I've been looking for a good excuse to get a set of small files, so I guess this is as good an excuse as any. :) Unforch, when I went to MCMastercarr, they have no 5mm HTD stuff under 15mm wide. I think I could machine away that cover to make room for it though since there aren't any change gears doodads any more. This belt seems to be a 5mm pitch belt, just with cogs that aren't near deep enough to move the power. That belt is 70 cogs long, but the small end pulley is 17 cogs. McMasterCarr only has them in even numbers. I am tempted to get an 18 for the lower, and I've forgotten the upper count but 30 seems to come to mind. And they only have belts in 10 cog increments. So the shaft would have to rise 2.5mm. I think that is doable. The limit is that it needs to be level, and there is only so much room for the 3" polygroove pulley on the other end. So I'll order 2 15mm belts, a 30mm? for the top pulley, and 1 each of 16 cog's and 18 cog's for the lower one. Monday. And I need to repair 2 cables that got pulled from the terminals while I was wrestling the toolbox its sitting on out of its assigned space, which gives me a good excuse to put in some cable/chain I bought for the carriage stuff. Those are always getting hung up on something it seems. By the time I eat whats left of the repaired 17 I put back on yesterday, I might have the polygroove pulleys for the mills spindle made. Maybe.
