| 1902 Arrol-Johnston Dogcart |
The Arrol-Johnston has come in for a visit prior to an event in a few weeks' time. Ian went up to service her and discovered that the top water jacket plate had developed a number of cracks and was no longer serviceable.

This is a cast aluminium plate and, unfortunately, would not weld. Due to the time constraints on us, Ian has fabricated a replacement from sheet aluminium by cutting and milling the individual parts prior to welding them together and final machining.
