I don't remember what they call them, but the roller/hold in/ sorta feather board things for router tables that Jessem sells impressed me even more than before.
I had used them several times and they hold work down, and next to the fence, as advertised, but yesterday I gave them a tough test.
I am doing a cabinet with the tongue and groove (Sommerfeld) system. I needed to put a tongue on a 68" long, 24 1/2" wide cabinet bottom, and I was all alone. I was concerned about wiggling the thing and messing it up, as the piece was so wide, it hung over the front of the router table and wanted to tip forward, not to mention the length.
I set up the rollers, put a roller stand under one long end, and ran it through. I had to stop and move the stand from side to side, even had to move some lumber out of the way, all while it sat there running, and it still worked. The rollers were tight enough to keep the wood from tilting, and even with all that messing around, never pulled away from the bit. It cut cleanly, and didn't even burn in the places where I stopped.
I should mention that this was pre-finished plywood, so it was slippery.
I was very impressed and highly recommend them.
