Ouch, a heck of a way to make red dye.

Hey, that's a good idea . :-)
I was lucky that all the bleeding took place well away from the spruce and the maple. Going for a tetanus shot and maybe some stitches this morning, it was a deeper cut than I thought. I hope it leaves a scar to make me look tough.

I guess there is an upside to having dull tools.:)

Pix (now out of sequence) of cutting out the sides. First, using a 50" clamp for the long cut. Used a razor knife to cut, easy with veneer. Then, using the gramil to get a nice clean and straight edge, just takes a moment. Next, lining up the four pieces of veneer on that nice clean and straight edge, making sure they line up at the end as well, and taping them together for bandsawing.
A pic of the sides fresh off the bandsaw; I had drawn the profile on the top piece of veneer and then cut all 4 out at the same time. (being careful that the outside veneers were book-matched and oriented correctly in the stack) A little bit of cleanup and they are ready to laminate together in the bending form.

Got this clamp at HF during the 3-day blowout last weekend. Really handy.

Gluing the 2x.045" sides in a vacuum bag. I made up a bag large enough for both sides and a longer clamp, made the bag vacuum-proof, then mixed some epoxy and applied it to the sides with a 1/3 of a roller suitable for epoxy. That West Systems stuff mixes up real easy and is easy to meter with the set of pumps that dispense just the right amount of resin and hardener.
Then taped the 'lams' together, marked the waist, triple-checked that I had the right pieces in the right orientation, then checked again :-), inserted in the bag, pressed into the form, and then pushed the mating form on top, pulling it into contact by means of the springs on either side. Turned it on, see it in the morning.

Next time I will probably use discrete clamps rather than the mating form - it is surprising how strong those thin pieces of wood are, and trying to horse two sides into the bottom form is a bear.

Will pic you tomorrow.

The inner and outer layer of each side is stacked together, already profiled. I made up a template to mark the waist etc.

The newly made bag and clamp. The clamp is just two pieces of hardwood with a matching face that is routed for the dowel. I pull the vinyl around the dowel and clamp the clamp.

Getting ready to apply epoxy to each mating surface. I use a cheap roller and cut it in thirds and toss it when done.

I was a little too busy using both hands to take any pics of taping the sides together to prevent slippage, sliding them in the bag, pressing into the bottom form, pressing into shape with the mating form and clamping and turning on the vacuum pump.

An awkward shot just to show the inside goings-on during the vacuum process.
