I'm sending this out to the list as well as to Meetup.
I'll be down at RMM today around 13:30 to work on pulling up the subflooring in the back.
Andrew will then proceed with the rest of the repairs.
Note that this is
A) slightly dangerous work on approximately the level of working under a car
B) probably physically taxing (there will be some lifting and demo)
C) not something that can be handled by too many people at once (the floor stability is unknown)
I will need exactly one other person in the room with me during the floor cut for assistance and at least one other in the adjoining rooms and/or outside for safety and demolished material extraction.
If you're coming you'll need:
B) Long Pants
C) Close-fitting long shirt sleeves
D) Eye protection
Tools that will be useful are small prybars, large prybar or a Hooligan tool, and claw hammers. I think I have everything else we'll need.
Note that when *we* are finished, there will likely be a large and impassible hole in the floor so securing the rear room is essential.
