Bill of Materials

The following is a list of the 32 parts that make up the hydraulic bottle jack. Most pieces are made of steel, that has been shopped in some way, usually on a mill or a lathe. The non steel parts are either rubber or plastic and are purchased or injection molded. The table can be sorted by Part Number, Quantity, Weight, Material, and Manufacturing Process.

Part Number	Name	Quantity	Weight (g)	Function	Material	Manufacturing Process
