I have two calipers -- one dial caliper and one nice digital one.
I measured a ball bearing the other day on the dial caliper; I couldn't remember where I had hidden my digital one. And, somehow, I read .43125 as .3125. Yeah. I totally dropped the first digit. My brain was probably fried from work, or play, or it being noon, or something.
Sooooooooooo .3125 translates into a tidy 8mm (and 5/16") and .43125 is darned close to 11mm, but not quite 7/16".
It turns out that our Pachinko machine does in fact use the industry standard 11mm ball; I just measured it wrong.
Dang it.
Anybody need any 5/16" ball bearings?
And now I need to go buy some 11mm bearings... eBay has 'em, as do specialty stores. They cost more than 5/16", though.
Dang it.
