Octagon Port 1 construction UPDATE.....

Finished off bending the second plate up, for the other half of the wall surround. Depending on how R5's skin is constructed, will determin how much needs to be shaved off the Octagon's walls.
(As they should be curved to fit the diameter of R5's body).

Next I machined the centre diameter part. This has a screw thread in the back to secure it and the support bracket, which locates it onto R5's base.

The next part is to mask off the parts that need painting blue and after this, the parts will be glued, bolted together and secured to R5's base.
