Hello,
I offer here an ultralight aerospace-material, ultra-thin aluminium in honey-comb form. Thickness ist 10 mm, diagonal width of each cell is 3-3.5 mm.
I intend to cut it in equal-sided triangle-pieces with side-length 30 cm for lifter-projects, 45 € a piece, shipment not included and only within Europe. Total area available is about 0.8 square-meter. I hope to regain 10 to 12 pieces of the material. To cut this stuff is not an easy task, as it is very sensible in handling and sharp as a razor.
Please respond via pm if you are interested.
Regards
