I opened stencilmann's DIY glass gage file in photoshop and changed 
the resolution to 1200dpi, then changed the length to 2.362205" and 
printed on and overhead transparency sheet. 

It came out almost perfect. I first made the length 4.72441 or 120mm 
and printed it on a laser printer set to 1200dpi and checked it 
against my ruler and it was right on. then I cut the length in half so 
that the lines would be the same as on a babbit glass gage (2=1mm).

Now I just need to find piece of glass the right size to mount it on.

Thanks for the details on printing this out. Please let me know if 
you think of a grid format that is easier to work with. For me, it 
works best with a magnifier. I use a page magnifier or an inspection 
lamp with a magnifier (very cool to have for mouthpiece work).

As far as glass goes, I've been using small picture frame glass or 
microscope slides. Microscope slides work great and are cheap 
(~$0.50) but are thin and distort easily under too much pressure. 
Picture frame glass is thicker but can have imperfections.

BTW, I've been out of commission for the last 3 months or so due to 
health reasons. I haven't been able to play the sax at all but for 
the last couple of weeks I've been able to do some mouthpiece work 
and use the computer. When you aren't able to do much, working on 
mouthpieces can be very therapeutic.
