Thanks Tom.

If into crown cutting - some expensive sticks of crowns pay in a day
or less. Cutting custom boxes or angles on most anything and doing
it for a business - the real stuff pays and can be used to verify
a quality job later in a QA stance.

What you need is a "Precision Universal Bevel Vernier Protractor"

A lot of times you can find these in pawn shops.
Set this to the angle and align the saw blade and table to the blades.
A model 360 (non vernier) would be very good. Vernier version Is best!
New it was $250. Something like it in plastic and lower in precision
can be had at office suppliers. This one is rated at 1/12 degree with
vernier.

You nailed it, Martin. That's the kind of thing I was talking about.

Early on in this benighted thread I talked about using a protractor as a
tool to solve a problem which as the original poster posed it was to measure
an arbitrary angle to the precision of a tenth of a degree and make a
suitable cut. Machinists are accustomed to solving problems like this, and
consequently they have the tools to solve them. If a machinist gets an angle
called out as 70.6 degrees, he understands that he needs to produce an angle
between 70.55 and 70.65 degrees. He HAS to produce an angle to that
measurement and those constraints. This is a nice tool, Starrett as you
might expect, and well within the constraints of the problem. I have a
slightly less accurate machinist's protracter of my own, but I'm going to be
on the lookout for one of these. Thanks for the tip. I hope we don't end up
in a bidding war :-)

Glad to see someone here who doesn't have something to prove :-)
