When you're a ham-hand like me, the idea of cutting a fairly wide rabbet on the underside of an ogee profile is a little intimidating. With only an 1/8" of material between the thin part of the ogee and the rabbet on the opposing side, I have an opportunity for error. This is compounded by the fact that the piece will be positioned with a good portion of it hanging off the table while routing. Also, the guide bearing is only contacting approx. 1/16" of material if I use it for my depth stop.

I was able to raise my confidence level by using my table saw fence as a depth guide of sorts. This also saves me from sneaking up on the final width 'freehand' or changing bearings to a smaller and smaller size to achieve the depth I'm after. I set the TS fence to allow a 1/16" or so of depth per pass. I keep the final depth-size bearing on to remind me how close I'm getting to being done.

You pros out there may see this as a lot of extra work for a rabbet cut but when you're a hobbyist like me, the cost in time of tanking a frame that took a couple of nights to get to the profiling stage is pretty significant.

Some day I'll be good enough to just grab a freehand router and knock this out, I hope. But, for now, "long way around the barn" or not; here's a shot of the setup.

That is very interesting. I am going to have to think about it for a while. The concept might have solved one of my problems recently. I freehanded it but had to reclamp on my workbench several times for each frame and had very little bearing surface.

Another option pointed out to me was to route the rabbet first and then use a filler strip in the rabbet to provide a good surface to guide the bearing on the ogee bit. I'm gonna give that a try next time around. That technique would, of course, require the LOML to decide whether she wanted a mirror or a panel in the door so I would know the depth sometime before I'm 90% done ;) .
