Yes, I did. Used up the remaining section of 1/2" ply too. I know that Frame 3 and the Seat Sections (4) were originally intended to be cut out of 1/4" ply, but what the hey.
I'm set up for next week's work too. I expect to get my epoxy in the mail sometime in the next few days... so next week will see me working on the mast. I came up with a rig on the table saw to allow me to cut narrow angles on the mast lumber. Two quick cuts will let me splice the 8' and 6' sections. I should have the entire mast blank glued up by Sunday.
Nothing going on after that until the following week's pay check hits.
