Steering Worm and Wheel

Making the steering worm and wheel for the miniature traction engine has been fun. The worm is 6mm diameter and 2mm pitch, the wheel is 14mm in diameter and has 20 teeth.

The following youtube video from my channel covers most of the elements involved in making this gear set.

As you can see from the video, I quite like hand cranking the Hobbymat lathe when it comes to cutting short pieces of threaded bar.
