Serrated knife sharpening wheel

[3D Anvil]

Plus I realized afterwards that a serration is not a half-circle, but rather a portion of it, so the diameter can be wider than the pitch.
...snip...

A radius gauge set, like below is the right tool to measure the serrations. Match the curvature of the gauge to any portion of a internal or external radius and read the measurement from the stamped markings. 

Thanks!

So until now I've been getting by on bread knife sharpening by ... not really sharpening, but by using the SchleifJunkies' "leather wheel for serrations" and the edge of a belt to strop serrations.  I was using 1 micron diamond on the wheel and PA-70 on the belt.  Worked okay, but not really satisfactory for a dull knife.

This morning I leveled it up, using 20 micron diamond on the wheel, and I'm pretty happy with the result!  I was sharpening a Mercer bread knife with roughly 1/4" serrations.  Before sharpening, it measured at around 300 BESS.

I did 3-4 passes on the bevel side at the measured edge angle (25°) and then stropped on the edge of a leather belt with PA-70.  That got my BESS reading down to 110-125g, which to me is more than acceptable for a bread knife.

Now, I don't know how it would work with a really dull knife, and it's obviously not going to restore a knife with rounded points, but that's a topic for another day.

Garrett,

I saw what I believe is the same wheel for sharpening serrated wheels on facebook. It is actually a Slipakniven product, not Tormek. I don't know anything about it, although I have had success with the few peoducts I have ordered from ẞlipakniven.com.

Yes, I saw that but he's out of stock. So is Curry's Custom Cutlery Cliff the owner his are out of stock as well. He's out of Hawaii. He has quarter inch, half inch, and 1 inch diamond wheels that are 6 inches in diameter can be run on a Buck tool 1750rpm machine.

What do you mean by the belt?

I recently got a grinder used to sharpen a chainsaw's saw chains.  The grinding wheels used to sharpen the cutters are thin and rounded on the edge.



The two sizes most typically used are 1/8" and 3/16" wide.  They are only 5" in diameter, so I don't think they would work on the Tormek, but possibly they would work on a different style grinder and grind them by hand.

These are available as traditional grindstones (many types), CBN, & diamond.

So to understand more clearly, please, are you using these wheels that are more so meant for chainsaws, and that can be used on let's say a Buck-tool 1750 RPM machine, to sharpen serrated knives?
And if so, naturally, one would have to get two sizes to accommodate the different widths of the scallops. Correct?
Thank you in advance, sir

I have two questions for those of us wanting to sharpen serrated knives with a Tormek.

First question: How many serrated knives do you realistically plan to sharpen, both in number and in frequency? Related to this is how much revenue is projected?

In my own case, I only occasionally sharpen my Henckels bread knife. A wooden dowel wrapped with wet and dry abrasive paper does a very adequate job at low cost. Time is not excessive.

My second question is really a concern for the basic Tormek philosophy of sharpening. Are these six inch CBN wheels going to be used with anticorrosion solution and only remove minimum metal? For me, "the burden of proof" is on the wheels and their use.
