People are always skeptical when they hear how many balls get resurfaced by the same set of abrasive pads at the big manufacturers...
Are they taking into account some differences in how it's done in the factory versus how it's done in a pro shop or even at home on their spinner?
A) The amount of water being used - Those familiar with a Haus Resurfacer know that you can vary the water flow. At the factory the water flow is set to the max and the slurry is filtered and recirculated through the system.
B) They are working with undrilled and possibly unlabeled balls - Inserts that stick out above the surface of a bowling ball will cause premature wear on a abrasive pad. Sharp edged holes, engraving and even beveled holes create areas of higher PSI against the pads. Again, this can cause premature wear.
C) I believe most companies are using 3 abrasive pads - Most people that do their own resurfacing are doing so by hand and using 1 pad for roughly 232 square inches of bowling ball surface. At the factory they are using 3 times the pads on a machine that uniformly resurfaces a ball with less "overlap" than using a spinner at home doing 4 sides of a bowling ball per grit.
Just something to consider...
This also may not apply to companies outside of Ebonite, Columbia, Hammer, Track, and Brunswick.
