Making timing pulley - putting theory into action

[wiatroda]

That's an actual drawing of my pulley
red circle is the pulley pitch
green - pulley diameter which i turned down after milling + filing to chamfer an edge
white polygon inscribed in circle of 11.2456mm



That's the way I did it, but if you have Gearotic it will draw you nice pulley shape- that's easier way, but for my curiosity and making my life more complicated I troubled myself with all the calculations :rofl:.
Hope it helps
