I designed this furnace system back in 1961 for my personal sculpture use. Many tons have been poured and variations for size differences made over the years. This is my current operation after downsizing from a very large 1000 lb capacity melting tilt furnace 30 years ago. I just do not have use for that volume anymore. I have never gotten any burns or had any accidents but I like to promote the safety qualities of this set up. One man can control all the operations with little effort since all the weights are being lifted by the two electric hoists on a single movable bridge crane system over head. The tongs can hold the crucible at an angle while being free to scrape slag or add any additions. The crucible is pin locked into the carrying forks and a dummy post at the other side of the unit allows both up and down, circular movement around it, as well as an extension closer or away from that post area for a distance of 8 more feet. It gives plenty of area to pour any molds anywhere in the sand pit or adjacent floor areas. In addition, should there ever be an accident or need to stop everything and exit the room or put attention somewhere else, the entire crucible and holders will swing back to level and even plug the last cup areas where any metal could ever be bubbling out. It has never happened but it is also why I only pour my own molds after proper and tested burnouts. PS I take the pictures via remote also...HA It is a great day in the neighborhood and I have a sweater on under the reflective wear.

This is a plaster based investment pour cast over the wax pieces inside. I makes for an obvious set of layers to show how much is poured with each mixed batch. One of the reasons for this is to allow each batch layer to start to set and then set up in succession so the wax models will not have a tendency to float or distort in the investing process. One of the batch layers had a small amount or old red latex paint mixed in just to better expose how much was in each batch. It does not affect the mix.
