General Tormek Questions / Re: Tormek Grinding wheel chea...
Last post by John Hancock Sr - November 18, 2024, 12:26:49 AMThere are a number of Tormek knock offs such as Wen. Any of them should be suitable. You may need to pack the bore which is 1/2" = 12.8mm as opposed to 12mm for the Tormek. A layer of blue tape may suffice.

General Tormek Questions / Re: PM-V11 steel grinding
Last post by John Hancock Sr - November 18, 2024, 12:22:28 AMYour problem is that PM-V11 is harder than you Aluminium Oxide or corundum wheels. I have some PM-V11 and I sharpen them with Diamond wheels. Not sure why you have issues with diamond bench stones with PM-V11 - they should be fine. They will obviously take longer than lower hardness carbon steels but that is to be expected.
Your options are Silicon Carbide or the black stone, Diamond and CBN all of which are harder than PM-V11 and thus suitable for sharpening them.
The wheels you linked to is corundum, or Aluminium Oxide and thus too soft for PM-V11 - pretty much the same as the Tormek SG wheels.

Knife Sharpening / Re: checking deburring
Last post by John Hancock Sr - November 17, 2024, 10:37:40 PMUsing plastic in the fingers is an excellent method since the tips of our fingers have a lot of nerve endings and are this sensitive to any movement or irregularities. The trick is light pressure. the more gently we hold it the more sensitive that method would be. Holding it too tight will swamp the nerve impulses and dampen any vibration. It is like looking for roughness, very gentle is the trick.

General Tormek Questions / Re: Tormek Grinding wheel chea...
Last post by Ken S - November 17, 2024, 04:17:29 PMWe might be able to give better answers if you gave us more information. Are you sharpening junky knives as a business or for yourself? How many junky knives are involved?
If you are charging for your sharpening and are worried about the cost of a SG-200, you are not charging enough. Whether you are sharpening for others or for yourself, youwould do everyone a favor to switch to fewer reasonably priced knives of better quality. Victorinox fibrox knives are quite reasonably priced and are of good quality. A chef knife and a smaller knife should cover the needs of a typical home kitchen.
The useful life of any grinding wheel can be extended by frequent honing on the leather wheel. A friend who was a longtime Tormek demonstrator told me that grinding wheels last longer after the learning curve of the first wheel. He also told me that he hones more often than he sharpens.

Did you know about these?
Thank you

Knife Sharpening / Re: checking deburring
Last post by Drilon - November 16, 2024, 04:58:37 PMHello Ken,
my favourite method of checking for burrs is the "Q-tip test". Hold the knife with the blade horizontal and the side where the burr is expected to be facing up. Then let a Q-tip glide along the edge. If there is a burr, the Q-tip will be held by the burr (see photo). If there is no burr, the Q-tip will drop. This is also useful for checking for burrs after honing.
Regards, Drilon

General Tormek Questions / Re: PM-V11 steel grinding
Last post by RickKrung - November 16, 2024, 03:05:22 PMCouple options, one cheap, the other spendy.
1) traditional grinding wheel, such as 64 grit Norton 3X, mounted on the Tormek. Takes some custom fitting to mate the 1" arbor hole to the 12mm Tormek shaft. Can be a simple as drilling out some PVC pipe to go with the plastic bushings that come with the wheel and some 12mm fender washers to fill the space. Or, if you have the ability to machine your own, make the bushing and flange washers (or have them made at a machine shop). Do a search on the forum for "Norton" and you'll turn up a number or threads on this. I machined my own bushing and flange washers. AFAIK, Norton only come in 8" dia., which work, but I came into a 10" dia., no-name wheel that works much like the 250mm wheels.
2) Coarse CBN wheels, run in water on the T8. Third party vendors supply them, some can be run in water, at least one states the warranty will be voided if run in water. I've been running a 180 grit CBN, from the "no water" vendor for years without any problems. I use the Tormek ACC solution and am careful to dry the wheel after use.
Another option is to get a variable speed belt grinder and run it as slow as it will go for roughing and then take them to the Tormek.
Way back, before doing all of the above, I tried the SB grinding wheel. Does work better but tends to glaze up quickly.
It also may help to get some coarse diamond plates to remove the glazing, short of retruing the wheels, for both the standard and SB wheels. Search "diamond plate" and you should find discussion of this. Knife Grinders may have been the originator of the diamond plate technique.
