I want to make an acoustic barrier which include about 6-8 square feet of 1/4" lead. Normally when making such a barrier, it is desirable to solder it together so that there is a tight fit between the panels and no gap where sound can get through. However, in this case I will need to move the barrier to service the equipment it is shielding about once per year. If I solder together the whole barrier it will be very heavy, about 150-200 pounds, and difficult to move.
So, I need some way to connect the lead sheets together tightly, but in a way that they can be easily disconnected into smaller panels that are easily movable. Any ideas how to do this?
(Note that the barrier will not just be lead sheet, it will have a sound absorber like drywall or plywood bonded on both sides to it. However, the absorbers do not need to be tightly connected, only the lead does.)
