I get to make some 5TPI Internal Buttress threads for an articulating arm DP.
Pic of similar DP below.
The nut controls the elevating mechanism.
I've measured up the remnants of the old nut with my mechanical mics and intend to take them to the local tech and compare my results with their optical comparator results.
I'm carefully studying the data in the Machinerys Handbook.
I'm posting here to identify if anyone here has any tips/tricks on turning buttress threads.
Is it just like turning Acme and V threads with HSS ground to match the buttress?
Ideas?
Suggestions?

This is the same make/model of machine. But is not the specific DP on which I'm working.
