Man, Texas has had an awful time with the drought. It's a wonder you were able to dig the soil at all! We're starting to dry up over here in Arizona, too; we had a poor monsoon (more like a "non-soon") this past summer and with the La Nina conditions, we haven't had the usual snowfall in the mountains so far this winter.

It's a simple method and it's dead accurate. The Egyptians used it to level their pyramid's foundations.

Yeah, it's been pretty rough. My ground is bare and hay is incredibly expensive. We've had some rain, but not enough to break the drought. I just hope I don't lose any more big oak trees!

Yeah, I'm glad I enlarged over what I'd originally planned. I think it's really going to be comfortable! Of course I recently realized I should probably have made the piers about 3' further apart to give my wife room for her chaise lounge that she likes to use to watch for meteors! 
On the water level, that's what they used when they built my pool years ago and I was impressed with the concept. Just glad I remembered it.

Hi guys! After several months of digging and chipping through tons of Texas limestone, I have the power out to my observatory. Below's a summary of the process, although there are more details on my website. Just click on a picture for more detail.
So the first thing I had to do was replace this disastrous corroded and burnt up little breaker box with something having some room for expansion and a better current rating. This was at the end of January after completing the observatory slab...

And this one will do! I'll never fill it up, but it gives me a 200 amp main.

Hanging the new higher current drop. I didn't plan to do this when I started the day, but after talking to the guys from the power company, it made sense to do it all at once so I didn't have to expand later.

Finished up after a good day's work.

First day of trenching from the observatory site towards the power pole. A friend and co-worker is enjoying his lifelong dream of running a backhoe! Note the jackhammer in front of the backhoe. No chance of just digging through this rock!

After another day of hard work.

And where we're headed...

Another day, a week later, getting through the area between the fence and well house.

After the next weekend, the trenches are connected and extended a bit.


The interesting thing about all this digging was the difference in soil types we dug through. While most is Texas limestone/caliche with some black topsoil, there's also sandstone/sandy soil.
The depth of topsoil and easily diggable (with a backhoe) soil varied from ~0.5 to over four feet. There was even an area with a fissure full of topsoil to full depth. In other areas, there were big boulders in deep topsoil that had to be chipped through.

On the next weekend, I dug up to the driveway where I stopped until I had time to get all the way across and done burying the power lines in one shot.

Before that, I also have to get the trench over to the animal stalls/"barn" where I need to route power and water. Here's where I was at the next weekend.

The next weekend and that trench is quite a bit further:

Taking a few days off to make the cut across the driveway and hitting the hardest rock yet!

And a ways further on the trench to the barn.

Here's the two rolls of wire. The larger is for the observatory's 230 foot run, and the smaller for the 190' to the barn.

That is one LONG trench!

Running the observatory power cable and adding conduit:

Observatory conduit finished...


And then the conduit for the barn:

Covering enough to get the driveway back.

Trench and conduit finished to the barn the next weekend.

Breaker box added in the barn.

And conduit run back to the RV outlet for my trailer.

Here's the rock filter I built at the start of this. It lets me sort between four different rock sizes, from dirt, gravel, and larger.

After a layer of select fill (rock dust & caliche) and rock, I ran water lines to both the observatory location and barn.

Let there be water!

Temporary power connection at the observatory.

Filling in with another layer of select fill and rock.

And finally filling in with topsoil by the first of June!


And what a pile of rock left over! Hopefully I'll still have topsoil after the first good rain (if we ever get any).

After finally completing the power, there was one more thing to do before I could start construction of the observatory proper. I needed to pour the pier footings for the roll-off rails. I decided to go for 16' spans, which will take three laminated 2x12s per beam.
Marking the location of the piers.
The typical hole with the strings for both the slab edge line and the height setting string going diagonal across the hole. The central post hole is at least 3' deep, with about a 16" square hole at the top.
Rebar cage in one of the holes.
Getting ready to pour...
With the summer heat, I had to split the pour across two days. Here's the start of the second day. You can see the post hole digger on the tractor.
The two piers furthest from the slab were done the first day.
And everything was finished off the next day.
Showing each rail line.
Here's the water level I used to get the height.
I finished by covering everything with mulch and cardboard to slow the curing time.
Now, given the summer heat, and just how hard it was to finish this; not to mention everything else I need to do out on the land; I think I'm going to put off the rest of the construction effort until this fall when we actually get some cooler weather!

You've got more gumption than I. I think after encountering that much rock, I would have planted some C4 and blown the whole thing to rock dust! OK, not really. Looking good Beo. Keep us informed. This is fun - building your observatory while sitting here in air conditioned comfort.

Looks like it is all coming together, you've made a great deal of progress. Dealing with rock can be a real challenge...
Although I could use a couple of pickup loads of the bigger rocks there....

High temps have put a hold on my obs too. Fall is looking like a much better idea .
Looking forward to more posts later on.

Hi all. As things are finally cooling off in Central Texas, I'm hoping to get out and start putting up some walls sometime next month. After numerous setbacks where my model kept getting corrupted (backups, backups, backups!), I'm finally just about done and will be posting some detailed pics in the not too distant future. However, I have posted one shot of the way I plan to capture the roof along the entire length of the roll-off.

Basically the plan is to have the top plate on the wall be wider than the rest of the frame, and use a 2x8 across the top of the beam to provide a lip along the entire length of the rail. I can then capture that along the outside edge with an additional 2x8 running down the side and a small piece underneath. Somewhere in there I want to add a continuous brush to prevent pest infiltration, but I'm still worried about having too much friction along the entire length! Thoughts?
Beo
