Tormek T-1 and T-2 / Re: Just got my T1 - question ...
Last post by Ken S - February 01, 2024, 12:37:31 PM
Welcome to the forum, Ted.

Excellent reply, Tgbto.

Mats is my "go to guy" in support. He is very smart, dedicated, and his employee number is 5! He has been with Tormek for thirty five years and I am sure has done every job in the shop.

In addition to the general purpose, "do everything" models (the T8 and T4), over the years Tormek has produced a series of specialty models for sharpening knives. Until the T1, these were all designed for commercial use by chefs and restaurants. The T2 is the latest rendition of these models, utilizing the new diamond wheels and composite honing wheel technology, as well as a special new angle setting guide.

The T1 is the first model designed specifically for home cooks. This serves the needs of a very large niche of users, the home cook. Whereas the general purpose models must routinely tackle very dull or damaged knives, most of the time the T1 will be used in the kitchen to maintain tip top sharpness for the users knives. As demonstrated by Samuel, Tormek's CEO, he keeps his T8 in his garage and his T1 in his kitchen. He chooses to do touch up honing before every cooking session. His knives are very sharp. I met Samuel last August. He is a caring, methodical person and the condition of is knives reflects this.

I would not be concerned with the warmth of your Tormek. After initial sharpening, regular touch ups will be quick and give you very sharp knives.

It looks like it's normal :

See here on the Tormek FAQ, the search result returned by "T-1 warm".

Something I missed when I first looked at your screencap.... To further comment on the meaning of the angle in TormekCalc, maybe it's not obvious in german, but in english it goes :
declared angle/measured angle/ground angle
  • "declared" being the angle given by the manufacturer (e.g. 16dps for most shun knives)
  • "measured" being what you read on a goniometer, or better, what you get from bevelCalc with the sharpie method and measuring the top-of-usb-to-wheel distance
  • "ground" being whatever you decided to grind using - most likely - TormekCalc, based on either the angles above, or Wootz' advice, or your own reasons.

So, rare exceptions aside, you shouldn't have 20dps deklariert and 10dps geschliffen.

Tormek T-1 and T-2 / Just got my T1 - question abou...
Last post by tedv - January 31, 2024, 04:38:47 PM
Hi, just got my T1. I already have a T7 ( ~ 15 years old ).
So all is fine with the machine. Sharpened a few knives and its much more convenient than setting up the T7, and having to grade the stone every time between knives (going from 220 to 1000).
Edges are good - they're a bit more coarse and have more 'bite' than a finished & polished edge on the T7 but that is expected.

I noticed that the device gets a bit warm after a few knives - is this normal?

I'm not sure what you are referring to in the drawing, but Delta (as the greek letter) in TormekCalc is the bevel angle in degrees per side.

Z6 is the declared angle, so subtracting half the total blade angle makes sense (dividing I6 by 2 to get the half-thickness in the process), but why divide the difference again ? It looks to me like you're computing :

((Delta-(BladeAngle/2))/2)
???

Quote from: tgbto on January 29, 2024, 05:16:27 PMHi. In any case, if you take the arcsine of (J6/2)/I6, you already have the angle in dps (degrees per side), which is what TormekCalc uses, or half the total edge angle. So why would you again divide the result by 2 ?
I divided with 2 because in my TormekCalc V2.70 the raw is named cutting angle and not grinding angle.

Hi Jan,

Thanks for the download password and the step by step description. Much appreciated!

I will start using the sheet and will share my findings/questions with you later on.

Best regards,
Marco

And as we said before, and as explained in the video, as TormekCalc or Dutchman's formulas are based on projection distance, the (apex) angle you get is independant from blade thickness. However the beam of your laser goniometer has a nonzero radius, so the reading you get will essentially be scattered between the apex angle and whatever angle is measured as the edge of your beam hits the concave grind made by the wheel. The latter angle being higher than the apex angle. This is more likely to happen on a thick blade where concavity is discernible.

  (What is "brideness"?)  The sharpening angle is not based on this.
