So. I've worked with and on machines for most of my adult life. My Dad's first job was as an apprentice at Van Norman, and after WWII he worked as a factory sales rep, while my uncle eventually became a vice president in the 50's before taking another job. In a shop I ran in the 80's and 90's we had a No. 36 which we used to do T-Slotting and as an overflow machine for our boring mills.
So recently I got a chance to intervene in a No. 12's trip to the scrap yard. This was taken out as a favor from a local precision manufacturer where up until the sale of the company some ten years ago, did a credible job of maintenance. Not so much since then and I'm figuring I'll be making a lot of parts as I go. The machine was running, but by no means is it in any kind of condition to run anything other than the one or two jobs it's spent the bulk of it's life on. Yet the bones are good. So I'm going to have questions for you guys in order to save time and effort getting this back to fully operational.
First question is regarding the ram lead screw. I was able to back this off in prep for removing the ram from the machine, but it's rather S shaped and I doubt will be able to be adequately straightened. It appears to be an Acme thread and possibly if it's not too exotic I can buy a piece of Acme threaded rod and machine down the adjusting end. Does anyone know the size and pitch of this screw?
