winged dome nut (photo) and "master wrench"
Today I saw an interesting dome nut:
http://user.it.uu.se/~embe8573/photos/nut-thin.jpg No sides for a hex spanner to grip! Instead two wings, like a big wing nut only taller and with a hole for the gear chain. It was way too hard to remove by hand power (if that is the thought). So I used the tool on the photo, which I suppose is for bolts and hex nuts, but as it grips like a pipe wrench when you pull, I thought it would eat into the soft metal, which it did. (Yeah, I'm not gonna use the nut again.) I have learned thru the web the tool is called a "master wrench" - I don't know how common that is in your countries, here it is virtually unknown as everyone uses the adjustable wrench. I prefer combination spanners which you don't have to fiddle with. Especially outdoors or in a sub-zero degree workshop, fiddling with tools will kill you hands. Even everywhere else, I don't enjoy it. But in the field if I couldn't bring the entire collection of priceless combination spanners I would prefer the master wrench since it is at least self-adjustable... Yeah, why *are* people so fond of the adjustable wrench? -- underground experts united .... http://user.it.uu.se/~embe8573 Emacs Gnus Blogomatic ......... http://user.it.uu.se/~embe8573/blogomatic - so far: 55 Blogomatic articles - |

As an aside, your photos are almost always too dark and usually with shadows which make it difficult to see details. The so called "master wrench" looks more like something that sounds like a good idea and doesn't work as well as it sounded like it would I prefer combination spanners which you don't have to fiddle with.

Yeah, why *are* people so fond of the adjustable wrench? Basically, I think, because they only occasionally use a wrench and can keep a couple of adjustable wrenches in the drawer which will probably fit everything in the house. Professionals don't use them because they slip and they are larger and heavier than an equal size conventional wrench. And besides, they don't look "professional" so you don't want to put them in the top of your tool box where everyone will see them :-) -- cheers, John B. |

I got a web camera, so I attached it to a pole so it always points to a piece of wood, where I can place things and have it automated in that sense. Problem is it is always too dark even when I (like this time) hold a flashlight directly at the object. It needs more light in general, I suppose. The web cams should come with a flash! Under construction... The so called "master wrench" looks more like something that sounds like a good idea and doesn't work as well as it sounded like it would I like it for field work so I only have to bring 8, 10, 13, 14 and 15 mm combination spanners but still be ready for everything. Professionals don't use them because they slip and they are larger and heavier than an equal size conventional wrench. And slower with less power (yeah, the slip). And besides, they don't look "professional" so you don't want to put them in the top of your tool box where everyone will see them :-) For tool boxes they are OK because you don't get that much stuff into a tool box. But now when I discovered the master wrench the adjustable wrenches will be expelled from there as well. As for hanging them from a nail in the shop, that is OK because people borrow them and never return them (just like the knife and ax) before they make me look bad - the combination spanners tho I get to keep, probably because people aren't used to using them so they don't know they do the same only much better... -- underground experts united .... http://user.it.uu.se/~embe8573 Emacs Gnus Blogomatic ......... http://user.it.uu.se/~embe8573/blogomatic - so far: 55 Blogomatic articles - |

Put some conical reflectors on them and you should get good photos. Light// \\Light object ---------------------------------------- (or at least no shadows :-) -- cheers, John B. |

Depends on what professional you're talking about. Professonal mechanics, working in a shop, don't often use them. Professionals who have to carry their tools around often do. :And slower with less power (yeah, the slip). Knipex Pliers Wrench! -- sig 9 |

Are the positions adapted to nut sizes? In that case perhaps a good thing to have in the box.

Yes. :They look like polygrips but with a flat grip. :Are the positions adapted to nut sizes? They have a fairly large nummber of positions, so they're usually close. The two jaws are always parallel to each other. Usage is to open them up, push the botton that locks the sliding jaw in place, and slide the jaws so they're wider than the thing you're using them on. Put the fixed jaw on one side, push the button and slide the sliding jaw up. then squeze and turn or bend or twist or whatever it is you need. It's easier to do that than ot say it, and with some practice you do it one handed. The movement of the jaws as you close the plier handles is small -- on the 250mm model, it's about 6 or 8 mm, with a handle swing of 125 or 150 mm. so they can grip very tightly if required, or normally tightly with less hand force. I use mine for not only the things I'd use an adjustable for, but also for things like bending sheet metal. -- sig 119 |
