What is the shelf life of a tip and how to tell when it is no longer useable?
I came across boxes of the old champion tips with the red fibre base but they
heve to be at least 15 yrs old. Try or trash em?? Must have 500 tips!
Thanks for a reply.
One issue with the old champions is the glue between the red backing and leather may be brittle and allow the tip to pop off. I don't know of a good fix for this.
This thread is a little old, but, to answer the question. The pads on the Champions were installed using contact cement. When the tip is trimmed and burnished the heat often makes this cement soft and squishy. I always put them on a little over size and before trimming I would burnish the sides of the tip a little with a piece of leather or paper towel so as to get the glue soft and then I would just work the tip off of the pad. I then rubbed off the contact cement, sanded the pad which is still glued to the ferrule, then re-glued the tip using my normal glue and then trimmed and continued with my normal installation. In the 60's, 70's and eighties these were the tip that most favored.
