Never thought to use a pencil for a dowel,good idea! Looks like the first one turned out great,good luck with the others. I've done one grind to fit in the past and will have one to do here before too long. I don't have a grinding jig,but I do have a 1" piece of buttstock that I cut off another stock. I may try to improvise a grinding jig from that.
Good job!
