Ok just a small update on the build
I got the printed forms glued up on some 12 mm MDF these were cut out and sanded up

these also had a rectangular hole cut in then along the centre line and with the lower edge on the water line
these have been threaded onto a 75 x 50 x 2 mm steel section that makes up the strong back

I have to make up some 238 mm spacers ( 16 of them ) and 1 adjustable to pack the forms out at the right spacings
I've picked up a small band saw to cut my strips up on so a couple of tables and a long fence to hold the planks true will be on the agenda
same as I have to order some Paulownia ( wood )
so progress is being made
