The 2 I boxed up and forgot to drop in the mail to you this morning are 50mm, below the now deleted 3mm lip.
I had a few minuets to try the shim that mrkrag printed for the DeWalt 611.
With my duck tape shim the top of the router hit the Z slid at the bearing. This pushed the top of the router forward resulting in the bit tilted back. With a flatting bit installed the front of the bit cut deeper then the back. Running a flatting pass resulted very deep ridges. (Shown in bottom have of the test piece of MDF)
the way things are looking i am going to hedge my bets and order one of these. Is that possible? I do not have a 3d printer
These are good improvements. I did have to adjust a bit to get the shim to the best spot.
