Hi Bob,
I have to admit I didn't use the plating for the backlash.  Most everything I do is on 4" by 5" mounting board.  I will space the "set" so that its relatively centred on the mounting board and then drill a 1/8" hole for the first shaft.  I mount that gear and then with a sharply pointed steel 1/8" punch I find where the second gear will rotate sweetly and then punch the center point and drill it.

I probably should use the plating page and get the backlash correct.

The shaft spacing although empirical was controlled by one tooth on the "straight" portion of the gear.

>>Program seems to 'dawdle' while creating the gears.  (I should be paid extra for using computer terms like 'dawdle'.... aka.. hangs)

  That can happen, but it will eventually finish. If the "extreme" resolution is selected it can take quite a while
as its actually shaving the gear very slowly around the blank. If you cant generate it, the drawing cannot be put
out, but  I will look into a way of getting that out as a dxf..I can see where massaging it woudl be much easier
than trying to find one that you want but canot generate..
