Introduction to a test rig, preparing for the 2391-52 exam. GEE
A short video introducing the test rig I’ve built to prepare for the 2391-52 practical exam. For a lot of reasons a test rig is a useful device for any electrician to have, but preparing for the exam conditions is a helpful step towards success for the 2391 practical.

Sharpening Husqvarna Automower blades with a Tormek T8
Can you apply anti-rust WD-40 to CBN Wheels lubricant?
Qs pls when im swapping wheels of different sizes, even though i calibrated with angle setter, it still started a new bevel, looks like their angle setters are not precise when using it on different size wheels while sharpening 1 knife. Any thoughts?
Have you watched my Tormek angle-setting video? The answer is in there, along with further details…
How do you increase height from handling bar? My bar tends to be super low when sharpening to 15 degree per site on bigger knife
If you are sharpening very large knives, you might need to buy the extended USB (Universal support bar). Have a look at your nearest tormek supplier for that.
@greatedgeltd thnx
How do you measure diameter of a wheel?
With callipers. You can see exactly what I use in my Tormek angle setting video
@greatedgeltd thnx
Can you show using cbn side of the wheels used, thank you
So i found 2 different cbn, one that doesnt have side plating, others do but 50$ more expensive, would you recommend wheel with side plating?
It really depends on your needs… Side plating gives you more flexibility but based on your sharpening needs you might never use it…
@greatedgeltd I see, so like correcting chipped knife for example, is side plating necessary for that?
@ia6980 I would say no…. All of my chip repairs are done on the main surface… an example where side sharpening is better is for Scandi grind…
Good info 👍
So do you ever use sg-250 and sj-250? Or are they all cbn now?
Good tips thnx
Reality is, few cuts of veggies or meat on that razor sharp, and razor sharpness is gone, your test will be doubled, it doesn't matter what number you get on this scale, most important is how long can your knife retain sharpness. Factory sharpness, although not scary sharp, but somehow tends to retain sharp edge for much longer than using sharpeners even like ts prof or kme, after which its razor sharpness but they dont retain sharpness for too long
Sehr gut, kann ich als alter Hase noch was lernen 👍
Qs pls, do you think it would be acceptable going from cbn 400 to SJ-250 japanese stone? I just wonder if cbn 1000 is necessary or if it can be skipped?
So you didnt memtion which ultimate wheel would you choose?
Thank you so much for creating this video lots of good information
What do you think of using cbn 400, cbn 1000 and then japanese water stone sj250? How long does it take to compensate for difference? To get same angle?
If you are sharpening with that method you are already committing to a fairly long process, so the extra time to set the SJ correctly won’t really be a factor. You’ll get a very nice looking finish that way..
@greatedgeltd why would you say long process? Which one would be faster? I heard if u use sj250 honing with leather is not necessary?
@@greatedgeltd what grit do u finish your knives with? And do you strop them afterwards?
What do you think on ordering cbn grits, 80 grit, 400 grit and 1,000 grit...is jumping from 400 to 1000 acceptable?
I would start from 160, not 80, unless you have a very worn or damaged knife. It will be easier on your knives and wear less steel. But otherwise it’s fine to jump from 400 to 1000 because you are just refining an already established bevel, so there isn’t much strain on the 1000. I am still on my original 1000.
@greatedgeltd awesome, thank u, i ordered 80 for repairs mostly of like damaged or chipped knifes, or do you think 160 might work for it just fine?
Thank you for posting this
Id prefer videos where youre sharpening with both of those. Also qs, you used 2 wheels on tormek? 600 and 1000 grit? Or did you use grading plate to change grits on tormek?
I decided not to show the full grinding because there are so many other videos already showing that process… For efficiency of time, I skip to the punchline. But elsewhere on my channel I have videos of the full process with Tormek, and the full process with the Worksharp if you want to see how I do it…. Thanks for tuning in.
P.S Tormek sharpening was with 3 grits… 160, 400 and 1000 (CBN).
@@greatedgeltd okay thank you
So why you use diamond stone and not sg 250 that comes with it? Sg250 sharpens faster I heard? But u need to level wheel once in a while. Diamond wheel on other hand I heard doesnt sharpen as good after some use (it starts sharpening faster and after use steel removal goes down so takes longer ) can you give your opinion on this in your experience pls?
here you go - you might find this video informative: th-cam.com/video/-ap5QRR8Kyk/w-d-xo.htmlfeature=shared
@greatedgeltd thanks
12 degrees? Not too long lasting. I see at bunch-0-stropping in your future.
No necessarily…. Have you seen my ‘Which angle is best’ video? th-cam.com/video/1Su3IUXuuLY/w-d-xo.htmlfeature=shared.
@@greatedgeltd Thanks for the link very informative.

That's great thinking and I'm glad to see others both recognize and spread that vital information. However, it's important to note that by the time you feel any heat in the blade, you have gone way past the point of overheating the very apex of the edge. The material at the apex is so thin that it will overheat long before you can detect the rise in temperature with your fingertips on the blade, even relatively close to the edge. There's some good evidence out there demonstrating this. That's why I maintain that the best course of action is prevention by making sure belt speeds are low enough (and blade speed is sufficient as you're demonstrating) so as to never allow the heat to build up significantly or, if the setup allows, to use a wet grinding system. Obviously, the easiest way to tell if you are overheating the edge or not is by evaluating its performance and seeing if it is in line with the expected behavior for such a steel, heat treatment, and given blade geometry. There's some good channels out there that do rope and cardboard cutting tests which really show how much performance is lost with factory high-speed dry grinding messing up the blade's HT/temper.
For me, the wheel in the fwd position still adds about a degree due to slack. So if you want 20, set it at 19. You dont want to press the blade into the belt but you dont want it gliding either. Should be just enough to see the belt deflect a degree.
Consider a different camera angle the next time you make a video. All I got out of this was a perfect view of the back of your left hand.
I agree - the camera angle is terrible. Because I do so many single-shot videos I don’t spend a lot of time on editing and didn’t notice until it was uploaded. I planned to delete it and re-shoot, but it’s consistently one of my top-viewed videos and 96% likes vs dislikes (in line with my channel average). So in the end I’ve decided just to let it ride, and hopefully it doesn’t put too many people off. Thanks for tuning in and also for the frank feedback. Happy holidays!
A REAL PRO BEST WISHES KEEP UP THE VIDEOS
Thanks very much! This one didn’t get a lot of views so I appreciate you finding it. Merry Christmas.
tormekian guide... that even should not exist in sharpening world... stop ruining knifes... no profesional cheff would not give a knife to sharpen on this bs machine..
Thank you for your candour. Despite your strong opinion you must have at least a slight interest in Tormek, or else you wouldn’t be watching TH-cam videos about it. Thank you again
I got silicon carbide wheel, I keep at coarse, the regular wheel that came with tormek T8 i keep at fine. I have regular centering knife jig, large centering knife jig, axe jig, small knife jig, jig for chisel, and scissor jig. I like how fast i can now sharpen kitchen chef knife. I will be using the T8 for my second sharpening booking on 30 Dec 2024.
Nice to hear someone talking about speed and Tormek - I agree that in good hands a knife can be prepared very quickly. Thanks for tuning in.
I am trying to start a sharpening service in Surrey. I have a Bess Tester on the way from the US. I would really like to do a 'before' and 'after' for the customer on better knives. Thanks for your videos! I just received my Tormek and have a 1 x 30 en route from China. I have been using wet stones for the past 25 years but have never used powered sharpeners. It will be interesting.
That’s great - nice to know of another local sharpener. I’m in West Sussex and there is also @simonwells6977 in East Sussex. Good luck with the startup. Tormek and 1x30 is a nice combination. If you find a nice way to convey before and after BESS scores to customers I’d love to hear about it. In my experience it’s often a difficult one to explain succinctly.
I tried to explain it to my wife. Lots of nodding but I don't think she got it. Most people consider knives sharp or as my wife describes my knives 'blunt'.
@@brianpage1886It one advantage of the paper slicing - easier for everyone to understand. Most knives are brought to me via my drop box so I don’t get to meet the customer, but when I do see them I try to do a ‘before’ paper slice, and an ‘after’ one when I hand the knife back. That usually makes an impression.
Thanks for video! Just to correct you a bit. I am in south Northamptonshire not East Sussex! And I sharpen under the name ‘The Sharpist’ I agree with your points. I’m using the Bess tester less and less these days. Slicing thin paper can often tell you so much more about a knife edge’s condition once you get a feel for it. Oh and of course how easily it shaves arm hair! But I suppose we shouldn’t be promoting that!
Thank you, Simon. Clearly I need to spend a bit of time sharpening my memory ;)
Nice! I do something similar, I have different color tubs for each customer, and as I sharpen a knife it gets an appropriate sized / matching colored sleeve that I’ve laser cut from poster board. Sleeves cost me $.02. Then the whole bundle of knives gets wrapped in packing shrink😎
I like the idea of coloured tubs! That way that can be stacked up, or stacked away when not needed - good solution!
@@greatedgeltd- I use tubs too but I do like the vertical magnet idea as well.
Any idea how long or how many knives a WS belt lasts you? Kinda curious how it compares to other belt systems
Good question - I don’t really know how this compares to others but I change my Extra Coarse belt every 15 knives or so. As soon as I notice by grinding time is starting to extend due the belt I swap. As the saying goes, time is money so I don’t want to be wringing out a few extra knives by spending more time. However, because I use the Extra Coarse to do all the heavy lifting, the other belts last a very long time… Hundreds of knives each…
@@greatedgeltd Oh okay thats pretty comparable to 1x30 belts actually. Which is funny since they are twice as long :D
What is cbn ? And what diff with diamond
You’ll have to check wtih google or other people cleverer than me to understand the compositional differences of CBN vs Diamond, but I explain some of the performance differences and requirements of each in the video….

Ha, thanks for the advice about the Worksharp. Unfortunately it performs too well for me to pack it away. But I know I’m in a rare camp of sharpeners that uses two systems…
And I’m living in West Sussex, in the UK.
@@greatedgeltd .... Hi .... is it a secret as to what country you live in ;) ? As for the Work Sharp as you get older you will get wiser .... I gave up using both systems 32 years ago , I've been professionally sharpening knives for 50 years.... if you listen to what you said about the machine and to other experienced knife sharpeners, you will find the answers, the best time & money saving advice I can give you is to learn from other people's experiences & mistakes .... nothing beats it, unfortunately we don't get to live a second time to do things differently or better.... A majority of the time if you learn to listen and watch you can gain years of experience .... ( Decades) more than if you try and work things out by yourself .... correct me if you think I'm wrong .... I'm always willing to learn from someone else's experience or mistakes....

@ Thanks very much - feedback is always appreciated especially when given so thoughtfully as you have done. Just for information, it’s a deliberate choice to set out my videos the way they are - very pared back with just core information given… No fancy editing or show. It’s a bit different than what you refer to about customer service or sales, because we don’t have a transaction between us - people can watch the content if they enjoy it the way it is, or they can find another video. For me it’s fine either way.
I just removed my old stone after 20 years of use to put on a new one and I definitely needed to use a wrench!
Fair enough - I think 20 years of use without removal is way out on the tail of the bell curve of typical users. 😉
I have had a Tornek since 2095 . Diing great . I have always uestioned the angle meaduring the second bevel as it seems the actual cutting bevel should be measured . If the secondary angle is 17 , what is the actual cutting bevel ? Seems it would be much steeper . I have measured with a digitial angle meter and seems the described secondary bevek angle is actual. I was wondering if the actual cutting bevel was refected in setting the tirnek gauge 🤔
Right, works if the stone has not fused to a corroded axle. The cure then is to unscrew the nut, and bang on the end of the axle with a piece of wood between the hammer and axleend……therefore, take the wheel off the axle now and again, clean the axle and give it a little grease, to avoid the fusion of the stone to the axle.
True, and good point… I take for granted that people remove their grindstone for storage, but realise that’s not always possible.
Well, never saw Tormek advice removal of the stone for storage...but seems to be a good idea!
Welches Messer von Zwilling ist das?
Es tut mir leid, es ist ein Kundenmesser und ich habe mir die Details nicht notiert, bevor ich es heute zurückschickte
@@greatedgeltd Sehr schade. Ich habe nämlich auch Zwilling Kochmesser. Aber sie Haben auch mal eine Serie hergestell, die sehr harte Schneiden hatten. 66 HRC. hätte mich interessiert ob es so ein Messer war..
Useful information, Thanks for sharing. For electrical safety, I would also carefully inspect the power cable for damage or wear. I removed the 'restraint grommet' on mine and installed a plug & socket, which I prefer when stowing my Tormek away or transporting it.
Good advice - thank you for sharing. I take for granted the lead checks sometimes but it would have been good to mention.
Good video, certainly has me thinking about my process as well. What is the advantage of this vs just simply using a leather belt on your Ken onion? Seems like the result would be similar? Video update idea: do this same process but use the Ken onion the entire time and finish with a leather belt on the machine and see if there’s any sort of improvement in your BESS numbers?
@@bobekdj thanks very much - I did try going all the way through all the belts including honing with the Ken Onion but never managed to achieve something competitive with Tormek. I am not sure if it’s because the belts are too flexible or the speed is too high, but it just doesn’t seem to be able to match the leather wheel of the T8.. that was part of the background work that led me to the fusion protocol but also I started to realise that if I was anyways going to end up on a leather wheel I could cut out some of the finer grit belts on the WorkSharp. It’s definitely not the way for ultimate sharpness, but I like the ‘BESS:Time’ ratio of this fusion protocol.
@@greatedgeltd that’s the hard part is from a hobbyist there are optimal ways, but those ways are not viable from a business standpoint. You are exactly right on the ratio of time to sharpness. I started with a wicked edge system and was able to get stellar results. I was spending a lot of time and sweat equity for perfect edges, only to have some clients who put the knives back in the dishwasher the next day lol. My 50% sharper was perfect for them I realized because my standards far exceeded their expectations. I took the Ken onion plunge with their mark 2 system (have the flywheel adjusted as close as it can be to mimic a flat ground edge)… I was shocked a the result and how close it was to the wicked edge. I’d say I’m 95% there with a 6-8 minute sharpening time down to 45-60 seconds per knife if they don’t need a lot of repairs. The other thing that helped is to get different belts than the stock ones. I only use 2 belts and a leather strop and the edges are both grippy and easily push cut magazines. I wish I had a BESS tester at my disposal to quantify, but the real world performance has been my metric for a while and never failed me.
@@bobekdjBingo - well said! 🎉
Good information. Thanks!
Thank you, Simon 🙏
Can you describe the belt progression using worksharp naming convention in this video? Not including strop.
Bess media certification methods/criteria ? - How consistent is the Bess media ?
Per the demonstration I gave in this video, BESS media can be very consistent, provided the user is aware of its limitations.
@@greatedgeltd Would you be willing to share your perception or data for the bess testing system accuracy ? In terms of consistency . . . +/- 5% . . . +/- 10% . . . +/- 15% ?
@@danielbottner7700 I don’t have a proper a set of data built up, and certainly not from the past 2-3 years. I’m more of a practical sharpener than a researcher. However all of my experience makes me think 10% is wide enough error brackets. One big caveat though is that BESS measurements are on a single point on an edge, which is not easy to repeatedly test without starting to influence the sharpness of the edge.
Which sharpening wheel would be better for shaping a bowl gouge?
For woodworking tools I’d always recommend the Tormek SG-250 (standard wheel that comes with the T-8). It’s the most versatile and also allows you to work with pressure and/or steeper angles.
I agree. Sharpening on the Tormek is indeed a lengthy and time consuming process. Unless one us using CBN or Diamond wheels. Good idea this fusion protocol.. May try it out.🇨🇦
I also do a fusion method, but it's sort of the opposite of yours. I sharpen on the Tormek (mostly on a 600 grit CBN wheel) and hone on the Ken Onion with leather belts and 1 micron diamond, followed by Tormek PA-70 compound.
Thanks very much - good to know and I’m going to try that out.
I do something similar sometimes in my shop. 400 grit CBN on the Tormek followed by stropping on a leather wheel.
Very helpful. What about the Japanese stone. You didn’t go into detail on that.
Good point - I have an SJ-250 but it never features in my videos. Perhaps something I should focus more on…
another great one!
