RE: [gingery_machines] new article: Making it Dead Flat and Square

 

Matthew,

I just read a bit about Whitworth and he certainly did a lot of impressive things. I could not find any reference to him inventing this procedure and would have thought it dated back to maybe the Greeks. Do you have a reference I can use in the article?

I was thinking about mentioned the 3 plate method but decided that was too much for one article. VERY cool stuff!

Have a Happy New Year!

Rick

Rick,

Thank you for a nice clear explanation! This technique was invented in the nineteenth century by Whitworth and was the basis of modern precision machine tool making. Amazing precision can be gained using scraping and the three plate method. Whitworth was an interesting man, one of those that contributed a lot to the industrial revolution. He was working with the same basic tooling and materials (with the exception of Al which came later in usable quantities) as we are!

Many thanks for your clearly explained contributions to this group. I always enjoy reading your pieces.

Regards, Matthew

Matthew TINKER
