hey guys, I was hoping you could answer a few questions. I've never used a CNC mill before but it is always something I've been interested in and would be a natural extension of my welding and metal fabrication.

-How do you price jobs? Is there something similar to cutting and welding where you price the total cost of the material, then per inch of cut/weld? Or is it all in the amount of time needed to run the part and the material cost?

-Is it really feasible to learn to operate a machine based on the Tormach workshops and youTube? I saw the book thread and there looks like some good recommendations, but are they really geared for a novice?

-If this turns out to be a terrible idea for me, what is the normal sale price on a used machine? 75% of the new cost? It seems like they are selling pretty quickly.

thank you all for your time.
