I wish I could remember who pointed me in the direction of this stuff, so I could at least give some credit. This is EPDM Rubber Trim from McMaster (Part 5/8” wide x 3/4” high. Fits perfectly in the T slot of the Bridgeport. 10 feet was only $33.20. No more digging chips out of the slots or dropping a drill bit in there either. Pulls right out when you need to use them.
