I tried wrapping both tape and paper around the turning, but being
convex and tapered, it just wouldn't lay flat. I tried auto striping
tape which will follow the curve but when I removed it to mark out the
segments, it had stretched into a very curved shape which was difficult
to measure with my straight rulers.

Any simple ideas to help out?

Tips fer Turnin': Place a sign, easily seen as you switch on your lathe, warning you to remove any and all rings from your fingers. Called degloving, extended hardware can grab your ring and rip it off your finger. A pic for the strong of stomach: http://www.itim.nsw.gov.au/go/object...6BFC/index.cfm

Besides, rings can easily mar the surface of a turning as you check for finished smoothness.
I have an exel spreadsheet that will give x and y co-ordinates for points on any pitch circle diameter for any selected number of divisions. With this you could calibrate your face plate for this job. If it of interest e-mail me Tony Ashgrove at
