Projects | ||
Tile-On-Plaster Tools  | Rather than using a glass tool for grinding and polishing, try using a plaster or concrete based tool. | |
Techniques | ||
| The "Dykem" Test | This is a variation on the "Sharpie Test" that I've developed to determine both quality of contact and number of pits remaining during fine grinding. | |
|
The Dall Null Test
| When making non-spherical optics, a null test allows you to directly see how close you are to finishing. The Dall Null Test is one of the easier null tests to set up and use effectively. | |
|
Making Pitch Laps
| There are as many ways to make a pitch lap for polishing as there are ATM's. This project shows the method that works best for me. | |
