Digital Protractor for Segmenting 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:

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).
