Queen barn wood headboard

I have started making this headboard from some barn wood that I have.
I did an assembly of some of the components before I glued it and put it in the hanging pipe clamps. This is the largest piece that I have used to clamps on. They seem to work real nice.
There are a total of 4 clamps that can be moved across an 8 foot length.
When not in use they attach to a pipe on the ceiling.
I will post more photos in a couple of weeks after the headboard is completed.
