Well its been a couple of weeks since my last update on the observatory but the beautiful Scottish summer has been holding me back. I finally got a dry enough period to pour the concrete (but only just) and most of the time it was just a muddy bog. The most upsetting part being that i could not get a machine close enough to the site as they were just sinking in the muddy field adjacent and had to cart all my concrete by wheelbarrow, all 3 tonnes of it!!! Thankfully i had a 1 tonne mixer and a forklift to drop the bags of mix in so that saved me hours of backbreaking work.
The first picture here is after the initial pour and levelling with a scraper board.
The second one here is after polishing of the concrete. Just let it set for about an hpour and a half then, kneeling on a wooden board to spread the weight, rub down the surface with a small wooden block dipped in water using a circular motion. It doesnt give a perfect finish but takes away all the rough spots.
Finally, a quick shot of the pier foundation with my template and mounting bolts. Notice i have made a separate concrete pour with the pier foundation and i intend to remove the wooden formers to that the pier will be completely isolated once i am done which should help to stop any vibration affecting the mount when i start with the photography.
The next update should come soon and will be on the roll off shed itself that i have been working on.
