Glenn Lucas and another Tormek friend, Nick Agar, will be coming to Anchorage in late January to give turning symposium demonstrations and classes. I've signed up for classes with both. The local turning club brings up two well known turners each year; it is quite the coincidence that two Tormek users were picked. I was so excited with them coming that I figured I needed a new T-8. The club uses Wolverine jigs with high speed grinding wheels, so I plan to provide my Tormeks at the classes. I hope to pick up some tips from both Glenn and Nick. Hopefully, I'll have something to report in early February.

The T-8 Getting Started manual does, indeed, say to raise the trough to the highest position. When I did this, the stone rubbed on the trough. In the Getting Started video, with Alan Holtham, on Tormek's website, he says to only raise the trough three clicks, saving the others for when the stone diameter decreases. You can access the video and download a digital copy of the manual after you register your machine with Tormek.

I'm sure that you know that you can do that grind freehand using the SVD-110 tool rest and following any of the many videos that are out there, so I guess you're asking about using the SVD-186/185. I've never had a gouge with that particular grind, and I don't have a spare gouge to practice on, so I can't help you too much. However, jig setting 5 with the SVD-186/185 will get you the 40 degree angle from horizontal that you need. The numbers on the jig are units of ten degrees from parallel with the jig axis of rotation. You want 40 degrees from perpendicular or 50 degrees from parallel, so jig setting 5. Then it is just a matter of picking the one of an  infinite number of combinations of protrusion and USB setting that give a 40 degree nose angle that results in the grind that you want. Protrusion 55mm and hole B on the TTS-100 comes close, but results in a nose angle of about 45 degrees, instead of the desired 40.

Not much help, I know, but if you find the right combination, please share.

I haven't read any further, but one CBN wheel manufacturer claims that the pure carbon in diamond wheels forms carbides with the other elements in steel, destroying the diamonds. http://www.optigrind.com/page_2538178.html

If you made an appropriate bushing, it seems like the SVD-186/185 would make quick work of sharpening rotary cutters.
