Blackbriar 8,568 Posted August 27, 2014 Report Share Posted August 27, 2014 You might remember the other day that we agreed my shiny new bearings are 9.5mm and weigh 3.57g each......... Well, today I was in my local recycling project and I found a plastic bag with a dozen or so bb's in it. I paid the chap the 20p (!) he wanted and took them home. There's 3 different sizes, but most of them are 9.5mm...........happy days! Anyway, just out of curiosity, I weighed one. The evidence is below (and I give you my word it's 9.5mm and there's nothing else on the scale, out of shot) Can anyone explain, in terms that a thick twat like me will understand ?

Never thought of tungsten - no real way of knowing as they were just loose in a plastic bag.......... Quote Link to post Share on other sites
