MDF for closet shelving
I'm in th middle of building a large closet organizer with MDF from Home Depot and regretting that I didn't check the grade of it first (light beige sheets). Anyway, anybody happen to know if the 3/4" stuff they stock is LD, MD or HD? It was like $26 a sheet, and my shelves are 14'deep x 28 wide. What kind of sag do you think I'll get over time. It'll be used mainly for light closet stuff like clothing and shoes, etc.
Also, to screw the fixed shelves into the "end grain", what size/kind of screws to you use? I was going to use 1/4 cabinet screws with the wide flat heads, but am thinking that diam. might be too large. I'm thinking instead of using 1 5/8" coarse thread drywall screws + glue, predrilled. Anybody have a preference on this?
