Throttle enable cable fable...

My throttle cable assembly is one part of the car that has been in the design phase for literally years. At last I've been able to piece together the critical parts.

The generic cable from Venhill uses the welded-on nipple fitting in the standard throttle roller fitting. The cable then travels through the recycled Yamaha bolt-in ferule before travelling through the Venhill outer until it reaches the threaded cable adjuster which is mounted in a fabricated stand-off tower using a nice grommet from CBS to seal it off while allowing the thick-end of the adjuster to travel into the tower.  The cable exits the adjuster then travels 90 degrees around a special machined acrylic rolling-shaft before joining to the pedal by means of a Venhill U-shaped fitting, bolt-on nipple-end and a rose-joint.
It needs some fine-adjustment and a brace for the tower but works a treat.  It will sound silly but as this is all of my own design (with the goal always being a smooth, long-travel pedal) I am rather pleased.
Now to try to find a very short turn-buckle or similar to act as the brace for the tower...
