Radiator The bodywork around the 'radiator' is probably the most complex panel on the kart. A mock up of the surround was made from MDF so the shape can be tested on the kart. From that a paper template for the alloy sheet was made. This involved a lot of guess work as we don't have a lot of experience with forming aluminium sheet. Nik worked the sheet on the english wheel while comparing the sheet to the shape of the mock up. There is still some fine tuning of the shape to be done but it's really coming along. We found it is useful to anneal the alloy as it work hardens whilst shaping. It's a tricky business as it's very easy to overheat the aluminium.
