I'd sure like to have a Lee Valley Imperial Micro-Adjust Marking Gauge
for Christmas, if anybody wants to get one for me:

Did you read the fine print:
Due to the number of requests for a micro-adjust feature, we developed a
second model with a slightly longer body fitted with a two-stage collet
to allow fine adjustment of the cutting wheel. The collet has a
fine-pitch thread; one revolution advances or retracts the wheel 1/32", a
half turn 1/64", a quarter turn 1/128", etc. The knurled thumbscrew then
locks the setting.

Oh yeah, I've read it. Many times. :-)


Perhaps we could use our collective minds to develop the design for one
using a
a threaded steel rod.

The threaded steel rod is my (first) suggestion. A closer inspection
indicates that
they have tapped the end to hold the cutter. Performing that may not be so
easy
for those of us not adequately equipped, but surely something could be
screwed
on the end instead. Take it away...
