Sizing & Choosing Steps for Building a Spiral Staircase

Video Transcript

" Hi! This is Weldon Moon and on behalf of Expertvillage.com. I will show you another step in building the spiral staircase. Actually it is also a very important step that is determining the size of your step and I have taken 10 gauge material with diamond plates on the top with the tread on here and formed that to the size and you have got to decide the diameter of your spiral staircase. I normally go 6 feet 72 inches in diameter and then this is four and a half after that. I would go around a four inch pole, so you can see this is cut out to fit a four inch radius on a piece of pipe and then I have tapered it from two inches up to one inch to give it some strength and durability. We will weld the end to end but the important part here is that while you take a graph then you make like a pie and determine how wide you want to make these steps. A good distance here is about 16 inches which seems to work really well, anywhere between 15 and 18 inches seems to work well on the dimension out here, on this end of the step and so that is a good starting point is to do that. Then as you lay this out, you can determine where you are going to come onto your step and where you are going to come off the bottom of your spiral. If you are heading back into a corner and when you get the bottom and that is going to be a problem. So you have got to be very careful in laying it out, make sure that as you come down, your distances are right and the amount of pie that you are cutting off each time with each step will work. "
