Ed,
It sure looks like you are ready to write the first review/tutorial.
If you have time to do so, please submit to Doc and the rest of us (owners) can use yours as a format. My original plan was to give each participant an outline, but I suspect you don't need one!!:laugh:
The other part of my "Plan" (which is certainly subject to change - if you wish) was to have each person use one gear configuration. It appears each of these was done with the same gear ratios. To keep it simple, if you WANT to, show all the things that can be done, without changing those gears.
Of course, you CAN do anything you like, this is just meant as a friendly suggestion. Hope you will write something, tho- it would make a great "starting point"!!
