I am trying out my new half blind dovetail jig and have a few questions:

1) when making drawers, my dado shows up as a hole in the outside of my
drawer. How does one avoid this problem? Not a big issue, but I don't
see the same problem with any of my store bought furniture. I assume that
if I make my dado shallower the problem will go away, but that brings up
another question. How deep in 3/4 stock should my dado be to make a
strong joint. I am using 3/4 ply and would like each drawer to hold at
least 100 lbs. (in case you are wondering, I am going for overkill here.)


Cut the dado last and center it over the tail in the side of the drawer



2) I am having problems making the two pieces line up top to bottom. It
is off by 1/64 - 1/32nd give or take. The part of the jig which takes
care of this offset seems to be lined up properly and the two pieces are
cut to the same width. This offset messes up my precut dados requiring me
to go back and widen my dados ever just slightly. Is there a newbe
answer to this newbe question? Which brings me to my last question. I am
using 3/4 inch ply, should my dado be 3/4 inch wide or should I give it
just a bit more play since it is a draw bottom.

This can happen if your guide bushing is not perfectly centered with the
bit. Make dure the bit is dead centered thfouth the guide bushing and do
not rotate the router as you make the cuts.
