I love my hardwood floor!! - Revisit to Household tips by Grumpy

Notice the angle of the nailer,,That white part is what holds the nails.....You're gonna need a Finish gun to nail down the first 4-5 courses and the last 4+ courses. The first 2 will probably have to be nailed through the top Into the joists (depending How big those heaters are) the next few you'll have to use the finish gun and nail through the toungue (not straight down, but at an angle so It doesn't destroy the tounge yet below the finished level of the board) then You can go nuts with the floor nailer (8"-12" apart is fine)

More with this Pic.

Notice how this guy started in the middle of the room.....For him to run the boards behind him, he's going to have to make a tounge out of pine or any kind of shit he has laying around.1/4 thick x 7/16ths (Table saw) It should fit snuggly into the (groove) courses he already has down and enough should stick out to receive the piece thats going to butt to it. (called a spline ) If not it'll be a spot in the floor where it will buckle, or raise. He could always nail it down through the top,,But that looks like shit.

Ok...He probably has a table saw set up somewhere in that room also to rip down the pieces that go up against the wall,Splines, around the doorways, and if theres any jogs in the room. A miterbox is fine for straight cuts but it isn't worth shit ripping down a 4' piece that wont fit cause you need an 1"1/4 piece when they come 2" 1/4..

Theres alot more to it, than just putting boards down
acclimating the wood before you lay it. typing of which,,,thats spot where you said cold underneath warm above= frost. i would suggest insulating that cold spot first. Paper will only handle so much moisture before it fails. then the floor will buckle up and cup and just look like shit.
spacing against the walls.
threshholds.
door trim.
gaps in the joints. etc etc etc

tools
finish gun
nail set
compressor
table saw
circular saw,if you're good with the table and miter saw you wont need the circular or jig saw.
Chalkline
back brace etc etc etc
