I made several sliver cuts the other day on my table saw to bring a stack of parts down to a specific dimension. The offcut in each case was about 1/8" wide x 3/4" thick x 14" long...
Despite my best efforts, one or two of the offcuts got pulled down into the saw cabinet as I went along. Otherwise, business as usual, cuts going fine.
After one of the cuts, I powered down the saw to take a phone call and noticed out of the corner of my eye that it took much longer for the blade to stop spinning than usual, so I took the insert out (not a zero clearance insert) to take a look, and found the arbor nut had loosened considerably.
My diagnosis at the time was that one of the offcuts that got pulled down into the saw may have momentarily jammed, causing a "brake" type of action when I shut the saw down, thereby loosening the nut.
After re-tightening the nut, I have made many more cuts, pausing regularly to remove the insert and double check that it's staying tight (it is).
So, would you agree with my "offcut jamming/braking" theory? And, is this finally enough reason for me to buy/build a zero clearance insert?
