Weights and measures, and plumbing

 I have weighed the car.  Each wheel in turn was lifted just off the ground surface, using a screw jack on some old bathroom scales as a load cell.   It weighed in at about 479kg (including the towbar).   That means it can be towed legally in the UK, by a vehicle which can pull an unbraked load of 750kg.  There is more mass at the rear of the car (280kg on the rear wheels).

Pressure gauge.  I was surprised that the gauge registered 2.2bar when not connected;  This doesn't seem quite right, but STW think that the offset is to ensure that the gauge is correct at around the working pressure.

Plumbing.

I have no experience of making copper pipes fit into a plumbing system. Although I have not kinked the pipes, my efforts to bend them have not been pretty.  Heating up the pipe has effected some annealing, which helped.

Now that the pipes are fixed in place, some pressure testing should be possible:  cold water first, then compressed air.
