Hey, I cut a nice plug for the top yesterday. I ended up with one inch
of 1"-40 threads on a 1.25" dia plug. I bored a 1/8" hole through the plug, down the centerline. Finally I bored a 7/16" - 1" deep hole and cut threads for 1/4" pipe. I mounted my pressure gauge in the top of the plug. All I can find at the moment is a 0-60bar gauge... 800 something psi I think. It is actually a borrowed gauge, that's why I mounted it in the plug. I figured that's better than trying to fix a big gaping hole in the tank when a new gauge requires an assortment of fittings to thread 1/4" pipe. The fitting on this gauge is brass instead of steel. I don't gat any warm fuzzies from that, but I guess we'll see. After all I am testing Da Bomb outside right? The neighbors have goats..... I wonder how goats respond to 1/4" steel debris traveling at the speed of sound? and a shock wave? "Da Bomb" = "Da Goat Bomb" |

IT WORKS!!! IT WORKS!!! IT WORKS!!!
AHA! o.k....... the news. Things didn't start out well at all. I cross threaded my plug (I have no idea how) and at 40 threads per inch..... they were pretty much immediately wasted, which means the top of the tank was wasted, cause'it's welded in. In an effort to ward off defeat I welded the plug in the top of the tank. Hey, I had to make a new one anyways, right? Next problem was, how the heck am I supposed to get the dry ice in the tank? Anyways to make a long story short.... I put about 1/2 a pound of dry ice and about 1/4 cup of water in a hole for 3/8"pipe and put the regulator back on, closed the bleed valve and closed the regulator. it took about 60 seconds to steadily build 60psi at which point I found a leak. In my hurry I forgot to put teflon tape back on the regulator pipe (where I inserted the ice). CRAP! I had to leave, The previous problems took too long. I was already 10 minutes later for an appointment. I dropped everything and left. Hopefully tomorrow I can start the tank repair. I will note that 1/2 pound of dry ice sublimates into A LOT of volume... I actually bled off all the pressure at one point and closed the valve again. The pressure built back steadily to around 60psi and held. Very cool stuff.... I can't wait to fix my tank. I wish I knew a better way to cap the thing. Any ideas? Remember, it could be about 1200psi we are talking about. |
