TOY: Re: Toy Gear Ratio

[Steven Keene <stkeene@xxxxxxxxxxxxxx>]

I guess the basic answer is devide the ring gear teeth by the pinion?  I 
didn't think it was that simple. Partly because I was confused by the 
answer I was getting by doing that.

Anyway, I just went out and triple checked the count and it was actually 
39 on the ring and 8 on the pinion.  (Had Girlfriend write down number 
while I cleaned up.....)

So that's 4.875 ??  4.88's 

Next question. Since I'm replacing the rear and not the front.  Is there 
any danger in mixing different manufacturers gears, front to rear?
