Interesting 3D.
So edge retention seems not to be compromised by the different honing methods.
So any potential over heating by using the WSKO leather belts seems not to affect the edge retention.
What is of interest to me is how quickly the sharpness decreases with these pretty standard kitchen tasks?
#32
And there was me thinking you were going to go all Vadim on us with that coloured temperature sensitive whatjamecallit that he used in his heating tests. What we get is a carrot.
Tee hee!
Go for it 3D!
#33
I would be very interested in any results 3D, as like you I hone on a WSKO blade grinding attachment at the lowest speed.let us know what you find.
#34
What is also really good about Per's angle setting tool is the confidence it gives in using with wheels of different diameters, for example from a CBN to the leather honing wheel and then maybe to a slightly larger than 250mm paper wheel on a different machine (there is wriggle room to go above 250mm).
So much simpler than inputting data with differing parameters into a calculator then fiddling about with callipers and adjusting USB accordingly.
And I totally agree with CBX, it feels much more satisfying to see that angle clearly on the scale than trusting that a measurement is right.

Yay! Glad that helped Darita.
I suppose that the paper wheels are quite a departure from the slow, even grinding work on the Tormek and it takes a little while to gain confidence, especially as there is an element of jeopardy in the higher speed revolutions.
Personally,I have all but given up on chasing sub 50 Bess scores. Too much time and fiddle faddle involved which can't be justified to most clients. Would only bother with a high end knife and by agreement with a customer.
Let us know how consistent you can get results with the paper wheels. I have had mixed results and don't bother with them much anymore.
#36
When I started using paper wheels I had the same problem and it was a little worrying. So I think I got quite tentative which only made the problem worse. I contacted Vadim who instructed me to use greater pressure than one would think ( can't give you a quantitative figure for how much pressure).
Anyway, from that point on the process became much smoother with little or no chatter. I think there was a bit of a learning curve and a bit of 'running in' for the wheels themselves.
#37
Thanks for the advice.
Don't worry,I will be cautious if I come across an apparent bargain!
#38
Thanks CB, as I said earlier Wootz recommended 1400 RPM for paper wheels.
Darita, this is the point. I don't think running a paper wheel on Tormek would be very effective at all. They need those higher but not too high revs to work.
#39
I'm pretty sure Vadim recommended an RPM of 1400 for paper wheels.
#40
You just know I'm going to agree with the last 2 replies.
It seems Tormek are making it difficult for sharpeners who sharpen lots of knives where time and convenience/efficiency is really important.
And it's so glaringly obvious. Ho hum.
#41
Think this might be one for you Ken. I'm looking into getting a used Tormek supergrind and was wondering if it would be possible to use new honing wheels and grinding wheels on these older machines. There is a chance I can get one for a good deal and would consider it if I can upgrade it with new version wheels and usbs?
#42
Hi. This is surely a question for CB to answer. I think he must be busy as he's normally fairly active on the forum.
Your question is not entirely clear. For USB to stone measurements simply input the stone diameter and jig projection into the calcapp and it will give you an answer, will work for FVB or normal edge leading grinding.
If I'm right in concluding that you want a USB to casing measurement then calcapp can now provide that but I think you will have to input some constants measurements for that. Straight forward for grinding but maybe a bit more complex for the FVB, as depending on the FVB you have you may have to take some accurate measurements. I'm sure calcapp should guide you through this. If it doesn't then I'm sure CB will help you with it.
Sorry to hear you having cognitive troubles. Hope it gets better soon. Good luck!
#43
Yes agree with Ken. Don't do anything silly like hitting it with a hammer or grinding your shaft (?!). I know it's frustrating but Tormek support will get this sorted for you.
#44
Ha anyone used this ( LA 120) to deburr serrated knives?
If so is it th thing to use or would a tapered felt wheel be better?
Thoughts please, thanks.

Knife Sharpening / Re: Rock hard felt wheel

Thanks again everyone. Lots to think about.
It seems that the jury is out on the felt wheel then.
Perhaps it is best left for harder steel or quality knives ( as Vadim termed them).
The interesting thing with that is that many of Vadims protocols for these types of steel forgo the felt wheel and rely on exact or sometimes a very slight reduction in angle. These steels fall into the negative burr category I think?
