Cutting a New Gear
This is a photo of a brass gear being cut on a milling machine. The blank gear blank is turned on a lathe to the proper diameter and then placed on the milling machine, held in place with a dividing head. The dividing head is a precision tool that can divide a circle into nearly any number of equal parts. So depending on how many teeth are required, the dividing head turns precisely 1 increment at a time. The cutter cuts a groove and the dividing head then turns the gear to the next position.
In the event that a gear is damaged or worn beyond repair, Time & Again is equipped with the most modern machine tools to fashion a replacement on most medium to large clock movements. This requires a lathe, vertical mill and dividing head along with the proper assortment of cutting tools to properly perform this task. Replacement gears are indistinguishable from their original counterparts.
