In an effort to stiffen my larger lower bed (~450mm^2), I’m looking at making a aluminum honeycomb sandwich. At my favorite store (Amazon), I have choices from 1/4" to 1" thickness of 1/4" cell AL honeycomb. Does anyone have experience working with this material? I’m wondering about the stiffness. Obviously putting it between 1/4" MDF sheets will do wonders over a just a MDF sheet, but I’d also like to switch to 1/8" MDF (or plywood) when making the sandwich to reduce weight a bit. Seems like the 1/4" AL may be too thin, but that’s not based on experience.
Thanks for any thought, speculations, etc.
