Always a good idea to remember and thank, heartily, those members of the LDS community who indulge (put up with) our little fascination connected to vintage dive equipment...
Photo below is of a burst disk, one of the huge USD 9/16” ones that, well, burst...
Didn’t crack and fail… but friggin’ b.u.r.s.t... notice the substantial amount of missing material from the center... It took out a chunk... well, more accurate to say, put a chunk into, several chunks into really, my friend and good-natured LDS operator... as, if you are not familiar with them, those large 9/16” bolts are equipped with big, too big, vent holes on the flats of the bolt head. FYI - These vent holes are large enough to pass multiple razor-sharp shards flying at 3000psi... probably has something to do with them not being made quite that way anymore...
My friend shook it off as business as usual, as is his nature, but I’m sure it rattled him good when it blew, and I saw the bloody paper towel and the multiple penetrating wounds in his forearms... I just absolutely thank God it didn’t bite him any worse than it did.
Moral of the story... Be extra kind to your LDS man/woman… since they don’t have to put up with our eccentricities, and many of them won’t!
Show the ones who will and do, a little extra love every time you can!!! AND always, ALWAYS, wear a good pair of safety glasses... for pretty much everything that you do short of taking a poop, and maybe even then too... just to be safe...
