--- Quote from: tautech on July 01, 2022, 10:57:59 pm --- --- 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. 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 --- Hey Vince, about the vise crimp we're trying to achieve with a Hex nut or bolt head, similar to this done with a commercial tool with a plunger pressing into a Vee .... this one a double - crimp some are + plungers. Anyways, just the flat of a Hex done longways or across the lug depending on the size of the lug and the bolt/nut hex used to squeeeeze it together. This is for a pis ant old and little 140A caddy welder lead, didn't check but probably 25mm2 cable and 13mm hole in the lug. Muppets that made it couldn't even be bothered to sleeve it for bending strain relief so it's starting to show signs of early failure. :horse: Final word: Any lug crimp for mains must be done with approved tools to meet compliance.......trying to get my sparky mate's old crimpers that he can no longer use for NZ mains work and comply with a COC. (cert of compliance) --- End quote --- OH it looks like this lug is soon to part with that wire ! :-DD Time to get that Hex bolt and vice in action, replace that crimp and show us nice pictures ! I am waiting ! >:D Going to bed, good night.... :=\ |

The say that they are marketing and sellers of medical equipment, not makers or engineers, so the person may honestly be unaware that something vital is missing. I hope that the seller accepts the complaint and refunds you in full, and you get to keep what you have. But based on recent experience with eBay and their customer support with my recent problem, I wouldn't be surprised if they have to step in and decide who is at fault that they side with the seller. You will remember that I recently sold some speaker stands via their GSP program, and despite the fact that I spoke to a customer support team member in Utah, who told me that they would find in my favour, they ultimately did the complete opposite. It was a fecking good job that had the foresight to actually pay more on the carriage to provide insurance on the item, otherwise I'd have been £50 out of pocket, as it was I'm about £3 out of pocket, the cost of the insurance because after a few weeks I did the insured value back. Ebay is not the place it once was, it seems that they are like most other corporations today, obsessed with money and fair play seems to have flown out the door. --- End quote --- There's no way the seller didn't know about this condition; you literally cannot handle it without the back falling off. The only thing holding it together was the bubble-wrap. LOL... You'd think 100% feedback means that wouldn't you...? But no... eBay has a system, and sellers game it constantly to keep a high feedback rating. High volume sellers can get 5 bad feedback removed from every 1,000; and there are numerous other tricks a seller can use as well. eBay is much more about damage control to the eBay brand than they are about actually providing a safe place to buy or sell, and they have been for a long, long time. I recently posted neutral feedback on a purchase where this happened: The seller sold a foam surround kit that was supposedly "for my RS-3000 speakers", but when it arrived, the "cement" in the kit was common carpenter's wood glue. Now this is not the best choice even for paper cones; it soaks into the cone and if you have to remove it, it destroys the paper... like say, if you need to replace the foam again in another 15-20 years. ;) But it is absolutely the wrong stuff for a poly cone speaker. Will not stick to it at all. :palm: My feedback was neutral, and I gave 5 stars on all other aspects as shipping was reasonable and prompt, and my comment was absolutely factual - that they'd sent carpenter's wood glue instead of the cement needed for my poly cone speakers, and that even tho they'd refunded purchase price, the return process made me eat the outbound shipping. Gone the next day. Cheers, mnem eBay is a cesspool. never spend more there than you are willing to write off as a bad day. --- End quote --- gotta' agree with the dragon on this one. with those two T-15 screws missing from the back the cabinet will almost fall off on its own. (don't ask how i know) even if you did not know there was supposed to be a display board inside, how could you not notice the ribbon cables hanging loose inside? will be interesting to see how it all plays out. edit just looked and there are supposed to be 3 screws back there. mine is missing one. |

If so, sorry, but I think they have fulfilled their brief. Ok, it is clear that at least 1 PCB is missing, are they supposed to be aware of that? It sucks, I know, but the Dwagon is normally more astute than this, did you not ask any questions about this? --- End quote --- Short version: It was sold as an oscilloscope for parts, not sold as 75% of an oscilloscope with crucial parts missing. That is "significantly not as described". As I explained to Vince; had it been a non-critical external part obviously missing from photos, or an accessory, that would have been different. There's fair reason to believe the seller knew they were doing something dishonest, or they'd have taken the whole monitor. It is much easier to remove than that PCB and doesn't risk causing a CRT implosion. Of course, taking the whole monitor would've left a very obvious hole in the face of the unit. SELLER HOMEPAGE: https://www.ebay.com/usr/tekyard_medical mnem Those bent pins on the CRT totes made me go tho... --- End quote --- After some 10 years of spending rather too much of my working life on Picture monitors (I'm an RF Tech for Pete's sake!), I found that CRT implosions are rare to the point of invisibility. Even when we wanted to dispose of CRTs & needed to "de-vacuum" them, for anything other than very early, (think 1950s style) tubes, chucking them into a large empty dumpster would not cause this to happen. We had to resort to a long length of "star picketing" metal to break the necks of the tubes in the dumpster. The result of a successful use of this device was a gentle "sigh" from the tube as the air rushed in. I think a lot of the :scared: :scared: :scared: :scared: about tubes comes from the quite large PPI Radar tubes that were widely available surplus post-WW2. They were definitely scary! The 1950s style TV tubes still had problems, hence the safety glass protection common on TVs of the era. From the very late part of that decade, tubes with bonded safety glass virtually eliminated the danger. Later, more "high tech" designs used a much less bulky bonded safety shield, combined with steel strapping which directed the force away from the front of the tube. The main "danger" of "gorilla like" handling of modern CRTs is breaking the neck, & turning a useful device into a paperweight! |

All what I need is to stay passive as I am now....no change in my current contract. I sent already an email... I am scared to read their response. --- End quote --- Most of the horror stories I read about are exactly the opposite: some monkey-butt thinking they're going to "stick it to da man" because they read somewhere that the electric company has to allow you to backfeed and that they have to pay you for the electricity you generate. In those cases, you as a "power plant" have to ensure QOS and they will have very specific demands as to the hardware they allow you to connect to their grid. In a "consumer-only" scenario, I believe there is going to have be some form of power conditioning or isolation that has to be installed between "your grid" and "their grid"; even if it is as simple as you using a big-arse transformer to charge your battery bank when needed. I do not believe they will allow you to connect their grid directly to the solar-powered/generated AC you use for your own household AC power under any circumstances. mnem :bullshit: --- End quote --- --- Quote ---Unfortunately you can’t keep the same meter as that meter is not equipped to read the solar panels. The new mater works in conjunction with the panels and that way we receive the correct information from the panels as well as the usage. --- End quote --- I knew it :palm: I will try one more time, but they are forcing me to go off grid... 1) I do not want to buy at the double price I am selling back to them 2) I want to put how much panels I want on my roof in my property 3) Yes the base price for a bidirectional meter is 16$ instead or the regular 12$ each month, and recently a power company in the area bumped it up to 30$/month just because. It not about the business case, it's the principle. 4th July is coming..... I N D E P E N D E N C E |

That's more generous than most stories I've heard. 2) I don't know if that's "I want to overbuild" (tho I suspect so with you ;)) or you mean you want to build to a spec. 3) If you just want them available as backup, seems to me that a huge-arse transformer to charge your battery banks... and a failover switch just in case... and they can keep their pervy bidirectional meter. :-// As for them expecting to collect data from your solar panels... that's a nunya. As in "NUNYA FUKKIN' BIDNESS!!!" :-DD mnem also nunna my fekkin' bidness. ;) |
