I acquired a Tormek just a few days ago and this vid steered me away from several bad habits I would have picked up from other YTers. thx.

Very true. I remember when I was switching from bench stone sharpening to Tormek, I had a hard time to change my sharpening habits.

According to Tormek, the grading stone can also be used on the Japanese SJ wheel, but we caution against if you like your SJ. Tormek had developed their grading stone for the aluminium oxide SG wheel long before they added the SB and SJ wheels. It can grade finer the black SB wheel, but not to the #1000 as the SG - only to about #600; however it cannot restore the SB wheel to its original coarse grit, and if you keep trying you will glaze your grading stone on the SB wheel to unusable.

This is because the Tormek knife jig is not self-centering - when the edge apex is not at the center of the clamp, you get one bevel higher than the other. Our solution is explained on our website here: knifegrinders.com.au/05Equipment_jigs.htm

@@knifegrindersaustralia5158 can I purchase your burring book direct from you? Try not to use Amazon as much as possible. Thanks.

Sure, on our website in PDF, and it is cheaper than from Amazon. You can read and save the PDF book on your Windows PC, Mac, iPhone/iPad and Android smartphone/tablet. knifegrinders.com.au/11Shop.htm

@@knifegrindersaustralia5158 thanks, I was actually looking for the hardcopy. Should have been more specific

No hardcopy at present, sorry. But now that I honestly think that the 5th edition is final, I will let half a year for feedback and will have it printed in Australia then. Though, the overseas transportation costs added to the printing costs will make it less affordable for the overseas readers.

Please see explanation and solution on our website knifegrinders.com.au/05Equipment_jigs.htm

@@knifegrindersaustralia5158 thank you!

Does part KJ-45 fix this problem? (Centering knife jig)

Glad it helps

Wrong position of the operator - the operator should be behind the Universal Support, not in front of it.

@@knifegrindersaustralia5158 Ah, makes sense. That's how the Tormek guys do it in their videos as well. Thanks for clarifying.

it is difficult to get mirror polish with diamonds - there are SEM micrographs in my book showing that aluminium oxide is better for the mirror polish

@@knifegrindersaustralia5158 Everybody's gangsta until their mirror polished knives blind them on a sunny day! It's useless for every knife, excluding display pieces

@@knifegrindersaustralia5158 I'm confused why diamond paste is the way to go for honing rather than the AO that they suggest. Is it so that the diamond paste "tears" everything out evenly (iron matrix and carbides) rather than just the iron matrix causing "carbide tearout" that the AO paste produces?

@@cosmicsloth246 Diamond paste should be used for high vanadium/cobalt/tungsten steels, not only because aluminium oxide etc common abrasives worsen their edge retention, but also because common abrasives cannot sharpen the edge of carbides, they only draw steel matrix over the carbides into a short-lived edge that dulls quickly.

You are doing nothing wrong, simply the blade is too narrow. Try clamping higher at the very spine. If still the same, you can thin the clamps of the knife jig on a common grinder to get some clearance over the wheel, as shown on this photo knifegrinders.com.au/photos/Knife_Jig_Thinned.JPG

@@knifegrindersaustralia5158 Sorry, I still don't get it! The reason for the tape was suppose to prevent scratching the blade? It would now appear that the tape has another function totally? Your explanation is clear and concise. I just haven't used a Tormek. I polish Calcite Optical Prisms.

There is a business selling adhesive pads for the knife jigs, but if used with the Tormek knife jig, they move the apex of the blade off the centre. If the blade apex is off the centre, you will grind bevels of uneven height. We need the blade clamped in the knife jig to be centered in the jig, to have the blade apex in the central plane of the jig. If you put pads on the clamps, the blade apex will go off the centre of the jig. It is so because the Tormek knife jig is not as simple as it looks - it clamps asymmetrically, you can read more about this on our website here: knifegrinders.com.au/05Equipment_jigs.htm

The 63*150mm diamond plate will work as well - any plate wider than the wheel will. These plates last, but wear down with time, so I would use the cheapest I can find, and for sure not the DMT :)

@@knifegrindersaustralia5158 Yeah, they are nicely cheap btw, got two for about 8 euro's from China. :)

Another question: Did you try the diamond plates with the SB-250 silicon carbide stone? Might get a similair result as the SG-250 normal stone... Might be interesting for some :)
