Thread: Broken wet wheel

So did you give up?

Or did you invest in making a Derek Cohen 10c sharpening system?

You wouldn't have a little thing like that stand in the way, would you?

Give up? No. I used the other Scangrinder - I have a spare - from Derek as coincidence would have it

How did it break?

Did something fall on it or was it just the climatic conditions?

Hi Groggy,

I thought it ain't broke without pictures ??

What Cliff said. How come you reckon ?? Bit of a shock to discover!

Cheers

I have a picture but can't put it up at the moment because I am having a technical problem with my account.

I think the crack came from it drying out but I must confess I don't really know for sure. It certainly has not been knocked or dropped .

EDIT: tech problem fixed - here it is

Given the slow rpm of the scangrind, could you still use it. At worst it will just fall apart, not go flying around the room like a bench grinder.

Greg, Ive got one of them Tormek things with the same sized wheel and havent had any probs over 6 years with it.

Makes me wonder from your pic, there isnt a timber insert in the centre of the wheel that has expanded to make it crack?

I'll certainly give it a go. This one is set up for large blades (jointer & thicknesser) and I'll have to sharpen them soon so I'll let you know.

(Had to go and check) No Al, it is a dark plastic.

Good, got to eliminate the obvious first as it doesnt seem possible to crack a wheel like that without some sort of impact or swelling.

Next, quiz the family.

My daughter admitted guilt but I think it was just the thumbscrews talking...


Going to be a mystery I think Al, an expensive mystery.

Greg

Sorry to hear of the break. Good thing you have a spare!

Before either discarding the wheel or replacing it, try epoxying it back together. This works for waterstones...

Epoxy eh? Hmmm.

Won't that affect its expansion rate?

As a matter of interest, when you had the Scangrind, did you keep the wheel wet or dry it out after use?

I only usedit a few times. When I trued it, however, it was always dry. That way it is possible to see what the surface is doing.
