SpinOlution 4 oz Orifice Bar

The 4 oz orifice bar for SpinOlution spinning wheels. The orifice bar is the removable piece that completes the flyer assembly and locks the bobbin in place during spinning, attaching to the flyer arms via magnets for SpinOlution's quick-change bobbin system. Available in three interchangeable styles so you can pick the orifice feel that matches your spinning. Choose Your Style Hook: the standard style that ships with every SpinOlution wheel. An open hook orifice that's fully bypassable, allowing complete freedom to spin anything from fine yarns to super bulky or heavily embellished art yarns without snagging or restriction. Tube: a 3D-printed tube with a standard round orifice. The closest match to how most other modern wheel brands set up their orifices, and a familiar feel for spinners coming from another brand. Delta: a 3D-printed tube with a delta-shaped opening engineered to keep yarn centered while spinning. Best suited for fine, precise yarn work. All three styles are interchangeable on the same flyer, so many spinners keep more than one on hand and switch by feel or by yarn type. Compatibility The 4 oz orifice bar fits any 4 oz flyer on a SpinOlution wheel: the Pollywog, Echo, Monarch, Firefly, and Queen Bee. The 4 oz flyer rod is always 1/4 In diameter regardless of wheel age, so no rod-diameter measurement is needed for this size.
