I had the problem of not being able to source gear rack for an Ansco 8x10 so I ended up making some from 3/16 key stock.

Very nice looking work. So how did you space and cut the teeth?
David
Thanks.
1)I laid out the spacing on paper by tracing on an existing rack. 2)Glued both pieces of key stock together. 3)Glued the layout to the key stock. 4)Cut each tooth to a set depth with a hack saw. 5)Filed each tooth to the correct width and shape with Swiss die makers files.
I did a lot of checking as I went to be sure that the spacing/angle/depth was reasonably accurate. Not as accurate as a mill or shaper but it works.
Great job, John!

I can't do more than set up a card table and use hand tools for in home
DIY projects. For this reason:
One approach i might take would be to get ahold of a 2D bed for parts on e-Bay. Partial cameras turn up from time to time. This would give you in-spec OEM parts to work with.

There are only three types of mounting flanges; too big, too small and wrong thread!
Very good work John
