Universal Toroid Winding Cradle
A bench cradle with a tapered double-V pocket. It holds a toroid or ferrite core upright while you wind it. The pocket narrows from 18 mm at the top to 3 mm at the floor, so it wedges cores about 3–18 mm thick, and the 36° end ramps centre any OD from a T-50 (12.7 mm) up to an FT-240 (61 mm). The winding hole stays clear above the 28 mm tall jaws. It also has a 1.5 mm slit to hold the wire tail, and the 110 x 50 mm base takes two M4 or #8 screws through 4.5 mm holes on a 94 mm pitch.
