Well, 3 weeks later and I'm almost (or only depending on my mood) 3/8 of the way through stripping.  Slow going when only work about an hour a day...  Started skipping the ribs that are cracked out of shape.  May try to save ones that are cracked - perhaps try edge gluing with West Systems and a hair drier?

Last weekend Dave and I went to Parkerville lumber in Manchester.  Cool store - lots of different woods available.  Picked up 4 5/4x6x6' northern white cedar boards.  Dave took one to the Cape to make a few trial ribs.  The ribs are a bit more complex than I thought.  In addition to the width varying from 9/4" to 6/4", the thickness appears to vary from 3/8" on the floor to 5/16" at the gunnels.  Sides are tapered on both sides from full measured width.

Snapped a couple of pics I will post next time I download from the camera.

Got a reply from OldTown to my early e-mail.  They sent another copy of the build sheet, and offered some encouragement and to be a source of materials.  Nice reply.

Costs keep accumulating - another $60 for stripping supplies and $140 for rib stock last weekend.

I'll send Bob and Nancy an update on where I am with a Christmas card...
