Short answers, pulled from the story.
When did James Fox and Richard Roberts develop the modern planer machine?
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.
How large can a metal planer table dimension be compared to its weight?
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.
Why do some shops still use older planing machines instead of new technology?
An old machine already paid for holds substantial cost advantage over any new purchase. These massive horizontal grinders often cost too much or prove impractical for specific tasks.
What distinguishes double-housing planers from open-side designs?
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.
