{"product_id":"fretz-srm-spinner-ring-set","title":"Fretz SRM Spinner Ring Set","description":"\u003cp\u003eThe Fretz SRM Spinner Ring Set gives jewelers and metalsmiths everything needed to create professional two-piece spinner rings with clean, symmetrical flared edges. The set comprises two purpose-built components that work together to flare ring band edges and lock a spinning band in place — a technique that requires precision and the right tooling to execute consistently.\u003c\/p\u003e\n\n\u003cp\u003eThe process begins with the \u003cstrong\u003eSRM-1 concave curved stamping mandrel\u003c\/strong\u003e, which is used to flare one edge of the wider band at a time. By counting hammer blows on the first side and repeating the same number on the second, you maintain symmetry across the flare. Once one side is flared, the narrower spinner ring is slipped over the non-flared end of the wider band. The mandrel is then used again to flare the remaining edge, locking the spinner ring permanently in place.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eSRB-1 two-hole faced steel block\u003c\/strong\u003e supports the ring during the flaring process, allowing the mandrel to pass cleanly through the ring while it is being worked with a stamping hammer. Together, these two tools make spinner ring fabrication repeatable and precise.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwo-component set designed specifically for fabricating spinner rings\u003c\/li\u003e\n\u003cli\u003eSRM-1 concave curved stamping mandrel flares band edges one side at a time\u003c\/li\u003e\n\u003cli\u003eSRB-1 two-hole faced steel block supports the ring and allows mandrel pass-through during hammering\u003c\/li\u003e\n\u003cli\u003eSymmetrical results achieved by counting hammer blows on each side\u003c\/li\u003e\n\u003cli\u003eWorks for both the outer band and the inner spinner ring flaring steps\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eIncludes\u003c\/th\u003e\n\u003ctd\u003eSRM-1 concave curved stamping mandrel and SRB-1 two-hole faced steel block\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eMade in Vietnam\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHammer is not included\u003c\/strong\u003e and must be sourced separately.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Fretz","offers":[{"title":"Default Title","offer_id":43584671613142,"sku":"137.349","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/fretz-srm-spinner-ring-set-otto-frei.jpg?v=1719956037","url":"https:\/\/www.ottofrei.com\/ja\/products\/fretz-srm-spinner-ring-set","provider":"Otto Frei","version":"1.0","type":"link"}
