so it looks like i will be redoing the hardwood floors....... anyone want to help?

its going to be a slow process... i am still researching, i have been watching videos on youtube.... doesn't look too bad....

reset the nails, maybe liek 1/8"?

here is what i got so far, use a huge random orbit sander with discs, in a rough grit 80 or so -- then med like dont know #, then finer.... keep it clean and dust free as much as possible..... wipe the floor with alcohol, apply stain/polyurethane... light coats, ample drying time between coats per manufacturer.... usually 3 coats? after the first 2 coats, do a light manual sanding with a fine grit to get out hairs and whatnot (orangepeel) then wipe with a water damp cloth, then do the last coat. then after it dries, put contractors paper to allow it to fully cure
