I went to Lowes today & bought 3 - 2x4’s & 1 sheet of 4x8’ Smooth Brown Hardboard Wall Panel. The panel board was less than $8. I had lowes cut the panel board into 2’ widths. They are probably not all quite 2’ wide. I cut the 2x4’s into 8 - 2’ lenghths & also cut 4 1x2’s the bottom panel stops. I then cut a 3/4" deep slot for the hardboard to slide in. I also cut an 1/8" deep slot in the 1x2’s. I clamped all the 2x4’s onto the table using a 2’ long spacer for each of them so they are all the same height. I then checked the dimensions before finally cutting the hardboard to the proper widths. I just have screw all the 2x4’s in place now. Here is photo of the test fit with 2x4’s clamped in place.
