Re: Tread Spacing on the TTS [TANKS]

Cool, what are your plans for the tracks and sprocket?  I couldn't get 
emachineshop to quote me anything less than $150 for the sprocket, so thats 
out.
I think if you're doing a sprocketed system, you want to start with the 
sprocket and let that guide the spacing (perhaps thats what you meant with 
"now for the fun of the track"?)

Take care,
Amir
