doubt it.
Technique in pinch pull is to have a really good pair of dikes that stay sharp. Not your local Ace Hardware or Craftsman types. Others will stay sharp for a while including the common grade of Klien but the Kilen Journeyman 2000-48 series of or the J248-8 hardened dikes stay sharp longer. Dull dikes are like dull knife blades useless.
So you grab the outer
jacket with the dikes in pulling them away from the inner conductors, pivot on one of the blades to pull the outer
jacket away from inner conductors. Than the outer
jacket once pulled away from the inner conductors and like at a 45 degree angle, than you make your cut. Go around the outer
jacket like this four or five times in new sections. Not cutting while near the inner conductors - more stretching the outer
jacket away from the inner conductors than cutting it. If not all of the outer
jacket was cut away sufficiently, and such areas don't cut themselves away with a quick sharp
bend to the cable, put a sharp angle to the cabe and either touch the blade of the dikes to the remaining rubber or pinch pull those sections remaing and grab the outer
jacket more agressively next time. This until free. How much outer
jacket to grab is dependant upon cable type and experience. With type SJT for instance, one wants to make little nicks to the cable without being able to pull it away completely more than for say SJ and SO type cable that will pull away from the inner conductors completely with stretching.
It's kind of as if you were grabbing this cable with a pair of pliers, pinching them up and rocking that pinched section away from the inner conductors remaining. There is a certain amount of stretch you can get, only in this case you are pulling and stretching with the dikes before making your cut. Takes practice but I don't know of anyone that has mastered this technique that either would go back to another technique or is not just as fast in using it than with other methods including automatic strippers.
No matter what technique you use, as you are removing that outer
jacket - you see a nick in a
conductor's
insulation - even if just small, cut the cable right there and start over no matter the type - that's where the next cut in those conductors is going to be at in time. See hundreds of instances of this per year where bare copper is exposed to someone having nicked the cable and the outer
jacket being pulled so it opens up later.
Most rough of all is Euro cable and Euro heat
wire - even worse than thermoset cable that's constructed in a similar way but out of different materials. Nick those wires, flex and you have a cut. Worst of all is heat
wire cable that is mostly silicone based. At times it will be noted that a just plain light knife nick to the outer
jacket with flexing and time will open up to inner conductors - this without even being deep. Really miss Rockbestos as a brand that was quality.
Most important overall is you don't even nick the inner conductors of the cable. You do so, you start over. I accept the old timers that use a utility kive and won't learn a new better technique as long as the respect this overall rule. It can be done with a utility kife if careful to not hit the inner conductors and as you
bend that outer
jacket in stipping and afterwards - give the inner conductors a good inspection. But it's rough to do so because it's all about the depth of cut. One cannot be lazy in attempting to do better next time or being in a hurry with that method or any method. (Don't strip as much cable these days and infrequently I also nick the inner conductors even with the pinch pull - when I don't pull as much.
Choke it up and cut the cable - don't try to use it.) With automatic
wire strippers it's very much depth of cut and in no way faster than other methods where quality is concerned - this especially where a multitude of different cable types is concerned. My opinion of them in at some
point in my career having had them - don't use them. Not accurate enough, that ripping away of the
jacket over a multitude of
wire types or in reality faster.
Practice and experience is what is accurate and some automatic tool is not going to give it to you just waste your money in making it seem like a pro way of doing it. Experience and technique leads to speed and proper wiring skills. Can easily
beat anyone with automatic strippers. That's experience and technique plus talent that comes from practice and aptitude. I highly don't recommend the use of automatic
wire strippers.
