Thought I'd provide a bit of a limited update on this topic. I decided to order the new Grizzly 10 inch machine. I also ordered the Tormek woodturners jig accessory pack. For what it might be worth, the Grizzly machine seems very well made and very sturdy. It now comes with a jig that can be used for chisels as mentioned by PBarter. All of the Tormek jigs fit without any problem, however as Bob mentioned above, looks like the support bars for the Jet and Tormek are a different size. The diameter of the support rod is the same for all, but the mounting brackets are different widths for the Grizzly. Seems to work very well, but at theis point the only sharpening that I got done was with some scrapers. The stone left a flawless finish on all of the scrapers I cleaned up. Scrapers may well be one of the easiest things we put on a grinder and since I have all of mine set with the same degree of bevel, it only took a few minutes to re-surface about a half dozen of various sizes and shapes. But they are sharp, and with the jig, the bevel was repeatable and quick.
Also, as Bob mentioned, the threaded stud used to attach the leather honing wheel is a different size than the add-on honing wheels that come with the Tormek jig set. The Grizzly threads are 8mm and the Tormek (and presumably Jet) are 12mm. Need to find a source for a threaded coupler that is female 8mm thread on one end and female 12mm thread on the other. I know we have some machinist types here on the IAP and I'd be interested in talking with one of them that might have some idea as to where I could procur such a coupler. My first thoughts were a simple version of two 8mm nuts threaded on to a bolt and welded together, then do the same thing with two 12 mm nuts and then weld those together in line. But it would have to be pretty accurate so that it didn't wobble like crazy. Guess it could be done easy enough with a long enough 12mm bolt that was ground down to fit inside the 8mm nuts to keep it lined up for welding. I think I have the concept, but don't have the tools (welder, etc) to do metal work. But for those of you that do, I'd like to talk.
I'm not one to spend money foolishly (except for this addiction

) but with the cost of the Grizzly machine added to the cost of the Tormek woodturners jig set, I figured that I've spent under $400.00 for a system that will give me scary sharp turning tools, plus the benefit of sharper kitchen knives, etc. I have no horse in the Tormek or Jet race, but the extra $230 to $150 I saved will buy a lot of wood. If I can answer any questions about this grinder or help anyone else contemplating this sort of configuration, let me know.
