Built for my girlfriend so she can store her vinyls. She expects to acquire a lot of records, which explains it being so long.
I used 4 "Red-Stained Fir Dog Ear Fence Picket" for the running boards ($1.78ea) and 1 "2 in. x 4 in. x 16 ft. #2 Prime Pine Pressure-Treated Lumber" ($8.57ea). I tried to start with a pallet but the quality of mine was too low for indoor use. Any type of wood screws would work as well.
I cut the red fir in half both width and lengthwise for the sides and bottom (4 planks per board) and strips for the sides that will fit a 12.5in record inside. For height I cut the long plank into four 8in beams.
I made it as simply as I could, three beams on all of the walls with the small sides having a 1/2in cut for hand grips. I decided against a middle beam on the bottom because it would have been difficult to drill.
I sanded the whole thing and used a wood burner to add her name and the date. You could add a stain to be very professional but I chose not to.
