Can anyone suggest a brand and source of a good digital protractor for
precise measuring of angles for segmented turning?

Actually no. I use math, a digial micro for length, a CMS and finish
with a disk-sander that has a tuned slider-table-stop block.

I don't think there is such a thing, short of tools for setting up space
vehicles. We have tried some of the digital levels on the market,
and they do READ to nice, sometimes high degrees of accuracy, but,
unfortunately, they aren't really that accurate. Get a sine bar.

Greg you can get Vernier Protractors which are very accurate and should give
you what you require?

Greg put "Vernier Protractor" into Google Images and you will get many
pictures etc.

Gimmicks are all we long-term tool collectors have to acquire now, and this
one seems promising.

Or this one to calibrate the saw that makes the jigs.

See Arch's measurement post. It's not the measuring that counts, but the
doing. You have to make a machine as capable as your measurement device to
make it worthwhile.

Greg,

You can buy a reasonably good dial bevel protractor on eBay for $19.95, similar
to eBay's item number 140170927217. I bought several different kinds of bevel
protractors and have found that this one is the most accurate and easiest to
use.

This type uses a dial scale rather than a vernier scale. The dial scale reads
in degrees and minutes so a calculator is handy to convert minutes to decimal
degrees and vice versa. The smallest scale graduation is 5 minutes, which is
..08 degrees.

I have an article on my website about bevel protractors and the minutes to
degrees conversion: http://www.turnedwood.com/techniques.html

If you buy one of these dial bevel protractors, it's a good idea to check the
protractor against a good square to see if it needs to be calibrated (or
returned if it's really far off).
