I have seen inside Air cylinders that have been refilled by scuba and pumps. Almost without exception the Air cylinders filled by scuba showed very little to no corrosion whereas the ones filled by hand pump developed corrosion more quickly and progressed rapidly.

I remember Ulrich Eichstadt ( Walther ) describing some of the cylinder interiors he has seen as resembling minefields the corrosion was so bad.

The interesting point to me was the increased rate of corrosion in cylinders hand pumped versus scuba filled.


Scuba pumps have pretty extensive moisture traps on them. Compressing air is condense a lot of moisture and the last thing you want while diving is water fouling your air supply somehow.

I just calculated that the energy of the gas inside a fully filled cylinder at 200bar is 0.00359kg TNT equiv. A typical hand grenade has 0.0150kg TNT.

So, 3.59g vs 150g TNT

the blast wave of a typical hand grenade is very weak, it needs to be within a few inches from you to kill you, from one meter it's harmless (we're talking the blast wave, not the shrapnel). It will take your hands off if your're holding it.

if you don't have your hand wrapped around the cylinder, nothing will happen, with your hand something like 10 inches away from a cylinder which explodes nothing will happen.

Now, what will happen when it bursts while you're holding it, I don't know. I have an old cylinder which I could wrap with chicken wings and throw into fire :D I'd say some of the fingers will come off, will tear skin and tissue of your palm.


There are various outcomes you forgot to mention:

1. Mr. “Smarty Pants” comes out unscathed, but later on has some degree of permanent hearing loss. Lesson learned.

2. You get some shrapnel, become maimed/handicapped or a vegetable for life.

3. The Grim Reaper gives you no mercy, you’re six feet under, R.I.P...

Dude, don't tell me you got one in the first place because you're a James Bond fan?

Well, I am both a former (NRA) Master Classification 10m AP shooter... and a James Bond fan.

Though chronologically, I became a James Bond fan in 1962, some twenty years before I bought my first airgun (1982).

Didn't buy the LP53 until last year. Complete with original box, and ALL accessories (extra sights, cocking ball, cleaning rod, instruction book, factory proof target, and rare barrel weight, etc). A collector's item, you know.

Be nice, now...

Don’t worry, I was just joking around with you. Whoever gets or owns a LP53 is most likely a Bond fan.

I also like James Bond, that is the reason why I own a Walther PPK, but I don’t have it as my primary CCW.

You’re smart in snagging the LP53 with all the goodies. I bet it’s a safe queen, and will continue to appreciate in value over the years.
