26 rpm, thinking too slow? jamesp no, not too slow 1 - the bigger the barrel the higher the fall within(effects impact damage) 2 - and the faster the surface speed at given rpm(also effects impact damage) These 2 factors multiply(not add but multiply) themselves in some way as barrel gets bigger. For a large 9 inch barrel diameter 26 rpm is fast enough Billy. surface speed is 61 feet/min at 26 rpm A 4" barrel only does does 27 feet and a 6" does 41 feet at 26. And there is way more chances for impact damage as the barrel gets bigger. Take it to the extreme - 1 inch rocks in a 4" barrel verses 1" rocks in a 36 inch barrel both at same rpm - bet your life the 36" barrel is a much more violent tumble.
