Are there any downloadable programs (freeware, etc.) to construct gear / chain / belt configurations? I would like to be able to monitor rpm, timing, etc. through the entire setup.

Do you have any familiarity with Excel? All a program would really be doing is multiplying or dividing by ratios, which you can set up in Excell pretty easily.

Take a look at GEARFIND and GEARATIO on my page. They're aimed at this problem
and free for the downloading.

JDF, I have done excel, but I didn't think of it until you mentioned it. I'll try to come up with something when I have more time.

John, The current project is relativly simple. I'm trying to time a magneto on a one lung hit&miss engine. The pulse of the mag does not stay in time with the position of the crankshaft. I'm wondering if the mag gear has the correct number teeth. I would like to experiment with different numbers of teeth. In the past I've done this type of figuring, but only on paper. I've built machinery where everthing on the machine was powered from one main drive unit while separate drivens were branched off by belt, gears and chains to obtain the correct surface feed to different diameter drums, rollers, etc.

Marv & Evan, I knew this was available, but didn't think of it. I loaded up on Marv's zip files. At least I'll know where it is (for now).

Thanks for the info,
