Hi,
The boiler built for the paddle engine made for AJG was a little large so it was decided to try making a smaller one to do this job. A centre flue using a gas poker burner was considered but it would have a small water capacity so wouldn't run very long so it was decided to try another pot boiler but with increased heating area. The boiler on AJG was a small water tube which was very low this meant that even an over scale boiler with water tubes fitted would be too high so it was decided to use hedgehog spikes and a long steam heater/super heater instead. The boiler was constructed around a former in the same way as a boiler previously described in another thread. The photgraphs start with the spikes fitted.

The in-line connector serves as a steam dome and a fixing for a removable chimney.

Hello again,
I have been away for a bit.
Some more photographs of the boiler construction. Making the base for the boiler supports and the flame guard.

The boiler would only run the engine for about a minute. So a larger burner tray was made and fitted.

With flame guard and larger burner tray fitted the engine ran for 15minutes until Sterno burnt out. Video.

This is the boiler which will be fitted to a hull of A.J.Goddard which is being made.

Hi,
Having found out that the AJG boiler casing had a round top the two boiler being made have been altered to have a round top.

Hi,
After some delay the round top boilers have been finished.
Some photographs of their construction.
