New Drawbar For The Rockwell Mill - the penguin - 05-27-2017
If I can get the company leaves me alone, I'll actually get the mill, making chips.I've been out of town for the last 2 weeks, working on the installation of a new burner on a boiler and the fabrication and installation, of a new stack damper on another boiler, with 300 miles separating the two jobs.
Today, I was going to cut a 3/16" keyway in a 3/4" shaft, I went to tighten the ER 32 x R8 collet chuck and the drawbar stripped, the thread just rolled right off. So in the morning I'll make a new drawbar, I have a a 12' length of 7/16"-20 B-7 hardened all-thread, with that I'll have to make a nut assembly.

ended up being a simple project, an 11" piece of the 7/16"-20 B-7 hardened all-thread, a 7/16"-20 coupling nut, a couple of 1/8" roll pins and a quick plug weld and it was done.
