I have been down to Marlow 3 times recently and will post some pics next week I hope. Meanwhile the 10mm thick foamboard sheets arrived and I have started making wet-panel boxes again. I needed a 10x14 carrier for the Venice trip although I may not take boards as big as that. Also, I noted that BA would allow me two cabin bags, one of which would be for a laptop or similar. I duly massacred an old laptop bag, reducing its weight to 1 Kg and made a box with the new foamboard, balsa wood spacers, sewing pins, glue and gaffer tape. With 10 boards (4 of 14x10 and 6 of 12x10) in it the whole assembly weighs 3Kg.
Here is the box inside the laptop bag:
In this one you can see the slots for 10 panels, back to back in pairs:
All I have to do now is get it past those pesky bag inspectors at the airport.
On to the next box!
