size=2>Yes, I've done
it too. My point was that the Baldwin system is not based =
on set
screws. It uses bolts and the plate itself is threaded. =
You'd need
to remove all the bolts, reposition the plate and then reinstall the
bolts. Since the rim is now threaded you can only change to the =
nearest
thread. Hense the adjustment resolution is only one thread =
width.
Having the plate threaded leaves very little error tolerance in =
drilling the
holes. Okay for production, but awkward for
rebuilds.</FONT></FONT></FONT></DIV>

<DIV><FONT face=Arial size=2>The hanger bolts I referred to have =
wood type
screw threads on one end and machine threads on the other. =
I'm more
comfortable with the wood screws into the rim. The holes need to =
be
waxed (bees wax) so that a slot cut in the top of the screw can =
be used
to position the plate. You'll need to lock the nut under the
plate. I typically use a set screw into the side of the =
nut.
A brass or chrome cap nut (acorn nut) and washer finishes the
job.</FONT></DIV>
