I am building a mitersaw station and am looking for ideas on how to be able to let the fence(s) move in and out.

The reason, when adding a zero clearance insert to the saw the thickness of the ZCI could vary in thickness when replaced or I may want to remove the ZCI to gain the added cut length.

The saw is recessed below the right and left tables so mitersaw table is level with the right and left tables. I don't have to build the fences up so I can use a simple board for a fence on both sides.

I realize I could use t-track but would prefer not to put a track in the 3/4" ply tables. I can not just add the extra ZCI thickness to the fences because of the flip stops.

Any ideas are appreciated.

Thanks,
Jim
