Bill Stipe Model "B" Cam - not fitting

I recently purchased one of Bill Stipe's Model "B" cams for my '31 Roadster. I was already running with an older "B" cam (from Bratton's, I believe). Lo and behold, the cam will not fit onto the distributor shaft. The shaft is knurled at the upper end, which I believe is standard. It is a very tight fit, but hammering same onto the shaft defeats the purpose. Bill does quality work, so I was curious whether anyone else has experienced this problem.
 
Your talking distributor cam, I finally figured out. Do you have any other distributors that you can verify it is the cam itself? Otherwise I guess, you would call him up and return, or modify it to fit.
 
I've used a couple of those cams and never had a problem, never seen
a knurled shaft though.

Sorry about that. Yes, I'm taking about the distributor cam. Since I don't like to bother folks on a Sunday with business problems, I just thought the I would check to see if anyone else had experienced this problem.
 
I have never seen a knurled shaft where the cam fits. Someone probably knurled it because it was worn. You may need a new shaft or machine to fit the cam.

I pulled another '31 distributor off of the shelf to measure the components. It has a normal shaft with a diameter of 0.4665". The "A" cam had an i.d. of 0.466".

The "B" cam that I have been using on the knurled shaft has an i.d. of 0.4685"; the shaft diameter is 0.468".

The Stipe cam has an i.d. of 0.4645". It will not fit either shaft.

I will contact Stipe Machine in the am to see what their specs are. Thanks for all of your inputs.
 
It could just be an error. I bought a Stipe front pulley that did not fit, it had not been honed to size. Stipe was a stand up guy, said to return it, or have it honed locally and he would reimburse me. Some time these things just happen.
