polycord problems

We insert the two ends into a short piece of heatshrink of the same diameter, and then use a plastic welding tool to melt the two ends together inside the heatshrink. The plastic melts before the heatshrink burns.

Besides, using a hot air gun works better. Put the cord behind a hole in a piece of aluminum to shield it so only the ends are exposed. When it gets good and soft push it together making a round ball at the joint. Hold it in the 'L' of a piece of aluminum angle to keep it straight as it cools, then cut and sand the excess off. Never had a failure.

Good luck, and say hi to Joe and Tom for me!

After years of using a soldering iron with a flat tip, last night tried it with a heat gun. Worked great.

1640 uses the magic tool from McMaster. Perfect tool for the job. Makes nice clean joints. Key thing is to read and follow the instructions. Many are loath to do that, but only through the Zen like state of enlightenment from following the directions will you have success.

Use a heat gun, it works much better than a soldering iron. Also try using 1/4", its easier to fuse in my opinion. Be sure to get fully melt the center of the polycord as well. And lastly, be sure not to "over-melt" the ends, if it gets to messy they will not fuse together correctly.

Hope this helps.

we use a sauntering tool and use the edges, melt the ends and then hold them together until the cool down and are tight.
