I have two dxf files that someone from MI emailed me two years ago and of course I can't find his email address or his name. So, I have two files and I will see if I can get some cut at work and see how they work. But, if they work maybe I can get some different ones cut also. Any ideas? And I don't have the sled at home, can someone measure how thick the big gear is? I have the quick change hub from Rec Motors and they are made of alum now and I will also make them out of alum.

If someone has any ideas, I open to anything.

Thanks!

I will go grab the vernier and measure the sprocket on my quick change hub.
