Ball towing coupling
Ball towing coupling — assembly drawing
The brief
Produce a complete assembly drawing of a ball towing coupling to AS 1100 — enough for someone to build and check it without needing to ask a question.
What I did
Modelled the assembly and produced a seven-item parts list with per-component masses
Cut section A-A through the tongue and ball to expose the fastener stack, which no external view shows
Added a 5:1 detail because the washer and nut interface is unreadable at sheet scale
Inserted a lock washer and hexagon nut from ISO metric parts catalogue rather than modelling one-offs
Produced an exploded isometric at 1:2 so assembly order reads at a glance
Issued at Rev A with a completed revision block
