After reading Sticks entry, I remember many years ago when I was a journey man Carpenter. We were building a house in the middle of a golf course outside Austin Texas. The owners had us divert from the architectural plans when ever they thought of something different. One thing we did was add a full basement under the house when none was allowed in the area. They just called it a wine cellar.
Well they wanted a half turn stairwell to the second floor. None of us on the crew had ever attempted one. I being young and not knowing when to shut my mouth, said, I would build one. I did my math and laid the thing out to make a half turn. I made a 36 X 6 1/4 inch box out of 2x6 and tied it to a 36 x 13 1/4 inch box with a slight turn with more 2x6 stringers, the next one was 20 1/4 x 36 and so forth , up it went. By the time I got to the 6th step, I was making some pretty big boxes out of 2x6 and tying them together with 2x6. I thought it was going pretty good. Until the owners came out to see what was using all this 2x6. The thing looked pretty rough but it was solid as heck. It took hours for the real stairs crew to tear it out to build a real spiral staircase.
They let me go a few days later, no longer need my services.
I have always wanted to try to build another one, but no one has ask me. Maybe I will build one in my shop to get to the lumber stored in the attic. Hmmmm??
