Ball Charge Specifications
We find that the question of correct ball charge arises often and is still very debatable. Back in 1960, Mr. Bond himself recommended a charge different than that found today.
Mr. Bond himself admitted that it is very difficult to specify a given number of balls of each weight, and in the last correspondence with Mr. Bond, he recommended a charge excluding the 5/8 inch (.61) balls. Because of this, Bico Inc experimentally came up with the following figure for a charge.
25 Balls – 1-1/2" (1.50)
60 Balls – 1" (1.00)
39 Balls – 1-1/4" (1.25)
68 Balls – 7/8" (.875)
93 Balls – 3/4" (.75)
Total Balls – 285
Total Weight – 44.5 lbs
