There was a super ball lodged in a shelf below a machine in the shop one day. It had probably been there for months, casually tossed as a joke after being found in a vehicle fresh from the sale. Just stuck there..... just a little rubber ball.
My eyes tell my brain, and said brain goes FLASH! Ah HA! Chortling like Renfield, I snatched up the ball and scampered.. scampered I say... to my tool box, where I opened a fresh razor blade and sliced that ball clean in two. Why? Because it looks like EXACTLY what I need to create a pressure point against the force sensor I bought. One step closer to a recoil sensing rig for measuring and graphing recoil pulse on rifles!
