Tom,
Your initial stated problem had a motor pulley diameter of 1.0. This was not one of the pulley diameters on your spreadsheet. If you rearrange my formula to LP=(MR x MP x CPL)/(CPM x LR) and plug in MR=3450, MP=1.0, CPL=5.0, CPM=5.0 and LR=1725 the formula will look like (3450 x 1.5 x 5) = (5.0 x 1725) = 2 inch lathe pulley diameter. I did not have time to work on this until tonight. The formula looks correct.
