On 3rd of January 2011, I began my telescope making journey. It is still a work in progress. These pages are the chronicle of that journey.

 

One day I will finish!

Almost done grinding

Urban Astronomer avatarPosted on 13 February, 2012 by Allen Versfeld

These finer grits are very fast indeed – for the first time, I brought home supplies of two separate grades, and if I can find time to work over the next two weeks I should be able to complete grinding and begin polishing next time I go to the class! It was an interesting class this last Saturday.  Not only did I confirm that the #400 grit had left me with an apparently flawless pit-free surface, but there were a … Continue reading →

That was quick

I had a lucky break this evening, in that my wife has taken the kids to her sister’s place leaving me with a sleeping baby and time to grind glass.  I spread newspaper out on the kitchen table, laid out my kit and started grinding with #400 carborundum.  After a little less than an hour, I dried off the mirror and set it up on the latest makeshift testing station.  Our dining room table is a round four-seater with a … Continue reading →

I’m back, baby!

At last, I’ve got grit under my fingernails and fingers that can no longer operate a capacitive touch-screen phone (Seriously.  3 hours of exposure to silicon carbide, ground glass and a detergent-glycerin-water mixture have done something weird to my fingers so that my phone no longer thinks they’re human.  ooooh…..), and as a bonus I moved on to the next finer grade of abrasive! So I arrived at the class this afternoon, dodged a thunderstorm getting my mirror making kit … Continue reading →

New beginnings

Urban Astronomer avatarPosted on 23 January, 2012 by Allen Versfeld

Hello?  Anybody still reading this thing?  If you’ve given up on me and my project, I couldn’t blame you.  Things have been pretty silent for a long time now, for reasons I’ve gone into in more than enough details previously.  However, over the coming week I’ll be unpacking my mirror, reclaiming my bucket and spray bottle from the housekeeper’s cleaning cupboard, and preparing to pay a visit to the ATM class this saturday.  Meanwhile, I’m hoping to put in a … Continue reading →

The telescope making class, now on TV

Urban Astronomer avatarPosted on 20 November, 2011 by Allen Versfeld

I haven’t been to class in a very long time.  So long that I couldn’t say if it was even still running!  Fortunately, they made an appearance on the Afrikaans language magazine show Pasella, to a national audience, which confirms that they’ve continued operating as normal, even while I languish at home (and at work, and in exam halls, and…).  If you’d like to see some of the faces who’ve done their part to instruct and motivate me, watch the … Continue reading →
