Looking for help with a family heritage cambrian no1 b/136. My wife's grandfather was a winder in the Rhondda and this lamp has been handed down although not from his period as its dated later as 1952. It's in good condition but I cannot undo the base. It has about 4mm of movement then hits what seems like an internal stop. Most videos show it just being unscrewed. There is no external magnetic lock. Any ideas would be welcome. Thanks IP: 85.210.102.39

Are you sure there is no magnetic lock on the base of the oil vessel? Can you post a couple of pictures? IP: 84.92.35.248

The pictures have come up a bit small (not sure they have been posted in the correct format). Looking at the picture of the base of the oil vessel, on the left hand side, close to the edge looks like the magnetic lock. It's a vertical, spring-loaded 'plunger' that engages in a set of teeth in the glass retaining ring. You'll need a powerful magnet, and probably need some gentle tapping to get it to move as everything is likely to be a bit seized up in there.
Once it's open you'll be able to either dismantle the lock to remove the plunger or spring to stop it re-engaging, or get a thick cardboard or metal 'washer' made up that will sit between the oil vessel & the upper part of the lamp.

Hi.
Thanks for your help. I thought Id posted a reply but it doesn't seem to have appeared. I've added some other pics which hopefully expand. I had thought the stop might be part of the solution but it appears pinned through the side of the brass ring. I wondered if the shape fitted into a fixed plate like male to female so that the lamp man could have two hands to turn it (if something like that existed). I'll have to go and investigate magnets...
Thanks Ian

Ian, you need to touch the magnet to that iron stud in your picture. That stud then conducts the magnetism inside to the plunger and pulls it down to release the top ring.
As mentioned above, it will probably be a bit seized so give it plenty of wd40 into the top joint to dribble down to the mechanism over a couple of days.

To see what you're dealing with, have a look at ebay item 264735073136

https://www.ebay.co.uk/itm/Genuine-Aluminium-Welsh-miners-lamp-old-Thomas-Williams-of-Aberdare/264735073136?hash=item3da370a370:g:Cm0AAOSwocFewr3W
(pictures 6 & 8) which shows the two parts of a similar lamp's lock - #6 showing the 'teeth' & #8 showing the lock plunger (l/h side of pic) coming out of the upper surface of the oil vessel, looking at the score marks on this lamp it looks like the plunger has been trimmed down to stop it re-engaging - a large stiff cardboard/plastic/metal 'washer' would also do the job without having to butcher anything.

Even more helpful. I can see the issue now Looking briefly at magnets I'm assuming there's no issue with polarity? They seem to be offered with one or the other. I always thought they had both...... IP: 85.210.102.39
