Bob A friend got what she thought was a great deal on some D-A track hubs on Ebay. She didn't realize there was a problem till after she'd built a nice set of wheels around them.

Thanks to the internet I was able to hook up with a CNC machinist who made her some 1/2" pitch, 33mm x 24tpi cogs. His price was very reasonable, for custom work, and he's kept the CNC program. Don't know if he's still in business, but a year ago he said it was OK to pass his name on to anyone needing such cogs.
