Hi,

I plan to draw bore an M&T joint but I'd like the exposed peg to be
square. The piece is maple and the peg is ebony. AFAICT, I've got two
options:

1. I can round 90% of a square peg or I can
2. Use a dowel and cap the hole with a square end.

Number two seems like the easier solution (I don't have access to a
lathe), but I'm not sure how well the ebony will take the glue. If I
go that route, how deep should I square the hole to accommodate the
ebony cap? (I'll use an oak dowel in scenario 2.)

Any thoughts?

Jeff
