HokieKen - I'm thinking a piece of walnut might work.  Will have to see if I have anything else.  

Already have a sharpie ready to take out to the shop!

Corelz125- not sure if my expectations are off.  I expect a consistent depth of the abrasive on the bevel from the start. Right now it seems to start showing on the left and only after some time does the abrasive shift right, and start to even out.
