Hello,
I bought the T7 a few months ago, and use it primarily to "rough out" stainless cutlery for my sharpening business. This has helped cut down the time, (and effort!) spent on that part of sharpening so I can finish on benchstones, my "selling point". The problem is that I can barely do between 7 and 10 knives before having to re-dress the stone, as it gets out of round extremely quickly, it seems to me. When I pass the dressing tool, the amount of out of round I can see sighting along the surface always seems enormous, and it causes a lot of vibration as i near the outside of the stone. I've checked the axle, and it seems true, but the stone wobbles about 2 mm at the outside edge, (already down to 215 mm diameter!)on the shaft when not screwed on. A tech from Tormek indicated that this was normal due to grinding stainless steel, but at this rate I'll need a new stone for each 2 or 3 hundred knives. Does anybody have any ideas about a solution? (I've considered the black stone, but this has got me a bit worried.
