In the end I decided to make the reservoir from 24 gauge copper sheet. The material was on the smaller side, so I could only orient the layout diagonally. The layout lines were very visible on bare copper, so I wasted time covering the copper with layout blue.

After watching a few soldering and sheetmetal videos on YouTube, bending the box into shape and soldering it was pretty straightforward, the box was even oil-tight.

However, it would not fit into the rectangular space in the apron that I had envisioned :-(. Thankfully I got two sheets of copper, so I'm all set for attempt #2. Debating whether to make a rectangular pipe and solder the bottom or to repeat the same layout, just 1/8" narrower.
