As I'm going Airstreaming for a few days, I thought I would give a quick update.
For the last week, I've been removing the subfloor. I've got about 5 feet left. I think I now have a system figured out. Ugh. I guess it's good to know for the future.
What I have found is that your circular saw set to just a hair under 3/4" is your friend. Cutting with this tool is easy. Sawzalls thru elevator bolts, not so much.
My "system" is to rip two cuts north/south straight down the middle about 3 inches apart. Chances are you will miss all the bolts. Now remove that woodto expost the exact location of the crossmembers.
Now rip directly east/west on top of each side of the steel crossmembers. You should now have panels falling apart with a little prying. The thin plywood strips on top of the frames will easily snap or cut away from the bolts with the sawzall.
Now the bolts are exposed and can be easily cut off with a grinder.
This is a lot of cutting, but I've found it easier than manhandling the floor.
We are off to Lancaster Ohio with NOVA and other WBCCI clubs this weekend. I need the break!
