Re: Need help with gear ratios
Thanks for the reply, I guess what I really need to know is what would the 1/14 scale rpm of the swing be on a cat 320b, from that I can work out the gears needed.
Thanks

Re: 1/14 Grader Caterpillar 12F
Absolutely great precision work, you are a talented man. I really like your cnc build also, did you build it from a plan, if so I would love to know where I can get a copy.
Thanks
