I picked up some o-rings at Home Depot last night to replace the one in my Touchdown. Now I'm trying to figure out how to get the existing o-ring out of the barrel without messing up the threading for the blind cap.
Ask Luvmysuper Phil about Orings in sheaffers I believe he as well as Doug both have done this
Brian may have as well. There is a section on Binders site on how to restore a touchdown though
I used a very fine crochet hook. The real trick is getting the new one in.
SOme of these comments aren't exactly filling me with hope!
