There seem to be many options to do this so no harm asking for what you guys use / recommend. Scenario you are told to mount a piece of metal at 15 degrees in the mill vice...which tool do you use. To date just been using an old school protractor but you can get stainless ones with attached straight edge also digital levelers etc?

How accurate do you need to be. I use a steel protractor with an adjustable rule for general use and have a few pieces of gauge plate with included angle on for better work but use a sine bar to accurately set pieces which must be right.

Digital bevel gauge does everything I need. Works on car suspension too.

The digital ones are good comparators just check the bed then the work

Is that 15, 15.0, 15.00 or 15.000 degrees. There is a difference, and method of measurement should undoubtedly reflect this. I actually tilt the vise if the angle measurement is not approximate. It may also depend on other factors, of course.

You have a wide selection of methods.
A Digital angle gauge; a Digital Protractor; a Vernier protractor, a metal Protractor, with either a round or a square head, and Angle blocks.
Each has it's advantages and disadvantages. From time to time, I have used almost all of the above.
Choose whatever best suits: the work that you propose to do; and your budget.

Examples always help:
When milling my favourite angle tool is a Rotary Table. I also have a Swivel Angle Table, or grip work at an angle in the machine vice, or bolt it direct to the table with blocks to control the angle. My swivel angle table gets least use, but it's really handy for some jobs.

Swivel the table! and then check it with a gunlaying clinometer.

All depends on the accuracy required, a cheap plastic protractor up to a sine bar.

As others have said, it's really a question of what accuracy you're aiming at. A sine-bar and gauge blocks is probably the ultimate, but how accurate is base on which the sine-bar is referenced relative to the mill spindle? Pretty good results (to about 0.1° can be obtained with a digital gauge (Wixey?) that is zeroed on the mill table or vice, then used to position the workpiece. An error of 0.1° at an angle of 15° is equivalent to about a 6 thou error in the gauge blocks on a 4" sine-bar.

Funny you should mention a cheap protractor Baz, I have ordered in amongst a couple other items a zero edge one as this has some benefits.

Yes, but given a gauge set has tenths accuracy there's no excuse for making 6 thou errors with it!

For"standard" angles I usually find a set of these makes it easy:

I agree with Bandersnatch. The setting guages are the simplest solution to most set up's. I have never had to resort to anything more sophisticated. No doubt having said that I will now need to.

Good recommendation, I have the same set, very handy. Arc sell that set too, but for less

Over the years I have made a set of angle setting "Wedges" from 1/4 degree to 50 degrees. for most work they are good enough. I do have 2" 3" and 5" sine bars but they are only used occasionally.

Like others I have a couple of ways of setting angles; Stainless protractor with pivoting straight edge, Digi gauge, M & W protractor /rule, plastic protractor ( from school pack ). Using the digi gauge I always set the zero relative to the mill table. I have since made a set of angle gauges using trig' some previous write up a member had written up ( can't remember where ) & checked relative to the Digi gauge, all within +/- 0.1* which is more than acceptable for my use. I would like a sine bar, but would I use it... probably once a year, if that . a couple pics of home made set ...
