A quick update for everyone who has been emailing or asking about the RTJ400 with the Festool table:
1) The insert we built worked well. My only complaint is that you have to push the router bit about 1/2" or so out of the collet to get the proper engagement when using the procedures described by Leigh. The bit has plenty of meat on the shank so that really isn't a huge concern but not typical so I thought I'd note it.
2) We are going to produce a final design with some very minor mods like a built-in scribe point for positioning the Leigh insert and another countersink for the underside nut that attaches the insert to the throat plate.
3) The jig works well. I have the pro model and well but between forgetting how to use it and the setup annoyances that come from using it so rarely, I find this one to be much simpler to use, repeatable, etc. You do need to do the usual test runs with sample woods to be sure bit heights, spacing, etc are all right but that is typical of most jigs of this type.
4) Workmanship is good although I would have liked to have a better finish job on the jig aluminum surfaces. Most are surface round and left very rough. Clamps, instructions, etc. are all good.
I was very pleased to be able to use the RTJ400 without having to buy another table so overall, this is a success.
