gday all
well the next step has happen I picked up a mapgas today so very happy for that only paid $60 for bottle and torch. Now only need to pickup some flux and solder, so that gives me 2 kegs some copper and stainless pipe some 4" and 3" tri-clovers all to play with again. Fun building a new still from the ground up, just wish I had of brought more of my old one with from Oz. Oh in NZ now. But in saying that its a hobby and hobbies are about having fun hey.
So question I have today is well maybe not question as such but some ideas I'd like to come off my 50lt keg in 4" copper so i'm think 4" tri-clover on top of the keg? So I don't have any argon and don't really want to have a bottle sitting around anymore and seeing I'm new to the world of mapgas and such whats everybody's ideas.
Looking forward to peoples Ideas.

hope Ive put this in the right spot

Spend some time working out how to soft solder stainless and then solder the 4in ferrule on its more than adequate for the job.

Thz coffee addict. As a retired boilermaker soldering is a hole new world to me. But spend much of yesterday reading and watching youtube videos and believe I have a hole outlook on soldering. Still have not made my mind up on which way to go. So how the old tig sound hard lol. But we'll see I guess
