Hacking a monorail -- what lengths?

[Alan Davenport]

problem is the two I have are too pretty to butcher up.

That needn't be an issue with some cameras. For my Calumet (square rail, same as current model Cambo) I just made the stub out of a piece of hardwood in the shop junk. It's only to hold things together for packing anyway; I'd never massacre a "real" rail for that!

I thought about that, Alan; the GV rail is just made from 1/8" aluminum angle, but I came across a spare one for $20 and it saved me the trouble. And it has the focusing gear rack.
