This second part covers a lot of ground but the techniques can be used for complex
projects. To demonstrate how to make a two part mold I’ve decided to mold a tube which
could be use to make charge pipes, etc.
All the usual disclaimers_the chemicals are hazardous so use adequate protection. This
tutorial is how I do it. There are other methods which may be superior. If you choose to
try these procedures its at your own risk.
First I wax the part thoroughly will mold release wax. I put on at least six coats. Wait till
each coat dries and buff. I use clay to form my parting lines along with foam
I cut the clay into long strips which will be applied to the
part.
This is followed by the foam board which is pressed firmly against the clay and the back
size is hot glued to the part. Important is the parting line is placed on each center line of the tube.
