NEVER use air to pressure test a drum/cylinder. Air will cause the drum to explode once the limit is reached. Use water instead. Once the vessel lets go there is no more kinetic energy to cause a dangerous explosion. Fill the drum with water, then pressurise with something like an old mastercylinder from a car. This technique is quite safe, they actually use it to form those odd shape exhausts on some motorcycles. (For those interested this is how it is done: cut the sheet out in 2 pieces, weld around edge, form a circle at one end & fit a plumbers socket in it, then pump it up with water. Some quite complicated shapes can be made using this technique.) regards Doug Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuels list archives: http://archive.nnytech.net/ Please do NOT send Unsubscribe messages to the list address.
