Making a Mirror takes Hundreds of Hours of Work. Not True! A 6" or 8" mirror should take about 40 to 80 hours of effort. While this is a non-trivial amount of time, the mirror can be completed in a few months, and certainly within a year. Most people work one to three hours a day on their mirror about one or two times a week.

2019-8-19 · Gordon Waite is probably one of the better mirror makers using this machine and have incorporated some of his ideas into my plan. I like the fixed-post plan vs others with eccentric drives, because it gets the heavy grinding done in an automated manner, but still give you the chance to hand-figure.
