[ARC5] Spline Adapter

[Mike Everette via ARC5]

I don't have a receiver handy at the moment to check this, but thought the couplings had pins in them to prevent rotation.  Take a careful look at the front side of the receiver panel, at the flange on the coupling.  Should be what looks like two pins.  If so, they would have to be driven out.  Maybe then the coupling could be unscrewed.

As for shafts, in my case, I had several very long tuning shafts (20 feet, give-or-take) with split and unraveling outer jackets. I knew I'd never be able to use anything that long, so cut the ends off, drove out the small pins holding the spline fittings to the cable ends (which are swaged onto the cables, and as far as I know are not re-usable), bored out the cable-end side of the spline to 1/4 inch (it's slightly smaller) and sweat-soldered a length of brass shaft to the spline.  The coupling nut from the cable was slipped back over the spline and a 1-1/4 inch knob attached to the shaft.

Yes, I did try out one of the cables before the surgery.  With a right angle adapter on the receiver, you wouldn't believe how much effort it took to crank the control head.  So much for precision tuning....
