need to deepen a mortise

[Steve Barker]

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.
