    sharpening turning gouges

    I just got the Woodcraft slow speed grinder. It came with a 60 grit wheel on one side. The other side was a 120 grit that I replaced with a diamond wheel. Christmas present to self. I have it set up with the Wolverine jig.

    I ordered a couple of spindle gouges from Doug Thompson. I love his tools! They just came in the mail. WooHoo! One has no grind on it at all. Certainly the 60 grit wheel will remedy that.

    Question. Can I go from the 60 grit wheel to the diamond wheel efficiently, or do I need to put the 120 grit wheel back on? The diamond wheel is rated at 120 grit, but it sure feels smoother than that to my fingers. Since Doug's tools are not the ordinary HSS, does anyone have some experience here?

    Well I have seen with my own eyes a well known turner here sharpen bowl gouges with just one wheel. Turns the end all blue and every thing.
    He also didn't wast time with a slow speed
    I should add that the look on my class mates faces was priceless when he turned around with the gouge all sharp and blue.
    It could be worse You could be on fire.

    Grit to use will get ten opinions from six people.
    Some use a 46. I was originally told by a professional turner to use only 80.
    Recently, I got the same grinder you have and started using the 120 and have no intention of using anything else.
    With your set up, I would put the 120 back on and replace the 60 with the diamond.
    You need only one to sharpen. If the diamond is very fine, maybe you can hone with it. Do what works best for you.

    I'm pretty sure going from the 60 grit stone wheel to the 120 grit diamond wheel will work just fine. I'd say try it and see if you like the results. As Frank said, there are almost more sharpening opinions than there are turners, and any of them are correct if they work for you. For me, I do my scrapers and hollowing tool bits on an 80 grit wheel and gouges and skews on the Tormek. Prior to the Tormek I liked using the 120 grit stone wheel for my gouges

    Doug's tools will still sharpen about the same as any other HSS tools. They'll just wear stone wheels down a bit more than softer metals.

    I personally like using only a 120-grit wheel, which acts like a finer wheel on a high-speed grinder than on a low-speed grinder. I wouldn't use any lower grit wheel, at any speed, for any purpose other than rough shaping.

    One word of caution... never ever use that diamond wheel at anything like high speed. Curious thing about diamond - it withstands temperatures & thermal shock beautifully, but if it comes into contact with iron (any kind of steel) at high temperatures (including dry-grinding temperatures), the diamond erodes very quickly as it dissolves (true story!) in the iron. The resulting steel has an increased carbon (in the form of ferric carbide) content.

    Diamond wheels work very, very well for grinding carbide, and manual diamond hones work terrific on steel, but diamond grinding wheels aren't the best thing you can use for grinding steel; good aluminum-oxide wheels work best for that.

    I use the 80 to regrind a profile and for the long Wolverine extension for the roughing gouge and skew. I use the 120 with the Vari-Grind 2 for the spindle and bowl gouges, and the platform on the 120 for the scraper and parting tools. I try to leave the jigs in place so I don’t have to readjust the angle. I’m lazy.

    Carol,
    First of all thank you, the 60 grit is fine to shape the 1/4 inch spindle gouge followed by the 120 grit... when roughing the spindle gouge place it in the jig then roll it back and forth in a large arc.

    Reed Gray uses a diamond wheel all the time with good luck but I never used one to grind lathe tools. The secret to grinding is to let the wheel do the work very little pressure is needed to remove steel. Very fine wheels need to be dressed a bit more often than the course grits.
