I sharpen some of my BS blades but my TS blades go to Dynamic Saw in Buffalo, NY. They are local to me, but I'd still send them there if I lived elsewhere. I've been in their place several times and they were happy to give me a tour and watch their machines run. At a cost of $10 - 15 for a typical TS blade, I don't see the point of trying to do it myself knowing I could never do as well.

Watch the video of the Vollmer grinder in operation. It's worth 3-1/2 minutes of your time. It can grind a lot more than the tooth face.
