Hi Guys. I’m new to this forum and could use some advice. I’m building a 17 foot wide, country-style wall unit for my home. There are 5 base cabinets. I’m considering 5/4″ fir boards for the cabinet top. Why fir? Cost and convenience. I don’t have a planer, and fir is readily available at my local big box (I checked the racks yesterday and they had a few 20 foot long quarter-sawn boards). Any reason to NOT use fir for a table top?
Also, the center cabinet is 40″ wide will have a 32″ TV on top. Do you think the 3/4″ plywood cabinet top plus 5/4″ fir would hold that without sagging? I’d prefer to not put verticle supports in the TV cabinet if possible.
