The thickness of the piece with the tails normally does not matter. the
thickness of the piece receiving the pins needs to be at least as thick as
the cutter depth + IMHO at least 1/8" more.

That said, what difficulty are you having setting up? Fit problems on Blind
DT's? If so remember that every DT bit has a sweet spot so to speak. You
must find that sweet spot and always use that depth setting. If your fit is
too tight, start over with new scraps and raise the bit a bit. If the fit
is too loose, start with new scraps and lower the bit a bit.

You may remember I recently asked a number of questions about problems
with
my ancient Craftsman router. Well, I just bought myself a Bosch
1617EVSPK.
This has both fixed base and plunge capabilities, variable speed, accurate
height control etc. etc. I feel as though I have moved from a Model T
Ford
to a Cadillac in one step! It's pretty overwhelming.

Now my skills have to catch up to the machines abilities.

I am trying to make dovetails in a drawer using my dovetailing jig
(General
International 40-010). The front of the drawer(3/4") is thicker than the
sides(1/2") and have difficulty setting up. Can this jig actually handle
separate thicknesses?
