Ferrite Toroid Five-Size Stacking Rack
A 142 x 46 mm bench rack with five pegs, one per common toroid size: FT-37 (9.5 mm OD), FT-50 (12.7 mm), FT-82 (21 mm), FT-114 (29 mm) and FT-140 (35.6 mm). Cores stack up to 36 mm high on each peg, and every peg sits in a shallow well 2 mm wider than its core, so you can grab the size you want without digging through a loose drawer.
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.
