Making a 1950 David Brown Tractor Fuel Tank From Scratch
Hi folks. I’ve been commissioned to make a David Brown 1950 Tractor fuel tank from scratch. It’s a nice project, with a few quirks, so maybe of interest to others.
I played around with a few techniques - particularly shrinking - as I wanted to see which method would work best/fastest for the given situation. Of particular interest was an old school method of torch shrinking I hadn’t done in a while. Time to fire up the oxy-acetylene 👍 Hope you like the project as it slowly evolves. Here’s the knackered, rusted out tank. DB only made 330 of These, so very scarce! |

First step was to make card templates. I decided to make the top half from three pieces and weld the three together in the center of the double radius. Easy access for smoothing and planishing.

The first side plate came out well. Happy with the fit and finish, although I did employ another shrinking technique just on the edge: my kick shrinker.

Once the two parts were tack welded, some planishing and cleaning ensued to help make the final weld as clean as possible.

I then tig-welded the joint to reduce heat damage. I added additional filler metal to enable enough material for the weld zone to be filed, smoothed and planished. I wanted an invisible joint from the outside. Penetration was super important.
