this hook works great. Bought the tool only recently and am absolutely satisfied with it. You really don’t have to be a professional to work with this.

I bought the small cranked hook because it’s so handy. Ideal for briskly clearing out brain wood.

For this tool there is clearly the 1. Price

I can only agree with the praise. I took the hook last Wednesday from Heinz Wiedemann at the Drechslerstammtisch. I have not been turning long and have only looked over Peter Anton’s shoulder when he was explaining the use of the hook to a fellow turner (Peter – by the way, you are doing a great job of that) . ). The tool makes a super cut in the end grain and is relatively easy to guide. All in all – absolutely no bad investment !!

Best greetings
Norbert

Hello Peter ,
I do not agree with this argument, since forging results in microstructure hardening / directional grain flow. The tearing of the hooks is therefore to be sought in other influences. (possibly. constructive form respectively. unfavorable heat treatment )

Yesterday I ordered 1 set of Wiedemann hooks .

as a metal worker I have learned that forging preserves the metal structure and causes a compression of the molecular structure. So a firmer structure is created.

When shaping by chipping, the structure is always weakened.

Since I assume that the hook is read, it will not be compacted and will not have such a compacted metal structure.

The Wiedemann hook should therefore be firmer and the Wich more elastic.

I as a beginner was allowed to test the cranked Wiedemann hook and was shocked how easy (without hooking) it is to handle.

But since I do not turn large bowls or deep vases on my small red I have not bought the hook yet. Otherwise I would have had it for a long time!

Hello Ernst,
as far as I know it is the other way around.
The Wiedemann hook is laser cut and the Witch is forged.
But I can also be mistaken. I do not believe it. But I want to keep a loophole open for myself.

So I do not give my little Jet so much care. All the hollow vessels of the last time I made on it. But with a bezel. I hardly think that I have ever reached the limits of the machine for a longer period of time. That can easily take off.
Otherwise it should have become a kitchen mixer right away.

let’s agree that one hook is forged and one is lasered!

My little red one is just spared, who knows when you get one again.

Hello Klaus Jurgen,

can it be that you work with the hook in the crossbar . That would be possibly. ne explanation for the described effect. Describe at which cutting position the problems occur.

@Ernst: Regarding the tool production: The WM hook is cut from the solid by means of a water jet, i.e. by high pressure. Whether forged or cut is rather insignificant in my experience. I have as a "straight hook the Witch Tool in use and as a "cranked hook" the WM (small version). So far, none has broken off and the service life is very good with both tools. If there are material differences, they are not perceptible to me.

thanks for the clarification.

There is a lot of philosophizing about which hook is better and why, and there are many different descriptions.

I assume that it does not necessarily have to be discussed down to the metal structure when turning and a test turning with the respective tools is more powerful and contributes better to the purchase decision than any discussion.

how useful is it to buy the hook if you make only relatively small shells. 220mm diameter and 100mm high?

There the border for me as a beginner with the tube is already quite crossed.

And what about dry wood?

Is the hook only for wetwood?

if you make end grain shells, the hook makes sense in any case.
Wet or dry doesn’t matter.
The tube is more suitable for transverse wood shells.

You can certainly use the hook for anything else. Crossbar/longwood , for drilling, or just to drive a nail into the wall .

the Wiedemann hook is great. I was allowed to use the hook myself at the Drechslertreff without any previous experience. As a result, I immediately bought the hook (small cranked). One works between 9:30 and 12:00 (angular position of the WZ).
The Wiedemann hook is milled from solid, hardened, tempered and ground.

Metal science: During forging, the fibers (also found in metal) are not interrupted and the forging process makes the structure finer-grained, both of which have a positive effect on the properties of the workpiece.
When milling, the chamfers are cut and the structure is not changed.

If a CI breaks it was used wrongly or overloaded.
If you turn end grain with the tube (also possible) you turn against the grain, this will be set up, worse surface, more sanding. With the hook you turn with the fiber, this is cut off, good surface.
