CNCDevil, Please do not think we're being overly critical, we're trying to be helpful.
The method you propose has been discussed before and pretty much abandoned. But who knows? You may develop a better mouse trap!!!!
Regarding "spindle"; What you are referring to as a spindle I would call lead screw bearing seat. To me a spindle is either a work spindle like where your lathe chuck is attached or a cutter spindle where an end mill is attached. I suppose it's a local thing. lol
Proceed as you wish. Just for fun, keep track of time/cost and see if you actually meet your objective at what cost.
Good Luck!!
