Thanks James, but that begs the question why is there a plastic bucket in the middle of the turn table?  Is that like the Christmas tree on the top of the steel work of a sky scraper signifying the steel work is completed, or a broom stick on a submarine mast signifying all torpedoes expended?

I'm thinking the bucket is really a 'blockout' so the metal turntable pivot can be installed after the concrete is cured.
What do I win?  ;D

The bucket will be removed prior to pouring.  It contains a screw- perfectly centered- upon which we pivot a string to snap the various radii required to locate the rebar and form work.

See ya

I knew there had to be a good reason other than to see if anyone noticed.

Hi all. I took some pictures of the yard and turntable about two weeks ago. My wife will upload it to Facebook since I'm a techno moron. I tried uploading one here but it was too large. Hopefully you will be able to zoom in on the yard once it's uploaded to Facebook .  I don't do Facebook but I guess I should...what can I say I don' like big brother reading my stuff !  LOL

Most recent batch of turntable pictures. The forms were finished last week and gravel was placed around the bottom of the forms to keep the forms from shifting during the concrete pour. More gravel was placed in and around the hole to allow the concrete trucks to get closer to the forms. Today the forms were coated with release agent and a bonding agent was applied to the top of the footers. We also started drilling the main beams for bolts today.



























Center bearing wheel being turned.



Drilling the main beams for bolts. Two main beams are bolted together to form one assembly for each side of the turntable bridge.



Completed cross members for the turntable bridge staged in the parking lot.

Great Work! Two questions: there will be one more pour after this for the retaining wall?  Will bolts for the center bearing be set in place during the pour or drilled into the concrete later? I am really looking foward to seeing the finished project.

I'd also be careful not to get any dirt inside the forms, particularly the grade beams.
Uh-oh...better get the Shop-Vac!  ;D

The second pour went well today.  Four trucks kept about 10 of us working steady.  Pictures soon.

On the turntable bridge.
Will there be spacers or washers between the 2 timbers of each assembly?
For drainage and drying? Or the wood treatment and being pulled tight together enough?

Is Steve Z carving his initials in the concrete in the penultimate photo?

The timbers will be separated by two bridge washers; this allows the truss rods to sneak through and keeps them from holding water.

See ya
