I've recently re-ignited my turning hobby and my motley collection of weirdly ground, poorly sharpened turning tools (along with some that aren't so bad). Since those days, I've added both a Tormek T-7 with a pretty new SG-250 wheel and a T-8 with a DF-250 600 grit diamond wheel. Nearly all the tools need to be re-ground properly but I'm finding it's taking literally HOURS to do.
I spent 4 hours yesterday on a 1" oval skew starting on the SG-250 surfaced to 300 grit, freshly dressed. Initially, the bevel formed nicely, but as I continued, the progress got slower and slower until I eventually gave up and left a 1 mm crescent of the original bevel. I was literally using a dissecting microscope to see if I was making progress- I was, but INCREDIBLY slowly. I resurfaced the stone a few times thinking maybe some fresh sharp peaks would help and maybe it did, a little.
Other sources (reddit, I know, reddit...) suggest that slow speed water cooled grinding isn't necessarily an effective way to get the initial grind?
Am I missing an important technique here? Thank you for your input!
