5.2 Instructions
1. Firstly the two shafts (Part C) are
placed at either end of one of the
right angle sections (Part B). They
should be positioned so that the
shafts protrude by 140 mm
(including the 40mm thread) and
are then welded in place.
2. The second length of angle iron
(Part B) is used to form a square
cross – section (see diagram 11).
This is then welded in position both
to the axle shafts and the other
piece of angle iron.
