Below is a scan of my Delta-Cad drawing, which includes sheet layouts for cutting the MDF pieces and 5mm Oak plywood sheathing. The beam-splitter bass cabinet is complex and time-consuming to build, so I don't recommend it for anyone not experienced with woodworking. I never got around to fully dimensioning the drawing but all the pieces are drawn and anyone who has the DeltaCad software (about $40 to download) can easily dimension any feature on the drawing. I will email the drawing file to anyone who wants it-- just email a request to Jazzman1953@gmail.com
