I have used a 'bladerunner' stripper for the last few years and the first one lasted for about 200 SWA ends (1.5mm2 - 10mm2) until the body cracked.
I would say that you don't over tighten the screw handle and change the blade when it starts to get blunt.

Has anyone ever tried the CK stripper? Are they any good? I'm still a knife and hacksaw person, but it seems amazing that I am still doing it the same way after forty plus years! Most other areas of work have newer method, for example there a cannot be too many sparks still using a rawlplug tool.

Yes, I got one last year.
Brilliant.
It comes with 5 spare blades, which need replacing immediately if you twist it the wrong way.
Other than operator error, I can thoroughly recommend it.

Not the proper one, but I have taken to using an ordinary plumber's tube cutter (looks almost identical) on a few SWAs which seems to work well to notch the strands.

10mm 4 core is baby stuff a decent pair of croppers will slice through swa easy, junior hacksaw and Stanley knife for the rest of cable prep.

BS5308 can be different depending on conductor size, number of pairs and whether individually srceened or just overall, I find once you get up to 20pair croppers struggle to cut the conductors so you waste time getting the side cutters out, better to go straight for the hacksaw

We allow 10mins per gland for cables upto 6mm 4 core to gland off and terminate, can sometimes take longer if the gland plate is miles away from the terminals and you have to strip metres of amour back. We all know you can do the odd gland quicker but not constantly over a 8 hour day, especially if the cables are already clipped to tray and have to have the swa cut to the exact length

10 minutes per gland, that interesting Dave, well it is to me as I have priced based on unit rates for the last forty odd years. That's approx 0.17 of an hour. I would be allowing marginally more. If you have an 8 hour day that's 480 minutes, I think actual output of most employees should be based on 8 hours payy, but only about 6 hours work. The rest is taken up with talking, walking, unpacking tools, packing up tools, and drinking tea. So a unit rate of about .21 of an hour is where I would be. About 36 glands per day. More can be done, but only by the motivated.

But that's based on the knife and hacksaw method. Perhaps with the CK tool, turned in the correct direction, it might increase the output, I'll get one and try.

The CK is excellent, stripping the sheath and armour, then just the sheath is very neat and quick. More reliable than the junior hack saw, particularly on smaller sizes.

Sorry leckie, I should of made that a little clearer, holes will of already been drilled by labourer and the gland bodies c/w with sealing washer and banjo, serrated washer and locknut and 5,2mm hole drilled and tapped out M6. And banjo bolted to gland plate with 6mm bolt etc. The 10 minutes is purely to cut cable to length and gland off and then terminate the cores. We all know boredom will set in and no one would really be expected to be glanding cables all day, but if you cant do at least 18 in three hours as far as im concerned you need to find another job. I am still amazed at how many so called industrial sparks don't even know how to make off a swa gland, the Times you see far too much outer sheath stripped back on both BW glands and even CW glands where the outer sheath isn't even in the final seal, and then you see others who have the outer sheath correctly in the gland and then proceed to tighten up the end nut with all their might wrenching it round and round with a spanner or even worse a pair of grips, they should only be hand tight plus at most one turn with a spanner or half a turn if you're extra tough with your hand tight. Its one of the biggest reasons for moisture ingress

Try this. Set a short hacksaw blade between to strips of hardwood leaving enough of the blade exposed to cut through 75%of the armouring. Strap together with strong tape or bolts. Leave enough wood to use as a handle and hey presto...... saw away to your hearts content without damaging the inner sheath.
Right then back to my Blue Peter DIY Book !!
