Dave. I don't normally respond to new builds as I am a newboy myself that has been guided through the maze of do's and don'ts of building and buying different parts for the machine and now after a year of hard work I have succeeded in building a router 1600x1000 that I am happy with. I have only been able to achieve this without wasting a lot of money and time with the help of Dean (Jazcnc) and Jonathan form this forum. They have given there time freely you cannot buy that sort of experience.

Why don't you start with a drawing in something like Sketchup (its free) and post it on here and then the good people will evaluate it and give you good honest feedback as you develop it into a working drawing and then a machine.

As you are doing this they will advise on the type of motors, drives and rails etc that will work with your setup.

It would also help others if you said what you would like to cut and to what tolerances. Please take this with the spirit it is intended and good luck with the build. ..Clive
