I have had a T7 for about a year now and frankly I am kind of frustrated and disappointed with it. I am hopeful that it is just me and not the machine. When I use the T7 to sharpen anything it seems like the wheel does not stay flat across it's surface for any length of time. I use the truing tool to get it flat across the face and then with in several swipes with a knife or jointer blade the corners are rounded off. This as you can imagine doesn't bode well for getting nice edges on anything. So what the heck am I doing wrong? I have watched the videos so many times I can almost recite them by memory. It would seem to me that the wheel should stay relatively flat across it's face for longer than a few 5-10 swipes across it. Also is it normal for the wheel to load up with material while sharpening? What I mean is there seems to be a significant amount of metal that gets imbedded into the middle part of the wheel mostly and I have to use the stone grader to attempt to remove that material so that I have clean stone facing the tool i am sharpening. My last question is about the OEm stone, is it capable of sharpening jointer knives adequately in a reasonable amount of time or should I be looking at getting the black stone to do the jointer knives? It seemed to take a very long time to sharpen 4" jointer knives on the T7 and when I was done I ended up with somewhat sharp knives but they were not square/flat across their length. If I put them on a flat cast iron table I could see light underneath the knives which is not good for getting a nice flat cut across a piece of stock obviously. I really want to be able to use this machine i paid a lot of money for but it is really causing me to feel beaten and broken. I have really screwed up some of our kitchen knives sharpening them as I kept sharpening them probably too long and ended up causing the blade to not be flat any longer or completely changing the blade profile altogether due to excessive grinding. I need help here please.
