I have several plane irons that I picked up that have nicks and dings in them so I need to grind a new bevel on them and I need some advice. I bought the Veritas grinding jig so I can square the blade which is easy enough but setting the bevel does not seem to work very well for me. The instructions say to measure the thickness of the blade based on the plastic gauge supplied that have lines every 1/8th inch and use half the thickness of the blade when the bevel is ground. The instructions then say to add 1 line thickness along with half the thickness of the blade on the gauge and then set the gauge on the grinding jig table my sliding plane holder. Then set the gauge so that it contacts the grinding wheel at the thickness described above and that should be the correct bevel. I wanted a 25 degree bevel and I thought I followed the directions closely but my bevel did not come out at 25, it was more like 35. I tried a couple of times and the same thing happened. Is there a simpler way to establish a bevel easier, I just bought a white aluminum oxide wheel that is 120 grit and I just want a way to set the bevel then I will use waterstones to hone the blade, any suggestions?

Set a bevel gauge to the angle you wish to grind at, place it on the table of the jig, adjust until it's at the correct angle to the wheel.
Regards,
the easiest way to get the bevel you want is to rip a scrap the thickness of the iron,then cut the 25° bevel on a saw. Place the template in the veritas jig, adjust the arc to this .Remove the template and install the blade. I have tried setting the angle with just a scrap of 1x , you need to rip the piece to the iron thickness to be accurate.

Mike,
I take a very simple approach. The tool has a bevel already present, right? Adjust the tool rest to the bevel already established by hand turning the wheel against the tool. Do this with the grinder unplugged and with a gentle hand. When the small scratches are at the center of the bevel, you have it set. I really never get too hung up on exactly what degree the bevel is. One or two degrees should make no difference, once it's there, you should never have measure it again.
