How Big is your Elevator?

This afternoon, I cut the remaining support boards for the 2x8 section.  I will install those tomorrow as it got to be too late for drilling as people were sleeping in the house.

Later in the evening, I broke out the Walthers Prairie Coop Elevator kit.  I have been excited about this kit since it first came out.  It looks like many of the concrete elevators I have seen in Illinois.  This fits the bill perfectly.

I get the kit out and notice the size of the silos.  Wow!  This is tiny!  Surely, that must be half the silo and there are more pieces in the kit.  No.  Sadness.

Kit states it is 7 3/16" tall.  That may be with the additional dryer vents on top.  I measured from bottom of silo to top of head house at 6 13/16" (roughly 6 3/4").  I go grab a N Scale covered hopper for comparison.  Damn!  This is way too short!

I add the head house on top of the silo, but this still seems short.  I bust out the old calculator to determine this is 90 feet in N Scale.

I thought about purchasing another kit and doubling the height.  Silos and head house measure out to be 11 1/2".  This comes to 153' in N Scale.  That seems too large.  Performing a Google search, I find that these type grain elevators range in height from 100-130 ft typically.  90 feet seems to short.  I would rather have mine around 130 feet which is roughly 3" taller.  

I will have to ponder this.  Again, my goal is to recreate this.  I guess I need to break out the Walthers ADM silos and Walthers Famers Coop.  I have a feeling I will still need to add some height to this kit, but how much is the question.
