After spending a week with Charlie Lewis in his shop, I've been doing a lot of thinking about belt grinders.

While the 2 inch belts can do the bulk of the work, there are some things that seem to do better on a 1 inch belt. Since it would be a bit premature to be planning my second grinder before getting the first, I am wondering if one grinder can accommodate both belt widths.

I know that I have to use a 1 inch contact wheel, but would like to know what else would have to be swapped. I'm thinking that the drive wheel could remain but am wondering if the tracking wheel for a two inch belt would also work for a 1 inch belt?
