This is a very well made machine for casting high melting point metals. Motor driven so no worry about winding & releasing a spring. 115v Baldor motor & drive. Also much safer being completely enclosed - As soon as you remove your torch & close the lid, it will begin to spin, & will run till power is shut off or the lid is opened. I got this a while back but haven't been able to find the space to use it properly. Came from the dental castings industry but is also suitable for any small jewelry castings like rings & pendants, etc. Also comes with 2 tins of super high-heat casting investment - The stuff that costs at least 5x more than regular investment. It is quite old but both tins were never opened, and also serve as good weights for the machine till you use them up ! A group of small crucibles are included but they're well used & heavily fluxed - may want to get new ones soon. Counter weights for casting arm are included (I think they missed the photo shoot). 3-page manual; it's a very straight-forward machine! It has just been moved outside, under our gazebo, for easy viewing.. $300
