I make silicon molds of my clay sculptures for casting in resin. Without an expensive vacuum chamber, it is a painstakingly slow process to make certain all the bubbles are out.
I've heard that you can use a pressure pot and a vacuum pump to make your own vacuum chamber and wonder if anyone has tried this and had good results?
I have no problem with building my own as opposed to spending a couple of grand to buy one but need some recommendations.
Currently I brush my clay bed and doll with silicon RTV then I pour from at least 36" to cover and pop bubbles as I see them. This does not always work!
*laughs
Any suggestions?
Thanks!
