Last night i soldered some NPT fittings with silver pipe solder and flux from HD. I used teflon tape and then wire brushed off the excess.The tapered end which was threaded I turned down on a belt sander then polished everything with 200 grit then a series of steel wool down to 000 grit. For now i will use the high temp 500F silicone line tied to the handle in place of a valve, ill see how that works during the boil.
Up next a full polish.
Note to self reference the spout to the handles next time!
