Re: Great Dane excavating co.
Model man, I'm aiming for a casting just like you did yours. As far as the degassing, only the resin/urethane / whatever you are mixing gets vacuumed for about 90 seconds. Not the mold or poured mold. Once the resin pulls a vaccine (rises in the vacuume chamber and falls, like a bad loaf of bread, the resin is ready to be poured into mold. From what I've read so far just some well thought out pour holes and some hand tapping will release any bubbles on the mold. Most of the little bubbles are from mixing the resins together , that what the vacuume / degassing is supposta eliminate.
Modelman what hardness were those tires? I got stuff coming and the first one I'm starting with shore hardness of 60, it is said to be like sneaker tread. It may be a bit harder but it's a solid tire and pretty high sidewall.
