Finishing the clay

Design almost finalised

With the design almost finalised, it’s time to copy it accross to the right hand side

Having gotten the design to a place I was mostly happy, it was time for finishing the clay and to copy the design over to the right hand side. It would undoubtedly need some tweaking, but once you can see both sides it’s far easier to make a good judgement.

Copying over symmetrically can be a bitch of a job unless you have access to a surface plate with measuring machines… which thankfully I did – I managed to convince my clay modelling agent to let me use a plate they have in their facility that goes unused most of the time. So, one saturday morning, I loaded the bike into a van to take it over to their studio.

The clay isn’t perfect at this stage – there are several things that will need finishing in the first prototype part – for instance the seat frame is protruding through the clay on both sides, which will need to be fixed. Many of the smaller radiuses are also left sharp, as these can be easily and accurately added in the hard part.SV025

In the next post I’ll be starting the process of taking a mould from the clay!
