I have been watching a couple of threads on another forum. They are trying to figure out how to set a tablesaw to rip a 51 degree bevel. A second one wants to know how to cut a 60 degree angle. Maybe a little Geometry 101 would help them out?
Set the blade at —- angle to rip a bevel at 51 degrees:
Set theblade at —angle to rip a 60 degree bevel:

Bevel How?
On a rip cut with the fence or a cross cut using a miter gauge?
Geometry..
That would be with the rip fence. As in molding profiles. The one measurement would be for cathedral ceilings.
To determine blade angle on anything >45 degrees, subtract the angle you want from 90 degrees.
For your 60 degree cut, you would set your blade to 30 degrees. When you run the material, flip it up against the fence and run it vertical (flat on the table you get 30 degrees, vertical you get 60 degrees).
If I was going to do this, I'd attach a second board to the one I want the angle in with double stick tape to give support as it go through the blade. Otherwise it will want to drop as the blade cuts away the material because you are working above the blade. However you do it, use push sticks, etc., to keep yourself away from the blade.
I hope this helps,

Would a picture help
Perhaps I just have an old old saw, but my tilt gauge shows the tilt of the blade from vertical so a tilt of 30 degrees means the cut on the board is 60 degrees. Perhaps the new tilt gauges on modern saws are set to show the resulting tilt to the table.
We seem to be getting lost in words, so I include a diagram that is relatively clear to me.

Great Catch!
Peter,
Great catch!
Thanks,
Doug
Thank you
That was the diagram I have been trying to find. Makes a lot of cuts easier to figure out. Still just simple math. Anybody seen my protractor?
A few cuts
I made a few rip cuts with the blade flat on the table. Blade was tilted 15 degrees, according to the gauge on my saw. Took a protractor to the bevel, and.....it showed an angle of 75 degrees. A picture or two:
