Bookmarked & printed, just what doc Gene ordered, thank you very much Gregg. Now, I have 1/2" of pulley width for each pulley section. From those drawings, that infers that in 1/2" I'd have room for 5 ribs of a "j" belt. That would be 15/32" wide, or in metric, 11.90625mm wide. That would have sharp outer pulley edges though, so I am inclined to make and get the 4 rib versions leaving a relatively wide outer edge. The next consideration would be the smaller pulleys reduced radii, and belt heating when its wrapped around a 35mm pulley. Not to mention spindle bearing heating. When in the step up mode 5k revs is going to be close to 10k revs on the smaller pulley & bearings. I assume that has to generate additional heat in the bearings. With the diameter of my starter steel, the flange for the draw and jack bolts is not going to leave enough real estate, determined by the results yesterday. So I'll have to find larger OD piece of shafting for the raw starter. This one now has too big a center hole drilled for a taperlock to fit an 8mm motor shaft I think as the last drill before I tore up the wiring was a hair under 10mm. So that one will not be salvageable for the motors hub. There is however, more steel sticking out of the chuck. I just need to make even more swarf. :) I should have a bigger piece in the midden heap on the floor under the shelf that holds the keyboard etc for the mill. If not, I know exactly where to go & get it. But it is about a 100 mile round trip, over some roads that would break a snakes back. This is after all, West Virginia. We have a surplus of hills they built the roads "around". Thanks Gregg. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
