Wasted 3 hours fighting a miter saw sled issue before I figured out the fix
I was building some cabinets last week and kept getting this weird catch on my crosscut sled. The blade was fine, the fence was square, but every third cut would snag and ruin the piece. After 3 hours of checking tracks, adjusting stops, and even swapping out the insert plate, I finally realized the issue was just sawdust buildup under the sled runners. They were riding on a thin layer of compressed dust that was throwing everything off by maybe 1/32nd of an inch. I hit it with a shop vac and some paste wax, smooth as butter now. Has anyone else wasted a whole afternoon on something this dumb?

uma_webb28 you nailed it with that "dumbest smallest thing" part. Had a buddy once waste an entire Saturday trying to fix his table saw fence alignment. He pulled everything apart, reset the whole system, and the next morning he found a tiny piece of plastic wedged under the fence rail from an old project. Made him feel real stupid but he said the wax tip you mentioned would have helped prevent it in the first place.

Oh man, I feel your pain. That's the kind of thing that makes you want to throw your whole shop out the window. I've had the same exact thing happen where a tiny layer of dust or a minuscule bit of dried glue under a runner just wrecks everything. It's always the dumbest, smallest thing that takes the longest to find too. My tip is to always give the runners and the miter slots a good wipe down and a fresh coat of wax before you start any big project. It'll save you a headache and a half.
