3.2.1. Joiner Fitting
Difficulty in inserting joiners to frame tubes can be resolved by
inverting the tube and tapping the internal joiner against a scrap
piece of wood.
To align the joiner holes with the holes in the frame tube, take the
large 8mm Allen key and insert it into the top hole in the joiner tube
then twist until the holes align. If further alignment is required, remove
the Allen key and place it through the holes in the joiner and the
tube. Use the Allen key to leverage the holes into alignment.
