Re: what kind of grinder to buy *LINK*

>Tim, I have three grinders, a cheap 6" high speed, the Delta 8" low speed and a Tormek. The 6" is good for grinding bolts, odd pieces of steel and not much else, I would never use it on a turning tool. For a dry grinder, you can't beat the 8" low speed Delta. It weighs 100lbs and has no vibrartion. A heavy grinder is much like a heavy lathe, the less vibration the better the cut or in this case grind. I replaced the gray wheel with 100 grit white wheel (only because I couldn't find a 120 grit white). I use this for reshaping (using the 60 white that came with it), scrapers (100 grit) and for sharpening my Ellsworth gouge (have my Ellsoworth jig setup on it). For all else I use my Tormek (220/1000 grit).
You can look at the articles section for Lyn's article on sharpening. One of the observations made the comparison between the Tormek and dry ground tools, was the Tormek edge lasted longer and cut better. I have found the same in my usage. Which ever way you go, I would not scrimp on a cheap light weight grinder if you go the dry route. Either the heavy Delta ($169) or Baldor ($300+). If you do other woodworking and have a jointer and/or planer you are cheaper buying the whole Tormek package and not just the woodturner package if you go that route, its a lot cheaper in the long run - don't ask how I know :-) ....
As far as the time it takes to set up the Tormek, you can make some "setup" jigs or measuring devies that make it as quick to setup as a dry grinder. I also alternate between the grinder and the leather wheel to hone the edge. I freehand the leather wheel which only takes a few seconds and brings the edge back. But as with all things, you will get opinions extoling the virtues of one system and degrading the other. No one goes out and marries an ugly woman/man/significantother (at least sober), just ask them. And no one buys the wrong sharpening system. Same logic, wouldn't buy it if it wasn't the best. If you can try both and see which one fits your needs the best and good luck in your quest.
