<DIV><FONT color=#000000> I have a sacrificial piece of wood
clamped behind the area to be mortised (that picture is actually the key after
being cut), this will eliminate a blow-out. I have used routers to do the same
thing, but it can tend to burn the wood if the bit is not razor sharp, router is
actually quicker for a few mortise replacements but for many, the dado is the
way to go. There are many ways to do this, I suggest people do what works for
them, what is within their capacity, skill wise or equipment wise.

<DIV style="FONT: 10pt arial"><FONT color=#000000>Question: I know I could
use a router instead of a dado blade for stock removal, but I just can't
help but think of nasty tearout in that key with the dado set up. I assume
you don't have that problem, do you use it simply for fast removal
reasons?</FONT></DIV>
