How to make your own custom length control cables.

Anyone who has tried to swap out hand controls for a custom applications knows the headaches of finding clutch and throttle cables the are correct lengths (sometimes they don't exist...anywhere!) So I took my new and too long cable to the only guy in town who makes cables, he couldn't do it because the cable was "too large in diameter for what I have". He suggested getting a cable clamp from the hardware store. Yeah, that'll look real professional on my project. NOT

So I had an idea how I could make the cable myself as I sat in the garage contemplating the past week (car blew the motor, communications board went out on my cnc, unemployment runs out.. :D )

First I measured my new cable while it was on the bike (twice) to figure out where it needed to be trimmed. I cut the cable and kept the end I cut off.


Grabbed a small block of 1/2" scrap steel and drilled a 19/64 hole all the way through it. Clamped that on top of another piece of scrap steel

.....and then grabbed my propane torch.

I then took an old junk cable I had lying around and began heating the end of the cable with the 'nub' on it (don't know what the official name is for them) Once it got hot enough I was able to to 'drip/drag' it into the 19/64 dia hole. I did that with a total of 3 cable ends. Then I patiently heated the small block of steel around the hole with the melted solder in it. Once it was sure it was completely melted (I stirred it with a small nail held by pliers) I inserted my trimmed cable into the mix I heated the cable a little before and after inserting it so the solder would get good penetration around the steel strands of the cable.

I held it there for 2-3 minutes while it solidified, then I ran cool water over the whole thing. Then I unclamped the small block and took it to my vise to drive the part out of the block

I ended up using a bolt that was just the right diameter to drive it out.

And here it is...looks as good as the real thing
(except for the blurry pic...sorry)!

Good writeup. Thanks for the info. Has anyone tried this with normal electrical solder? I imagine it would be too soft? What other sources could be used for the alloy to be melted if you didn't have access to old cables?

199 post 1982 pennies, 2 pre-1982 pennies, and 100 g of aluminum makes ZA-27.


The post 1982 pennies are mostly zinc and can be melted on a stove. The two pre-1982 pennies are mostly copper and will melt (dissolve) into the zinc along with the aluminum.


Do not use pennies from 1982. They were made with both compositions that year and are hard to tell apart.
