Wax Sprues #3 => 7 photos

 These wax sprues are not just simple, easy to cast. Each of them is just beyond difficult. The need is to investigate how the metal will flow once in the metal flask.

                   ================================

  When you are attaching a wax item to the wax sprue, always be cognisant of how the final cleaning will evolve.

 In this highly delicate item, the only place to attach a sprue is at the bottom of the neck.

1) I suggest careful cleaning & polishing before soldering the head to the pendant. 

2) The 'circle of mini-claws' where the gemstones will be set needs to be carefully thought about.

3) The four corners of gemstones will literally be the last items to work with.

4) Polishing of the 'circle of stones and head' must be done before the actual joining of the 3 pieces. This is one of the most 'intricate and carefully planned' items in this extensive collection.

 

 The original sprue that was made is a testament to how the manufacturer thought about the casting processes.

 This disk of gemstones was the basis of my 'Guinness World Record". I wanted to keep all of the claws and not have any of them get destroyed in the casting process.

 Major planning between me and my CAD designer took many hours to plan where the sprues should be placed.

                REVIEW OF PREVIOUS SPRUES.

 Additional wax sprues will give you added help with the flow of metal.

 Never rely upon the wax item to guide the flow of metal.

 

The front of this necklace is where the gemstones will be mounted.

 1) Please inspect every mini-claw to ensure that none of them are missing.

2) Pre-polishing of the separated circle of claws is essential.

3) When you are ready to set the stones, just ensure that the circle doesn't overlap the sides of the pendant.

    

                  IMPORTANT RULE TO REMEMBER

    ALWAYS ALLOW FOR THE "6 PER CENT SHRINKAGE".

 This will occur from the wax to the final and completed construction of your item. Have fun reading this essay. There is so much to read and learn. 

 This is so mind-boggling even for me to remember all of the salient points.
