Good question. After several years looking, the answer that comes back to me is always "no". I ended up cutting my own spindle and now drive it with a treadmill motor. While the setup works great, I wish I'd had a better motor... and by "better" I mean faster. Mine spins at 6700 RPM max. A 25K RPM one would be nice. One of these days I might just replace the bearings on my router and use that motor, which goes to 22K RPM, as the drive.
