There are many secrets to a good cast. The most important one being...MIX WELL...but there are a few other things as well. I use clay to make the beds for these molds. One of the things that helps me make a good mold is straight clean lines around the Master.
I spent 3 hours making this simple mold. I have a spot lit magnifying desk top lamp...I use my little pocketknife and trim up, pat down or otherwise trim the outside edge of the part being molded.
Yes its a bitch of a time...but here is where I will spare no expense. I don't care how long it takes...because the time spent here ensures I have a flawless cast...its worth it or all your work goes to shit before you even get started.
Sorry about the pic, but you see how straight and clean it is.
The straighter and cleaner it is, the nicer the cast, the less sanding and ultimately, the less work one needs to do. The suspension mold was needed to make this cast as this cast is my Master. Now I can mold it however I want.
