My dad recently went and purchased a MIG welder, TIG welder, and plasma cutter. It looks like we will be able to weld up all of the keggles ourselves in my dad's shop. I expect we will practice on scrap until we're confident enough to tackle the keggles themselves. My brother is a pretty skilled welder already, but I am definitely not. Very soon I will purchase the last few tri clamp ferrules and other fittings needed to complete the fabrication of the kettles.
There's really no rush to complete this project, as I don't have a place to put the rig yet. The house we moved into last May has a completely unfinished basement. We aren't going to start the basement finishing project until 2015 or 2016. Over the next year or so, I will be working on the design for the basement build. Perhaps I will get the keggles completed sooner than that in order to use them with my existing outdoor propane setup.
