I too am a carpenter and built houses and decks for several years and the decking here is called five quarter decking and yes it actually measures about an inch. You can go to any lumber yard here and ask for five quarter decking and they will know exactly what you want. Just like when you get a 2X4 are you expecting a piece that measures 2" X 4" well you won't get it except in rough cut. I used to start once the foundation was done and leave when it was framed, roofed, sided, doors and windows in. Don't know what that decking is called in other parts of the country but I can tell you beyond a shadow of a doubt that it is called 5/4 here.I still have my chop box,radial arm saw, table saws,worm drive circular saw, couple std circular saws, and 8" circular saw, hand tools for 5 guys more or less ,sawzalls ,drills etc.... Never had any air tools or done any metal stud work and once they started oriented strand board and the engineered studs and micro lam beams I quit the business. Been a carpenter and mechanic my whole life. Grew up with a complete wood shop and a complete metal shop in the barn. We used to build liquid ox. trailers in the barn among other stuff. It was mt grand fathers business and he also designed and built much of the machinery that went into Bethlehem Steel when it was built.
