Hey fellow HHOers!

I was wondering what you are using to attach the Lowes Home Improvement plates to each other, and what spacing you are using. I have tried to assemble them using plastic toilet bowl seat bolts and plastic washers for about 1/8" spacing but the curvature of the plate always produces issues and eventually I lose connection - probably due to either my copper wiring being in the solution, or rust/erosion of the wire connectors... Anybody have any thoughts on the connections, while I'm at it?

Oh, and who all is using Mason Jars - or are you guys using PVC or building your own plexiglas boxes?

Thanks!
