Congratulations. Excellent work and it runs beautifully.

No "degrees" used due to it being an absolute scale. Apparently.

Welcome to the group musterpilot. Enjoy the new lathe. What is the glow engine by the way?

I know these as Stevenson's collets. I use a depth stop on the vice to allow "same position" rotation. So far, they have worked well. As you say, quicker than a dividing head for basic jobs.

Soft correction purely for clarification. "the brake and clutch fluids are above their flash-point, so instantaneously ignite. No spark, flame, etc, just a spray of fluid onto pure temperature of hot metal... And the spray ignites." In the above analogy, the correct term is "ignition...

Went to the show this morning to buy some 1.5", 1" & 5/8"ally round bar and also bought hex ally bars, all from Nogin. Picked up a 4 1/2" angle plate from RDG. Great show, despite the weather (lots of snow). Took some pics: and copper boilers (at a price)! Worth the trip and...
