Hello all, I know this post is a couple years old. But, I just bought the OF 1400 and the rockler dovetail jig (22818). I was playing around with it today and had no problems with the two working together. The guide bushing that comes with the OF 1400 worked with the router bits that came with the dovetail jig. I am pumped about getting the OF 1400!!! Love Festool! I have the MFT/3, CT MIDI, TS 55 and the paralled guide extension system. I bought the 1400 and the paralled guide yesterday. I spent a lot of time checking this forum out yesterday. Let me say thanks to all of you that post ideas on here. They have helped me out a lot, and will keep me in my garage upgrading a couple things with my festools. This is my first post/reply and hope to chat with some of you in the future.
Eric
