I had intentions of being more active here, but between the farm, my political position, kids, homeschooling, SWMBO, renovations on the house, a local sort of FB newspaper I run, church, 4H, etc, there just isn't much time.
Quick tip on the propane adapter for filling small torch bottles from the 20lb tank. Set the 20lber outside in the sun on a warm day or inside the house/garage/heated shop till it has warned as much as it will. Put the small bottles to be filled in the deep freezer for 5 minutes. When these two things are done first, the little bottles fill darn near all the way.
Speaking of, what's the trick to gutting a regulator? I spent the better part of an afternoon attempting to use one as an adapter for a weed burner but failed. I did succeed in jamming the spring loaded SS ball so it won't flow anything now.Good tip. Also, vent the air occasionally during filling by blipping the Schrader valve in the small container. When it spews liquid, it's full. (*use gloves, obviously, if you don't want frozen hide). I had to cobble a filler together by hooking a hose to an old torch and splicing to an old grill regulator because our gubbermint doesn't trust us with the ready-made ones any more. (hint, take the guts out of the regulator and turn the 20# bottle upside down so it delivers liquid, and never fill above 80% volume).
