Bending the rail is relatively easy. Just use the bender to bring the rail in to the line marked on the cement. The hardest or most frustrating part is continuing to work and re work the rail until it is in the shape you need.

As of yesterday, outer wheel blocks still need to be installed before turning the TT over.  Latest "rumor" is that crane will not be until Wednesday.  Check with those that know about crane schedule.

With this message, I am trying to post a photo of Thomas at Chama.  Don't know if I will be successful...

Here are the rest







Pictures are small but they appear to use two rails, without ties, bolted together in gauge as a ramp

The turntable bridge was flipped over today and set on blocking next to the bearing pedestal.  The next work will be building the spider wheel assembly so the bridge can be placed on the pedestal.

Turntable update.

The ring rail on the underside of the turntable is complete.



The ring rail and female end of the center pin have been installed on the center bearing foundation.



The outer wheels have been installed on the turntable.









The turntable was moved over by the center bearing foundation and flipped over today.

Crane arriving on site Tuesday.





Move and flip today.

Wow...well done, everybody!
Like witnessing a ship launch over at Bath Iron Works, where my old destroyer was built.
As usual, thanks Brendan for the great pics.
Oh, one question...will the 'table be complete, with track, when it is finally set ? TIA
Also...will you set the stem wall rail by measurement  before the 'table is set, or use its end wheels to exactly determine placement?

Nice work

Is the outer band overlaps riveted, bolted, or welded?
How is it held in place on the axles? Double nut? Tack weld?

Could not see.

The outermost ring is bolted together (it is in two halves).  The wheels are retained by a big cotter pin and a 1/4" thick washer.  There is a split ring just inside the outer ring to hold its position, even though it seems redundant, because the wheels are pulled in snug to the outer ring by adjusting the inside ends of the axles.  These are held in place by two nuts on either side of the middle ring.
