Damo, you're more than welcome to bring any new tools round for their first grind to establish the preferred profile. To be honest it's a bit of a nightmare to start with so some assistance is welcome. I spent many hours wading through information to determine what kind of grind might suit my style and in the end pretty much followed the established norms. The problem is knowing what the established "norms" are because though everybody talks about a "fingernail" ground gouge, there isn't really a standard. The only standard for gouges I'm aware of is the regular factory grind of a 45 degree bevel and a straight across grind giving the same profile as a roughing gouge. That would be the same as the Crown deep fluted gouge that Stiggy brought to which I swept back the wings. Now I swept them back to what I consider to be a useful and maintainable amount given Stiggy's stage. I didn't go too far as it would make it more difficult for him to repeat the grind once he's back home. But that's my opinion, not a standard. Of course most of the tool manufacturers also sell a fingernail ground gouge and in particular Robert Sorby's fingernail factory grind can be replicated exactly using the pro edge. But again, not a standard, just Sorby's opinion on the "average".
So one cant get away from the necessity to tackle the thinking through and learning of how to manage fingernail grinding so you can get a decent edge which you can repeat every time you need to freshen it, which as you saw with me yesterday is frequently to be both safe and to avoid a lot of sanding. A man called Bill who is infinitely wiser than I once told me don't do a grind until you know why you're doing it! That sounds silly but when you start to delve into the "dark side" and somebody shows you a celtic or Ellsworth grind, you will have a rush of "gouge envy" and start removing metal at an alarming rate. So that's the best advice I can give, know why you're after a particular grind before you start.
So what I'm saying is by all means nip over whenever you're passing with whatever tools you need attention and we can get them set up. I run my business from home so am around here most of the time.
