I truly admire people who can draw, paint and sculpt. I took art all through school but the only thing I've ever been able to draw is the occasional warm bath.

MAKING THE UPPER SECTION OF THE SIDE LEGS: First of all I took a mould of the inner and outer surfaces of the upper leg section in Lab putty.  I wanted to make these parts out of the same plastic as the body section so I could glue them together using standard poly cement. After heating a strip of waste plastic and pressing it into the mould the result was not as good as I had hoped for, the finished parts lacked detail no matter how hot I got the plastic.  After several re-heatings and re-pressings I got something that looked half decent but not to the standard I was hoping for.  After cutting them out and removing the excess material they looked a little better.  But all the re-heating and re-pressing had distorted them too much and the two halves did not match up. Plus it had taken me a couple of hour to make something I didn't like. SO BACK TO THE DRAWING BOARD. As some of you know I am a Prosthetic Dental Technician (I make plastic dentures)  This is a denture processing flask. A wax denture is mounted in the flask surrounded by plaster of paris, the flask is heated until the wax melts and is then washed away, leaving a void in the plaster. An acrylic dough is put into the void and compressed to drive out and bubbles. The flask is then boiled for an hour to cure (harden) the acrylic. After removing from the flask and cutting away the plaster you have an acrylic denture.  Fortunately the flask was just big enough to take the lab putty moulds for both the upper legs. There are two types of acrylic plastic, there's the hot cure type I've already spoken of and there's a cold cure type, which cures at room temperature in about ten minutes. The trouble is the acrylic and the polystyrene are not compatible (they don't want to stick together). On the left the original pattens and on the right the acrylic copies.  Outside of upper legs.  Inside of upper legs. To get around the incompatibility of the two different plastics I inserted a piece of polystyrene plastic into the acrylic whilst it was still soft.  And as you can see the seam between the two halves is almost invisible. Happy now..... Except it's denture pink  ;D |

ATTACKING THE HOOD TO THE BODY: Not much to say this week, I've started assembling the parts previously made.   As you can probably see I've twisted the Hood a little to the left as if the machine were about to take a step in that direction.  This top view shows it a little clearer.  The supporting struts are glued to the body section but not to the Hood, this is because I might decide to twist the Hood even further before I've finished.  More Soon. |

Thanks RB. I started adding the legs today.
This is a lunch time project and I only get an hour for lunch, after cramming a couple of sandwiches down I'm left with about 50 minutes, it's surprising how little you can get done in 50 minutes. ;D

Thanks C.T. I have attached the upper sections of the right and left legs. I'm using a high tensile steel threaded rod... - OK it's a bicycle spoke - to reinforce the legs.   This is not necessarily the angle the finished leg will be in, it's just a rough representation.  The pink leg won't show when finished. ;D   I took the pink out of this photo to give a better idea. |

I've been looking at this picture of my old model, the positioning of the legs and the hood are almost identical to my new model, the walking pose looks quite natural too.  So I shall use this photo as a reference for the new model. I'll have to straighten the bicycle spoke out a bit, this will make the model about an inch taller. |
