Woodborg a fingernail grind is just that, looks like a fingernail shape
and is typical used on spindle gouges, but can also be made on a bowl
gouge, however the irish grind was devised for the problem we have
turning the bottom of deeper bowls, where the gouge's bevel on the
straight across grind or fingernail shape can not and does not contact
the wood anymore, and turners than used scrapers to take that wood out,
making for some real surface problems a lot of times.
The irish grind does make it much easier to do this by having the wings
of the deep bowl gouge ground back and onto the side of the gouge, and
makes it possible to cut the wood all the way from the side down to the
very center.
Using the jig does not make the profile though, if you grind on the
sides you'll end up with a point, you will have to first get the
profile right, and then it is much easier to keep that profile with the
jig, also less material to grind away so it is much quicker.

Have fun and take care

Have just looked through all the instructions and video. You make it
look very easy to the point that i will have a go this weekend. Just
need to buy some dowel.
I brought a very cheap wet grinder with a normal grinding wheel
attached. Up to now i have been free handing on the wet grinder, my
spindle and bowl gouges tend to be sharpen to a point, its about time i
had some conformity of shape which hopefully will cut down on sand paper
usage
with thanks and keep up the great work
ps whats the difference between a finger nail grind and a irish grind
please
