3 Wheeler Chassis
It was decided to use a space frame design for the chassis. This was made out if 25mm 16 gauge box section. The cutting list was taken directly from the AutoCAD drawing. This included cutting angles as well as physical sizes. The box section was cut to size and clamped into a wooden jig to keep it in place for welding.
Small metal plates were placed under each join to stop the wood catching light during welding. Oxyacetylene welding was chosen to weld the frame together. This was mainly due to the portability of the kit involved and it was the one method of welding that the whole team felt comfortable in using. Any brackets that required large amounts of heat to be welded were arc welded by our master welder Sid. Sid also did the more difficult and safety critical oxyacetylene welding.
