Wax Sprues that need to be displayed => 18 (not so) simple waxes

 This essay is not for the beginner who has just a few simple waxes to cast. Planning and much thought will make each pattern worthy of being made.

 Many of these patterns have been shown previously on this blog. My expertise of 65 years in this business has given me a different view on wax casting.

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

 This very delicate ring needs to have all of the holes drilled, especially before the casting processes.


 Here are three widths of wax sprues. It's good to have a variety of thicknesses on hand while preparing for these delicate sprues.

 This curved bracelet must be gently attached to the inside hollow wax. Making sure that the sprues are adequately and securely attached and with no spaces as seen here.

 
 As seen in other items, these numbers are the weights of the wax, excluding the numerous wax sprue weights.

 How would you know the desired sprue lengths? I'd secure one end and cut off the unattached end. How easy was this?

 Supposing that there are holes that need filling, I'd use my wax melting pen and fill in the holes one at a time.

 With the same wax pen, secure the sprue to the end of this pendant. Make sure that the melting is thick enough for metal casting.

 The joining of the sprue MUST BE SUFFICIENT FOR METAL CASTING.

  If there are minute defects in and on the new wax, please scrap and inject again.

 

This wax joining is not good!!! Please redo the wax completely.

  Keep the 'wax joining' to the underside of this CAD-created decal.

 I personally like to add additional sprues where needed. My idea is that they are free, so why not use them?


 I prefer to have an 'extra' sprue attached to the inside of the greatly detailed ring. The reason is that this ring needs a complete metal casting with no problems.

 Here is another view of the same ring with the wax sprues attached.

  As there are two delicate pieces to this ring, I'm not looking for casting problems. I'll split the sprues and join underneath.

 Here is my CAD-created dice. I created numerous sprue rods and joined the walls together. There were 6 joining spots.
 I wanted this to be a 'ONE-ONLY' casting. Duplicate injections didn't enter my mind.

 Instead of shaping the ends of the sprues with a file, I thought of another idea. Why not just tightly squeeze the wax sprues with the ends of a pair of pliers? 
 The results are seen here, as care was 100% achieved.
 This idea wasn't taught to me in a textbook, my "Dyslexic" mind overcame many solutions seen throughout this blog.
