Hand-cranked shaker for closed paint bottles

The four-part shaker contains a base, bottle carriage, 18-tooth eccentric gear and 36-tooth crank gear. The ratio creates two back-and-forth cycles per crank revolution. Choose bottle diameter, socket height, total stroke, strap width and diametral fit clearance. Mount both gears on your own M3 axle bolts with 0.5 mm washers underneath. The eccentric pin enters the carriage’s transverse yoke slot from below. Four M3 guide bolts with washers and suitable spacers retain the carriage on the bosses without clamping it tight. Hold the bottle with your own soft strap through the side openings. Use only small tightly closed bottles of water-based craft paint, turn slowly by hand and secure the assembly against sliding. No automatic mixing time or specific mixing performance is claimed; not for motor drive. Adjustable values: Diameter of your paint bottle: 20–45 mm; Bottle socket height: 12–28 mm; Full shaking stroke: 10–20 mm; Width of your retaining strap: 5–12 mm; Diametral socket clearance: 0.4–1 mm.
