Simply secure the mandrel in a vise or suitable clamp, slide the ring over the tapered end, and tighten the center bolt with the supplied Allen key. As the mandrel expands, it applies even outward pressure to stretch the ring. Durston also designed the mandrels so they can be used with a lathe or polisher when appropriate. \u003cbr\u003e\u003cbr\u003e\u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003eAt only \u003cstrong\u003e92mm (about 3-5\/8\") long\u003c\/strong\u003e, they're remarkably compact compared with a traditional upright ring stretcher.
