A band saw machine comprising:

• a pair of column assemblies, each assembly including a column comprising a back portion and two support portions extending therefrom in spaced relationship to one another and in the same general direction;
• means for mounting each said column for pivotable movement about a selected axis;
• and a pair of pulleys for mounting a band saw blade, one of said pulleys being rotatably mounted on each of said support portions;
• support means for supporting said column assemblies, said support means engaging said means for mounting said column of both of said assemblies and disposing said columns in confronting relationship with said support portions thereof inwardly directed toward one another and with said selected axes substantially mutually parallel, said support means also providing support for a workpiece at a location between said column assemblies;
• means for effecting pivoting of said column assemblies on said means for mounting;
• and
• drive means for rotating one of said pulleys of each of said assemblies, whereby the workpiece may be cut simultaneously, from opposite sides, by blades mounted on said column assemblies.
