Saw's Bevel Gauge
Most saws have a basic bevel gauge built in. Often times this is below the saw along the rocker. A simple needle points to the gauge marked on the rocker to indicate the angle. My scroll saw has a gauge built into the table, which makes it easy to see. This is a good way to get in the general ballpark, but not very accurate nor repeatable. Use this gauge if you don't need repeatable angles, or if accurate angle isn't necessary.
Protractor
A simple protractor is an easy way to get an accurate reading. You can pick one up for a couple of dollars at an office supply store. Make sure you buy a small enough one where you can lay the protractor against the blade. Line up the bottom of the protractor to the center mark, then adjust your table to the appropriate angle.
Paper Protractor
I like using a paper protractor. Download this paper template here. Use spray adhesive to attach it to some 1/4" plywood, then cut it out with your scroll saw. The nice thing about paper protractors is you can write on them. Use a red pen and draw a straight line from center point to the appropriate angle. Then simply adjust the table and line up the red line with your blade. You can also write notes on the protractor for each project (IE Bowl. 20 degrees for 3/4" stock.)
Digital Angle Gauge
I use a digital angle gauge. I picked mine up for about $30 on Amazon. This is super accurate, getting within 1/10th of a degree. You turn it on, place it on the bed of your scroll saw, then push the "Zero" button to zero out the gauge. Then you can start tilting your saw until you get your exact angle. This is my favorite method. I also love being able to use the gauge on other tools where I need an accurate angle. The magnetic bottom will attach to a table saw blade as you tilt the blade.
Smart Phone
Phones now days are amazing. They even have a built in angle gauge. I usually have mine within easy reach and it's very convenient. I use the iPhone, and the gauge is listed under the "compass" app, which is pre-loaded on your phone. Swipe to the left to get off the compass and onto the angle gauge (level). Place the phone on it's edge, then tilt your bed. Be careful to keep a hold of your phone. You don't want it to slide off onto the concrete floor (I won't tell you how I know this). This is super convenient. The only draw backs is your table has to be level with the floor to begin with (no zeroing option) and it only measures to the degree, not a fraction of a degree. I'm sure there are other free apps that address these issues, but the built in app works well enough.
