Well... yeah. It's scabbed together with scrap lumber I found laying around. Two of the "joists" are very warped pcs of 2x4 from the old run that I tore down 2 years ago. Two of the pieces of plywood are 3/4" remnants my BIL let me have. Under the temporary floor are the stairs to my basement. I needed something to put the step ladder on so I can reach the ceiling.Floor a bit wonky there ?
I currently can't get down to the basement without unscrewing the pc of OSB then dropping down between two joists.
Yesterday, the hardwired smoke detectors kept going off for no particular reason other than to terrify the dogs. I had to go down to the electric panel to turn off the circuit to them but the batteries kept them going.

I found a can of compressed air and hit all three of them with and that blew got out some spider webby dust and they haven't gone off since.
Laundry is off the list until I get the stairwell finished and that will be a few days.
