A simple to build board holder that you can make for around $30. The dearest parts are the left and right hand hinges - you must buy opposites!
It could certainly be improved through the use of box section steel-welded frame and a universal attachment and slide system, go ahead, I'm happy in my simplicity.
Attach the structure to a sturdy post in your carport or balcony. It can be left permanently in place as it takes very little space.
If you need different heights, drill more holes in the support post. it is attached to the post by a 12mm bolt and nut . Nothing fancy here!
I also suggest you have a piece of carpet approx. 2m x 1m to work from. This will protect your feet from the ravages of concrete.
The convenience of this setup is quite addictive and it is hard to walk by without breaking the board.

Easily rotated.


Easy to remove.
