the pictures have disappeared from this thread. Any chance there is a copy of them around anywhere? Planning a mod to this collet closer and some pics would sure help.

I wonder what happened to the photos... the edits look strange to me all withing a few minutes and not done by me.

I can't find the photos...

Oh well, it was worth a shot to ask, just in case you had copys of the pics floating around. Thanks for looking into it.

Did you ever get the air leakage rate under control?

On a long shot I looked at my old photobucket account and found the photos.

The collet closer leaks air when open and I just unplug the hose if it will be open long. The CHNC uses a lot of air...

Hi there Big John T, I am having the same issue with my CHNC 1, and am curious if you may have gotten the dash numbers reversed in the first two o-rings you posted. When I search McMaster for 1879T23, I pull it up with a dash of 016 and when I look up the 9452k18, I get a dash of 010.

Do you still have these rings sitting around? I realize I'm responding to an 11 year old thread and am guessing you've tossed them or given them away by now, lol.
