T-Force Air for nailers?

Others posted what happens, a balloon whipping around but on a really destructive scale. I've also seen the hoses attached to these cylinders bust a fitting and tear appart a room as it was whipping around. Of course after this happened the company put in one hell of a safety cage in the test lab! One of our engineers took a big hit on his back as he was diving away...damn lucky it didn't hit him in the head.

Each time a new size cylinder is qualified (for the aircraft industry at least) it has to go through a gun shot test (and fire tests). The cylinder must remain intact (no castastrophic failure of the cylinder other than the bullet hole) but no requirement for where the cylinder ends up after getting shot......in one such case the "marksman" actually hit the valve instead of the tank. Never did find the valve. Most of the cylinders used are a kevlar reinforced aluminum cylinder. Recently they switched to carbon fiber reinforced aluminum cylinders to reduce weight. Only the general aviation rafts still use the old metal cylinders.

It's pretty amazing to see the upper deck slide on a 747 inflate in six seconds......it uses two 1100 cubic inch cylinders using a Nitrogen/CO2 mixture at 3000 psi to run four turbofan aspirators. way cool.

If you ever worked in a shipyard or knew someone who did, here is a story you can appreciate. Beth Steel ran a shipyard in Baltimore that was pretty active up through the 60s or 70s. The phrase "shipyard mechanic", at least in Baltimore, had a particular connotation in the mostly long vanished industrial economy that once supported so many people in this area. Anyway, after completing a ship or boat, and lauching it, shipyard personnel would sometimes take it out in the harbor for a short shakedown. Sometimes there was some horseplay. For instance, a gas cylinder was rolled over to the edge of the ship deck, and the valve knocked off with a sledge. The cylinder would "fly" off the ship or boat, hit the water, and rapidly sail along like a torpedo. With no fins or other controls, the course of the "torpedo" would be unpredictable. On one occasion, it turned full around, came back to the ship, and put a hole in it! The "crew" was able to get back to the shipyard before the brand new ship sank in the Chesapeake Bay.

Well, it is interesting and novel. However, I cannot think of a situation where it would be worthwhile. It shoots 250-300 roofing nails on a single tank. Geepers, that's a lot of bottles to complete a roof. I would guess that number goes down as the nail length goes up.
