The independent jaw design allows each jaw to be adjusted individually, making it well-suited for holding irregularly shaped, non-concentric, or off-center workpieces that a scroll chuck cannot grip reliably. The cast iron body measures 3.1563 inches in length and weighs 56 pounds. The plain back mount style requires a backing plate matched to the lathe spindle, giving the installer full control over final fitment and runout adjustment. A T-wrench is included for jaw actuation.\u003c\/p\u003e\u003cp\u003eThis chuck is intended for use on manual engine lathes and toolroom lathes in machine shops, maintenance facilities, and industrial production environments. The plain back configuration is common on mid-size and large lathes where the operator supplies or machines a custom adapter plate. With a through-hole diameter of 2.9375 inches, the chuck accommodates bar stock and shaft work passed through the spindle bore. Installation and setup are typically performed by a machinist or qualified lathe operator.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIndependent 4-jaw design allows individual jaw adjustment for non-round and eccentric workpiece holding\u003c\/li\u003e\n\u003cli\u003eReversible one-piece solid jaws expand the range of workpiece diameters that can be chucked\u003c\/li\u003e\n\u003cli\u003eCast iron body construction provides rigidity and vibration damping during turning operations\u003c\/li\u003e\n\u003cli\u003ePlain back mount allows machining of a custom adapter plate for precise spindle fitment\u003c\/li\u003e\n\u003cli\u003eThrough-hole diameter of 2.9375 inches supports bar-feed and through-spindle work\u003c\/li\u003e\n\u003cli\u003eT-wrench included for immediate use upon installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a plain back independent 4-jaw chuck for manual engine lathes and toolroom lathes accepting a 10-inch chuck with a plain back adapter plate. Specific spindle compatibility depends on the adapter plate machined or sourced by the installer.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist familiar with lathe chuck mounting procedures. The lathe spindle must be brought to a full stop and the machine locked out before mounting or removing the chuck. A properly machined adapter plate is required to mate the plain back to the lathe spindle nose. Due to the 56-pound weight of this chuck, use a chuck cradle or hoist during mounting to prevent damage to the spindle threads and injury to personnel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChuck Type\u003c\/strong\u003e: Independent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChuck Diameter\u003c\/strong\u003e: 10 inches (254 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Jaws\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Plain Back\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 3.1563 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJaw Height\u003c\/strong\u003e: 1.5781 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrough-Hole Diameter\u003c\/strong\u003e: 2.9375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJaw Pieces\u003c\/strong\u003e: One-Piece\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReversible Jaws\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContents\u003c\/strong\u003e: Solid Reversible Jaws, T-Wrench\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 56 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 429-4010\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689142026546,"sku":"429-4010","price":760.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/985ef23758abab1e0f69306b705fe537.jpg?v=1788255204","url":"https:\/\/voomisupply.com\/products\/value-collection-429-4010-10-in-4-jaw-independent-lathe-chuck","provider":"Voomi Supply","version":"1.0","type":"link"}
