Next up was prepping the small bits for molding, there is the sight, trigger, trigger keeper and the flashlight. I laid down a base of clay and filled in around the parts. The registration keys were then added. All of the sprues will be added in between pours of the two halves.
Finally comes the barrel assembly. The procedure was much same with the other box molds. I had cut out the hard board the serves as a barrier between the two halves. The came filling the gaps with clay. I filled the back side first to provide a solid structure and good bass for filling in the gaps. This way no clay with pop out and let rubber leak. Once again, lessons learned the hard way. Once the back had all be filled, I cleaned up the front added clay in the gaps and using my sculpting tools I made sure that the gaps were smoothed out. All that remains is to cut the rim boards for the two molds? Wax and spray with release and they are ready for rubber. Once the rubber is down she is all done
