First saw two 1.20 m long pieces from a squared timber with a length of 4.40 m. Now place the two shorter squared timbers flat on the floor, place the two longer ones on top at both ends and screw two 20 mm hexagon head screws with washers through the frame at each support point.

To mount the frame in the tree, find one The most suitable, stable location with thick branches and trunks out of. It is particularly important that the Support surface is in balance.
