A Tormek question.
Our club has acquired an older model Tormek. It has a 150mm wheel plus the honing set up on the left hand side.
The instruction manual is a hardcover book!
I note the wheel is well out of round, probably by 3mm+.
Is it worth trying to dress the wheel to true it up, and if so how? OR would it be better to simply buy a new wheel??
Many thanks.

If you look at the cost of the Tormek wheel truing paraphernalia you are well on the way to a CBN wheel. When faced with your choice that's what I did, 1200 grit CBN from the US.

I second the CBN suggestion. The wheel is always round, unlike the stone, which needed to be dressed regularly.

Dressing stones isn't rocket science with $500 materials.
How many dozens of blades get resharpened every day?
I suggest that you do both.
Buy a CBN wheel (or 2 ) for long lasting reliability.
Buy a dressing bar or wheel so your club members can learn how to "make do" with'
what they my find outside of the club for years to come.

Thanks fellas!! I have a 1 point diamond wheel dresser that will probably do the job. I will have to get past the clique of knowalls to try this.
As for the CBN wheel, well I do not think the mob will want to spend the money!!
I personally would not let a CBN wheel loose in the club as there are too many hands to ruin it by trying to sharpen or form the wrong materials.

Yep, I occasionally take in my CBN set up to the club and reshape turning chisels, at the members request. My 1 rule is that no one touches the grinder, except me. I decide what is ground.
I now don't even put my bench/firmer/mortice chisels and plane blades on the torment. I find I get better results with Scary sharp/Diamond/Water stones and the Veritas jig.Pat

I am unaware of a Tormek grinder that has a 6" wheel, I thought the smallest was 8", the old T3 or current T4. Identify it, and buy a new wheel, cheaper than a CBN wheel.

Thanks for that George. I will take a closer look next trip to the club.
What are your thoughts on truing the wheel with a 1 point diamond dresser??

I suspect that this Tormek is the smaller version with the 8" wheel, which has worn to 6" over the years. I have the 10" version (2006), and the wheel is 8".
You have to ask yourself whether you plan to grind or sharpen on the Tormek. I used one to grind and have since gone to a 8" half-speed because it is so much faster. If I decided to continue using the Tormek, I most definitely would purchase a CBN wheel for it, which. use on the dry grinder. These are a game changer. For those that have not used them, please do. They will change forever your views on grinding!
There are two wheels available for the Tormek, one is a cheaper version that is based on a plastic centre, and the other is a solid steel or aluminium wheel. Neither are intended to be used wet, only dry. If grinding, I would get a 180 grit wheel. If honing, you can purchase something from 300 - 600 grit these days.

Truing the wheel is very simple, I have a T7. You use the bar, and the Truing Tool is wound across the face of the wheel. Derekcohen (the next post) is accurate about the diameters of the wheel. I have never seen a wheel much smaller than they start.

This machine does not have the truing device and I somehow doubt the foresight of the members to buy one!!
This is why I asked about using my 1 point diamond dresser.

Art, you are in for a world of pain with a single point dresser, unless you can jig it up.
If it was me, I would get a wide diamond wheel dresser.Pat

The truing jig is an accessory for purchase. It does not vome with the machine. The 6" wheel will become 5 1/2" by the time you get it round. That is about 1/2 the original size, if it began life as 8". The Tormek needs a new wheel and a truing jig. By the time you spend on this, you may as well get a CBN wheel, which will last for life and never need maintenance. It is far less messy as it is used dry.

One question I have about CBN on the tormek concerns what happens if the tool bar is not parallel with the CBN wheel?
On a normal wheel if the bar is slightly not square, after using the truing tool - it will be.
What happens if (and I’m sure it’s not a big if) the bar is not parallel with your new CBN wheel?
any thoughts on how you test and correct this?

Well I run the CBN/Tormek set up and never even thought of it after the first installation and check. I think I lined up a 1-2-3 block with the wheel and brought the bar up. No light between them, did me.
