AI Thread Summary
To build a simple gear at home, one can start by scribing a gear shape with straight cut teeth on a piece of brass. A hacksaw is used to remove excess material, followed by drilling a shaft hole and filing the gear to achieve the desired shape. Although this method is time-consuming, it is effective for creating functional gears. Additionally, the discussion mentions gear hobbing as a less high-tech alternative for gear production. Exploring rapid prototyping machines is also suggested for those interested in more advanced techniques.

Hi,
I want to build a simple clock of gears.
How I can build a simple gear at home.
Thank you...

You can scribe a gear (straight cut teeth) on a piece of brass. Use a hacksaw to cut off the bulk of the material, a drill to bore out the shaft hole, and then a file to shave everything down to the final shape. Very time consuming, but it will work non the less.
 
rapid prototyping machine?
 
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
