You can build a staircase in a variety of styles, but one of the most attractive is the spiral staircase. It is also the ideal choice if space is limited.
Required Tools and Materials
Stairs
Welding tool
Wood
Hand saw
Pencil
Plumb bob
Tape measure
Blueprint of staircase
Railings
Wood glue
Start the stairs from a floor opening or to the left. Do not begin the stairs against a wall; it will make it hard to execute turns.
Step 2
Position the stairs and make certain you have enough space. The headroom on the stairs’ top must be 6 ft 6 in.
Step 3
Start measuring the staircase diameter and height. The diameter must have a 2 inch clearance minimum. This is from the floor and the walls (this will be for the handrail). Next, determine the tread height. You can figure out the width by the outside steps, not the one in the inside.
Step 4
Before you build a staircase, choose the wood. There are many options available, so pick the one that matches your needs.
Step 5
Saw all the stair risers. Set the width at four inches. Do not make it any wider because it will curl up. Get several wood pieces, as they will be required for making one riser. Alternate the wood grain as you put the pieces together.
Step 6
Sand the cut marks until they are smooth. Join the pieces together
using the wood glue.
Step 7
Saw the stair’s inner portion so you can reach the circular center. Make sure the stair is mounted before cutting. This will keep the radius intact.
Step 8
Mark where the center pole is at. Use a plumb bob to mount it. The pole length will be the same as the height floor to floor of the stairs.
Step 9
Use a welding tool to put the center pole and the bottom step together.
Step 10
Add the rest of the stairs. Join them to the center pole.
Step 11
Put the railing in place. There are railings made especially for spiral staircases. Install them according to the package instructions.
Tips and Warnings
You can get the riser height by dividing the diameter by 3.14. The result is the stairs’ circumference. Divide the figure by 16 treads. The result is the tread width outside.
As you build a staircase, make sure that the whole structure is level. In particular, assess the top landing before putting in the middle stairs. With spiral staircases, the alignment is critical.
