How old a bowling ball would this be? How do you ID one as made of
Ebonite or Vulcanite?
I purchase bowling balls at thrift stores for dirt cheap and pick them
up at the recycling yard fairly regularly (I shoot them from a cannon, and
they tend to be hard to find afterwards). I've also shot *at* several bowling
balls - which is almost as fun since you can put "english" on them by winging
them with a high-power rifle. You can spend all day launching them out in a
field, then make them roll around wherever you want until they get too small
and lumpy..
My point is that I've got some familiarity with the construction of
bowling balls, and the ones I've come across are in two general flavors: solid
all the way through swirled/colored plastic, or cork and rubber core with a
tough outer skin. Is the Ebonite/Vulcanite different, like a solid rubber?
If I know what to look for, I'll keep an eye out and send them to you.
BTW, look at how the pro shops fixture balls to drill finger holes.
Might be useful when it comes time to machine yours down.
