The latter is _most_ interesting, because the gullets can then freely be plunged with a slot drill from the side, and the tooth tips could be chamfered quickly with a larger diameter cutter. (Assuming that a chamfer is an adequate approximation of rounded corners.) > I have uploaded a 2D dxf of a 48T HTD pulley to filebin > <http://filebin.ca/vucjb/48THTDpulley.DXF>.

I'll see if I can find one of them on linux. (I see that it's a text file, but looking at that only tells me that there are lots of arcs in the pulley. :-) Erik -- Brahma said: Well, after hearing ten thousand explanations, a fool is no wiser.
