[joecnc2006]

Joe I must applaud you on not only building a 1st machine but also a 2nd!!!!!!! man you don't hang around. When making your'e own machine would you recommend building the basic structure 1st ie just basically the frame and then getting leadscrews, motors etc after or do you get all the materials 1st and then make the frame to fit??? It puzzles me of what is the besy way to go any help is always very well appreciated. Laz.

What i do is see the parts that is most available and easy to get then build a machine around that. For example the standard lengths and standard thread and pipe dia.

Added two springs tothe Z Axis to act as a counter balance so the motor does not have to work as hard to lift the tool.

Looks great Joe,

The springs are an original idea.

I am also starting the build of my second machine. It will look alot like yours I think. I have finished manufacturing the parts out of nylon and bought my sheet of 3/4 MDF today. I am planning how to cut all the pieces out of the 4'X8' sheet. My first machine was the JRGO and my second will be a decendent thereof. Keep the pics coming!!!!

Aren't you going to get a lot of flex with those long unsupported pipes?

I will see once it is finished, if so i can add a suport on the interior of the pipes.
