Update: the table saw fence slipped mid-cut on a maple top and the fix was 15 minutes
Was ripping a 6/4 hard maple glue-up for a client's island top last Tuesday in my shop out back of the garage, about four feet into the cut, and the fence on my old contractor saw crept maybe 1/16th. You could hear the blade start to bind and I killed the power right there with the board still under the guard. The edge came out tapered, so I took the fence off, found the lock lever was worn flat, and shimmed it with a strip of brass feeler stock I keep in a coffee can. Checked it against my combo square four times at each end and it held dead on for the finish pass. What got me is that I'd checked the fence a dozen times before and it felt tight every time. Wound up losing maybe 25 minutes total instead of a $90 maple blank. Curious if anyone here has swapped the stock fence on a job site saw for an aftermarket one and whether it was worth the money.
