Another Shack for the Lime Kiln

Although several photos of pulp mill lime kilns had a rather open structure for the higher end, without really knowing what to put in the open frame, the idea to enclose the high end arose -- before and after:

     

The rusted metal sheets came from a Clever Bros "kit":  

The top in this case is a gabled roof and only three sides were enclosed.  I did use colored pencils to darken the insides a bit, but maybe will still try to find what goes inside.  

So might still use an open frame structure but only if the "innards" can be understood.  In the meantime, I like the more "finished" look.
