This is a common issue with "some" sets of Renner parts, certainly 
not all of them. I had a set of shanks and flanges with excessive 
friction which would not go away. I unpinned all the parts, put a 
center pin one size smaller in all the flanges and sized the cloth 
with methanol and water. After the parts dried, I repinned with the 
same size pin that came out and the pinning was almost perfect, plus 
the friction problems went away permanently.

I don't know what causes this, but I see it all the time.

Good luck.
