Extension cable loosing flexibility
"john reeves" wrote in message ... This is about those extension power leads ( usually orange coloured from B & Q etc). Quite often sold for use with electric lawn mowers. These cables seem to have 'a mind of their own' every time you reel them up and unreel them. It's like a 'memory effect' they have, ( as if they are not flexible enough ) and want to keep moving in a direction that they must have been stored in previously. This probably sounds like a minor thing. But the total time wasted and frustration trying to unravel the thing mounts up time after time. I've tried that trick sailors use in giving it a small twist every time you reel it around your arm, but its just a bit too stiff to do that successfully. Has anyone else found a good way to deal with this? It has crossed my mind that this cable is just too old and has lost what flexibility it did have once. We use a device similar to this: http://www.metals4u.co.uk/detail.asp...36&prd_id=4342 although ours has two swivel handles, one that is in the centre of one side and the other at the end of the other side. You simply push the plug into three holes on the flat section, hold the centre handle and start winding with the other. No twists, no tangles and the cable has lasted for years. -- Tinkerer |

What does that BS number mean? http://www.bs6500.co.uk/ No involved with Eland cables are we? B-) Doesn't say a lot in terms that can be reall pinned down. Anyway my B&Q "Masterplug" extension cable, after being out in the porch over night at 0C, is stiff but still coilable without it fighting back a great deal. -- Cheers Dave. |

Even the most expensive and flexible of cables take a 'set' - due to being supplied on a drum of some sort or the other. So you still need to develop a technique for tidy wrapping up. The trick is to coil it in the direction it wants to go. And in a coil size it's happy with. -- *Sleep with a photographer and watch things develop Dave Plowman London SW To e-mail, change noise into sound. |

This is how the noise boys do it. They wrap a lot of cables, some of them 100's of metres of multicore which is a damn sight stiffer than B&W mains cable. I doubt that you mean that literally for hand coiling, it would be too damn heavy! 50m of heavy star quad is too much and my hand isn't big enough even with each loop taking 5' of cable... Multicore over about 20m is figure of eighted on the ground or more likely wound onto a drum. Not coiling the multi by hand, but doing the same over/under twisty thing whilst coiling it into its flightcase. Once this is done you can grab the end and just run off with it down to FOH and the cable comes out perfectly straight with not a twist or snag in sight. Gareth. |

No. Do not twist. Twisting is what leads to kinking and tangling. The correct way to coil a cable, rope, or hose, is to imagine that it were a flat ribbon with the two sides a different colour. Suppose the ribbon is lying flat on the ground with no twists in it so that the blue side is on top and the red side underneath. (For a right handed person hold the end of the cable in your left hand blue side up. Grasp the cable with your right hand, holding it blue side up, then bring your right hand towards your left hand and just place the cable onto what is already there, so that it stays blue side up during the whole move. The action of your right hand does not involve any twisting. You just lift a bit of cable straight up and plonk it down again, as if you were lifting a chess piece from one square and putting it down on another. If the cable is stiff, a side effect of this will be that each coil will end up with a self-cancelling double twist in it, and will most likely hang in a figure of eight pattern. But that's the idea. Ronald, as a sailor you should know the difference between a cable and a hawser. And of course the hand you use should be the opposite one depending which way the rope is laid. When you are coiling twisted rope it's imperative to coil it in such a way that the twist is not destroyed. This is of course not an issue with plaited ropes, mains leads or garden hoses. Andy |

Ronald, as a sailor you should know the difference between a cable and a hawser. Naturally. And of course the hand you use should be the opposite one depending which way the rope is laid. Not necessarily. If the method does not add or remove twist (and the one I described doesn't) then it doesn't matter which hand you use. When you are coiling twisted rope it's imperative to coil it in such a way that the twist is not destroyed. Fair enough, but the other important consideration is that you want the coiled rope to uncoil freely without snagging. For that, it's important that the coiling and uncoiling procedures should be mirror images of each other, in terms of any twists added or subtracted cancelling out. Imagine trying to coil a rope the other end of which is tied on to a fixed object (not that you'd normally do this - you'd start at the fixed end pulling the loose end towards you). If you added a twist with each loop, then by the time you got near the fixed end, it would all be a twisted mess, having suffered an accumulation of anti-twists (you can easily convince yourself of this by imagining a rope tied between two fixed points, then grabbing it in the middle to apply a twist - then on one half of the rope the lay will get tighter, on the other it will get looser). What would be OK, though, and is the recommended method for coiling stiff stuff like electric cable or water hose, is to give a positive twist to the first coil, then a negative twist to the second, and so on, alternating positive with negative so that the overall effect along the whole length of rope is neutral. One of the methods of tidying a rope is to roll it up on a drum (this is the preferred method for garden hose). Having done this, it is imperative that the rope, when next needed, should be taken off the drum the same way, i.e. tangentially, so the drum revolves in the opposite direction. What you should not do is remove the rope axially, such as by laying the drum flat on the ground (axis vertical) and unwrapping the loops up off it. Depending on which side of the drum is uppermost, the uncoiled rope will have its lay tightened or loosened. Likewise if you were to wrap rope onto a drum axially, you should not then unwind it tangentially. One traditional method of coiling rope is not into the hand but flat onto the deck (or ground). This is equivalent to wrapping it axially onto a drum, and leaves each loop neutral while adding and subtracting a half twist to alternate half-loops. Laid rope is usually flexible enough to absorb these half-twists without trying to lie in figures of eight as a stiff cable or hose would want to do. |

Unless said hook is fairly broard, couple of inches wide and curved. A velcro based wrap is useful to keep the bundle tidy. *Do not* tie an end around the bundle it will damage the cable over repeated ties and time besides which a knot works loose. -- Cheers Dave. |

Ah right the multies I use are kept on drums not in flightcases. Flightcases would take up more space in the cable tender. Even a small outside broadcast will have half a dozen or more 8 pair multies up to a few hundred metres long depending on the venue. -- Cheers Dave. |

I "installed" the cords as follows: I put the plug end through one of the holes in the side of the reel, and left about 6 feet hanging out.

The reason for the 6 feet is that all of my garage receptacles and and the receptacle under my raised deck are 4 - 5 feet off of the ground. If I started wrapping the plug end tight against the reel, I'd have to unwrap the full cord in order to plug it in. |

If you are only using your lead for a short period over a short distance and with a small load and you leave it coiled, 'sort of OK' However, if you are running a large load, Electric Fires etc, uncoil THE LOT and snake it out. I had an 100 Metre extension lead made just as you described. Some boatbuilders borrowed it to run an Electric Fire in their 'tea room'. Overheated and buggarred up the complete reel.
