Ok another update. Items purchased -
2- 1x6 pine boards 41 inches long
2- 1x4 pine boards 38 inches long
6 - L brackets
12 - bolts (forget size)
12 - locking washers
12 - nuts
12 - short bolts
Ok so I did this. Used the 1x6 and an outside piece and the 1x4 as an inside piece. The 1x4 was centered on the 1x6 to given equal spacing on either side. These board were liquid nailed together then painted with spray can bed liner. Then i lined up the L backets, marked and drilled holes. Then I ran the long bolts from the outside to the inside and nuted them down. I used the short bolts and bolted them down to the base board. I like the head showing so I plan on leaving then exposed. Note the sides you see were liquid nailed down also to help with vibration later on.
Thats pretty much it. I am trying to plan the sides and the top. The top will be removable but i want to make a way to lock it down. I want somegthig that can be removed but not something that is going to wear out from screwing in and out a lot....know what i mean. So I am thinking about that....suggestions? Check the pictures...
