Antique lamp needs earthing

[yellowvanman]

Customer wants me to fit a new antique centre light.

Body is brass but the lampholder doesn't have an earth terminal.

Been looking for a new lampholder with an earth terminal. There is some thread sticking out of the bottom of the existing lampholder, enough to screw another lampholder into, but the thread is 3/8. Can't seem to find a suitable adaptor/lampholder.

Anyone know where to look?

Can't secure an earth to anywhere on the existing body.

Either that or no lamp, just make it look neat and tidy

Just need to get some small self tappers!

You can defo get adapters try a lighting shop, hardware shop or a small independent wholesalers

Try collingwood or stearn I think they do adapters from 3/8 to 1/2
i sometimes used to solder an earth onto the lampholder base if it was an oddball size

Have a look down this page there are 3/8 lamp holders. A99 is the product code

Sorry the thread is 5/8 not 3/8

 

[GLENNSPARK]

you will find that BC lampholders come in several neck threads....and they come with an inbuilt earthing terminal.....a bit of 3 core should cut it down the drop

he could solder it on himself couldn`t he....
jesus...its only a bit of warming up, flux and tin/lead isn`t it....

Would one of these fit somewhere? 1/2" so may miss 5/8".

Thanks for trying and to everyhbody else who have made suggestions.

This is the closest but need a female 5/8 that then coverts to a male 3/8 (10mm) with a hole down the middle for the flex.

Don't think I'm going to get anything. Not sure a self tapper will work as there not much room, bango won't work!

Before you do anything get it valued ....as above you say antique if that is true you will be destroying a historic piece just so your customer can use it as a lamp...... food for thought.
