The worm and wheel runs smoothly in either direction. Plus there is hardly any backlash. Not bad for a homemade hob to cut the teeth on the wheel gear. Although, I think the deep thread on the worm helps give a robust engagement. The worm and wheel just after I had machined them. The gear wheel … Read more
The Burrell steering column feels like a big step as it adds another level of detail to this tiny miniature traction engine. First of all though a quick look at all of the parts. The steering wheel itself was machined from solid brass. Just 22mm in diameter with a 8BA thread in the centre. The … Read more
A bit of an update on the Burrell steering bottom end. Now this is a miniature traction engine at just 1/20th scale. I use the term scale loosely as this is perhaps what I would say is stand-off scale. This will be apparent when you see this steering system. General Alignment The worm and wheel … Read more
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 … Read more
Creating the Burrell steering wheel was a fun make to get me back into the project. I’ve had some time out on other projects and a sort of hiatus as I generated more drive for this tiny traction engine. Hence, whilst waiting for material for the cylinder I worked on making the small 22mm diameter … Read more
When we talk about Vehicle Steering Systems we’re discussing the collection of components, linkages, etc. which will allow for a vehicle to follow the desired course. This is all part of the vehicle dynamics. The way in which a vehicle steers can be described: Neutral Steering – handling characteristic between understeer and oversteer. Oversteer – … Read more
