Drill bit web thinning.

Thanks Tony for the post,
I bought a similar grinder off the internet that was so off from one side of the chain to the other I have started to make a small sort of all purpose grinder from it. I bought it to true up old chains to ring every last drop out of them but I can do better by eye than it could do and what is the point of trying to reset for each side I figure. Seems I will be able to use it as a sort of tool post grinder on the lathe also. Have found the narrow grinding wheel is helpful for some tasks as you clearly show in your post.
