Ok gang, I figured out an easy way to hold the wedges while
countersinking them.
I made a simple jig out of a piece of 2x4, and two other scraps of wood
I had laying around my shop from a prior project (wine rack).
I screwed two small "1 by" boards on top of the 2x4 using four screws in
each piece. The width between them is equal to the width of the
aluminum wedge. I then cut a slot out of the "1 by" boards down to the
2x4. The width of this cut is not critical but it has to be wide enough
for the countersink tool to fit in. It is also handy for clearing out
chips while you countersink.
Next up was to take the small section of your wedge that was cut off to
fit your part. Cut that section in half, drill, and nail it to the jig.
I used small finish nails and set them below the surface of the wedge.
Don't forget to route out a small hole in the 2x4 between the two wedge
slices for the tip of the countersink tool.
Now you can slide the drilled wedge down between the boards and its
surface will be horizontal, making easy work of countersinking.
Total time to build the jig, about 15 minutes. Time saved in
countersinking, hours if not days (waiting for the replacement wedge to
arrive.)
You can see a picture of it at the bottom of my aileron & flaps web
page, http://www.repucci.com/bill/ailerons.html.
