This Pallet Sit/Stand Desk that is almost finished. I'm actively searching for the right gas struts. The struts I want to use are like what you see on old camper shells or some car hoods. The struts will attach to the sides of the legs. The hopeful outcome will enable the user to release a small latch to raise the tabletop to a determined height; I want this table to be adjustable like an office chair is. I looked into using linear actuators, but the cost was out of this world!!! I am also pondering the idea of possibly using a hand crank to raise the top but wanted to share my table design. I'll post updates as I work out my prototype.
My Prototype Pallet Sit/Stand Desk - tabletop:
I started by using a table saw to strip the pallet 2x4 were into 1x2's for the frame and secured it together. Next, I laid the frame out on the floor of my garage. Then I began placing different pallet boards in and cut the boards to complete the "puzzle." This also made sure I did not have to go thru an enormous amount of time planing the boards. I used wood glue across the entire backside of the tabletop, ensuring I filled in all the cracks and crevices. Then I filled in any small gaps with trimmings and even sawdust from my shop floor. I set it aside to dry.
My Prototype Pallet Sit/Stand Desk - finishing the frame:
I used a finish nailer to attach the 3/4" piece of birch plywood I had salvaged from an industrial complex near my house to the back of the frame. This allowed the center to be somewhat hollow because of the different thicknesses of planks used for the top. Additionally, this made the table top lighter with the goal being the ability to adjust the height. Then, I scrounged up 4x4' boards that I salvaged and created the basis. I stained and then sanded lightly to give it a weathered finish. I sealed it with a polyurethane varnish. Hope this inspires.
