my lay shaft lamp

[96terrano]

made this today, originally makeitfit's idea, made it from the 2nd lay-shaft from the Honda Jazz gearbox i recently dismantled :thumb2, will be making more and selling them

Cut a groove in the lamp so the cable fits nicely, and still sits flush to the surface without wobbling

hope it's earthed

just a live & neutral as there's no earth on the plastic fitting

 

[solarman216]

none the less the gear must still be earthed, suppose the cable chaffed through to the live at the base = live gear not good, also looks a bit top heavy, but nice idea though, well done, Rick

Ok, so if I run a earth from The socket plug and atach it to the shaft you won't get a shock? 'i don't know as much about mains'

It's not top heavy luckily, but the others I will be making will have the biggest gear at the bottom, so will by more pyramid shaped

Use 3 core wire, and run the live and neutral to the lamp holder, then crimp a ring terminal onto the Earth, and fix it firmly to the gears like you would an earth wire to the body of the car.

Very important, especially if you are planing on selling them. Really, you should have them "PAT" tested, and marked as well, just to cover yourself.

Not quite, run a three core cable to the light and where it exits the top fix the earth wire to the gear, now that is a more interesting problem, you cannot drill it, you may be lucky and have a oil hole that you can feed the stripped end of wire through and drive in a tapper metal pin to hold the wire, but it must end up tight, once earthed what will happen if the life chafes is it will pop the fuse, Rick

Just stick a candle in it :lol

No cable strain relief going into a metal aperture that isn't earthed...

As the others have said, you must use insulated 3 core cable and earth the metalwork.

What fuse rating are you using in the plug?
The smallest BS fuse is 3 amp, this is more than enough.

Sort out the strain relief at the point of cable entry.
You will then be "geared up" to make some more. :doh

A very enlightening project.

Nice idea but i wouldnt use the chintzy designe shade:nenau

Yeah, you should use remnants of car interior...headlining or seat coverings.
Good idea though and good on you for coming up with the idea :thumb2

Great Idea, if he used the car lights, instead of a Mains bulb, he could have a 12volt double insulated plug transformer, to run it, then would not need to worry about earthing either...

There is cable strain relief where the cable fits underneath

Aye, there's a different shade on is now, a smaller basic one

 

[melissachels]

you'll need to check what the kitemark (safety) standards are & possibly get it tested too. :thumb2

Yes but that doesn't protect the cable from the metal edges that it goes around at the bottom, this is where wear will take place as the lamp is moved.

if you cant fit an earth then the minimum requirment as per BS7671 prt2 is an in line RCD (with test button ):thumbs

That would be a good precaution, BUT it must be permanently wired ie not using an RCD that could be removed.

Adding considerably to the cost though.

Low voltage could be the way to go, BUT the power supply that is CE marked with the appropriate EN reference MUST be suitable for the application in hand, and to what purpose the lamp is being used for.

12volt LED lighting, with a suitable CE marked power supply, might be the way to go.


Using the lamp in a bathroom will be a no no, or near any sinks or water.

When placing an electrical item on the market within Europe for the first time you will probably have to issue a CE Certificate, which means testing and guaranteeing the quality of the item.
I would check what you need to do if selling in a public environment.

I have been involved with the design of large scale sales of industrial electronic equipment, but I am not sure what the status is for just a few items.

I doubt that all items sold on ebay from outside the UK meet the CE regs despite someone sticking a label on them... buyer beware...
