Where does everyone get their round bar stock to make intergrals from?
I love using W1 because of its wide variety of sizes. It's basically drill rod so it comes in every size you've ever found in a drill bit.
Fastenal is a good source, as well as McMaster Carr, and it's heat treatment is straight worward.
I like using 13/16" for integrals.
Just Google "W1 Drill Rod"
I buy both the W1 and the O1 from McMaster Carr in 1" rounds, 36" long
