Hilfe: What is this tool?

[axongraph]

Hello,

I am sorry for writing in English, but my German that I studied many years ago in school, is quite weak now, it has not been used lately ((

But your answer would be much welcome even in German: I am sure I will be able to understand it somehow.

I hope you can help me find out the purpose and the use of this nice hand tool (see pictures attached) that was made many years ago by the company Zettler in Schwerin.

I suspect that it may be a grooving plane (Nuthobel) used possibly in woodworking???

But what was is used for?

And how was it held?

Why does it not have a flat (plane) surface that would keep its movement straight?

Any idea would be much appreciated.

Thank you in advance for your help.

Das koennte ein Nuthobel sein, mit dem der Boettcher die Nuten für die Fassboeden ausarbeitet. Das wuerde die runde Hobelsohle und den merkwuerdigen Griff erklaeren.

never seen something like that.
It should be a grooving plane, but for whatever?I think the half-round adjustable something leads the tool. but I have no idea for what sense.
Maybe our "old-faishoned-tool-crack" Ottmar aka edelres, who's nearly your neighbor, knows anything about that.
The tool is quite small, right ?

Thank you all for your kind responses : ))

It seems that this tool then could be used to work on ROTATING OBKECTS, and NOT ON FLAT static surfaces. This is an interesting idea and it would explain why the flat "sole" of a normal plane (Hobel) is missing here!

The round space in the copper "slider" would keep the tool from moving sideways if it was gliding on some "rib" of the rotating object (the question is: did barrels have such ribs?)

Also: special thanks for the address of the original manufacturer!

Mystery tool

Good evening axongraph,


The technique used to fabricate this tool, compared to similar craftsmanship I know, I guess it was used/produced around 1850.


I don think it was used on a barrel, since it would be very hard do spinn a barrel around in such a precision, do use this tool, wit accuracy.


I'm almost sure, it was used on a lathe, to cut a groove, maybe in variable with, next to a half-round ring on the turning object, the half round ring could be a part of the chuck,to guide the tool on the turning piece for exact grooves, the distant of the grove can be set, the depth of the cut I believe was fixed or set in increments to get a smooth grove.


It is a very interesting reminder of the craftsmen using tools like this one, approximately around 150 years ago.

Hi, Ottmar,

Thank you for the detailed explanation!

Although there are still a few questions that remain to de discovered, I am a liittle afraid of flooding this German-speeking forum with English text. But everybody was wery helpful and patient, despite the weakness of my German language skills.

Very best regards, and thanks again for your ideas.
