Is there any rule of thumb for how many times you can sand 3/4 red oak strip floors? -before you get to the tongue.

I'd be guessing some where around 20, but i have absolutly no clue whatsoever
yep I change my oil every 3000
miles or when I get bored...
which ever comes first
but more than 4 or 5?
wow, really? how much do you take off when sanding

enough.The sander does three things - flatten the floor, remove scratches, and make it smooth for the new finish.Usually on most work there is not too much flattening, but it can vary job to job. First time is when you normally deal with thatScratches can go deep, but you need to take a floor down enough to get rid of them. Other floors might have no scratches to speak of, just wear and tear.so - it depends.I have torn out old flooring a hundred years old or so that still had 3/16" above the tongue, and others that had been sanded to within a paper thin sliver, where the previous finish coat was acting like a glue and all that was holding it in place over the tongue.One job that we refinished had been walked on with golf shoes from front door to the side vestibule where they say to remove them - a sin on an otherwise beautiful floor. We just barely saved it, but you can see where it got sanded deeper where we removed more at the entry if you know what you are looking at.

3-4 times.
Something between three and ten, depending...

Yes, it depends on a lot of things such as how flat the floor was lain and the level of the frame under it and even how flat it's sanded. But the most important thing is the type of material it is finished with.
If it has 3 coats of shellac and then a coat or 2 of varnish on it you will need to use # 4 grit and shred it probably crossways or diagonally the first cut. You'll probably carry out a 50 lb bag of sawdust out of a 150' room.
If it has oil stain and 2 coats of urethane you can save the rough cut with the # 4 grit and probably carry out half as much saw dust.
Any way I'll say that you should get 5 sandings in the worst case and at least 10 in the other. I think I could streych it to 15.
4-5 times, remember, that there is only 1/4" of wood before the tongue/groove. And it's not the tongue to worry about , it's the groove side that will become thin and split into sharp toe-biting blades. 4-5 times at best, and that's with a well laid floor. You don't want to get too close to the groove, you need at least 1/8 to remain on the groove side or it WILL start to split over time. Now that I cogitate more (just got up and having coffee) I will back-up and recommend only 2-3 sandings to remain a good floor. Now back to get the second cup-a-java, then finish 3 proposals for today. Good day all ! Bill D. Quality Wood Chips.

Just to throw a hook into the works.. You can more than double that for my floor..
Three reasons for that.. first the back side of my boards are rough only the top is smooth thus my flooring is more than 7/8ths thick. Second I moved the tongue and groove down on my flooring to gain additional sandings. Third I shellaced my floors so to remove my finish I simply would need to wipe off the shellac with denatured alcohol. thus avoiding virtually all sandings in the first place..
If your floor is questionable it's probably a much better idea to simply scuff the surface and add a few new coats of finish.
We have many old floors in our historic distric that are either in great shape if the owners simply had maintence coats applied over the years, or are shot if the floor finishers are allowed to full sand when adding a new finish.
