I laid out $99 for the sharpening rig from Powertek. But now I am too cheap to buy the raptor angle templates. Does anyone know how to set up this rig for grinding specific angle? If I understood the geometry I could make a template but there is a tool holder that needs to be set as well as the distance from the wheel. My grinder has 8 inch wheels if that matters.

I am trying to grind a bowl gouge and I have already messed up the grind trying to free hand it.

Look at Capt’n Eddie Castelin’s YouTube channel. He has drawings and a vid about a grinding jig that you might like to make for almost nothing. I built one, and use it often.

See if you have a local turning club. Members are more than willing to help.

Hey thanks. I have seen his jig. How do you set yours up for the proper angle?

Your system looks like a One Way Wolverine sharpening jig clone. See instructions below!

Really need to know the bevel angle of the tool you have to start with!
I use two school protractors with small bolt & nut in the middle of those protractors to measure before & after sharpening. For just a few bucks at HD can pick up a steel protractor does same thing before and after grinding.

Some folks like these angle checkers.

John Lucas made his own raptor guages.

So how do you set up your sharpening jig? Take a look at these Wolverine instructions. This will give you a great starting point. Never saw a need for raptor gauges, learning curve for me was pretty short following instructions that came with my Wolverine.
