Almost all the machinery in the Engineers Workshop is powered by the waterwheels, via the lineshaft which spans the yard outside under a canopy.

The workshop is yet another good example of self-sufficiency on the island. The equipment here gave the mill workers the capability to carry out, on site, almost all the repair jobs needed to keep the mill working. The exception was casting, but the Horns had wooden patterns for most parts, which could be sent out to one of the numerous local foundries. (Many of theses patterns can be seen on the walls of the Display Gallery).

The two large lathes are called Centre Lathes, which could be used to turn large sections of line shafting – hence the long frames. Some equipment, the small lathe and the shaper along the south wall, is still in use. Other machinery includes wood turning lathes, pillar drills, grinders, a blacksmith's forge and even a saw that the Horns invented themselves. Unlike modern workshops each machine does not have a motor but is driven by belts connected to a central line shaft.
