Polytek Spray on rubber molds

Lester holding arm after we cut it off.  We tied and taped off the arms to keep  from deforming the surface.
This was a very stressful operation but worked out perfectly.

Figure without arms. This makes mold making easier and allows for better results,

Figure laid out to facilitate spray on mold. We supported figure in the middle to keep from deforming it.
We added shims to part the figure in half but I forgot to get pictures of that step.

After spraying, the tool in the foreground is used with cartridges for applying mold material.

Mold material applied, note the flange surrounding the figure creating a parting line for two halves of the mold.
Tomorrow we will be spraying on the plastic mother mold which will give form to the flexible rubber.
This was a stress filled day of very hard work. Everything worked as planned and tonight the rubber is curing so we can proceed to the next step.
