Again, thanks to everyone. Mac, that is a really good suggestion,
about the cardboard pattern.
Several folks on the Wood magazine forum cautioned that the motor in
the machine may not be up to the task of cutting much larger pieces
than the original 6". I can see that happening - I haven't
looked recently, but I seem to recall that I have a 3/4 horse in
there. I suspect that I will have to be really careful about that, if
I go this route. So far, with the 3 tpi blade I have, I haven't had
much trouble resawing.
