Mounting electronics

[dtengineering]

Why not use thin baltic birch plywood? Wood is about 1/3 the density of aluminum, so you can replace 1/8" aluminum with 1/4" ply and still save weight. If you have to drill an extra mounting hole in the wood, you don't have to worry about conductive shavings getting in your electronics, and you end up with a non-conductive platform, in the event anything comes loose.

As for mounting the electronics, I prefer to use #8-32 nylon machine screws and nuts. We saved over one pound by switching from metal to nylon, and gained the added benefit of having non-conductive connectors.

I'd stay away from the double-sided tape... it works... but any tape sticky enough to actually hold your electronics is likely to be a pain to take apart, or at least leave a mess of tape to clean up when you are done.
