Celtic Mandolin #9: Inner Surface


This is part 9 in a 13 part series: Celtic Mandolin

Well, the last exercise on the outer surface was a mistake. I should have left well enough alone. There's way too much material removed by drilling and hollowing out the recurve. Oh well, that's why this is a mock-up.

On to the inner surface. I set the quill-stop to 5-1/2mm from a center pin and drilled a bunch of holes. I clamped the part to a cut out piece of plywood fixed the whole affair to the bench. Then I scraped out the waste material using an inshave and my round bottom plane. I had to use a spoon gouge to get to the bottom in the middle area, then sanded with 60 grit paper. This went a lot faster than I expected. Pretty happy with the way it turned out.
There's a few holes up near the neck that don't need to be there and I'll leave them out when I make the actual soundboard out of spruce.
Next step is to map out and. refine the thickness.
interesting process rhoots.

working with my hands is a joy,it gives me a sense of fulfillment,somthing so many seek and so few find.-SAM MALOOF.
