Centrifugal casting consists of producing castings by causing molten metal to solidify in  rotating  moulds.  The  speed  of  the  rotation  and  metal  pouring  rate  vary  with  the alloy and size and shape being cast. The following operations include in centrifugal casting  –  rotation  of  mold  at  a  known  speed,  pouring  the  molten  metal,  proper solidification […]

Cuttlebone casting is an ancient, but very accurate method for one of a kind casting in precious metals or whatever. Cuttlebone is the backbone (sorta) from a cuttlefish. You can find it mail-order,b

Above is a photo of a muller that I designed and built around 12 years ago. I got the idea from a roto tiller and this is basically a rototiller in a drum. Note the legs: The muller was mounted over m

When melting aluminum, the best results are obtained when the melting is rapid. Maintaining molten heel of aluminum in the crucible speeds the melting process. If multiple charges are to be heated, it is good practice to leave 1/3 of the crucible filled with molten aluminum to reduce the thermal shock to the crucible and […]
Old engines fascinate me. I love to restore old machines. Many machines are scrapped because of broken castings, or parts cost more than a working machine is worth. I knew of several machines that could be had for little more than the time spent to recover them…If only I could produce iron castings. After some […]
