Newb to tig welding, and havent touched a lathe in a few years, but had some time today and made up a fitting to route my steam line to the upper rad hose.
I made a "temporary" fitting well over 5 years ago and it never gave me any issues but it wasn't meant to be permanent and it started to corrode being in contact with 2 dissimilar metals (brass and the galvanized steel).

Not really a big fab job, but it counts!

 

It's nice when you have tooling to fabricate what you need.
