I want to build a humidity proof box that opens on hinges. What's the best way to seal the parts that open?
I bought a cheap old guitar and spent way too much on an amp (it was a great deal for what it was) to learn on. They live in my garage so my wife won't find out. The problem is my garage floods whenever it rains, the rollup door is broken and lets water in.
There's a floor drain and a dehumidifier, but sometimes it can still get pretty humid in there if it's flooding in the summer.
I've looked at dryboxes for the amp, but they're several hundred dollars. Probably double what I paid for the amp for one it will fit in.
I'd like to make one suited to this application. I was thinking I'd caulk the seams and add a vented false bottom with loose dessicant beads inside and put it on casters to raise it up off the floor. The front and top would open on hinges so the speaker and knobs are exposed but it could be used still sitting in the box. Maybe even a flap on the back to access the power cord.
The opening is where I'm stuck. What's the best way to keep humidity out of the opening parts where the edges meet?
I was thinking some kind of weatherstripping but that's not a perfect seal and relies on the door jamb usually to make a seal at all, and I don't want to have to build it out so far to make that work. Any suggestions are appreciated.
