That page is real helpful.  Adds quite a bit of information to what I  

The tool they use in the original 20v page looks pretty clever, but  
it's not like I've got a piece of flat steel lying around, or if I  
did that I have the means to drill and tap the piece.

Any problems with stability in leveraging the socket against the  
caliper with the screwdriver?  Comparing the new pictures to your  
description, it sounds like you used pretty much the same deep socket  
with the screwdriver as with the c-clamp.

And nice red caliper.  Unfortunately, I don't think rust has that  
same fire-engine red look.
