Yo Bad Dudes (and Bad Dudettes) . . .
My good friend 'Bad Cowboy' passed me a STUN Runner yoke for a repair and restoration.
This wasn't to be a 'pristine showroom quality' job but good enough to be clean and fully working.
Initial thoughts and reports were that both trigger fire buttons were not functioning, and the entire thing was rather dirty and rusty.
I'll mention at this point that this repair was a 'bloody pig' . . . one of those jobs where you open it up and five pieces of random gubbins falls onto the floor . . . and to assemble it all back together again requires four hands.
Ok, we open her up and see what we can find.
The control yoke had left and right control and also forward and backwards which was accomplished by the two potentiometers which I ringed in red. Both checked out to be operating fine. I applied a little switch cleaner in there just to make sure. The forward/backward potentiometer didn't pass through it's full range of motion (which I made a mental note of). It looks like this is correct from what I see.
We open the left gun handle.
A finger trigger operating a leaf switch as can be seen. There is some poor wire repair work here (black electrical tape) and the wires are badly frayed. I replaced both the wires and repaired using heatshrink tubing.
(Later I found that the leaf switch contacts were either dirty or rusty and needed a application of fine wet and dry paper with some WD40 to clean them back up into full working order).
Then we move to the right control handle.
The wiring here wasn't as badly frayed as the previous side but once again I repaired it in a similar way with two new wires and heatshrink.
Worse . . . the sprung metal tab that held the trigger forward had snapped off causing the red trigger button to fall inside the handle.
Some careful metalwork was needed here (basically I wedged the sprung metal between two other thin metal tabs I fabricated and put it back in place within the leaf switch mechanism).
Back to working again!
Finally, a careful application of black hammerite paint (which took a god-awful time to dry) and we have a winner!
