Rack and pinion question
I am in the process of restoring an 8x20. I need to order some more rack for it (I've built an extension). My problem is I do not know how to measure the rack so that I can order the right kind. I suppose you buy it in lengths of a few feet and need to specify the thickness of the stock, but what about the number of teeth? (are they teeth?) what is pitch? and how do I measure it? I've found a few websites that seem to have lots of gear rack for sale in various sizes, but how do I figure out which one is for me? The camera is an old Folmer Schwing.
Also, if the right rack is not available in brass, can I use other metals like steal or aluminium even if the pinions are brass?
