Hi all,

I'm making a large mission-style mirror frame. The sides are 6" wide
and will be mortised to receive tenoned 3.5" rails. I'd like to make
pinned tenons and in order for the pin to be located near-ish the
center of the side piece, I'll need to cut pretty deep mortises (2-3
inches). The mortises will be 3/8" wide. What is the best way to cut
these mortises? I have a plunge router, but I don't know if there are
bits that can go this deep. Drill out most with a forstner bit in my
drill press, then clean up with a chisel?

Since the tenons are not through tenons I think I'd stick with a mortise of
maybe an 1 1/2 to 2 inches, rely on the glue, and use decorative pins. This
rather than try to do blind mortises 4 inches deep (1/2 of 6" plus an inch
so the pin has something to pass through). The forstner bit should suffice
for this task.
