    Hi-

    I recently picked up a 68 Schwinn Racer and googled to find some information on the shifting mechanism because mine doesn’t seem to work and I would like to restore it. (That is how I found your blog) I don’t understand how it works because there are no chain rings or cogs. Is the mechanism on the inside of the hub? Any light you could shed on this mystery would be ever so helpful! Your bike looks super! I am so looking forward to getting it on the road! Thanks! Kim

      Just look up Sutrmey Archer 3 speed and you will find all the information you could want. Sheldonbrown.com is also a great resource. If it shifts, you don’t have to do anything to it!

      It uses an internal geared hub. Look up “Sturmey Archer 3 Speed”.

    I have an emco mill just like the one you purchased. It is all orginal and works great but I would like to upgrade/retrofit and possibly add a 4th axis. Can you tell me what components were used to retrofit your mill? Steppers, drives, VFD’s etc.

    Your help is greatly appreciated.

      I bought it from someone who converted it – less work for me. I had a Gecko driver and a standard 1/3 hp vfd. New steppers and a power supply. It was a basic conversion. O still haven’t gotten it to full operating condition, but a usb smooth stepper may be next. The reason is that you could use any PC, run it without worry because latency to the parallel port will not matter anymore.
