D&M Tools in Twickenham, and their show is always in October. As stated, parking and entry is free and is a great show to visit.
Here's something not often seen from depths of pure applied engineering practice https://youtu.be/9bIHPY99mIY?si=6SKEhdz4viVgQYGCMethod of making and keeping surface plates flat for applications needing that.The blue marks are all hugh spots, made by "blueing" a known reference plate with engineers blue, then rubbing this one across that surface to show the high spots. Those high spots then removed by scraping to refine the surface, ultimately to keep its flat plane as a working plate for workshop use. Part of my apprenticeship in training, we didn't use the power scraper but made our own manual tool, to then manufacture plates.
