You wouldn't want, for example, to be sucking smelly air into the "fan chamber" through the joint along the fan chamber and expelling this unfiltered air. Sounds like your's was soundly constructed though, no gaps anywhere

Thanks. It took longer to plan and get the parts together than it took to make the thing from scratch. You're right about the caulking. I thought of that too but wanted the ability to disassemble without any problems from caulked joints. So I used lots of screws instead (I would have probably used lots of screws anyway along with caulking had I used some

). Cheers
