I picked up some better bearings today but short on money for wood.. Might sacrifice one of the wooden bars supporting the mattress on my bed.
Love and light
Look around for a construction site and go dumpster diving. Warehouses also have old pallets out back that are good for lots of wood when broken up.
I can't drive by a full construction dumpster without stopping to check it out. It's like going treasure hunting.
Look under items FOR SALE, Free. Also look under moving sales, yard sales. People always giving away free stuff. Maybe find something made of wood close to you?
The shield should work just fine in your application. You will place it around the N Pole stator magnet sticky point you describe. The shield will be made to allow the N pole field at the 9 o'clock position but not the vertical 12 o'clock position or the 3 o'clock position. What will happen is that when the rotor arm is approaching the vertical position, the pendulum will be left side of vertical with its S pole magnet now in proximity to the N pole field streaming out the left side. They will sense each other and the attraction will accelerate the pendulum S pole towards the N pole stator. You will not get lockup because the N vertical field is blocked by the shield. Inertia will carry it past the vertical position more to the 3 o'clock position. Thus carrying the rotor arm past vertical. The blocked 3 o'clock position of the N stator will not cause any back drag on the S pole of the pendulum, this allowing full extension of the pendulum to the right side. Have the N stator shielded magnet on a bracket to adjust angle for tuning the field streaming out the left side.
Once you get your magnets and experiment building the shield to match your ideas, you will see how this will work. Build the shield just like the video at the start of this thread. A small amount of field vertical is OK. The main thing is the front door open on the left at 9 o'clock and the back door blocked at 3 o'clock positions.
The shield made of mu metal in your example video, I don't think will work for your app. For one thing the polarity in the magnet is different. The mu metal lies across both poles. It is acting the same as a keeper metal across the poles of a horseshoe magnet. In the example, the two poles are exposed. Also thicker metal is hard to work with.
