yes.

i've used a strand of the brake cable itself. it's a little harder to get the solder to stick, but it works.

one major thing about doing this, though.

when you're done, yank on that little sucker as hard as you can and make sure it's on there. if it falls off and gets sucked into your engine, throttle cable length will be the least of your worries.

some where in the video I'm measuring the dia of the cable end ferrule I say its 0.016 should be 0.116 my uncle caught that.
Bob and I did a cable end by pouring it, his camera acted up I think he didn't get it on video so he's never posted it or else I was cussing too much???... I just don't know.
Today I was working on my never ending first build. I finally got up to installing the throttle. Of course like everyone else, mines too long. I did a search to see if anyone had any suggestions and came across this thread.

Many thanks to Norm. I followed his directions in his very good video and it worked like a champ and really was easy as pie. I'll never be intimidated by that again.

I want to praise this video as well. i cant wait to chop down my throttle cable. i have a huge loop circling my other cables.

Question about the silver solder though. Does it have a much higher melting temp? so it wont heat up and come off in the carb?
also in heating the cable-
i dont know if my cheap soldering iron can do the job, short of making a dry joint, and i wouldnt trust that.
i guess im wondering if im going to need to buy a torch?

You will need a propane torch if you use real silver solder it melts at very high temperature the cable and copper will be glowing hot.
A soldering iron will not work.
keep the heat right on the wrapped copper don't try to get too much heat on the cable except where the copper is. You will also need a flux. Borax is what I use for flux. When you hit the proper temp the solder will flow into the copper and cable like water the flux will turn to a sort of glass like looking poo. You can clean the glass looking flux off with a wire wheel. It takes only a match head size or less of solder,you should be able to still see the wraps of copper wire. Done properly the end will never come off.
Too bad the video of me pouring an end on a cable using a home made mold using wheel weight lead had turned out, I remember Bob had problems with the camera's battery.

Hey you guys are welcome! I have molds I made to cast the bigger ends on cables. Bob and I did a video of it but it never turned out, problems with the camera batterys. some day I'll give it another try.
I've made cables for big bikes, real airplanes,motorized bikes, I don't need to buy cables or wait for a cable to be shipped, you guys can do it too, err not wait on some place to ship you a cable if you roll your own.

I just wanna add That those throttle cable ends are very important also ....and that I came up with another way that also works...

I take one of those butane micro torches and I heAt the end red hot by legnth of how long nob i wqnnaq make. Then I fold it over wile its red hot real fast and then sape it into a nob

But used two sets of needle nose VISE GRIPS aaaand a pair of needle nose pliers
