--- Quote from: tautech on July 01, 2022, 08:21:53 pm --- --- Quote from: Vince on July 01, 2022, 02:01:39 pm ---Forgive the dumb question, but why not just put that tool in a vice to squeeze it smoothly instead of hammering it ?! :-// The smooth progressive action of the vice would be kind to the lug wouldn't it. I mean a real big/full size garage vice of course, not the tiny vice we use in the lab, that goes without saying ! ;D --- End quote --- With a little care you can indeed make very serviceable crimps in a vise if you know how. Not so much with the smaller cable sizes however in a permanent installation where there will be zero vibration or rarely a need to disconnect it, then bucket type lugs, those without a opening at the bottom of the bucket then soldering on crimps works just fine however a cleaner job is done with a Propane torch rather than Oxy/Acetylene. Crimps in the vice with commercially or homemade lugs really need a reasonably heavy wall lug to withstand the compression as only 2 sides of the crimp are contacted on. First you need a crimp that well matches the cable size and then the Hex head of a bolt or stout nut for just one of the Hex faces to be squeezed into the side of the barrel of the crimp to leave a deep rectangle pressed into the crimp. I've used this method with 100% success over many decades on heavy welder leads and with a couple of layers of shrink sleeve for strain relief it's a quick solution if you don't have some blowtorch handy or your sparky mate with the good crimpers has gone AWOL. --- End quote --- Those are the things that men have done....and should keep mum about. Except in dire emergency, (and this does not include getting standard work done, which is just comfortable to have completed) such as in the field or under the threat of losses of lives or property, they should practice such or make the knowledge available. It is surely nothing that should be written in a forum where some not-so-well informed person might get the idea that it is a technique that can stand in its own right against proper procedures. |

Edit However care must be taken where one might do such non-standard procedures so to properly consider the risk to life, limb or property. --- End quote --- Those are the things that men have done....and should keep mum about.

Woe is me - I feel so strange - since when do I write such comments as above? Is that already a result of spending the better part of the day with that obnoxious Health & Safety guy? Must urgently perform some dangerous acts now! ;) :scared: |
