Thanks zeeprogrammer and Kim! I am very pleased that you like my build.Next 4 pcs eccentric sheaves were turned of 16 mm mild steel bar. There is nothing special with these turnings but to drill the offset hole. Of course I could have made that in the 4 jaw chuck, but somewhere in Internet I had read that it is possible also in the 3 jaw chuck, to put a packing under one of the jaws. This method was quite new for me, so I decided to try that.There are at least two formulas to calculate the thickness of the packing:Simple formula: Packing = offset x 1,5More accurate formula: Packing = 1,5 x offset x (1-(1/8x(offset/bar diameter)))Calculating after the first formula, I got the thickness for packing 3,49 mm, and after the second one: 3,57 mm.I selected 3,5 mm to be the compromize for me and made a brass piece of that thickness in the milling machine, put that under one jaw of the 3 jaw chuck and started turning. I think it succeeded quite well, resulting to the wanted offset of near 2,4 mm.So now the eccentrics are made, but I have no idea, how they must be adjusted to get the timing right. There is nothing shown at the drawing. I wonder if some of you might be able to help me.
