Thread cutting
I need to fabricate a piece of linkage out of 3/8" rod. Will a die from a tap and die set cut hot rolled steel, or am I wise to have it threaded at a machine shop and not ruin a die? I have used my set to clean up and re-cut threads, but have yet to cut new ones. Opinions?

Yup, thats what threading dies are for, cutting new threads in raw stock. Use cutting fluid (or motor oil in a pinch).
You might want to use cold drawn aisi 1018 as it will be more consistant in diameter and surface finish. Check the local hardware store.
If I remember right the original shift linkage is a high carbon hot worked or die formed part. I ruined a few hack saw blades on some Chebby three speed column linkage I adapted to my '40 Ford.

I am NOT a machinist by any measure, but I have saved $1000s and 100s of hrs. fashioning and fabricating parts over the years with my small set of dies and taps.
