Wooden 1st Stage Piston Pattern Foundry Mold!

 This one of a kind original decorative wood pattern was hand crafted by expert industrial craftsmen of yesteryear. The pattern maker was the “artist” of the industry. First was the dream, then the drawing (blue print), then the wood pattern, then the metal casting to be machined to the finished product. The wood pattern had to be made to strict tolerances else the finished product would be off thus scrapped. This is what makes these patterns so beautiful; they were made to precision the old fashioned timely way! They were not massed produced but one of a kind!  

This pattern was used in the foundry process to produce a " 

Piston shape is very unique! Once casted the part will go on an engine lathe to be machined, Piston ring grooves will be machined around the parameter. A hole will be drilled in the center for the piston rod. Ribs are for strength and to reduce the overall weight of the piston. Pistons are used are used on Steam Engines, Steam Driven Compressors and other drive types (Electric, Diesel, etc). 

Pattern is hard wood, most likely mahogany. Pattern is Approx. 12" in diameter at it's widest at the base. x 11" Tall.
