What are these?

[Maker]

They're solid copper, the total thickness is about 1/4" and the designs are milled out to a depth of around 3/32". I'm guessing they're used to mass produce signs but I've no idea how they're used.

And secondly, this fiber optic type thing;

No, you haven't seen it in Ann Summer's 50 shades' range.



Both been in dad's loft for years, he can't remember where they came from. If anyone knows anything about any of it, I'd love to know.

Hi, The plates look like printing plates.

Just seen the fuses on the bench in the last picture, are you going to try your tig on single phase?

 

[bigegg]

Printing plates, or embossing plates.
No idea why copper, tho - is there a reason one wouldn't use a steel plate on (aluminium?) signs?

 

[Wallace]

Perhaps the copper plates are for spark eroding tool steel to make dies so the signs can be pressed.

 

[bigegg]

An idea:
Is there any sign of heat damage to the copper?
Could they have been used to heat set the design? either heat set ink, or vacuum forming?

 

[WorkshopChris]

Could possibly be for Hot Foil Blocking/Embossing.

Hi, The Ann Summers implement is part of a fibre optic light display, the big brass end has a light source which transmits the light down the fibres to give a small pinpoint of light on the end of each tail. There was a couple of cars in the 70's that had this for dashboard and heater control illumination, Jaguars was one I think.

Copper certainly suggests some form of heat application.

How does a lad like you know about Anne Summers?

Make a Christmas light with it.

I think they may be for producing plates for vehicles transporting HazChem.

He's migrated from the Freemans catalogue lingerie section!

Ooh, didn't think of that.

I was going to ask here if anyone knew what they were for but I forgot to.

Any ideas? I'll take a close up of a label later, I think the big ones are something like 40KA.

That was my thinking too. I can't see any signs of them being damaged or worn away though it's possible they were never used.

Spent too long talking to you lot.
