In the past we've had friendly debates about the best system for sharpening turning tools. (I've still got some scars from the last debate.) I'm in the minority that prefers using a slow speed, water cooled, grinder, like the Tormek. Tormek's patents expired a while ago and there are now a handful of clones available. Recently, a member of a UK woodworkers forum bought and returned two of the newer clones before buying and keeping a Tormek T7. He wrote up his experience in the form of a review that you might find interesting.
Here's how to find the review (I don't want to post a link for fear of running a foul of the terms of use): Go to ukworkshop.co.uk and click on the "Fourms" link at the top of the page. From there, use the search function to search for "Tormek" in the "Buying Advice/Tool Review" forum. The review should be one of the first in the list that comes up under the title of "ukworkshop.co.uk/forums/viewtopic.php?t=23560&start=0&postdays=0&postorder =asc&highlight=tormek++review"]Tormek T-7 review (versus Scheppach versions)".
Hope you find it interesting. Please note, in the discussion that follows the review two points are made that I disagree with. The first is that someone says you shouldn't flatten the back of a chisel on the side of the grinding wheel. That's probably an unsafe practice with a high speed grinder, but I don't think it's a problem with the Tormek's wheel that's spinning at about 100 rpm. The other point I disagree with is the poster who said you can't hone and edge on a leather wheel (you'll round over the sharpened edge). Again, my leather wheel produces outstanding results -- particularly if I don't hone freehand! With the new turning tool jigs, setting up the proper bevel angle (on the grinding wheel or the leather honing wheel) only takes 5 - 10 seconds. So there's no need to take my bowl gouge out of the jig for honing.
All the standard disclaimers apply: I've no financial interest in Tormek, just a satisfied customer, etc. I could never get my tools as consistently sharp with a consistent shape and bevel as I can with my Tormek. YMMV.
