The outside feet were my first experiences with the production of larger silicon moulds.
The basic structure was manufactured from wood. |
|
Some weeks later the master model was finished. |
|
A casting mould from Perspex allows viewing when pouring. |
|
The GRP building method of this part allows the largest possible space for driving motors to be installed later. |
|
This GRP part is extremely light but nevertheless strong. |
|
Once you have one finished silicon mould, the production of the further parts goes much more quickly. |
|
The same procedure with the middle foot. |
|
For this I had to build a mould, too. For more pictures of the middle foot see "silicon moulds". |
|
In order to be able to attach the middle foot, it had to be possible to install a bolt from the outside without it showing. Thus I built one side of the master model without the "half-moon". This missing "half-moon" is now easily made from the opposite side of the silicon mould and this covers the hole needed for the bolt. |
|
Here is the result.

Drive and wheels. |
