Rose Engine Lathe. What is it? What does it do?
The Rose Engine Lathe is a mechanical tool that evolved from the geometric lathe around 1790 and functions to engrave circular and curved designs in metal. Used in jewelry design as well as printing patterns impossible to replicate on stamps and money making them difficult to forge, the Rose Engine Lathe is the only machine of its kind that can engrave in curved geometric shapes.

John Jacob Holtzapffel is currently cited for starting a company, Holtzapffel & Co, that leveraged updates to the geometric lathe inventing and creating one of, if not the first, Rose Engine Lathes.
How Does It Work?
The Rose Engine Lathe utilizes a series of spherical gears rotated by the force of a large spindle that is hand or foot cranked. The gears are postioned on a rod and at the end of the rod is a chuck. The gears and the chuck rotate together. The entire unit will rock slightly depending on what gear the artist is using.
The artist will then use hand pressure to apply a cutting device, or bit, against the metal that is set into the chuck. (In the picture above the chuck is out of the image to the right) As the artist hand cranks the rose engine lathe the chuck rotates as well and rocks slightly. If the artist presses the bit against the metal with his/her hand while hand cranking the lathe the engraved pattern can bend and curve depending on the artists settings.
Artistic Design for Royalty
Below is a famous Faberge Egg, a new one hand crafted each year by Peter Carl Fabergé for the Tsar of Russia Alexander III, and then his successor Nicolas II using a rose enging lathe and enamel as the base layer of the egg.
Early watchmakers used the Rose Engine Lathe to produce light bending ornate designs on almost every component of pocket watches and wristwatches. You will not though, find hand crafted engraved art on a watch less than $5000.
Build Your Own Watch is very proud to offer hand engraved art using a Rose Engine Lathe on your watch's rotor as a premium upgrade. There are very few Rose Engine Lathe machines in the United States and even fewer artists who know how to use them.
Rick Bell Meets The Artist
The story how Rick Bell met the Cincinnati Rose Engine Lathe artist is amazing.
Fillling an old wharehouse that used to make this or that, with opaque windows up the formed concrete walls, a Rose Engine Lathe machine artist named Michael Dorsa has been making custom enameled jewelry for years.
Rick happened to be at Findlay Market one day shopping (Our newsletter friends know why he was shopping!) and he wanted to get a gift for his wife. He came across Michael's booth. The patterns on the jewelry instantly made a connection in his mind with watchmaking without even realizing what he was looking at.
When Rick spoke with Michael's assistant she told him he uses a Rose Engine lathe, Rick flipped! He asked to meet the artist right there on the spot. When Michael showed up and met Rick, he took him to see his machine room.
Rick was floored to see these early 1900's Lathe's in action, imagining the watch's they may have cut over the years. He asked Michael if he could cut the rotors on our movements. Michael agreed, and the relationship was born.
Michael went through several iterative designs for our Rotors, and since the Lathe is designed to cut circles, he had a custom chuck created to hold the rotor in the Rose Engine. The end result is two wonderful guilloche designs to choose from for your Series 1 Watch's rotor, Barely and Sine Wave.
