It was or had been a steam locomotive driver lathe.? I don¡¯t recall for certain what the swing was.? But greater than 48¡±.? Alamo Ironworks in San Antonio had it.? My Father-In-Law ran their fleet maintenance department so I had seen it.? So during the run-up to building the Alyeska Pipeline, we had them machine some test defects into 48¡± OD X60 line pipe.? For some reason, I want to say that it was a 60x240.? I could just about stand up inside of the steady rest ? ? ? That was kind of a "medium" size boring bar. Don't remember the dimensions but probably 8" diameter, maybe 6 or 8 feet long with a #50 taper. Can you see a series of slots? They're for the cutting tools themselves, indexable carbide inserted, made them too. We made 3 or 4 different sizes, those would have been 1" x 4", some adjustable and some fixed. The large hinged part is a support for the cutter, clamps on the bar. That one might have been for a 30" diameter hole! Biggest one I ever made was 10" diameter x something over 200" long. Boring crankshaft journals for Electromotive. Feed the bar thru, get everything aligned then a guy would get inside to put the tools in the slots climb out and bore. Safety first! I guess. Glad I don't work on big stuff anymore. ? Dave ? On January 21, 2019 at 6:54 AM Jody <jp4lsu@...> wrote:

Were you measuring the OD or what?
