1 Part Down - 9 to go....

The body sculpt has been competed, it has been textured, smoothed but not baked off (as sculpy usually is) The reason being, modifications can be made easily if the mould fails, and the bottom jaw will probably break off when de moulding ... But can easily be blended back in.

The mould

To begin the body mould was made using a standard condensation cure silicone. So that fast cast replica's can be used for the following reasons.

-Base for sculpting additional limbs and parts.
-Painting tests
-Casting tests
-To be used when moulding with Transil 40

The oils from the sculpey may inhibit the platinum silicone, so a lacquered fast cast version will be used to prevent this contamination.

Mould Studs
I attempted a new moulding method. The mould studs (from mould life) are used within the silicone to perfectly locate two part moulds. The image shows a piece of plastic being used to created the split line with punched holes containing the studs. The plastic covers the entire seem up to 5mm away from the shape.

-problem - My original intention was to have the split line running around the seem of the spiders body where the top meets the bottom. thus easily hiding any flashing. But when pouring the clear plastic lifted slightly, and the split line is now across the spider eye cluster..

Other than that it was a very quick successful mould, we will see on Monday the extent of the split line. But it should be easily hidden.....
