The bayonet socket is however safer than the Edison screw as there is no potential to wire it incorrectly. Also as I pointed out else where you could use MK Shockguard bulb holders with bayonet bulbs making them inherently safe, which is simply not possible with Edison screw. No it won't...

Thing is sockets are almost never in a straight line and tend to go around rooms/floors. While we may have more sockets today than 70 years ago I doubt the calculation as to whether it saves copper has changed. However what is certainly utter tosh is the idea that a radial circuit does not...

Edison screw lamp fittings are inherently not as safe as bayonet ones. On an Edison screw it is important that the outside screw bit is connected to neutral for safety purposes. If you have unpolarized plugs like Schuko or the USA ones then you cannot guarantee that. With a bayonet light...

The thing is the reason for the introduction of the ring circuit aka the shortage of copper, is as valid today as it was 70 years ago. Put simply long term there is insufficient copper in the world to go around. Consequently any move to radial circuits in a country that already has ring circuits...

Page here with real statistics http://www.esc.org.uk/industry/policies-and-research/statistics/ Though looking at it, it is for England only. So out of 53 million people there where 28 deaths of which 22 where home or leisure related. This makes the risk about the same as getting...

Most routers come with a parallel fence, which saves the hassle of fixing a batten to run against, which can be difficult on small pieces. It also helps if you have more than one draw front to get slots at a consistent place. I would however recommend practising on some offcuts of melamine faced...

I figured that as well, but surely that applies only till the point you tighten the screw down and the ferrules shape gets distorted anyway.

A follow up. I have been looking for a "cheap" ferrule crimp tool for a bit now. Been just giving the ferrules a light squeeze with pliers and then screwing down till now. Decided to give this a go as £14 is cheap for ratchet ferrule crimpers. Verdict, does take over a week to come but they...

Don't know if this is in common usage, but rather than use a bit of timber as a batten for tiling a better idea is to get a piece of 150x2400 melamine faced chipboard aka Contiboard, cut down the centre length ways. Hey presto two dimensionally stable perfectly straight battens with a nice wipe...

Easy, Googled for a CW1308 data sheet. The idea that more twists of Cat5e would change the impedance is plain silly anyway. What does he think happens when you mix Cat5e, Cat6 and Cat6a when carrying 1Gbps Ethernet, all falls apart or something. He is claiming that in some specific instances...

Which misses the point that an FTTC extension provided by BT will be done in Cat5e. Why would BT use more expensive cable if a length of cheaper CW1308 would give a better result? You friend replaced a length of Cat5e with CW1308 and got an improvement. Did they first check the Cat5e was...

The better solution is to filter the signal at the NTE5 into xDSL and POTS and then run that to the patch panel. There is also no reason not to run them in the same cable, just make sure you use some decent Cat6 or even better Cat6a. Had my broadband done like that for years, and works just...

Then this had nothing to do with the switch from Cat5 to CW1308. For example if you have a FTTC installation and want the modem installed away from the NTE5 the BT engineer will run the filtered xDSL signal to the the modem in Cat5e. The difference your friend noticed was either down to...

I am tiling my kitchen at the moment and after seeing the following post I decided to give it a go on the external corner of some boxing in of pipes in the corner. http://www.diynot.com/forums/tiling/tiling-external-corner.331613/ Although it took a few goes to get the technique right for...

The problem is the cheap detectors are not very good. The good detectors are actually quite expensive, and for finding studs don't appear to offer anything a strong magnet can achieve for a lot less. If you have access to an old hard disks (you can tell I work in IT) then that is a lot extra...

Can also be used for finding wooden studs as well, as you will lock onto the plasterboard screws/nails. Much cheaper than those detector things which don't seem to work very well.

The problem is that all the cheap crap means that even if you want to buy quality stuff, sometimes you simply cannot any more.

A strong magnet is my favourite. The ones you get for child proofing kitchen doors work well. A cheap option if you have access to an old hard disk is to disassemble it. The magnets used for the voice coil on the head actuator will bite your fingers off if you are not careful.

As I outlined a supply coming in in plastic pipe which then turns to copper, then the copper has no direct route to earth, thus could be at anything up to line voltage if it comes into contact with the electricity supply depending on the resistance to earth. There is now a nasty potential...

Other than the resistance to earth of the copper pipe work was rather more than I was happy with. It was in the region of 28-30 Ohms. Either it should be millions of Ohms or close to zero, certainly less than one Ohm. I am not sure I buy that argument either. I would have said from an...
