Grinding up old sticky rubber
Posted: Tue Aug 27, 2013 9:24 pm
I bought one of those stealth rubber climbing shoe repair kits, which basically have a large supply of finely ground stealth rubber, and far too little barge cement.
Recently I used the sticky rubber powder, and mixed it with urethane glue, to put on top of urethane-glue repairs. It seems really strong, and has shown no signs of breaking on repairs. The urethane-sticky rubber mix is definitely more grippy than pure urethane. I've used this on approach shoes, to replace lugs or repair the instep.
I have lots of marginal shoes with worn-down sticky-rubber soles.
I wonder if I might grind the soles to provide a similar sticky-rubber powder for repairs? Any ideas for the best way to accomplish said grinding?
