The left menu has links to some pictures and stuff relating to the build.
There are so many people to thank for their help, suggestions, and ideas for my machine.
Some may disagree but for me a belt drive is the way to go if you are
considering building your own machine. I am not able to measure any backlash and
the speed and power is more than the 1 1/4 hp. Bosch router or a 1/4" end mill
If you have any questions I would be glad to do my best to answer them, just send me an e-mail.
The CNC Zone message board for the greatest help and suggestions anyone could ask for.
Whether you build your belt drive machine or go with a set of tried and true plans, David K. Steele's CNC Router Plans are a must.
