The Grinding Tool

Hi, Anna here. I'm the new editor-in-chief. This is the begining of making the grinding tool. We placed plastic around the mirror and then put the tiles on the mirror. We made a ring around the mirror using the last frosted flakes box. We poured plaster of Paris into the ring. After awhile we have a perfect replica of the shape of our mirror.


Daddy hammering the tiles to form a circle to lay on top of the mirror.

Naming a Blog

Choosing a name for a blog is very difficult and fraught with dangers, but in consulting with Mary Kathryn, my dear bride, we decided on "Kenning through Astronomy Divine."

The name comes from Meditation 6 by Edward Taylor, a New England Puritan, pastor, and physician. Every week he walked hunderds of miles to tend to his flock and care for the sick, and he still had time to be a prolific writer.

About Our Project

In 1978, when I was 12, I bought a book on telescope making at Davis Planetarium in Jackson, MS. It started me on a quest to grind my own telescope mirror. Two years later I order a 6 inch mirror blank and abrasives from Edmund's Scientific only to be crushed when the blank arrived without the abrasives. Edmund's had stopped carrying them. Over the next 30 years, I had thought about grinding that mirror that I had been carrying around for so long. Now as part of a homeschool Astronomy class with my children, we will complete a project 32 years in the making. I hope you all enjoy following our progress in this. We hope that it culminates in February or March with a West Virginia Star Party that will include some of my nieces and nephews.
