I'm posting this hear as I think turners have a unique view on sharpening tools (because of how often we need to do it). I got my Grizzly clone of the tormek for sharpening things like axes and scissors. The standard wheel that came with it was up to the task just fine and do to the light use really hasn't worn much. But now that I've joined the turning world that's changed. I don't need to do anything in a hurry but I wouldn't mind not wearing down the stone wheel I got now to the point where it's useless (The need could arise where swapping back to it for a specific item could come up). So I don't see a lot of point waiting too long before upgrading.
I thought Tormek would of had their diamond wheels out now and there would be plenty of reviews but that doesn't seam to be the case. The speakers on my laptop suck so I can watch videos but can't hear them so haven't watched a lot of them to see if there's a good comparison. I have learned some, like diamond will not work on high speed grinders and CBN on soft metal but was hoping others could chime in.
My use will mainly be turning tools. I'm not opposed to getting another grinder if it's the best solution but noise and dust are an issue since I usually turn at night in the basement after the wife has gone to bed. I also have several tormek jigs (like the one for doing gouges) so I'm kind of invested in using what I have. However I see tormek does have an adapter to use their jigs on a standard grinder.
So what are people's opinions of a diamond wheel over a CBN? A good quality one of either is going to cost around $300. Can I get away with just one grit and use my regular 6" grinder for reshaping tools or should I just plan on getting at least a course and a fine grit? I don't want to switch wheels but that's based on a stone wheel. With either the CBN and diamond they should just be swap and go without the need to true the stone up so I'm guess that I'm thinking I have a flawed old school line of thought with newer technology. Will both last a very long time or will one have a longer life than the other? I'm asking in part because I think there's plenty of people who are going to be asking questions like this and hopefully others besides me can get answers.
