>>920936>own it and control itBy control I mean pic related. With special adapters:
I can refill Lindal valve "Primus" type containers from $2 butane cartridges.
Transfer isobutane from Lindal valve to Lindal valve container. (Mounted)
Adapt Lindal valve appliances to butane cartridges. (Orange)
Adapt Lindal valve appliances to 1# propane bottles. (Silver)
Plus a few other combos that lend to controlling my consumable fuel sources (vs renewable, like wood).
