[CAUT] Fwd: Does V S Profelt work in reverse?

[David Ilvedson]

What is the difference in European/Renner center pins?   They must be metric...does that mean they are in between our centers?   I OFTEN find a new centerpin will be just tight in the birdseye and very tight in the bushing.   Or tight on one side and Ok on the other.   I'm repinning everything.

Hi Debbie, 
Did you suggest that you can successfully increase rotational friction on new action centers using VS Pro felt? 
I would like to know more, if you don’t mind sharing.
As mentioned, new shanks/flanges often have less than 1 gram of friction
or they appear to have 6 or 7g, until you merely mention CLP in the vicinity, then suddenly they are down to 0g. ;>) 
And this is when you discover that the #20.25 center pins (.5025”) are also loose at the birds-eye.
Please tell more. i.e.: 
“after VS pro-felt, the centers typically measure about X grams of friction, and seem to be stable over X months, etc.”
This is valuable information, and I certainly appreciate you sharing it.
Best regards,

Works great in both directions is my experience.  Also am finding that it works ok on new action part centers that have 0 grams friction - hammer flanges and whippen flanges.
