Keith asked:-

> How did you measure that 3 degree taper?

I didn't.  I machined it.

First, I set the compound slide cutting parallel - this took a little time, 
but I only had to do it once, which when I commissioned the lathe.  Then I 
noted the error on the degree scale, which was 1/4 degree clockwise.  When 
setting the slide, I allow for that error assuming that, the machine being 
British made, the graduations had been engraved accurately.

After that, it's all down to eyesight and craftsmanship.
