Hi all,
I recently got a T8 Black with the coarse diamond wheel that's included as standard (DC-250).

A few questions:

1. Is it fine to re-use the distilled water? I don't use the grinder a lot, I just have a normal small household, so I'd go through distilled water and anti-rust fluid very quickly if I used a new batch for every time.

Currently when I'm done grinding I put the water back in a glass mineral water bottle. I filter it through a kitchen paper towel to grab the metal shavings.

2. How do you tip out the water? I find it cumbersome to unscrew the wheel (and currently I can't at all) so I just unplug it, pick it up by the handle, and kind of tip the water out like a pitcher.

3. The wheel is currently stuck on - I can't undo the thumb screw. I'll probably need some sort of pliers. Can someone suggest a good tool for that scenario? I don't want to mar or damage the screw and it kind of looks like I'd need something with large, rounded-off jaws.

4. Is it fine to use this wheel for grinding/shaping rather than only sharpening? Again I don't run a metal shop but sometimes (rarely) I have something that needs grinding down a bit. So for example, today, I bought some skeleton keys for the doors in my flat since the keys were missing. The new keys would go in the lock but when turning would grind to a halt. Took the locks apart, lubricated them, made sure nothing's grinding, turned the key with the lock taken apart to see if there are any obstructions. Nothing, smooth operation. Reinstalled the lock and the same problem occurred. Turns out the dimension on the lower left that's supposed to be 8.5, on my keys was 10mm. Went down and ground them down and now they're perfect. It was a casting error, looks like the cast was worn.

Hi all,
considering buying a new Tormek, but since I don't speak Swedish, I wonder: if I buy it in Sweden, will the handbook also contain other languages? For example, English or German.

Thanks

The manual is available in a variety of languages here.

Thanks, but I'm talking about the paper handbook. I prefer to keep my documentation in physical format. Does the paper handbook, as sold in Sweden, contain English or German, or only Swedish?

Update: I bought the machine in Germany and after I emailed the support they sent me an English handbook for free! Yay!

There are knives where the blade is ground convex [camping,hunting,bushcraft,] then there are knife blades that are ground with turns & curves. Are we talking about [camping ,hunting, bushcraft],or turns & curves?

It is scythe shaped. There's more information in the original post, and in the thread topic.

CBN isn't diamond

Oh interesting, I didn't realize that was a different material, never heard of it. I thought it was diamond. Thanks for correcting me!

You can get rounded (radiused) CBN wheels from here for example...

... but I'm still hung up on the convex edge....

Not too worried about a convex edge, if I hold the knife freehand instead of using a guide the edge will tend to become convex on its own. Thanks for the link - can you recommend other places that sell such wheels? I'm mostly looking for (synthetic) stone, diamond based sharpening tools aren't that great for powdered steel as I understand.

Hi,
I was wondering if the Tormek system was suitable for sharpening concave knives? I have a knife that is scythe-shaped. The curved blade is a 65mm long segment of a circle of radius 73mm (the angle of the arc is 50 degrees). The blade is made of CPM 3V powder steel that has been cryogenically hardened and I would like to sharpen it to a convex bevel up to a grit that is above 3000 grit (4000-6000 is fine). I am handy with tools so if this would require manufacturing my own wheels somehow and you have a suggestion, then please let me know, or alternatively if Tormek or someone else has a product that would directly suit this sort of project.

Thanks

Knifegrinders has a video showing how to sharpen concave shaped knives...

... a good place to start.  Essentially, the edge is sharpened on the edge of the wheel, that is "rounded" a bit.

But, if you want a convex bevel, unless you sharpen freehand, you won't get it on a Tormek... it does the opposite.  You could set the bevel on a Tormek, then finish it with another method to convex the edge, but there are alternatives for creating convex edges (belt sharpener for example), that may be better suited?

Thanks. Hmm, his results don't seem to be convincing, and grinding with such a thin sliver of the wheel is bound to create uneven edges. Is it possible to get rounded wheels (even aftermarket) or to reshape existing ones?
