How to shorten a Tach drive cable?

I need to replace the tach cable in a friends plane. The inner part is
what needs replacement. I have access to another cable but the inner
part is too long.
How can I shorten the cable? The end is square and appears to have been
put into a press to form it.

I tried to square up a piece of cable from the old one, with no success.
i attempted to pound it square with a vise and hammer.

I was looking for an old time speedo shop here in dallas to help me with
this, but I can't seem to find them any more. I guess the modern cars
have put them out of business.

Any suggestions?

Auto replacements for spedo cables usually have a fitting that is placed on
one end of the cut to length cable, and crimped in place. The fitting has
the square part on it.

It will be nearly impossible to shape your own end, short of brazing the
end, then grinding down to the desired square shape.

And it will be damn near impossible to get
braze to stick to something so impregnated
with grease.

....and you can get a new tach cable from Chief for about $30.

Thanks for all the info and suggestions.

I had a spare cable and wanted to use it to fix the broken one.
I also just noticed that the one I have has the wrong twist on it.

I'll probably have to order a new one from chief.

Cheers

Just pull out both ends and take them to your local speedometer shop.
They have all the ends and can make up one for you for a few bucks. It
is not rocket science!

Tell me you're kidding! What size city do you live in, that could support
such a narrow specialty? I've never even heard of such a thing!

We used to have three or four of the shops in Tulsa, Ok a few years ago,
and I'm pretty sure as of last weekend that they're all still there.
Tulsa is not that large, and never was; 350,000 or so.

Daytona Beach. Any speedometer shop should be able to make up a new
cable. The fittings are all standard.
