This bow compass handles diameters from 1\/8\" to 12\", covering everything from tiny technical details to large geometric constructions with precision that matters for accurate drafting work.\u003c\/p\u003e\n\u003cp\u003eAlvin machines the body from matte silver zinc with fiberglass reinforcement, materials chosen for dimensional stability rather than aesthetics. German manufacturing ensures the adjustment mechanism maintains its calibration through repeated use, eliminating the slippage and drift that plague cheaper compasses. The center wheel locks radius settings securely, so your circles stay consistent across multiple drawings or when matching existing elements.\u003c\/p\u003e\n\u003cp\u003eHard plastic case protects the compass during transport and keeps components organized in your kit. Geometry students working through proofs, architecture students drafting plans, or engineers creating technical drawings all need reliable circle construction. This compass delivers that reliability without the premium price of professional-grade instruments, making it practical for educational settings where tools see heavy daily use yet budgets remain constrained.\u003c\/p\u003e","brand":"Alvin","offers":[{"title":"bow compass","offer_id":47983047901413,"sku":"17417","price":14.2,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.texasart.com\/products\/alvin-introductory-6-bow-compass","provider":"Texas Art Supply","version":"1.0","type":"link"}
