Value Line 6 Spline Ring Stretcher & Ring Reducer

Stretches and Reduces Gold & Silver Bands This value line ring stretcher & reducer makes stretching plain wedding ring bands a snap. This upright ring stretcher features a 6-spline graduated in USA ring sizes 1 to 15 stretching mandrel that expands on the downstroke of the handle for stretching non-ferrous metal, non-stone set plain wedding bands.  The 6-spline stretcher has a gentler stretching action that puts less stress on the ring.  Stretching is a gradual act, and not as sudden as it would be with 4-spline ring stretchers. What truly sets this ring stretcher and ring reducer apart from similar looking units from India is the ring reducer plate. This unit has a smooth and polished double sided band reducing plate. Most other ring stretchers/reducers from India have crudely finished plates.  This plate is as good as the Italian versions we see and with care you should have no issues with marring rings while reducing. This plate assists you in slightly compressing and size-shrinking narrow sized domed shaped bands. The plates are double sided with the same range of holes but different in the slope of the depressions with one being more steeply cut than the other.   Operator must carefully inspect bands for previous signs of sizing. Bands that have previously been sized and soldered can easily split apart at the seam if stretching is attempted. Seamless precious metal (gold & platinum) wedding bands can be enlarged using the vertical ring stretcher up in size depending on their thickness. How much they can be stretched depends entirely on the thickness and type of band and the operator. Thin bands size up less than thicker bands.  The reducing plate is used to slightly reduce the size of plain round precious metal (gold, silver and platinum) wedding bands. The size reduction depends on the thickness and width of the band, usually not more than .5 of a USA finger size.  The V-Line Ring Stretcher stands 17" (430mm) tall and has a footprint of 7" (175mm) by 5" (127mm). The base has four mounting holes for securing the ring stretcher to a bench or worktable. Mounting hardware not included. There are no instructions included with this tool. For non-ferrous metals (gold, silver, platinum and palladium etc.) only, not for stretching and reducing steel bands.  Made in India.
