That's when you want to be at HD or Lowe's. And know exactly what you want, i.e., cut the 4x8 to 22 1/2 x 96 and then cut 3 pieces 15x22 1/2, etc, etc. Have then overcut by an eight inch as the panel saws used are not accurate. Square up the box with a framing square when you assemble and sand or plane off the excess. Always, always leave the edge proud of the panel. You DON'T want to sand down a large surface to meet an undercut edge! Each box is just 6 pieces. POC! Seee the archives here and everywhere for tips on bracing, etc. E-mail me or Elektra or Bill or anybody............... Merry Pranks Website
