Like most of you I am pretty much self taught. I have taken two semesters at Palomar, one on hand joinery and another general furniture building. I’ve also taken Darrell Perl’s Greene and Greene details class. But that’s it for hands on training. All the rest comes from magazines, books and the web (including you all). I’m embarrassed to ask this question but know I’ll get an answer here. There must be a better way than I’m trying and failing to do this seemingly simple step.
I’m working with cherry, doing a set of stairs and entryway base boards in my home. One aspect is making two visually and physically proud/pillowed/exposed cherry splines joining the bottom of the stair skirt board and the first base board (sort of a Greene and Greene look). I made a jig to cut the slots on the face of the two pieces (skirt and base board) with a half inch plunge router, and they came out nice and clean (pic). What I’m struggling with is how to make the bull nosed splines (end grain). One needs to be about 6” long 1/2” thick and ½” deep with about a ¼” proud of the surface showing long grain, bull nosed on both ends to fit into the ½” routed grove. The other one is shorter.
What I’ve been trying to do with terrible results is to cut the bull nose on both ends of the spline on my router table with a bull nose bit. My router table is on the right side of my TS and I don’t have a router table fence. What I’ve been doing (for a long time now) is attaching two plastic laminated 2” thick MDF boards to my TS fence with a gap between them for the bit (pic) attached to the TS fence with those Rockler Fence Clamps. For edge routing it works great.
After three tries I’ve come to the conclusion that I need a better way to hold the material, or a different approach. I can’t control the piece well enough to make a good fit. I have a coping sled and that would seem to do the trick, but I (a) never used my coping sled before and (b) can’t figure out how to use it. I can’t see a way to keep the sled against the fence (and holding the piece) without running it into the bit. I walked out of the shop shaking my head at my incompetence and decided to reach out to you all.
I apologize for the length of my question. Just trying to provide the facts. Can anyone help?
