Gordon,
<font color=blue>I'll go along with the dangerous</font color=blue>
Me too. Thanks for the welding tips./w3tcompact/icons/smile.gif
I first saw the "refilling from another cylinder" procedure in a boating book by Nigel Calder. I dug it out and thought I might add a few lines from that procedure to what you have said.
1. The cylinder to be filled is placed upright, with its valve closed, below the refilling cylinder.
2. The connecting hose is screwed to the refilling cylinder, which is then inverted above the cylinder to be refilled.
3. The connecting hose is attached loosely to the cylinder to be refilled, and the valve on the full cylinder is cracked just enough to blow a little gas at the loose end of the connection, which is then snugged up(this purges the hose of air)
<font color=red> The next step is the primary reason for my post</font color=red>
4. Both cylinder valves are opened wide. Since the fluid in the full cylinder will be at the valve end , this liquid will flow down to the lower cylinder. The rate of flow will be slow(depending on the size of the hose and other things)-it will probably take several hours to get even a moderate full cylinder.
The article continues with ways to speed things up by heating the upper cylinder..hot water and towels.
Propane would have to be a long ways away before I would try this approach. I think I probably would just use the full cylinder./w3tcompact/icons/wink.gif
