Anyone have any idea where I can get a ring that has the 360 degrees marked
on it? I need one to make a miter base. It needs to be about 12" in
diameter, and if made out of metal, that would be nice. Is there any
companies that make these? What is the precise name for them?

Got a rotary table or a dividing head? If not it's a good excuse to buy
one and then you can make all the degree rings/dials/knobs you want.

Don't know about a "ring" but if you want to cut the center out you could
make one from a degree or timing wheel. They're on eBay (of course).

You could make one as follows:
Make or aquire an aluminum wheel (say 1/2 to 3/4" thick) with
appropriate bushing/shaft.
Make epoxied paper scale to wrap around, and fasten to, the periphery.

For details on making a precision paper scale, see

and associated photos.

They are called Circular Protractor.

I have seen 6-8" diameter sizes - Starrett has 7" Precision Universal Bevel Vernier Protractor.

I'd try 1. An office supply - real one with drafting... not big box. Big Box web page maybe...

Professional Protractor at a machine shop supply house.

Save your self some trouble, and go he

you can print out a number of useful graphs/grids, and it's easy as pie.
Polar Graph paper is around half way down the page, and configurable to
print as many lines as you may like.

Graphing and charting came into life with excel use - prior to that xero booklets
and buying sets from local stores.
