Description
The No. 59 Series is very useful for laying out and scribing circles beyond the capacity of ordinary dividers. The trammel heads have a clamping device that firmly holds various attachments. The attachments consist of two sizes of calliper legs, 6″, 9-1/2″ (150, 238mm), two sizes of divider points 6″, 9″ (150, 225mm) which are eccentric for close settings and a set of four ball points with holder. The ball points with 6″ (150mm) holder are for scribing circles from the centre of any hole up to 1-1/2″ (38 mm) in diameter. One of the large calliper legs features a joint operated by an eccentric thumb piece for fine adjustments. A pencil may be clamped in either head in place of the calliper legs or divider points. The heads will accommodate any size beam from 3/4 – 1-1/2″ (19-38mm) in width. Since beam length requirements vary widely and they are easy for the user to fashion, we do not furnish a beam.
