The flywheel of the Stirling Engine fits around the flywheel hub and doesn’t do any mechanical work, but...

The crankshaft is the axle that connects the flywheel hub to the piston assembly. It is made of two parts: a...

The clear flywheel is mounted on the flywheel hub, which fits around one side of the crankshaft. It is made on the...

The crankshaft, which attaches to the piston and displacer block, is mounted inside bearings to minimize...

Next up on the Low Temperature Differential Stirling Engine was the displacer block, which was made of foam...

First, I cut a square chunk of foam out of a larger piece. Then I cut a circle of the foam using a nail set into...

I put the rough block into the four-jaw chuck on the lathe to square up the sides: Now with the sized block...

First, using layout fluid and a ruler, I “layed out" the part on a flat piece of aluminum...

For my school science fair, I decided that to make something to help me improve my machining...

Finally, after disassembling, cleaning, sanding, cleaning some more, buffing, cleaning even more, and painting, it...

Mainly, the pulley on the motor’s shaft was secured with a set screw. Over time, this set screw just kept...

After cleaning, it was time to repaint. We bought Rust-oleum Hammered Gold spray paint/rattle cans and...
