    Default Source for small, cheap bt30 spindle?

    Im looking to make my own cnc machine and I dont have the knowledge or desire to attempt to make my own BT30 spindle so I've been trying to find one online with little success (outside of a tormach spindle or unknown garbage from china). It may go into a pivoting head for a 5th axis so the smaller the better. Any leads?

    If you can find one, an old Emco Maier F1 CNC mill uses BT30 tooling for it's quick-change spindle. You could salvage one off that, but maybe not that cheap. These were good quality Austrian made machines, not Chinese. It would be fairly compact as well (it's a benchtop mill), and comes with a 1/2HP DC motor, running up to 2000 rpm, or could be faster if you change the pulley ratio.

    I'm looking to run 5-7 hp through it so it's gonna need to be beefier than that probably. Thanks for the response though.

    The ebay Brother spindle has everything OP needs. A Robodrill rebuilt spindle is $2500. lacks drawbar and everything else.

    Well excuse me for trying to help...... Not a Tormach shrill, but the OP listed 'cheap' first and foremost, I rather doubt several thousand dollars would qualify as cheap, so suggest that it is your skills at reading should be examined before casting stones!

    Any objections to a Taiwanese spindle? Posa and Royal are both established brands, and Kenturn is a younger company. A few months ago I got a few quotes for an a2-4 spindle from Posa and Kenturn. Both responded quickly and had good prices, ~$2k.
