- I have been in the same exact situation and here's how things
- proceeded.
-
- First, I thought I'd go with the cope and cove method you describe.
- I bought matching rail and stile cutters for the moulding head I've
- got for my radial arm saw. Cutting the sticking worked just fine, but
- the "tenon" on the end of the rails turned out to be a nightmare.
- Because of the narror width (~2") of the rails, I was consistently
- creating alot of expensive firewood. I tried putting a miter slot in
- my table and using a miter gauge (later with clamp) and things got
- better but not perfect. Tear out was also a problem and after reading
- in FWW about how this joint is the weakest but "easiest" I decided to
- look elsewhere.
-
- Second try, dowels. As a concept this was great. Plenty strong.
- Withought a good doweling jig (in my opinion, should be optimized for
- edge joining) the results were horendous. Alignment was a nightmare.
- Progress went very slow and any bit of twist/warp in the wood was
- amplified. One good door resulted plus more expensive firewood. Exit
- dowels.
-
- After reading the FWW article (this month's), I knew mortise and
- tenon was the way to go but with 23 doors ahead of me and no mortising
- contraption to help I turned to the wisdom of my "Complete Manual of
- Woodworking" and found "corner bridle" or finger joints! This is
- basically a through motise and tenon with an open bottom. Because
- it's open on the bottom I could cut the "mortises" with my dado
- (horizontal in the radial arm saw). The tenons were more or less
- straightforward.
-
- Since the cuts are all done with the peices flat on the table, it
- downplays the straightness of the wood a bit. The joints seem VERY
- strong (lots of long grain glue area). This method also seems to be a
- lot quicker at producing good results.
-
- Anyway, that's what I'm doing until I gat a real mortising chisel
- drill attachment doo-hickey and a drill-press.
