Like the Aerolab, mine will be sealed to the floor.
I'd like to include a remote drain cable but haven't got that figured out yet. At this point that's a "nice to have if I can do it" feature, rather than a "must."
I won't be able to meet with a machinist friend until next week. So I've got a little time to figure this all out. Unavoidably, some parts will need to be machined.
