If you have, or know someone with a 3D printer then you could get one of these printed for you.

Tormek produit beaucoup de vidéos sur sa chaîne, Tormek Innovation et je crois qu'ils ont également des versions françaises de leurs vidéos. Recherchez leur vidéo sur l'affûtage des couteaux. Ils ont beaucoup de trucs et astuces pour aiguiser les couteaux.

Quote from: Ken S on October 28, 2024, 01:08:59 AMI am not convinced.

In my experience motor overheating is affected by several factors. One is the load on the motor. If you are sharpening a lot of generic kitchen knives which only need a freshen up then the load will be low and unlikely to overheat. If you are doing some heavy lifting such as cleaver or reshaping or removing chips then the pressure will be higher and place more load on the machine. Another one is ambient temperature. If you are in the tens or teens then the motor is unlikely to overheat but if you in the high thirties then you are much more likely to overheat.

While the average home sharpener who is in a airconded or cooler environment mat never have an overheating issue. A professional in a warmer climate may run into issues.

What wheel are you using? These use A2 cryo steels. If you are using the SG then they will glaze your wheel in no time and you will have to continually re-dress your wheel. If you are using diamond or CBN then you should require less time, but honestly you probably need to start of on about 80G. In any case the SG is Aluminium Oxide and too soft for the steel.

Quote from: Royale on October 27, 2024, 08:51:16 PMYou may run into issues if you get a surge of customers and the T-1 keeps shutting down to cool off.

That would definitely be inconvenient!

I use the SG for regular knives, carbon steel chisels, plane blades, and axes. For HSS plane blades, planer blades, chisels, and Japanese knives I use the diamond wheels. The SB would also be fine but I bought the diamond wheels.

Axminster in the UK sell them and they offer free shipping over certain value, not sure what it is in your currency.

A few more notes.

If you buy the SG- which I recommend strongly, this will do almost everything you need, then also get the SP-650 grader to grade between fine and coarse.

For removing chips I use a belt sander (keep a water container handy for keeping the tool cool) and gently work away at the primary bevel until you have removed the chip.

Make sure you remove the wheel between sessions. It is easy to get the wheel stuck if you leave it on.

Keep the machine lubricated. I use the adage a little often.

Seek out the videos recommended by Ken from the official Tormek channel. Watch those relating to chisels and plane blades first, obviously. They are well worth the time.

Be sure to come back and post any more specific questions here. There are plenty of knowledgeable, experienced  and helpful people ready and willing to help.

The T1 is an excellent choice for sharpening your standard kitchen knife. The diamond wheel and composite hone will give you more than satisfactory knives of any hardness.

On the down side it will not handle specialty knives. You are pretty much limited to standard shape knives. You may find you loose custom to sharpeners who offer a wider range of services. You will also not be able to repair chips or breaks. These take additional equipment.

If simply sharpening your standard kitchen knife is what you are after then the T1 is ideal.

As for price google knife sharpeners in your area and see what the going rate is.

General Tormek Questions / Re: KS-123 For Chisels

Quote from: tgbto on October 04, 2024, 03:04:11 PMSo you'd have to measure the protrusion distance ...

Even then it would not be accurate since the jig is specifically designed to use with the knife jigs which center lines are sitting a specific distance above the bar. I have not checked but if the Square Edge jig is a different distance above the bar then the geometry will be out.

Quote from: Royale on October 05, 2024, 11:37:06 AMI personally find it quite ironic how people can discuss (and argue) about how various types of natural stones need to be used for sharpening a knife

My training was electronics and I have been interested in Hi-Fi all my life. It is the same there but far worse. Some of the claims are interesting to say the least!

Here is a really good demonstration. I have linked to the relevant chapter. She uses a head (curved) knife but I use a straight or right hand angled knife.

In thin instance I skive the upper of one end and the lower of the other end to zero thickness for the distance of the overlap.

Quote from: iSharpen on September 28, 2024, 02:34:10 AMI see lots of YouTube users struggling with smooth movement that I was taking for granted so I thought about it and came to the welding conclusion.
Yes, like any skill, it is down to practice. I have spent my life making things so using the Tormek was almost instinctive. I am also an armature musician so I am guessing that that also helps since it trains hand eye coordination. I have friends who never did anything really practical and I could imagine that they would struggle.

Quote from: iSharpen on September 28, 2024, 02:32:14 AMDo you print your own wheels?
There are a couple of printers in the family, my son and son-in-law. The first couple the pins broke off since they were fragile. I drilled them out and used short screws in their place. The next time I'll get them to use 100% infill around the pins to see how that goes.

A skiving knife from DS Horne is relatively cheap and they are pretty easy to use. The trick is keeping it sharp, but I am guessing that will not be a problem  ;)

Will do when I am  down your way. Not sure when, I don't go that way often.

Knife Sharpening / Re: Titanium Cutting Boards
September 30, 2024, 02:27:31 AM
From a google search "Commercially pure grade 1 titanium has a Rockwell B Hardness of 70 – 74"

Seems like a gimmick to me. I would stick with wood myself. Relatively cheap, anti bacterial, easy to clean and maintain and low impact on knives. Also looks good IMO.

If it is softer than you knife the surface will end up with scratches all over it. If that is the look you are going for ...
