MIC / Pyro Cable help

[Liamsparks]

Dusted off my pyro tools today - manages to terminate two ends and then the stripping tool started to play up.

It wont successfully strip the MI now and when it starts to it's an extremely close wrap and then breaks off. I've tried multiple times and it wont catch and then when forced it twists the cable and sticks..


Wondering if the blade needs replacing or adjusting?

Hopefully someone can help - thanks

Could be anything from a blunt blade, badly set blade, wrong setting for cable size Imp or Metric. bad method, need to be there to advise properly, in my opinion.

Definitely try a new blade this is often the cause.

Sorry this bloke may give you insomnia, but it is quite a good vid

Thanks for your feedback already - Could anyone advice on the correct "placement" upon installing the blade? How deep should it sit?

Enough to cut sheath shallow enough NOT to damage the conductors, simple really, why do you ask Liam? Contact BICC and ask where you can get hold of a copy of "The Electricians Mate" an excellent guide to everything MICC they used to supply it free. not sure about it now though, I gave my copy away when I packed up working, a mistake on my part.

I always found smearing the copper sheath with a little Vaseline worked wonders with the joystripper, also add a tiny spot on the threads of the pot to help it go on better.
The positioning of the blade on the joystripper is vital, a lot of trial and error, a tiny adjustment can make all the difference.
I remember some gland packs used to come with a little tub of Vaseline, then they seamed to stop it.

Remember using a rod bent @ right angles with a slot in,stripped the pyro that way,or even strip with pliers,ahh the good old days.

That could be a little tricky, BICC disappeared years ago.

Did they even reprint the electricians mate in metric? The copy I've got and all the ones I've seen are all imperial and feature the older style tools, not the modern tools like the one under discussion here.

OK Pyrotenax or one of the other MICC producers then

IMO, I found my side cutters better.

A bit of practice...….with trial and error involved wouldn't go amiss, me thinks...….as long as there's a bit of spare cable available.

Any of the tools with a flat blade like the Joistripper are fiddly to get the blade exactly right, you'll know when it is. It's worth tickling up the blade if it's losing the edge, repays the 5 minutes work needed. I use a regular oilstone.

The only reason I use a Joistripper is for the short throw of the handle. I find the wheel tools ZSU and ZSUS more consistent although again as soon as the wheel starts to get dull, there's no point fiddling about, it has to be changed.

Lucien, when do you reckon it was when the wheel blade tools first came into use? I remember using one in the mid to late seventies and, on one job, a Norweb foreman was amazed, never having seen one before. He got onto his bosses and got a load ordered.
A few years later, I found the Joistripper was what it's name implied, especially making off loads of long tailed pyros into control panels, mostly in industrial boiler houses.
Do you recall problems with pyro and three phase inductive supplies?
I remember supplies to motors where capacitors were fitted to prevent the pyros from blowing. In one instance, all the caps blew up, wrong ones supplied.
