What happens here

Leonard presents the half-scale engine block, crankshaft, connecting rods, and pistons. He highlights the meticulous machining required for these components, especially the challenge of drilling precise internal oil passages that are critical for lubrication and engine longevity.

Goal: Showcase the precision machining of the half-scale engine block and its internal parts.

Tools and materials

  • Half-Scale Connecting Rods Custom-made — Displaying intricate machining for size and function
  • Half-Scale Crankshaft Custom-made — Highlighting internal oil passages and precision
  • Half-Scale Engine Block Custom-made — Demonstrating the foundation of the miniature engine
  • Half-Scale Pistons Custom-made/Modified — Showing adaptation from a Yamaha scooter engine
  • Aluminum block — Raw material for the engine block
  • Steel bar stock — Raw material for crankshaft and connecting rods

What they say

Hide

the distributor. This is a small distributor. Benny drilled all the holes and I shaped the rest by hand. I made this distributor. So you started by cutting a piece of plastic for this, or is it painted metal? This is acetal. Do you see this? See how the little valve works? Yes. So, do you need to make some kind of gap on this, or how do you calculate it? Well, you'll give about 4 thousandths of an inch. Here's a little roller pusher. This is incredible. And he comes inside here. You have to pull the pin out, but it goes in here . And then it is fixed in place in the block. This is what I was talking about. And, uh, little spark plugs . Oh my God. Wow. I would never have noticed they were there. I don't think so. These are spark plugs from a model airplane engine, or did you make them yourself?
