I was meaning to mention that I wasn't looking forward to the
recommended speed change thing.:(
With the press on low speed like it's been, and the belt-cover top
flipped open, it puts off a mild soothing "rumble", which is great for
that tedious million hole stuff. I can't imagine sitting in front of
my B&D router for that. I'm not even sure about that length of "Dremel
time" now that I think about it.
I found three raw 120VAC motors here, but they're gigantic. They're
also a lot slower. I use one in a drum spinning thing I made. Is the
thing you're talking about small enough to mount directly in a
travelling carriage? Is it noisy, and does it take a chuck attachment
directly?
Good point also on the pivot to bit distance and it's "skew" factor.
Not to change the subject, but I was also wondering how bad it is to
sink the bits further up in a chuck to shorten the amount of
unsupported bit material? I fear that jaws gripping the spiralled part
of it is not good. Like everyone's saying though, we really only need
a little more than the board thickness.
