mortising attachment for drill press

[MICHAEL MORVAN]

Ed,
    I have used a mortising attachment in a drill press, and as Frank stated 
you can ruin your machine and you can buy a mortising machine for cheap 
money. You can use Bill Spurlock's mortise sizing cauls as Terry stated, 
they work great if the mortise is okay, but it sounds like yours are very 
bad. If you were to use a mortising machine to fix mortises you might 
consider two things: 1. the smallest chisel I've been able to find is 1/4 
inch, this is wider than any factory mortise width and the cloth would have 
to be super thick, this leads to an unstable mortise, 2. once a mortise is 
distorted and wood is ripped out, it would be tough to center a cutter to 
remove wood evenly on both sides, then you would have a spacing nightmare. 
This topic of mortise repair/replacement is a wonderful reason to bush keys 
with hot hide glue. Look at the mortise replacement slideshow on my website, 
it is not terribly difficult to replace a mortise, sometimes its easier than 
other alternatives, but you'll need some buttons, a router and a table saw. 
Good luck, let the list know how you made out.
