1902 ARROL-JOHNSTON DOGCART

We have an old favourite back in the workshop this week - the 1902 Arrol-Johnston dog car.  Ian has been looking after this old girl for nearly 20 years now and she continues to be used regularly.

You can see that the rear seat base has been removed to allow access to the engine

She is in for a service and for some work on the fuel system before heading up to the Grampian Transport Museum to be part of one of their displays this year.

 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.
