Storms Rage and the Marine Plywood Arrives

The Jet Stream has dipped and is sending storm after storm across the Atlantic to pound against the cliffs outside. A good time to be building boats rather than sailing them.

I've made all the moulds (molds) now but I couldn't mount them on the building jig as I needed the floor space to cut up the large sheets. Below is a sheet laid horizontally ready for marking.

I select the appropriate section from the plan of moulds

and mark it out on the sterling board.

 I use nails to mark out full size the shape to be cut 

then run a batten around the nails, and pencil around the batten.

 Finally, I remove the batten and nails and cut around the pencil line with a jig-saw.

The marine plywood arrived from my local supplier today, the thickest sheet, 8' x 4' x 3/4  (2500 x 1250 x 18), cost £42 (US$ 64), it was going to cost £126 a sheet from the place in Bristol, great saving there.

Altogether the plywood sheets cost £294 including 20% tax.

Therefore the cost to date is
