I bought the article but still don’t know about the nailing of a wide plank. Is there a specific article that addresses this?
You simply nail a Tongue and Groove plank floor in the same manor as a strip floor, using a more beefed up subfloor, as stated in the article. And then go back over the whole floor and either screw and peg, (as described in the article) or use old fashioned cut nails to fasten the ends down. And some on the middle of longer boards. What have I left out, did you want to use square edged lumber instead on the T&G material we normally use for floors. Just what exactly kind of wood do you want to use, be specific so I can give you the answer you can use.
