Fig. 11 James Watt’s first experimental setup of a separate condenser
tray full of water above the piston kept the gap sealed. But such an arrangement using
water seal was not allowed to avoid any contact of the cylinder wall with cold water.
John Wilkinson was the greatest ironmaster of his generation. He devised a new
method of boring cylinders. Figure 12 shows the new version of boring mill developed
