I use a propane/oxygen Smith Little Torch for soldering and have it hooked up to my house natural gas line via a G-Tec gas booster (much safer than having propane in the house). I also use this torch for quick enameling, as well as a small old kiln I got from Metalwerx. I have a home made ventilation setup to vent out any soldering/enameling fumes. My favorite equipment is my car battery charger based electrolytic etching setup. A few things I’m missing are a good rolling mill and some lapidary equipment.
