Ingenious Self Soldering Sleeves! (A Very Old Invention) - ElementalMaker

Thanks for watching! Please help keep the channel sponsor free at www.patreon.com/elementalmaker. Every patron gets a virtual hug and my unending appreciation. I will also build a small shrine to worship you. One of these is a lie. If you interested in these solder connectors, here is the modern day equivalent: amzn.to/2YVNHsT

They trained boy scouts to use these to repair telephone lines before, during & after WW2...

Can't believe you didn't cut it open to see how it flowed, Inquiring minds want to know!

Why does it feel like I'm watching a Harbor Freight version of AvE?

"It smells pretty unique" drops dead

I was shown how to use these during training in the Royal Signals, this would have been in the early 70's. We used D10 cable which is a general purpose telephone type cable have a mixture of copper and steel strands. When the solder melts you have to push the wires in, the problem is this forces some of the solder out and if you're not careful goes all over you hands

That is a really cool trick. Thanks for the demo.

Burns like self vulcanizing bicycle tire patches in the 60's.

You might want to check out the old hot patch system used to patch inner tubes. Worked in much the same way, and could be picked up at any hardware/auto parts store.

A good rule of thumb...when trying something new...read all instructions completely once before trying.

Huh, my grandfather had boxes of these. Was still using them as late as the 1980s to do things on the farm.... mostly repairing this one tractor. It was probably 70% solder by weight. The tractor, that is - not the sleeves.

“They pick great leaders across the world.” Yeah, whether the locals agree or not! 😂

"I can't identify the smell, pretty unique" Drops dead

"For ease of insertion" Demonetized

i think you should make some :D or just one massive one with 15mm tube

Wait a sec, you're not him. Who the hell is this guy?

These connectors used the same composition as Matches Fuzee, which were used to light safety fuze and came in the same boxes. I think they were made in one of the UK Ordnance factories. I was never aware of them being used to connect demolition circuits which were generally not long enough to need joining. They were mainly used to connect telephone circuits which needed to be soldered to stop noise interference and loss of signal from dry joints. In the period just after the War, the Royal Signals were running huge field telephone networks as all the civil systems were trashed. I knew a guy whose job was to run the line from Le Havre to Marseilles. It was strung on trees etc at the side of the road and was kept going by a platoon of guys with jeeps for around eight months until the French telephone authorities got their act together.. I have been looking for the composition of the heating element.. the closest I can get is magnesium, linseed oil, strontium nitrate, rubber and pvc, but this may not be it! I will keep looking!

The last time I saw these was the late 1980s as part of a Damage Control Electricians kit. This is the first time I've seen it used.

This gave me flashbacks to late 1990s history channel. Not the crap they play now. Great job!

Who else heard AvE in your head yelling "Focus you F---!" at the camera whenever it was out of focus?
