Quotes from Sir Winston Churchill , Sir Henry Royce & Henry Ford

---------------------------------

Whatever is rightly done, however humble, is noble

---------------------------------

The quality is remembered long after the price is forgotten

----------------------------------

Continuous effort - not strength or intelligence - is the key to unlocking our potential.

  ----------------------------------

To improve is to change; to be perfect is to change often.

----------------------------------

We make a living by what we get, but we make a life by what we give.

  ----------------------------------

Thinking is the hardest work there is, which is probably the reason why so few engage in it.

----------------------------------

Quality means doing it right when no one is looking.

----------------------------------

Failure is simply the opportunity to begin again, this time more intelligently.

Jesse Emory Science

The physics and learning potential in a clock is incredible! A clock is a complex machine allowing diverse areas of exploration. Hands-on experimentation can enrich ones concept on the importance of a clock pendulum, its governors, and mechanisms. Additionally one can expand their knowledge on gear ratios, sound, potential, and kinetic energy. Accessing this rich learning experience has been practically difficult until now. Cogworks Set 15 - Jesse Emory Science ~ solves the problem.

 

Cogworks founder, Ian Johnson, and his fascination with gears, prompted his study of wooden works clock movements. Ian found that New Hampshire's Jesse Emory's wooden works clock movements were unsurpassable for that time period. It is incredible to discover a master craftsman, who's work has not been given the recognition is deserves: Jesse Emory made not only the wooden works for each and every clock that he made, but also the clock case, and clock dial.

Shown opposite is our replica Jesse Emory clock.

 

 

 

 

 

Cogworks Specialty Gears & Parts

Cogworks Solid Cherry Module 3 Gears

Cogworks specialty gears and precision wooden parts are used in many mechanical artistic creations around the globe. Gears can be made to customer specifications in hardwood or ply. In hardwood, Sugar Maple (Rock Maple) and Cherry are the most popular. Gears can be bushed with brass to enable fastening easily to a shaft. These standard cherry involute gears shown have a module=3. The module of a gear is the pitch diameter in mm divided by the number of teeth.  The gears have a standard center hole of 6mm or optionally 0.250". Gears can be made from plain sawn lumber or quarter sawn lumber.  Standard hardwood gears from 8 teeth thru 32 teeth can easily be meshed without much concern for humidity. Module 4 and 5 gears are also readily available.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Cogworks " Harrison" Module 5 Gears - Extremely Stable

This range of Module 5 gears features a solid birch laminated core with solid hardwood tooth segments. The tooth segments run along the grain so are extremely stable.  The solid wood teeth look fantastic and are extremely strong. Gears with teeth 12 and below feature a laminated sandwich of birch ply and cherry. Tooth segments can be made from many different woods and even mixed. We use some gears with alternating walnut and hard maple tooth segments in some of our science tools.

We have made this gear style for use in high end displays and are amazed by their  strength and beauty. High end veneers and laminates can be applied to the center of the gear. Gears can be bushed in brass if need to be fastened to a shaft, or if needed to spin on a shaft bushed in black Delrin. Sizes available approx 2" up thru 48".

"Strive for perfection in everything you do. Take the best that exists and make it better. If it doesn’t exist, create it. Accept nothing as nearly right or good enough".
