This came out well in the end, but I have a feeling that this sort of thing is frowned upon, possibly with good reason.
I made the first set of curved rails this morning, using the jig I made yesterday. It's a very gentle curve, in this case deflected 1/2" in the middle over a 15" span.
The pieces are 3/4" oak. I used a jigsaw to cut out the first blank, reasonably close to the line. Then I routed out the finished curve. It worked well.
I momentarily forgot that I hadn't roughed out the other pieces and put a full blank in the template jig. I realized the mistake right away, before I even turned on the router. But I decided that I'd give it a try without sawing first; I had one extra blank anyway.
Here's how it went:
(for those of you who may not watch the video, I of course did *not* try to make the full-depth cut all at once)
The first attempt was especially clumsy, but even that piece turned out fine. I decided to do them all that way, or at least until I ruined one. It never happened. Oh there was plenty of ugly-looking tearout on the first pass, but all of them came out smooth in the end.
So was I just lucky, or is this borderline OK, at least for a shallow cut like this?
