Casting spincasting britannia pewter zinc-aluminum silicone lost wax casting Hello, I've been spincasting for a few years using castings primarily for my models and model kits. I spincast mostly Britannia and Resin. I have also spincast zinc-aluminum and wax. I have mold capability of 9"-18"dia. to 1.5" thick. I use both vulcanized and RTV silicone rubber molds. Much of my work has to not only look good but has to fit other parts, sometimes with precision. I am still learning about spincasting and will continue to learn as long as I am spincasting. Until recently I have hand made and machined all of my patterns in brass/wood/plastic. I am in the process of integrating CAD and laser cut wood patterns with my casting. The wood patterns will be used to make a mold to produce production patterns to make the production mold. I am especially interested in learning about vibratory finishing of cast parts. I have a small unit but need to know what media is best and about finishing times. Regards, Jack Mc Kie www.freshwatermodels.net  brass casting

I have been spin casting for a while and I use ceramic. You can get it from Rio Grande in Albuquerque New Mexico. We use the 3/8" grey. We can leave it in over night or for a few hours and not lose detail.
