I Restored this Broken and Cracked Tank for 'Mister Patina'

Mister Patina was recently restoring a german stove from 1920. The tank of it was cracked, the thread for the cap was missing, the cap itself and more. As this job was too much for his current knowledge he asked me if I could help him. I really liked this challenge and I said yes. Soldering is also something I'm not very used to, so it will also be an interesting job for me and it would make a nice little video for the second channel. From the first pictures of the tank I haven't realized that this is made out of three parts. I quickly saw that when it arrived in my shop. That made it a lot easier to repair the cracks. I took all parts apart. Repaired the cracks from the inside, covered all the inside to pervent future cracks and soldered the three parts back together. To stabilize the brittle tank I used aluminium rings. Then I turned a new part with an inside thread for the fuel cap and soldered that in place. After that I made the fuel cap and the bleed screw, to seal them I used one o-ring each
