Calculate Error from uneven rail and reference

[John McNamara]

The weight was a 4140? 200mm dia gear blank 35mm thick I never did weigh it by calc about 11kg

Roslau blue label carbon steel wire is not transparent?

The lathe if you are referring to that works fine I use it every day. Not perfect but near.

There is a picture of Heidi in this old paper I wrote when she got her referb.

thx. I will follow your approach then. The wire on the photo just appeared to be transparent.
