Interesting that your insulation does not have paper backing. Maybe that's just something they do down there. I would hope you will eventually panel that area to keep the fiberglass particulates contained. That's fairly nasty stuff and over an extended period of time and exposure could lead to silicosis.

Great work on your observatory build. I know few people that could do something like that. A couple of questions if you don't mind. 1. Do you plan to insulate the dome? 2. How was the pier extension coupled to the original pier? Did you drill holes and epoxy rebar into it? Thanks. Great work.

Picked up the wood today for building the staircase from the bottom to the top floor of the observatory. Beautifully seasoned and STRAIGHT cypress.

Can't wait to start working it!

Sorry it's been a while since my last update. Lots of building materials have arrived so it looks like I'm going to be a very busy boy for a few weeks now! Here's what's happening:

Inside fitout begins.

It's been a big week for the observatory this week. I was able to purchase the thin plywood interior wall panelling and even cut some to size and fitted two sheets.

I tested a corner of the cypress slabs I picked up last week by belt-sanding them with some 40 grit to get the saw-marks out of it, then rubbed some raw linseed oil into the test-patch to see the colour. The yellow-gold natural colour takes on a rich red-gold.

I applied by letter to my local government for a large log that one of their services had a stockpile of. To my delight, they approved and happily donated a log.

I found a magnificent pine log, well seasoned with the bark just falling off it. It is my intention to cut it four ways down the length, to cut a post out of the middle of it. The post will be kept aside while the rounded slices will sandwich around the centre pier downstairs, making the pier look like a big tree-trunk. This will then be sanded and rubbed with raw linseed oil, as will the stairs and handrails.

Raw linseed oil won't polymerize (harden).
It will get on your hands whenever you touch the oiled wood.
You want to use boiled linseed oil, which will harden.
Properly dispose of oiling cloths, as they can spontaneously combust.
If it's the look of oiled wood that you like, you might want to consider this formulation:
1/3 Boiled linseed oil
1/3 Spar varnish or polyurethane
1/3 Solvent such as real turpentine or paint thinner
Google for precise instructions for applying, but you basically slop it on, wait, and then wipe off the excess. You can build up coats until you're satisfied with the finish.
It dries faster and works better than plain boiled linseed oil

Thanks Dan. Boiled linseed oil is actually what I have, not raw, so that's great. It's been sitting in my shed for over 10 years. I'm not even sure how it got there. Thanks for the heads up, I'll look into the mixture ratios you've suggested.

It's fibreglass wool, not teeribly dangerous unless you are cutting and ripping it up. As you can see from the last set of photos. It's getting covered up. I can't imagine anyone ever leaving it exposed...

No. Not insulating the dome. Period.

The old pier had threaded studs poking out of the top of it. I simply welded the new rebar to them and continued pouring concrete inside the extension form-work.

There's a good chance it's turned to jelly in 10 years, Baz. <g>
Whatever oiled finish you use, dispose of the cloths in a safe manner. Toss them in a pail of water overnight, unfold and air dry them. They're safe to throw away at that point.
That's some nice looking cypress that you have. Have fun.

Bought 5 litres of new oil today with some turps. This will be fun!

1. Big sanding job! Got one slab of cypress de-barked and sanded down at lunch time. Look at the comparison with the sanded and unsanded slabs!

Debarked and sanded on top and both sides. Ready to make stairs!

1. Cut the hole through the inside and outside walls to fit the tubing for the air conditioner. Cut some steel mesh to size and fitted inside to keep the insects out. Sealed with silicone.

2. Built a small roof over the air-con outlet to stop rain from entering the tube.

3. Air-con fitted into the wall.

This observatory does get better and better every time I look at it. I would have to disagree about the way you mounted the AC exhaust though. I have one of those portable units (looks suspiciously like the on you have and they require minimal obstruction to the airflow to work correctly. The manual gives so many warnings about how much kink you can have in the exhaust pipe before the Aircon looses cooling effectiveness. Try and get hold of one of those clothes driers exhaust covers that automatically open when there is airflow from the AFC unit. When you switch off the AC, the flaps fall to the closed position. That way, the air flows out more freely.

There is no kink. The flexi tubing has been removed and how there is only a 6 inch straight plastic tube straight out the back of the unit to the outside.

Quick update.

I poured a concrete path to lead into the observatory off the main path.

I've been collecting bits of wood on the job at opportune trees we remove or prune. It's taking some time, but I've got some nice bits for handrails and banister. I still need three posts 2.6 metres x 100-150 mm in diameter for the stairs.

Getting there.

Finally I have a finished banner and some variants for the observatory's website to give it a fresh new look. My graphic artist has been tirelessly working with me to come up with a concept together then work his magic!

He's given me a fully-rendered banner, watermarks for the new photos out of the telescope and stuff for embroidery, mugs, t-shirts or whatever!

The new banner is on top of my page below. I'm very happy with it!

As I publish the other variants, I'll show them off.

I've run out of money (looks like for quite a while now) so all I can do is the jobs that cost nothing. Today I sanded down another log for the stair supports then started digging the garden bed. The quality of the dirt is rubbish so I'll have to get rid of it and replace it with some good soil. I also have to dig two trenches in it, one for the drainage pipe near the wall to lay in, plus another on the outside of the bed to run a row of rocks in for the edge.

1. Sanded down log for stair support
Posted Image
2. removed the lawn and weeds to expose the bare clay.

3. Digging in the trench near the slab's edge for the drainage pipe.

4. Starting to lay in the rock edge.

Got busy today and dug the trenches all the way around for the drainage pipe and a row of border rocks.

Started on cutting the underlay to size for the obs and laid it in on the top floor, ready for carpet tomorrow.
