    Hobby CNC

    Anyone made a 2 or 3 axis (or 4 or five for that matter) CNC/dremel type router ??

    check out CNCzone.com

    You can get them so fine tuned and with resolution so much that you can get photographic results:

    http://70.85.87.12/stepper/Gallery/gallery.htm (look at the top link)

    ..not to mention that you could make/repair camera parts with one

    I am investigating making a motion control system for cine work (and long exposure stills) and in turns out I am going to be using the exact same stepper motor system as the people making these routers so might make one also to get double bang for my buck ...

    interested if anyone else has seen or played around with it
    Cleared the bowel problem, working on the consonants...

    Dave you would want a lathe for that, not a mill or router (same thing). There is a sherline CNC lathe big enough to do instrument mouthpieces for about $2300 at

    http://www.sherline.com/CNCprices.htm

    These are tiny lathes, but if all you are doing is mouthpieces, they will work fine for you.

    Very tiny boring bars from Micro 100.

    And for the outside turning you would use standard high speed steel or carbide tool bits

    I'll look into this,

    the throats and backbores are tapered and different that the outisde, which for trumpet is a morris..would be nice if a small shop set up would be possible for custom work etc...

    I have decided to use Xylotex 269 oz/in stepper motors and 4 axis driver box. This will be used with a 3 axis ballscrew kit from CNC Fusion to convert my Grizzly minimill to CNC. Does anybody have any experience with these retrofit parts?

    I have no experience with a minimill, I have one of those monster benchtop mill/drills (that weighs ~700 lbs.) However, within reason a larger motor and better drives will give you much better long term performance. I usually use a 34 frame stepper, more bang for the buck, in my experience, but you may not be able to fit that on your machine. The only drives I have used that have been absolutely flawless have been the Geckodrives. Top notch product and top notch support, Mariss is an example of how to run a small business (and he's a pilot too, always a plus in my book)
