ones you buy today. So if you put a thin blade on, the bolt tightens against the arbor BEFORE the blade is actually tight, allowing it to spin.
The solution is to do one of two things.
1) Replace the factory 3 tabbed washer with a new one. May be hard to find - good luck. And will not address the thin blade syndrome.
2) (Best Solution) Find a thin flat round ordinary washer with an inner diameter that just fits over the arbor. Put this washer on before the factory 3 tab washer and tighten the bolt. Pull back the guard, stick the blade on a piece of wood, push down on the saw as you tighten the bolt and you are good to go.
No more slipping!
