Built a simple little thumb to help clean up the pines in front of my house and other general use. To keep weight down I made it from 1/4 inch AR400, the weight of the thumb is 41lbs and the cylinder is 18lbs. I need a flow restrictor some kinda bad because it's super jumpy/snappy I'll run by the hydraulic supply store tomorrow and see if they have a orifice restrictor.

Looks good. Can you elaborate on the pivot points on top of the bucket.

Elaborate how sir?

The ears look to be something I could make but I don't know the name and or type of pivot pin nor do I understand the role of plate (I'm assuming) and nut on the end/outside of the ear.
