When a project requires a complex parting line, it is often easier to pour the entire mold in one process with clear rubber, then cut your parting line. This process also saves at least a day in creating the mold.

Slightly over explained but VERY COOOOOOL
I can totally do this at home! Now where did i leave my vac chamber and pressure pot....
I enjoyed you INSTRUCTABLE very much. I had not seen the "bombs away method" before; that will be useful. Thank you for that tip. Is it possible to build a vacuum degassing unit? As you pointed out, they are not very economical if purchased outright. I will be molding small items. I thought of building one out of a standard 1 gal paint can and an expended food saver vacuum type product. I do not know much else regarding the necessary mechanics of the unit though. Any help, or link to a ‘how to would” be appreciated. Thank you – Avasar10000
Awesome time saver, I have been using transparent silicone rubber from <a rel="nofollow" href="http://rubbersheetroll.com/silicone_rubber.htm">rubber sheet roll</a>. I was press molding two sides of the part bu this makes way more sense. <br/>
ok now this is great! (+)
