Hello

[Craig Regan]

The purfling comes in at a heavy 3/16", or 1.12" or 7/64". The black is .30", and the cherry is .50" (My dial caliper measures in .00"). Its looks wide on the spruce side, but blends in nicely on the cherry back! It looks like two separate black stripes when inlayed in to the cherry wood.

Channel 2 mm deep, edge 6 mm thick, after trimming the edge to 5mm, there should be 3-4 mm of material under the purfling. How deep should I go? Does the depth create the so called hinge effect?

[Arnold Schnitzer]

5mm is thin for the edge. 7 is more common.

[Craig Regan]

The hollowed out scoop is at 5 mm, and the rolled over outer edge is 8 mm.
Chandlers plans call for 4.5 plate thickness next to the ribs, and 6 mm plate thickness next to the ribs at the f holes. For now, I'll try to keep it on the heavy side.

Check again. .50"/.500" = 1/2". Do you mean .050" and .030"? Missing a zer0?

.050" is like a G string or so in diameter and .030" is like a high C string.

I think I'll switch to the metric language.

Black veneer .70 mm, Cherry 1.24 mm, total thickness 2.64 mm.

You were just short that extra zero I mentioned. You had it listed at 10x the size without it.

.70mm = .0275", 1.24mm = .0488 , total = .100"/2.64mm

In dividing for MMs, use 25.4 instead 2.54 or you get 10x like with the Caliper misread.

Glued (and clamped) the last of the purfling in the top.
My son thinks it looks really cool.

[Craig Regan]

Graduating the top.
I made a special table/cradle to hold the top plate.
Today, I will start to carve out the underside of the top deck.

[Arnold Schnitzer]

I see you have posted a graduation drawing. That thick ridge down the center is not traditional,. It is typical to work in more of an oval manner out from the thickest center zone. I believe the drawing is from the Chandler book, which contains some good basic info but is short on specifics. You will want to cut your f-holes while the top is still a bit heavy. Otherwise you will be cursing everytime a little tear-out episode happens on the inside.
