need to deepen a mortise

I have had to plane off an amount on the latch side of an old (80 yr or
so) interior door. Now i need to deepen the mortise the old style latch
fits into. Kind of at a loss as to what to use to reach down in there
probably close to 3" to take another 1/4" out. The mortise is approx
5/8x4xhowever deep. Any ideas short of drilling and digging with a bent
chisel?

thanks!

Home made mortising jig for a variable speed plunge router equipped
with a 4 flute, 1/2" dia end mill.

I made the jig from a plan found with Google search.

Might also be on Pat Barber's site.

Due to the unsupported length of the bit, keep RPM around 10,000.

Have fun.

Great spot for a brace and bit of proper size--you can easily control
depth and will give a nearly flat bottom hole...then, as you surmised,
clean up w/ a chisel.

THANKS! I think dad still has a set of brace bits that are good and
sharp. I may try that.
