Its usually a problem measuring the helix angle without a print. Once you know the helix angle you want to make, there are computer programs that can calculate the gear trains required which will give you (or should give you) several gear trains to choose from (hopefully one of those solutions will have the gears which you have on hand). Other programs may ask you what gears you have on hand and give you a gear train for this. Bill should be able to give you a setup for this. The problem is finding the exact helix angle of the sample. Or you could make a set of gears, one for the sample part and one for the mate. I have not used my helical gear program for a while but it does keep your mind active. good luck
Are you making just one part or several?
