Quick update on new engine block

The new block works nicely. At 2 amps, the motor has some of the most torque I’ve seen yet. It was able to continue turning as I attempted to stop the rotor by dragging my finger along its top.

You may notice the wooden shaft collar above the Erector set rotor parts. This is meant to be a cheap and disposable way to permanently fix the 2mm shaft to the Erector set parts, which I don’t want to commit permanently to the project. Two Erector machine screws go¬† up from the bottom of the rotor assembly, through the yellow plate and one of the silver crosspieces, and up into the wood. I used a 1/8″ drill bit to make the holes for these screws, and the holes took the threads from the screws really well.

Here’s the photo from tonight:
