The cheapo orange Chinese one works ok for me. Fiddling with the tension nob makes it strip finer wire without ripping off the wire itself. I think it wasn't working in the video because the nut was under the red thing instead of pushing into it. The Knipex looks nice but its $200 compared to $20. The Chinese crimpers seem to suck though, but a lot of that is probably not having the correct size dies for dupont/JST.
Hi, please Could you help me, might be? Then, I am here because I saw the stripper wire pieces alone. I have a tool very similar to the one you disassembled. I dismounted for the same reason as you: it doesn’t strip. When I was taking apart it, that small piece that fell from the tool and you got it at 11:39 and a spring also fell from my stripper. And I discovered the correct place them, yet. Many thanks
I bought #2 (the orange one) when the design appeared in the early 70s - (never had any luck with it, but 40 years later after watching this video I had another go, and after twiddling the chrome (on my version) knob - it works). I got #3 not long after and even then it was a generic item made in China. There are low cost designs similar to the Knipex - Fasen FS-D3.
The greatest thing about using your teeth is that you get notches in them that are just the correct size. You have to keep doing it, though, otherwise the notches eventually get dull.
Very nice to know about different kinds of stripping tols but looks like second part of video was just an afterthought, you should make a photo of the tool before dissassembly or just review the video before making guesses, just an idea, I love your videos. This mystery black part is metal with teeth which is supposed to hold insulation / wire in place, screw is supposed to adjust wire gauge to strip. But, well, in mine tool I think it does nothing because I tried playing with highest / lowest setting and it did nothing except everytime I tried this "black mistery part" has punctured the insulation wchich in case of very short jumpers just defeated the purpose. I think I'll try to find this old tool with fixed gauge if this german tool does the same (pinch on insulation making thin insulation to stretch)
I've got the wire stripper you mentioned second and mine works perfectly, I would never give it away - probably yours is a really cheap one or even a misproduction... The screw at the back is to set how deep the cutting blades go, relatively to the gripping part.
Yeah that piece is supposed to be for adjusting the clamping strength for of the stripping blade to compensate for different size and different types of wires.
I had an even cheaper version of the one you took apart, it broke the first time I tried to use it. Thank you for providing me with another model to buy the chinese copy of...
I have seen the light of thermal strippers. Even a humble little Patco PT-10 will put all of those mechanical strippers instantly to shame. Especially on that PVC insulation.
I am by far below your knowledge and experience level, but I know how to do nicer jumpers and I have no tool for stripping at all, just small cutter pliers lightly closed. What you need to use is long nose pliers. Always bend your wires with the long nose pliers. Now, to make short jumpers, you strip one end, then you bend it already in a nice 90 degree angle with just about 1 mm of insulation bent down with it. Now you turn it around and secure it with the pliers and strip. Securing the wire/insulation with the pliers already prevents the insulation from being pulled off entirely, but the other side already bent will secure it even more.
A flathead screwdriver to remove a Philips screw, using a wire stripper as a pair of pliers... dude, you're just begging for abuse in the comments section lmao .🤣
