Lost wax casting method LM Cox15 R/C

As I mentioned before, a speed control carburetor to Cox 15 Medallion program was performed today. The adapter piece is made from light metallic material that is used for a motor crank case. This procedure is done by Lost Wax casting method with precision. 2 pieces are made with sheet wax for the crank case and the carburetor promptly, they are combined together and formed firmly. It is set on the rubber setting mount following sprue setting. Then avoiding any bubble formation on the wax pattern, investing material is pored in the casting ring under vibrating condition. Casting would be done in 2 days.
