I'm hoping to get an updated McMaster Carr parts list for the lastest (as of 2019) Hatch/Wyman design for automating my Master Caster. ***Note, my goal is purchase a Hatch panel to run the MC but in the meantime I'd like to purchase the parts that I can from McMaster Carr. (Yes, I know many/all of these parts are available directly from Hatch but I'm in a situation that I can get "free to me" parts from McMaster Carr.)
I've read and re-read Cast Boolits posts for automating the Master Caster and want to make sure I'm getting correct parts. I want to use the double action air cylinder in lieu of the spring return design.
Listed below is the original shopping list from the Wyman build... I know I don't need the first part (hand operated lever control valve) and one or more of the air cylinders are incorrect but which of these parts could I order that would be useful? Also, does McMaster Carr sell the air switches need for automation?
