I have a steel Stewart speedometer cable that is 67" long. According to Russ it is typically 63" long. Has anyone out there ever cut through the wound steel cable and reinstalled the crimped end. How does one do that?

Yes, I have. I cut a bit above the end so that I have something to grab to peel the cable out of the inside of the end piece. Sometimes it is soldered on too, in which case you have to pull with vise grips while heating with a MAP gas torch.

When you get the end off then you need to clean out any solder, and also pass a mandrel through to straighten out crimps. You can make a bullet size mandrel from a bolt by rounding off the end.

I solder them back on because that way grease can't leak out.

I haven't tried this on a speedometer cable, but when I need to cut a brake cable for one of my bicycles, I first cut a short piece of heat shrink tubing and slip it over the cable area I want to cut, then heat shrink it in place. The tubing holds the strands together so that they don't unwind at the fresh cut. :-)

Ok I'll cut the steel case first ... secure the end piece ... and pull out the remainder with vise grips and possibly a torch. Then reform the end and tin it ... then assemble crimp and solder. Got it.

Thanks

Are you talking about the inner drive cable or the outer housing? I would cut the inner drive cable if needed, but I would not cut the outer housing for 4 inches.
