I agree that I have interpreted the message rather than staying with the spoken word.
I try to be more careful this time and made a small transcript.

The question:

It`s strange. When I use the honingwheel on stainless steel kitchen knifes, I seem to blunt the edge, rather than improving it.

The response:

It can sometimes be, when you have knives with poor steel quality or that is very brittle, if any have quite a small edge, it`s very thin and then it can fall apart and that can happen when you hone it.
So, what I would recommend, to put a bit of a bigger angle, like perhaps 40 deg in total (20 deg per side) to make sure the tip of the bevel really stays together, is a god tip. That might be the case what happens.

My remarks:
The questioner did not confirm that the knifes being sharpened were indeed made of poor steel quality. Knifes rather than only one knife were mentioned. However no more details were communicated.

Sebastien mentioned poor steel quality, followed by describing a small and very thin edge.

My point is, that poor steel quality will not allow making knives with very thin and small bevels. However modern high quality stainless steels allows making such knifes with thin geometry and the majority of todays high end knives with stainless steel is having the described geometry.
Those knives with thin geometry have a very good cutting performance.

Sebastiens conclusion that knives with very thin geometry are made of poor steel quality does seem to be questionable.

His suggestion to sharpen such very thin geometry knives to 40 deg total is questionable as well.

If Sebastien would have asked back with what steel type and knife geometry the questioner had experienced the problem of dulling during honing, we would know more.

I was very disappointed hearing that Wolfgang suggested sharpening highend Kitchenknifes with hard stells to 20 deg dps (40 deg total). He had confirmed that such knifes otherwise would be prone to chipping when sharpened by a T1 at smaller bevel angles.
This sounds like a no-go for users of such knives and I hope this can be clarified.
Can high end Kitchenknifes with very high HRC and thin geometry above the edge be sharpened to the approx. 12 deg dps, where such knifes cut best?

The max. power consumption will be in the area of 200W.
In idle, the power consumption is much lower. Unfortunately, I do not know that value.
The actual power consumption depends on usage. How long is it running idle, how long under full pressure sharpening.
You could ask Tormek customer support for average numbers.

This could help

I'm using a laser goniometer as well and agree to your assumption.
There is no guarantee to achieve an accuracy better than 1 deg.
It may very well be the case that you could adjust your Jig to 0,5deg. However, I strongly disagree that you could sharpen a knife with your Jig to that accuracy.
The good thing is that is not important.
Your Jig is a great solution for sharpeners who do not want to use the other available solutions. It seems to be simple and straight forward in using it. My only disagreement is the continued misconception regarding the achievable result in bevel angles and the repeatability of that angle on the same knife at another point in time.

If you can demonstrate that, if you had sharpened a knife to a certain angle, used it until dull, and then sharpened it again with your jig.
Marking the bevel with a black marker bevor sharpening would reveal if you could hit that angle exactly.

I would give a big WOUGGHH for that result.

For the time being, I like your work and the person gifted with it can be proud.

the accuracy meets the requirements we had, within approx. 0.5 degrees.

How did you measure the bevel angle of a knive after sharpening to verify that accuracy?
 

As per the "The Forest Service Ax Manual - one moving part", 17 to 21 dps is suggested for the bevel, wich is 34 to 42 deg inclusive.
However, an microbevel of 25 to 32 dps (50 to 64 inclusive) is recommended in addition. 

However, you are talking about hatchets, not axes. I should read more carefully.

You cannot view this attachment.                                           

........ It now measures about 42 degrees, and cuts paper.  Not quite yet at the recommended 20-35 degrees, but getting there.

Not sure if I understand correctly.
I thought if one is using the WM-200 touching the side of the hatchet, the included angle would be measured. So the 42deg would be equivalent to 21 dps?

I would agree that it is desirable to meet the intended angle with not more than 0.5 deg deviation.
I have played a bit with the calcapp Knife Sharpening Angle Calculator to find out which deviations in Projection Distance or Distance to the grinding wheel would cause an 0.5 deg error.
For a single measurements, up to 0.7 mm deviation is allowed.
In case that both measurements are affected by an error, it is sufficient to measure both data with an error of not exeeding 0,4 deg.

An measurement error not exeeding 0.1 mm would only be needed if it is planned to meet the desired angle with an error of less than 0,1 deg.

While I agree that +/- 0.5 deg error can be achieved with the Tormek system, I strongly believe that an angle error of less than +/- 0.1 degree cannot be repeated on a Tormek system. Even when Projection Distance and distance to the grinding wheel would be measured without any error, the sum of all other errors and tolerances would cause that the resulting angle cannot be maintained repeatedly.

I therefore, do not see any benefit in measuring Projection Distance or Distance to the wheel with extreme high precision.

Using the save as draft function ist the right way. Leaving the computer without saving the text is risky. An internet connection can be interrupted at any time and there is no guarantee that the automatic login after the interruption always succeeds.
A longer default time helps, but does not prevent data loss completely.

I'm confident that the admins are aware of the potential security issues of integrating Tapatalk to a forum. I suggest to stay away from it.

I have visited their website http://www.burrbenders.com and could not find such zero Bess claim there.
Non of the videos presented at the website shows zero Bess readings.
However, they show contact information and I feel it would be fair to ask them directly.

I do not like the term "temporary glitch in the growth process".
A malfunction is a malfunction. If it affects customer support, I call it a significant malfunction.
I agree with you that Tormek will certainly fix that and I appreciate their efforts to provide an alternative solution to mitigate the problem. There is not much what Tormek clould do about it for the time being.

A good solution could be convincing the Tormek Team to prevent such issues before selling products or fixing it after sales.
I strongly believe that Tormek is aware of the issue and just have other priorities.
