Build Diary
July 2009  

Having moved the car into the garage ready for work the first thing I noticed was the growing pool of oil under the car. Investigation revealed that the passenger side inner driveshaft boot was split. I strategically positioned a container to catch all the leakage but did no more about it this time. I'll have plenty of time before the end of the build to sort this out.

One of the main jobs I decided to tackle on this trip was to make and install a headlining panel and bracket to hold the panel up at the front, which would also double as a mount for the rear view mirror and interior light. The bracket is simply a piece of aluminium cut to shape and bent slightly at the front to match the rake of the windscreen frame. A hole was cut in the centre of the bracket to accommodate the connectors for the light and two smaller holes either side to take the self-tapping screws that secure the light/mirror assembly.

The headlining panel was constructed from a piece of plywood, cut to fit into the cabs roof space and covered with a thick, light grey material. Spray-on carpet glue was used to fix the material to the plywood. The panel was then offered up and secured at the rear on two small brackets previously fitted for the purpose. The front of the panel is supported by the light/mirror bracket, which is screwed to the top of the windscreen frame. To finish off, two more small holes were drilled at the back of the bracket and self-tapping screws screwed straight into the headlining panel.
Another of the main jobs I tackled was the problem of how to plumb in the Mini heater for water and air. I have previously mentioned that I decided to junk the Panda heater in favour of fitting a Mini item.

In order to get water from the engine to the heater I'd need to go through the bulkhead so I bought some electrical bulkhead connectors that had a large enough internal diameter to fit 15mm copper pipe through. I cut two short lengths of copper pipe and threaded them through the connectors, then tightened them to make a waterproof seal. These will then be mounted in holes cut in the bulkhead. The hoses from the engine will be clamped to the pipe on the outside and two shorter hoses will then be clamped to the inside between the bulkhead and the heater.

I also had the problem then of getting blown air from the Mini heater to the windscreen. I decided that the easiest solution to this would be to adapt the Panda heater box to the task. All I needed was the ducting for the windscreen so I completely stripped it down and removed all of the heater, fan and control mechanisms. This left me with a large, empty plastic box which I then cut down until I had only a small air chamber with the windscreen vents. Of course I was left with some large openings which I blocked with a combination of pieces of plastic cut from the unwanted parts of the heater, plywood and silicone sealant.
A bit more work was also done on the wiring, this time on the handbrake and extra driving lights. I couldn't remember how the handbrake switch was mounted when I stripped the car down originally so I sorted it out as shown in the pictures below. This meant that I had to slightly modify the handbrake lever by drilling a hole in it and fixing a bolt of suitable length in position to act on the switch.

I wired up the driving lights by the simple expedient of fitting a relay designed for the purpose. The relay takes a signal from the headlight cable, internally switching so that current is sent to the driving lights direct from the battery. This puts no extra load on the headlight circuit and so is safer and more reliable.

One of the consequences of not using the Panda heater was that there was a large hole in the bulkhead which was now useless. I cut a piece of aluminium and bent it to shape over a metal pipe before applying some silicone sealant around the edges and rivetting it into place. I doesn't matter that it looks terrible, it will be covered by the dashboard panel.
Having now constructed the heater ducting and the dashboard panel on the last trip I decided to fit it all properly. First I had to cover the dashboard panel to finish it off. For this I used dark grey carpet, glued using spray-on carpet glue. The heater ducting was bolted in and the gaps around the windscreen vents and bulkhead where the floor blower was were sealed with silicone sealant. I fitted a grab handle on the passenger side which also served to fasten the dashboard panel down securely. The panel is secured at the drivers side by the fact that the back of the instrument housing is bolted through it to the structure. I now need to source something to cover the screen vents and direct the air up the screen to finish the top part of the dashboard. I finally fitted the Cinquecento steering wheel to get an idea of the finished look.

And that was it for this trip.
