    Bump Bump for/ Re/ Questions

    O.K. trying to make a spindle here need some help. I saw an image recently that got me thinking. It was of a d.i.y. spindle made with an r.c. helicopter motor. In this image the spindle shaft was an extended ER 11 collet chuck that went thru the motor. Is that at all a real possibility, or was it wishful thinking?
    If, I need to pick a d.c. motor, what should I be looking at and if the r.c. motors will work what about those should I consider? Add these things to my question list.
    I know it's a lot to ask but I am sooooo confused at this point I'm going bald just web searching and searching and you get the picture.
    HELP, please

    Just my opinion, but if you have to ask these questions, then you'd probably be much better off just buying a spindle. I certainly would never consider building a spindle myself.

    The first and possibly the most important though, it is far easier to buy a decent spindle than it is to build one without a well equipped shop.

    How will you power that motor?

    In industry it isn't uncommon to press a motor shaft out of a rotor and install a custom shaft. However this is not a trivial task.
    If, I need to pick a d.c. motor, what should I be looking at and if the r.c. motors will work what about those should I consider?
    First off I wouldn't go the spindle integrated motor route. If you avoid doing that you can belt drive you spindle from a number of different motors to suit whatever need you have. In any event I wonder why you would buy an RC motor rather than an AC or DC motor in either metric or NEMA standard frames.

    Understand what I'm saying here, there is an easy way to a spindle setup and then a far more involved approach. To integrate a motor rotor onto a spindle is the far more involved route. An integrated motor might have some benefit but if you need to buy an entire machine shop to build it, what is the point.

    Add these things to my question list.

    I thought you already built a spindle?! You can buy a Chinese electric spindle for the price of an RC helicopter or plane motor! Or just buy a Sherline or Taig spindle and add your own motor (you can buy it with their motors too.) There's a guy on eBay that makes Sherline spindles up to ER40 collet. Sherline even makes spindle cartridges if you want to make your own spindle head or housing. Maybe a description of your planned usage would help!
