Sides being laminated in the vacuum bag, in a mold based on Ken Cierp's outline.
Mahogany.
One note - some mahogany loves to split, even at .045". This set did crack on the inside, along the grain - the beauty of lamination is that the process heals that kind of split, whereas with another method the sides would have been toast.

Ok, sides done, top and back joined - one with tape method, one using a shop made jig like Ken shows on his website,
15' braces cut.
Still having trouble with the colors on this camera.
Time to wrap up for the night.

Oh this build will be a fun one to watch.
How are you cutting those braces Dave? Splain it to me.

First I got a chunk of brace stock, then sliced it up with this method:

Then I made one of these:

The bottom of that arching jig is flat, so it can be run against a fence to flatten out the brace, which then, when released will spring into the arc desired.
Not the easiest thing in the world to get that smooth arc cut into the jig. For me, anyway, it took a LOT of tinkering.
