I'm barely even hobby level when it comes to CNC machining, and I do have a PM25 mill that's converted to CNC. I still have trouble determining what the best way to make parts is, and as an example, the attachment shows a pretty basic extension tube. If you had a choice of tools, would something like this be made on a lathe, or mill? I'm not looking for G code or anything that detailed, simply a very general "what process would you use" type of answer.
Thanks,
Rusty
