Lock Stand to Approximate Safe Door Material
I am building a couple of specialized lock stands for use with my new lock amp. My intent is to A) provide a metal surface to stick the magnetic mic to, and B) approximate the construction of a real door so that sound transfer is about the same.
I bought a couple pieces of 1/2" x 6" x 8" plate steel on ebay ($23 with shipping for two, not bad...). I plan to use those for the front of the "door". My question is what materials I should sandwich between the 1/2 plate and the lock body.
I realize safe construction varies a lot, but what might be some good options? I was considering a 5/8 piece of drywall followed by a piece of thin steel, then the lock body? Or maybe pour a little quickcrete in there to approximate fire clay? Also, seems like the thin steel on the back needs to be connected around the edges to the front since I would assume there is a connection somewhere on a real door and no connection would mean the vibrations would not be transfered from the lock body? Any thoughts besides, "bro, you're crazy" ?
