Robin Renzetti just posted a video on how he does scraping using the moore pattern. I am sure most of you have seen his machining work. He does the most high precision work that I have ever scene (not saying much but...) and everything he poss is mind blowing. I guess Moore makes high precision jig grinders and other lab quality tools. His technique is different than Richards, but I don't think they are in the same business at all. Richard rebuilt machines, whereas Robin makes extreme high precision lab quality tooling and measuring equipment. Anyway, there is always more than one way to do something and I am sure you will all find it interesting. I think hus channel is called robrenz but I am sure you can find it.
