Starrett 59A 2 Trammel Heads With 2 Small Divider Points For No. 59 Series Trammel, 6" Point Sizes

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.
