Considerations Regarding this Tool Post and Its Possible End Uses: There are many considerations regarding this tool post and its possible end uses. Please check the instructions for a complete list. This tool post is designed to be used with our 13″ Mill Table (P/N 50180 or P/N 67050) in place of the crosslide. Other recommended optional equipment includes P/N 1294 Riser Plate in order for your tools to be on centerline with the headstock spindle. While the gang-tooling tool post will mount on the the 6″ and 8″ crosslides, its size renders it unusable on either of these crosslides.
