Hello,

I'm having an inconsistent error. It's more than likely to be me and how I set up the machine but 8 thought I'd ask if anyone else has had similar issues.

When grinding the P Facet on a 4 Facet drill then moving onto the S Facet I am finding that once I have set a depth of grind, I am then getting an uneven S Facet. To true up the S Facet with the other I might have to increase or back off the grind depth to get even looking P&S Facets otherwise I'll end up losing the P Facet all together.  Is this normal or am I experiencing a warped drill bit or that the drill clamp isn't holding it true?

I've hopefully attached a picture of what I mean. All Facets have been ground to the same depth.

Any pointers would be greatly appreciated

Hello all,

This is my first post on here. I've owned the Tormek T8 for well over a year now, I bought it originally for touching up HSS lathe cutters with the SB-250 wheel and on the odd occasion sharpening chisels with the SG-250. I treated myself to the SJ-250 a couple of months back and have been very impressed with the results that stone produces, yesterday whilst I was sharpening a set of chisel for a neighbour, I noticed there was cracks appearing running in the rotation direction on the edges of the stone. These are very deep, it's almost like it's de-laminating.  I've tried re truing the wheel to cut out these cracks but they keep reappearing. Any suggestions as to what it might be?

Thank you in advance

Alex
