oh I see... I wouldn't be the 1 doing it for certain.. I would have taken it to a welding supply to have it done, but I forgot that the little bottles were illegal to refill, and certinly a company is not going to do something illegal like that, not when there liscenses involved to deal with the stuff...
I have the fitting that fits the small propane tanks to fill them, but I know that is a much safer deal.
now comes the question, how do I get rid of the empty bottles?
