This verb age should have been with the photo above.

The name of this item describes the tool. its robustness indicates an industrial purpose. The photo shows my use of it to reduce the size of hexagon heads.

Any info would be most welcome.

Thanks. Paul.

I don't know what it is, but it is certainly a nice one!

It may not help, but Erma are / where a manufacturer of firearms (rifles) in the 60's, and maybe later.

Alan, thanks for the reply. The item is a horizontal mill for second operations, made up of a very solid base with a powered vertical slide and a 2 way table.

Do you know if the Erma you mentioned were at Wembley?

So that is what it is! Erma rifles is extracted from the "not so good anymore" memory!

".... I have one of those"

Do you mean an Erma rifle, or not so good memory!

I don't believe there is any connection with Erma Werke the firearms company, as they were German, and the background to ERMA the machine tool company is a Jewish family!

I wouldn't mind betting (see link) that the ERMA name came from an acronym of ERna and Erich MArx, Theo Marx's parents, that started the ERMA company.

David, thank you, a very interesting LINK. You could well be correct in the derivation of the name.

The link puts some very interesting history behind ERMA smiley

I bet Tony Griffiths at lathes.co.uk would be very interested in your tool - and may well be able to help with more details.

I think there was one of these on ebay recently or was it this one that you have now painted? Probably a screw head slotter and other small repetitive job machine.

SEC-OP-MIL - could that be short for 'Second Operation Mill'?

Second operation lathes had all the bells and whistles removed. They were used to keep costs down in production work to avoid swapping tools, chucks etc on the main machine, perhaps a fully populated capstan or turret lathe, that did most of the work. Perhaps the same idea was applied to milling machines, this one being a horizontal mill with a single axis.

I'd say there's a strong clue in post #4 wink 2

I can see what looks like a modified keyed chuck with a small indexing plate at the back. There is also a very dinky swarf bucket. But I can't see a hexagon head. Am I missing something?

Bazyle, not a recent acquisition, I have had it for some 20 years.

 

Alan, the vice ,indexing chuck and swarf tray are all items I made to use the tool. The mandrel has 2 cutters with a spacer to suite whatever across flat dimension I want to produce. In the photo. there is nothing shown in the chuck. It can of course be used with end mills.

Thanks for the responses.

Paul

I thought post #2 gave the game away: "The name of this item describes the tool."
