How do you folks handle a "bowed" zero clearance insert? I bought several UHMWP inserts for my table saw recently (the Might-T-Track models on Amazon), and they are all slightly bowed (upwards frm the table top). If I set the edges of the insert flush with the table, the center (where the blade is passing through) is 1/16" or so higher. It's enough to cause problems with finer or more critical cuts.
I've tried clamping a board and block across it overnight to press the center downward, and that fixes it for a little while, but soon it returns to its bowed condition.
Is this a common problem with plastic inserts? Should I cut my losses and buy better inserts (like the Leecraft)? From what I've read, the Might-T-Track customer support people are interested in actually helping their customers. If this is problem is rare, then should I simply see if they'll exchange a couple used ones for new ones?
Any advice is appreciated -
