Winch To Sprocket Adapter

thingiverse

A 13-tooth sprocket heads to Harbor Freight for a 2500 lb. winch adapter showdown. Don't get too wild with this; just eyeball it and walk away. This sprocket boasts 18.3mm inside diameter and 31.4mm outside diameter, making it a potential H35B13 model (judging by the stamp on its face). I've got a compatible chain lying around somewhere, waiting to be called into action. Unfortunately, I haven't had time to test this against the winch motor yet; priorities are in order after all. High-torque winch motors can easily shatter a thin-walled PLA plastic adapter and send any attached load flying - along with your favorite body part. To assemble, simply remove the planetary gear assembly from the winch motor and marvel at the perfect fit between the sprocket keyway and the winch motor shaft. Go ahead, take it for a spin... but only if you're feeling reckless!
