John, I think you need to install one nipple in the miiddle of the cable inner before threading the cable through the outers and dealing with the ends – if that makes sense.

You will see that the threaded adjusters for the outers on both parts are slotted, this allows the cable assembly complete with adjuster screws be be prefabricated and easily fitted and replaced.

Interesting, I thought that several complete aircraft had become unsaleable after Westlands declined to continue DA suppport some years ago?

I think they may be MIL-C-22992. They will be very costly, expecially with non-standard keyways which will probably be machined out of solid to order. (There is usually a default keyway for most people but the specials are an even smaller market.) If you are not going to fit it back into the Merlin then I would swallow your pride and hot wire it, or for a high class job, remove them and fit low cost commercial equaivalents in the same holes.

The second one comes off the left hand side of a gyro gunsight

Haha I didn’t spot that – the pilot must have selected Economy Mode.

That sounds like a nice project – mainly familiar instruments arranged in a fun way!

Awesome! and complete with rudder pedals
