Drilling steel.

I had a 350 gallon tank at my Grandmothers place when I bought it from the estate. I hooked up a heat pump, so the propane tank was dragged to the back 40 and opened at the small valve, and then I REMOVED the regulator, leaving a 2.75" hole in the tank. Fast forward 3 years, I needed to clean up some, so I grabbed a hose and filled it up with water and then proceeded to torch it into pieces. It still popped at me like there was gas still in it.
Be carefull!

Casco1: Your story reminds me of a friend's story back in Omaha area. As kids, my friend and his neighbor found out that filling balloons with oxygen and acetylene and shooting them with pop-bottle rockets makes a nice explosion. So, if a little balloon is good, then a 33 gallon trash bag should be really good. They attach the trash bag to the woven wire fence, and stood back and tried to shoot it, but they were too far away. They got closer and proceeded to shoot at the trash bag. Story goes, at 15 feet they had success, and they too couldn't hear for a couple of days AND the neighbor's mother didn't allow her son to play with my friend anymore.

Drop in a pound or two of dry ice. Let it evap for a while then drop in another pound It will displace all the oxygen.

Technically, it will sublimate, going from a solid to a vapor. Evaporate is going from a liquid to a vapor.

Yawn, I must be bored to correct such a penny-enny thing.

Cool idea. Continuous air purge works well too by preventing a buildup to ignitable concentration. Normally, correctly done drilling does not reach ignition temperature tho.

Are you suggesting that I could hook up the dust collector to an outlet while welding? It will move about 1400 cfm through an 8" hole. The 2" outlet would slow that down a bit.

The whole blowing up thing aside, 2 alternate methods to a 1 1/4" drill would be:
1. A cutting torch or plasma cutter followed by a die grinder with a carbide bur.
2. Mark a circle and make a series of progressive small holes, (low speed drill with cutting oil), along the line followed by the die grinder with a carbide bur.
Both methods will be time consuming.

Using the dust collector might be ok, as long as your not talking shop vac.
Make sure the path of dust doesn't go thru the motor to cool it, as that is a point of ignition.
