I have been working on repairing and restoring this Burrell Showmans Engine at our works. It was originally just a working engine, and was converted to a Showmans many years ago.
.
……One job was to make a new steering drum, with a spiral design to locate the steering chains as they wrapped around it. The one on the engine was just a plain fabricated tube with flanges at each end. I wanted to try and produce one similar to the genuine original cast iron spiral design found on some of these engines.
.
……So in two stages a total of almost 4 metres of 30mm diameter solid black bar was heated up with the Oxy/Acetylene torch, and steadily wound around a 125mm diameter thick walled steel tube.
…….The 30mm bar has a pitch of 31/4 inches, about the same as the genuine item.
…….The bar ends have been trimmed and blended in flat, it is quite a weight already, and there is still plenty more to do to it. The spiral bar will be fully welded all the way round.
