at my school, we have all sorts of equipment, including some welding stuff. this includes a rather large tank. tis probably about 3-4 foot tall. and the dials on the top show that it is at 232bar, or 3000psi. well, i was thinking, what would i need to do to be able to fill my bottle from this? i have read some stuff about all sorts of rigs an stuff. but havent taken much notice as i didnt thinki would be able to fill it myself for a while. well now i have found me a source, i need to know how to do it, and also how to make it as safe as possible, coz i dont wanna get splattered all over the design department, and lose my dad his job. so what can ya tell me. will be very grateful, as it means i will be able to practise alot more often without having to frk out on a dive tank. cheers
