Lobo,
Actually I have two different sizes:
Diameter (inch) | Weight (ounce) |
7/8 | 1.2 |
1 | 1.8 |
The 1-inch ball consists of a
7/
8 inch steel ball bearing with a
1/
16 inch soft rubber coating (I slit the cover on one and measured it). The smaller ball has about the same resiliency to pressure, so I suspect the coating is also about a sixteenth of an inch which makes the bearing
3/
4 inch in diameter.
The rubber coating does not stand up to a lot of abuse, but it's OK as long as you are slinging at soft targets. I haven't actually used them much, because it is hard to find them again. They are grey to start with, and the soft rubber coating picks up dirt like a magnet...
