Sir,
I could email you a copy of a page from Allied Devices, a company that
we used to use. They list oldham couplers. I gather that you are
coupling two different shaft sizes together. Maybe you could get an
undersize bore and increase it to what you want.

Regarding the steppers, are these 34 frame 600 ounce inch and 23 frame
260 ounce inch? There are a lot of overseas manufacturers who make
them as well as companies in the US. Do you need an exact size
replacement or what are your specific needs?

You can email me at
