Brake Wheel | May 28th, 2008 |
On May 28th, 2008, Congressman Rob Wittman joined a swarm of volunteers including
Superintendent Dan Smith and District Director Joe Schumacher to put the finishing
touches on the Brake Wheel of the Yorktown Windmill. The Brake Wheel is the largest
gear in the wind drive assembly --- measuring almost 8 feet across, when all of
teeth and cross members are attached the gear will weigh in excess of 700 pounds.
Our intrepid assemblers were undaunted at the sight of the enormous cog and
immediately sprang into action to wax the teeth and drive them into the carcass.
After the teeth were positioned properly, a retaining pin was driven into the back
of each one to lock it into place.
Because this part of the project was conducted at the National Park Service Visitor
Center, there was no shortage of tourists and spectators. Many visitors to the
Colonial National Historical Park stepped up, grabbed a hammer, and took a turn at
adding a tooth to the gear. In all the project took a little over two hours to
complete and all of the volunteers took justifiable pride in the result.

At the end of the day, Congressman Wittman and Superintendent Smith were each
presented with commemorative 'teeth' from the brake wheel. These pictures show
a few of the great people who participated in the assembly of this monumental
gear.
Of course, there are always a few preparatory steps before the final
product is assembled. These pictures show some of the tricks that were
used to to shape the 450 pound carcass of the brake wheel and to cut
the mortises to receive the teeth.
