Ive only owned my Tormek T-4 for a few months now, but Im having issues with gouges in the stone. Let's start by also saying I keep my knives sharp so i only have to polish a little on my SJ-200 stone and strop. I bought a set of digital calipers and using an angle calculator to find the angle of my edges. After setting the correct angle with the WM-200 angle guide, I have been sharpening against the grain of the wheel. I keep the edge flat when drawing across the stone but three times now for whatever reason, I the blade has caught the stone and gouged a chip in the wheel. I have to flatten the wheel until the chip has gone away. At $332 I cant afford to wreck the stone like that. To combat this I have been free hand sharpening with the grain the wheel instead of against and eyeballing the angle. I have been getting razor sharp results. So a couple questions I have are 1- Any ideas what am I doing wrong to gouge the stone? 2- Can you use the knife jig when sharpening with the grain or is that just for wood tools? Id love any advice anyone can give. Thanks.
