Ready to pour the Slab Tomorrow

The concrete is arriving at 7:30am, so I decided to do the prep work this arvo...

The plastic is down and the mesh in place on 50mm cups. There's two runs of expansion jointing around the pier: a run of 4" level with the top of the slab and a run of 3" below that to ensure that I don't get concrete underneath the expansion jointing in contact with the pier. Hopefully if the slab does move, it will take the 3" jointing with it anyway...

There are two 32mm conduits with long radius bends in place. One will be for power and the other for signal cables to POD bays north and south of the access door. I chose to line the conduits up with the join in the panels, so if I want to rearrange the bays at any time, or buy more to make a 5 bay POD, the conduits don't foul access into the bays.

The form spacer is bolted down on top of the pier to get the height right while screeding the slab.

There's also a temporary fence around it all, to keep the horses and dogs out of it. I'll drop that in the morning to give the concrete truck access, and put it back afterwards until it's cured.

Al.

Slab Day

The slab is poured.

I tried to finish it as smooth as I could with a steel float. I had to use a plank to bridge across to the pier footing to allow me to reach it all to finish it without an extension float. The finish is a little rough around the pier footing... I started to edge it but then decided that was too difficult to make look good and didn't have a long enough plank to be able to move it get right round the footing....

It's all just a waiting game now....

I'll leave it a few days before stripping the formwork.

I guess I'll fill in my time before the POD arrives by fencing it into the house yard properly.

I've quite enjoyed doing a bit of wheelbarrow astronomy!

Al.

Looking good Al.

It is not long now, is it? A couple more weeks and your POD should arrive.

Great work.

Thanks Matt. A little while to wait... Nov 9 or thereabouts.

They would if I had the POD now, but I've got a little time to let the slab cure .

Looking forward to it!

The Pier is Set

A little more progress today... I set the pier.

The photo shows the little slab extension where the door will be that I cast a few weeks ago as well. I figured the last thing I want to be doing is negotiating a step as well as the low door either in the dark or carrying any heavy astro gear...

The pier is sitting on a 20mm bed of stiff mortar. Leveled it off, slipped the pier on and used the bolts to pull the pier down plumb. After the mortar cures, I'll tighten the anchor bolts to final tension. Should give a nice solid joint to the pier footing.

WoooooHoooooo!!!!!!

My POD has arrived.

Just about to sit down and watch the assembly DVD. I could nearly wear that out between now and Saturday!

The plan is to show lots of restraint and watch the DVD first, then on Saturday morning I'll start painting the inside with black Fusion paint, and assemble it on Saturday... when I will also post photos.

All the bits look good so far.

Al.

What a Day! My POD is Up!

What a day! Whew!

It started yesterday afternoon......

Because I planned to paint the inside of the POD with Krylon Fusion paint to reduce UV and IR (and hence temp build up in the POD) I started masking and painting panels in Friday arvo after work. I managed to get two dome quadrants painted on Friday arvo, using one aerosol can of Fusion per panel.

7:00am Saturday and I was out there doing it again. Wrestling with the breeze, trying to spray paint outside...... How I would love a workshop with a) nothing in it that I was worried about overspraying, and b) enough room to do it without a major removals exercise...

About 10:00am a mate turned up to give me hand putting the POD together... this is a must! I finished off painting the last wall panel, and decided not to paint the inside of the door panel at this stage.

By lunchtime we the two dome halves assembled but without the rubber seals and my offsider had to go...

So I poked about doing what I could by myself, fitting the POD bay wedges for the shelves, then started assembling the walls.

When Lyn got home from shopping we were able to get back into the 2 person tasks.

One minor disappointment was that when we assembled the dome on the walls, it was obvious we didn't do as well as we thought pulling the domes into shape while fitting the flange plates and rubber seal clamping strips.The weather seal is snug right across, but on one side is very tight. That side of the secondary dome just scrapes on the inside of the primary dome. I'm not too sure what can be done about that yet... I may be able to pull the dome off one day and have another go at it, but I suspect that could be very difficult to make the necessary adjustments in screw positions with existing holes there. For the time being I think it will have to do. So if you're about to build your POD - give this lots of attention!

With storms forecast for this afternoon, I was keen to get the POD anchored, which I managed to do by about 7:00pm. I'll have to go back later and install the rubber flange seals between the two dome halves, and fit the shelves to the bays, etc... in the meantime, it's up, it works and its secure!

I must say the quality of the gear supplied by Skyshed is excellent! The stainless steel fittings and rubber backed washers to weather proof the screws for the bay wedges, are all very nice touches.

I must say there is more work in assembing a POD (the first time) than I thought there would be, but after watching the assembly video I figured it was going to be most of the day to do... well I didn't finish in a day, but then I added a few hours work painting onto the schedule...

I've attached a few photos:

1. The assembled dome halves.
2. The bays are keen... they're in position.
3. Walls assembled.
4. View of the inside walls. The bays are black lined from Skyshed, the wall panels are painted with Krylon Fusion.
5. The stainless steel screws and rubber backed washers are just the thing to keep the bays dry.
6. The almost complete POD... open.
7. Another view of the POD open.
8. The POD closed.

Hi Al,

Looks great! I remember seeing one of the prototype POD's a few years ago and was quite impressed with it. A nice installation.

Glad you didn't go for the glow in the dark version! - which I can't understand why anyone would buy?!

Regards,
Rob

Yup! Did I tell you was pretty happy at the moment?

I haven't done much to it today, been out boating with friends, but after I got home this arvo I fitted the black foam seals to dome pivot flanges, and I've managed to improve the rubber seal a bit. It was very tight on one side and had folded under, but I found with a little manipulation I could get the seal rubber pointing out the right way. No need to pull it apart and refit.

Al.
