That doesn't hit it exactly but a search for a 384K3, which would be 15.11" comes up with a solid hit. And from the drawings the 3.56 mm spacing says I can put that on a 1/2" wide pulley rim with a bit of room to spare. Their sort by title is busted, it starts with 1000khuge and works up into the 300's about 17 pages in. :( They do not say, but I have to assume the 384 is the length in mm's. And at $3.16/copy, thats certainly affordable enough to buy spares. I think I will have fun grinding the rib profile on a cutoff tool bar to make it though, that is a quite narrow included angle, with lots of material to remove at the bottom of the rib. But I'll have to call them Monday to get the rest of the measurements. Unless someone here has a copy of the "K" profile they can share? Hint hint. ;) Probably better off in terms of z flex on that thin cutoff tool, to set up the right angle and do one side of a 1/4" tool to half that angle. But that is not todays job, making the OD of the first taperlock hub is. ;-) > On 5/2/2015 6:31 AM, Gene Heskett wrote: > > On Saturday 02 May 2015 05:30:56 Erik Christiansen wrote: > >> On 01.05.15 05:55, Gene Heskett wrote: > >>> If the larger pulley is 70mm, thats nominally 110mm of wrap, and > >>> the smaller pulley is 40mm, thats 62mm of belt wrapped, and the > >>> shafts are 100mm apart, I'd have 110+62+200=372 to 380mm of belt > >>> needed.
