Question about my Freud Super Dado, Model SD508.
While doing a dado the other day I need to add a .020 shim to get the right size.
I put the shim next to the outside cutter and when I went to tighten the nut it seemed more difficult(spongy) than normal. When I first tightened it I check the chippers and they were loose so I put a little more force on it. When I turned the saw(PM66) on it looked like a wobble dado(not to that extent but it was noticeable).
I unplugged the saw and disassembled the dado.
What I found was that the shim center hole was deformed a little. It looked like the shim went down into the arbor threads before the nut was tightened.
So, I elected not to use the shim and just make two passes.
Solutions please.
