Bear:
Thank you Crueby for the excellent response. By the way, what second lathe did you get for threading?

My main lathe is the long bed version. For threading I  got the short bed one. You can buy it a bit cheaper without the motor since the threading doesnt use it. I did get the motor since it wasnt much more as part of the package, and I  needed a spare one soon after so it was a good gamble. I put a LOT of time on my machines over the last 20 years, and wore one motor out. Had put in new brushes a couple times but finally wore out the commutator ring. The newer motors dont have replaceable  brushes, will find out in ten more years how long they last!

Bear:
Thank you again Crueby. I missed the Sherline November 20% off sale on lathes. I am very tempted to try one. I remember they used to have discount codes a while back. Anyone aware of any for the lathes?

I don't see any problem doing a cylinder like that on the Taig. I haven't done any quite that size, but have done several steel cylinders 0.75" bore by 2" that came off the lathe straight and smooth, several others slightly smaller. I like to make a close fitting plug gauge to check that the bore is straight, and if there is more than one cylinder, that they are consistent.

I've also turned 1.5" diameter locomotive driver wheels in steel, and flywheels up to 3.5" (that one was cast iron).

Bear:
Thanks Ron. Very encouraging.
