Let us know how it works. If it's good, please share your source!

So does it look like you can basically build one of these by having the parts machined and installing a new cable?

Will this work on the window-crank style, or only the lawnmower-pull style gear extension? I have the former, you have the latter.

I was thinking he described his as the circular crank on the side of the cabin next to the pilot’s left knee?

I thought the Js had the lawnmower pull behind the front seats. The vintage birds have the window crank on the sidewall. I'd like a spare sidewall cable myself, there's some wear on the far end of my cable.

The 1977 Js have the old crank style mechanism.

Yeah, I agree with you, maybe I was wishful thinking that he was solving the problem for those of us with the vintage cranks, but you might be right.

I don't have to machine anything. I removed the ends and will re-crimp them on.

I'm just replacing the cable housing which is an exact replacement, and the flex core. The flex core is not an exact replacement, but it is dimensionally and functionally equivalent.

The core in the picture is an exact replacement, but it is wound the wrong way. The manufacturer no longer makes the CW wound cable.

This only works on the window crank version.

Great! That's what I have. I'm watching for your great results!

I was not able to harvest the end ferrules, so I had a machine shop friend make some new ones. The proper cable came in. I’m waiting on new jaws for my crimper, so I can crimp the ferrules on. I didn’t trust re-crimping the ends, so I drilled a little hole in them and soldered them on. I will crimp them too, belt and suspenders. Should be done this weekend.

That is some nice work!

It seems so insignificant when it’s all done…

Until you need it, then it's worth 50AMU!

You should maybe put the suppliers info on that sketch too for saving.  That was a great find!

It's all in the posts above. Besides, I already crumpled them up and put them in the trash.

I’m happy to report that the cable went in beautifully. The bad part was the engagement lever and cable. I’m sure it was the root cause of all these headaches. It hasn’t been right since I’ve owned this plane. The cable was replaced when repairing a gear up before I owned it. I decided to make it right. That only took about 6 hours… It works great now. 
 

Since making a new drive cable, lubing the crank gearbox and the crank. It is so easy to crank down. I can spin it with my index finger.
