I checked out the archive and got some good info : but I’d like some direct advice on my plans for a wide plank floor. Ive got 1/4 sawn red oak 3/4″ thick / 5-8″ wide I want to put down for flooring. A builder friend says I’m nuts : it will cup/crack/gap me senseless.
I figure if it’s on a good 3/4″ ply subfloor, isolated with flooring paper/end biscuited / and nailed every 12″ I’ll be ok. I will make sure that the subfloor and the oak are moisture matched wich means around 9-10 % here (checked with a meter). It will be installed perpendicular to joists 16″ O.C.
Do I also need to screw and plug it to be safe? (and if so at what schedule ? )
I’ve yet to see a firm answer on the “need for underside mill/stress relief slots” on the flooring / I was planning on tongue and grooving with my shaper but have no means to cut the grooves you see on a lot of commercial flooring. Any Ideas?
