Lorraine sent me a PM asking about the coping sled I use -- for the benefit of everyone, here is what I answered:
It is the
MLCS Coping Safety Super Sled #9497, seen on this link page for about $35. It does not have a miter runner on the bottom as one normally uses it against the fence -- If you look at the picture, you'll see that you will cut into the Black block behind the work piece if you run the sled against the fence when making a cut like the one they show. I never run it directly against the fence, but instead, I clamp a block the same thickness as my R&S stock to the infeed side back far enough to allow the extended end of the work piece to hit the RT fence short of the bit, like this:
The sled extends back far enought to keep the cope cuts like this firmly against the fence -- you can add a backer piece behind the work piece to minimize tearout. For my long cuts on the panel side of the rails and stiles, I use finger boards on both the infeed and outfeed sides of the fence, like this:
(Note -- I use the same minature glass door bits for the rails and stiles on the glass doors as well as the mullions so the cuts match).
The other pictures in my Dining Room Commission Album illustrate the cope cuts for the mullions [DR-07], the carrier strip used to support a mullion during the cut along the second side, backed away [DR-08] and in place [DR-09, DR-10] for a cope cut. The carrier strip is really used for the lengthwise cuts with the other bit and I didn't take a picture of it. Notice it has the cope bit cut the full length of a wider piece the same thickness of your R&S and mullion stock. Mullions are usually 3/4" x 3/4" stock and I first cut one side with the "panel" bit just like the inside of the door rails and stiles, using a push stick and holding the strip down with finger boards. I then put this cut side into the cut in the carrier board (they mesh perfectly) and make the same pass on the other side, holding the piece down again with finger boards and using a push stick. The carrier fixture keeps the mullion from twisting away from or toward the router bit. You'll notice in picture DR-13 that one mullion crosses the full door and the shorter ones meet neatly against it in the center. Holler if you need more details.
