As you can see it looks more like a Mr Whippy Ice-cream than a futuristic device. So i spend all day skimming, waiting for it to dry and then sanding before repeating the process. The handle and botom of the model is dont in the same fashion untill we have what looks like a giant blob of blutak
This Took the best part of three days to get to this stage. The problem with it is that you cannot get a smooth surface by simply slapping the filler on, it's not possible. you have to put some on, Sand it down, find any gaps and then apply more. Now this stuff dries like plaster, so you can imagine the time it takes and the dust it creates. 
At this point i realised i was going to have to make a rather important decision. Did i continue sanding and filling and loose more time on my other projects or did i use CAD/CAM.
Now if you do not know we have a thing called a rapid prototyper in EdgeHill. This lovely piece of equipment looks like an instant coffee machine but can actually print 3D models. While sitting and sanding i worked out that i could probably design the model on 3D software that night and feed it into the machine the next day. This would stop me wasting my life and lungs sanding.
