(REPEATED ESSAY) WAX CAD CASTING with 11 errors => 12 photos

 These wax injections were made possible with my rubber mold as shown at the end of this essay.

 There are (many) defects in this mould and these were not noticed until a few of the wax injections were made. 

 I found 11 serious problems, what a startling discovery for me.

Between a (CAD) "Computer-Aided-Designed" program and the wax casting, there are a litany of problems.

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

1) The bottom row of holes is not perfectly round, but oval.

2) The underneath displays a 'very uneven' surface that is not conducive to the standard smooth metal castings that we all know about.

 3) There are many holes that are filled with wax, this will become a labour-intensive cleaning process.

4) Many, if not all of the holes are irregularly shaped, some of them are even oval.

 

  

5) Many of the mini-claws are missing, if not, just not well formed.

 7) Here are additional oval-shaped holes that should have to be used for ROUND STONES.

8) In this photo are my '3-claw' drills that I must use to clear the wax for EACH hole. This alone will be a very daunting and time-wasting process.

9) These '3-claw drills' will be 'finger-held' and each will be manually rotated gently 'one hole at a time'.

 10) This is the only way that these holes should be cleaned, being 'very careful' is the epitome of saving the wax forms.

11) As you can see ALL OF THE HOLES HAVE BEEN NICELY OPENED and cleaned of unwanted wax.

 This is the rubber mold culprit that caused so much time to be wasted.

 This 'half of the rubber mold' looked good, but once the wax was injected, this is where the problems were quickly seen. OUCH!

   In closing, I suggest injecting your mold with wax. If you see no problems, then you can go ahead with your metal casting.
