How to straighten bike cable?

[Zero Knievel]

I bought this but I don't want to fight the coil.  My thought is to hang it from something, add weight, then use a heat gun to work out the curls.  Will that work?

My best guess is that the steel is the part holding the shape, and that it's done on purpose to keep it on a bike frame and not be a danger.  So we just need the water to get to a couple thousand degrees and keep it from melting the plastic off.

I fear you may be correct.  The heat needed may be nothing short of leaving the thing stretched out on hot pavement during a sunny, summer day.

If I threaten to, how much will you pay me to not?

Heat it 'till the plastic drips off plus another 500F and you'll be in the ballpark of starting to get it.

 

But actually, if you pull it straight it'll relax the coils, the harder you pull the better it works.  Winch, come-a-long, ratchet strap...whatever you got.

Hot glycol - we used that for radiused vinyl widow frames.

Returned what I bought...found this in Lowes.  Does the job with no fuss.

I know what made it coil, the manufacturer, what we won't know is what it takes to un-coil.
