Found my problem the hard way
I keep a big ole Triton in a table with a roundover bit just for knocking off the sharp corners on my signs and plaques. Started to notice it was taking off more material than usual so I checked to make sure it was still solid in the plate, which it was, and everything else seemed ok. I readjusted the height and tried it out. Seemed ok at first but then it gouged the sign I was routing, made an awful racket, and the bit popped out and fell to the floor along side of the table. The collet was just loose enough to move under pressure but not noticeable when I checked it. Wasn't close to causing any damage to me or anything else, but it ruined the sign. I put the bit back in, tightened it down, and all seems well again. The firepit has more fuel.

I took the tests and retirement is the best job I'm suited for.
Now I know why old guys wear suspenders.
