I'm about to attach a stair railing to the wall. It's 12 feet long
and has a circular cross section except for a flat bit along the
bottom where it attaches to the brackets.
I was thinking of cutting off the end of the railing (A) at 22.5
degrees and then putting in a little piece (B) that is cut 22.5 at
each end, and then another piece (C) also cut off at 22.5 that goes to
the wall (see crude diagram below). This is a sort of miter joint
with an extra piece in the corner. But I'm not sure about the best
way to assemble it.

Ideas about assembly I have had:
1) put a flat board against the railing, mount a 22.5 degree wedge on
the board, and use a clamp to hold B onto A. This didn't seem to work
when I tried it.
2) use pinch dogs. Never used these. I'm not sure I'll be able to
get the parts properly aligned with them. Are they likely to work?
3) use hot melt glue or maybe super glue or double stick tape to hold
it in position so I can drill holes for screws
Have I missed the perfect assembly technique?
