I'm in the eastside of Seattle, WA area and of the few places I have called either send off their decomissioned tanks or they only have Oxy-Fuel ones. Most have been generous in stating they'll hand off a C02 K size when one comes in, but 2 years have passed - and I'm branching out now for suggestions.
K's diameter just feels right - the height won't matter as the cut height I'd expect ~36" tall. An XL (14.5") would be really neat but at the same time huge.
Once I find the tank or tanks if I can find 2. My next question will be who will cut them and what documention will I need to prove they are proper?
