I cannot believe that wood supported about 3 tons of freshly poured concrete.

 

Deck is solid. 6" thick with 64 pieces of 1/2 rebar.

I really like the idea of an elevated deck / platform / roof to observe from.

Thanks,

 

As I mentioned I live in Northern Mexico.

 

My objectives were to have a secured place that did not look like an observatory where I could set up several scopes for imaging. 

 

I wanted to be up a little higher to clear the trees.

 

I wanted to be able to start imaging in 15 minutes

 

Wanted to be able to use tripods instead of piers. 

 

Wanted to be able to break my mounts down quickly to travel to darks sites.

 

Wanted to be able to do EEA with my smaller children. 

 

I was surprised the plywood held up the 3 tons of concrete. It was not like watching Niel Armstrong take the first steps on the moon but it was nevertheless quite the striking achievement to see the concrete pour happen. 

 

Total labor down here after the new guy took over about $600. I pay him $6 per hour...what he asked for and a $200 bonus upon completion of the slab. 

 

Will post more pictures later.
