First Hollow Grind

Tried my first hollow grind today and well, it was interesting. Anyway it's almost ready to have scales mounted. I'm thinking curly maple with a waxed finish. Any other suggestions?
 
Looks good, nice grind line. Curly maple should look good, is this stabilized? If so, a wax finish should be just fine..... or, you might like to try Tru-Oil finish.

I have some 30 year old kiln dried curly hard maple. Would I need to stabilize it?
 
Well sort of. I used the tool rest to steady my hands. It's a totally different than flat grinding, in my opinion. My wheel is 8", I think a larger wheel would be better for doing high hollow grinds. With all that said, I enjoyed making the grind. I've read that while hollow grinds make good slicers, the flat grind is still more popular for an all around blade shape.
 
Paul, the 8" wheel is just fine for learning hollow grinds - the curve made by the wheel is smaller, and a tad easier to hold the blade in place - or it is for me anyway. I think using a rest for your hands still qualifies as "free hand" grinding. You didn't use a jig, you used your hands {g}

That curly maple will work just fine, but might need a finish other than just polishing and wax. I'll let other folks chime in on this, if sanding to a really fine grit (1500 to 2000?) will be sufficient for a nice finish, or if it will need something in addition, tru-oil, etc.

I did a little research and you are correct. I need to put a touch of dye in to pop the end grain and sand to a high grit and then use a finish. I'm thinking a water base, but may go with oil.
