This is my first attempt at a homemade tripod head, it is made from a wall plate strap available from most DIY sheds or builders merchants.
I basically got a spare tripod quick release plate replaced the bolt with an longer one and used one of the existing holes in the strap to fix it to the mount, then drilled some extra holes in the piece attached to the camera so adjustment can be made for different cameras and lenses.
I then offered the two pieces together and marked and drilled holes to fix them with washers between for smoother adjustment.
I then trimmed the bar attached to the camera so not to add unnecessary weight to it and tightened everything up with spanners and attached the camera using the original bolt removed from the mounting plate.
Here is a test 5 shot panorama taken in the garage.
