I’m a professional sharpener, and I use a paper wheel for all knives and to hone broadheads. Before ABS started marketing the paper wheel, Ed S. asked me how it worked for me. I told him I buy them from Woodcraft Supply and use their slow speed grinder(1700 RPM),configured to turn away from me. I never use the gritted wheel, replacing that with a buffing wheel. Instead I use a 1 x 30” belt sander configured to turn away from me(ALWAYS!!). The sander uses 800 grit belts. For broadheads, I grind with a Tormek(Swedish machine, too expensive for most home shops), and hone with the paper wheels.
For safety’s sake, always configure your machines to turn away from you. Even at that, if you screw a broadhead into a shaft and use too much pressure on the paper wheel, it can loosen, turn, and be thrown into the wall behind(trust me on that!) Don’t worry about reconfiguring the grinder, just turn it around and remember that the switch is on the back!
A jig is really not necessary if your wheel is turning away from you. Apply plenty of sharpening compound. Hold the broadhead perfectly horizontal(it BETTER be mounted on a length of shaft!). Top dead center on your wheel is a zero degree bevel. Right smack at your bellybutton is 90 degrees. 45 degrees is halfway in between. 22.5 degrees is half-way from there to the top. Take a flexible ruler and lay out the degrees on the top of the motor where it is in your vision when you sharpen.
Then, just practice. You can make a glass smooth edge with a paper wheel on most any un-serrated blade, once you get the feel of it. This isn’t something you take to the field in your pack, but it’s sure a good way to start off!
