Scraping class 2017 Daenmark

April 2017

In the beginning of 2017 I was asked if I wanted to participate in a scraping class with Richard King as the teacher.
While I knew the basics of scraping and rebuilding I decided to go to the class, as I knew that my scraping was very slow and also prone to time consuming errors. I was hoping that the course will give me confidence in the future to work faster and more precise when rebuilding machines or tooling.
The class was held in Denmark (A week later, a second class was held in Norway), and I had the opportunity to share a summerhouse with Mr. King, Jan – Who organized the course, and Marcus.

Day 1:

On the first day of the class Richard gave as a basic introduction to scraping, his four rules of scraping and some theory. After that we were already working on the cast iron practice pieces, using handscrapers. Everybody was working on his own, and each time something new came up, Richard gathered us together and gave an explanation, for example how to grind the scraper blades correctly.

Different techniques practiced on the cast iron bars:

Until now, we where just practicing the handling of the scraper, using different techniques for roughing or finishing, trying to hit points and so on.
Now Richard showed us how to prepare the surface plate, introduced us to the Canode highspot blue, which is water soluble (And far less mess than the classic oilbased highspot blues like the (in)famous Dykem).
Hinging the part on the surface plate was also demonstrated and how to interpret the combination of hinging and the blued surface. Then we proceeded on to scrape the practice blocks flat:
