Not quite there yet ...

Antony's Devon 737 project update progress report - you may recall a posting in January this year.

Having take delivery of a sawn off 737-200 cockpit and installed it in a shed, the work began to convert the cockpit into a 737-800.

The pictures below, before and after show how well the work is progressing. The detailed work flow is incredible.

The overhead, MCP and all the instruments, twin yokes and complete pedestal are all installed. 

The motorisation of the throttles is still work in process (requiring a cannabilised cordless drill motor), the J-seat runners are ready to install.

The current picture shows the cut ends of just one of the original Boeing wiring looms, no longer needed. The wiring and connectors to the hundreds of separate cockpit gauges, switches indicator lights etc etc are all ready to connect. Programming them all to interact with flight sim might take just a minute or two after lots of thought.

The current work is focussed on raising the 350kg collimated display to mate up with the cockpit windows after which the displays can be connected to the wiring and the aircraft fired up for the very first time, with everything alive.

Lots on the work list to do, surround sound system and the coffee machine in the galley, for example.

So much easier to build a cockpit from commercially available modules ready to install in a preformed shell or a plywood look-alike.

Anthony wanted the challenge, a discovery path that made him very aware of the detail differences between a 737-200 and 737-800 body shell, most of those challenges now resolved - brilliant.

Sitting in the cockpit makes one realise the level of sophistication involved in designing and building an airframe. This one has found a perfect retirement home in very committed and industrious hands.

Perhaps not so easy to sleep at night as one comes up with solutions to tantalising problems, but the support from internet friends and resources is amazing.

What better hobby?

We will update the Blog to report progress.
