James Fox and Richard Roberts developed the machine into what we call a modern tool in British shops during the late 1810s. George Rennie, Matthew Murray, and Joseph Clement also contributed to this evolution.
Metal planers vary in size from a table dimension of 30 inches by 72 inches up to 20 feet by 62 feet. Their weight ranges from around 20,000 pounds to over 1,000,000 pounds.

Double-housing varieties feature vertical supports on both sides of their long bed. Open-side designs have a vertical support on only one side allowing workpieces to extend beyond the bed.
