Bill Hudson Posted May 8, 2014 Author Share Posted May 8, 2014 STEAM ENGINE CONSTRUCTION. Making the fly wheel for the mini popcorn wagon. A brass rod was turned down to the correct diameter for the fly wheel. Then several blanks were parted off. A pot chuck was turned to fit the diameter of the blanks. The blanks were then faced on both sides to the correct thickness. The blanks were clamped in the pot chuck and in a chuck on my rotary table. The holes (for sawing) were indexed. The spokes were drawn in on the indexed blank and then sawn out with a jewelers saw. The blank was then placed back in the pot chuck and mounted in the lathe where the rim ans hub were turned on both sides. The wheel spokes were finished filed to shape. Then polished. The patterns for the rest of the engine were also made in brass. All parts were made over size to allow for shrinkage in casting. The engine was then sent to a caster where they were cast in nickel. Below The engine as it now looks. A sad story about the engine. I was showing it to a friend,holding it in the palm of my hand so she could see it. She quickly reached in and picked the engine up by the fly wheel. I said please don't pick it up. She dropped it and it missed my hand and shattered in pieces on the floor. It took some bending to get things right but now the engine does not move when the wheel is turned. Thankfully it doesn't have to turn but I like my stuff to work even if it doesn't need to. 1 Quote Link to comment Share on other sites More sharing options...
