The Working of Tortoise Shell
This is a set of three useful craftmanship videos which I was directed to by Emmanuel G. of ArtisanShaving.
A very useful and interesting set of skills for a scale maker and restorer. The heating and steam welding in the videos may? work with horn also. The scraping process used to shape the eyeglasses in videos #2 and #3 is the key to all but the final finishing operations and, even then, on horn and most hard plastic materials I have found that a polished edge scraper will only leave a bit of hand buffing to finish them. A scraper "scrapes" if flat finish honed to a angle less than 90º or it cuts a superfine chip if the edge is burred over to make a microscopic cutting edge. Its shape is to be determined by the job it does. It really is only a piece of metal with a burr rolled onto a polish-honed edge. I used to use a Swaty to do my final honing and a polished drill shank to roll the burr. The back of a Utility throw away blade or even the edge or one half of a scissors makes a good scraper.
The original video did not autoplay the remaining files, so here are links to the series.
