This might work for you Ian. My mother in law had them fitted to front and rear doors. It allows the door to be locked on the inside but still opened with a key from a key safe.

Thank you John, I'm a little, but only a little, nearer understanding.

David

Many thanks for the replies

I can imagine that the gas that is being used to form the plasma ( if that's what it is ) in a fluorescent tube is the gas that it is filled with but what about the plasma in a plasma cutter? Is that the surrounding air?

If it doesn't show, I'm at the limits of my knowledge here

Rather than hijack the thread that started me wondering, I am starting a new one.

When we talk about the other three states of matter, we can state what they are made from i.e. water, stone, air etc. Can we do the same with plasma?

Just wondering

Hello Martin, I've had some success by storing the paint tins upside down. Just make sure the lids are on tightly!

David

Not just me then

I don't know about laser cutting but I do have some experience with sheet metal. They could be made on a cnc punch machine which I have seen produce some very complex shapes.

David

Thanks Jeff.

I've resurrected this post in order to say thank you for all the advice.Using quite a number of the suggestions that I received, I now have a working lantern pinion

Many Thanks, David
