beginning steps to building my cnc

[scnc]

Hi all,

I have attached the beginning steps to building my cnc machine. I hope to make it approximately 4x3 or 5x3 foot

Attached is the image of the metal fabricated framework, with brackets on each corner which will house the plyboard bed. There will be no top and bottom framework but only on the sides, in order to allow full sheets of boards to be cut continuously hopefully if this can be achieved). If there was framework on all four sides I am limited to that bed space. Is that right?

Also Can anybody give any clues about what stepper motors, ball screws, router, belts if i need any? bearings, tracks, brackets and drivers I would need?

How long would it take to make? and how difficult will it be?

I do think the best way would be to get someone to build it for me.
