The first stringer can be laid on the floor using blocks and one end of each riser is attached to each bracket so that the risers are in a vertical position in relation to the stringer. The risers are attached to each bracket using blind screws through the holes in the brackets. The second stringer is then positioned over the opposite ends of the risers and attached. A clamp may be used to pull the stringers tight against the riser ends. This one step will eliminate up to 80% of the custom fitting normally required for conventional stairs.
In fact, the best time to add a stair lift system may be before it is actually a requirement. There are plenty of seniors who may not be disabled, but who experience intermittent conditions, such as an arthritic knee or hip, that make climbing stairs a challenge some of the time. Stair lifts can be installed in straight or curved staircases. Most models today run on rechargeable DC battery packs that hold a charge for around 8 to 10 trips up and down, depending on the length of the track and the weight of the person it is transporting. Some of these battery packs have chargers mounted next to the top or bottom of the lift track, while others are able to recharge from anywhere along the track. DC powered stair lifts are the preferred style today because they still work (for a while anyway) if the AC power to the household is cut. Many seniors, through no fault of their own, lose the ability to go up and down staircases with agility. And many of them have strong emotional ties to the house in which they live. A stair lift can make the difference between allowing a senior to have significant independence of daily living and having to making the difficult choice of selling a beloved home.
Starting with two parallel 2x6 stringer members, the adjustable brackets are first positioned using a spacing tool and then attached to each member with a single "pivot screw". For finished interior stairs, the stringers may be "paint" grade or "stain" grade but will have a tongue and grove or spline milled into the parallel mating surfaces so that once the brackets are adjusted, the mating surfaces will be pushed together to form a continuous, decorative, one piece knee wall stringer. The remaining screws are inserted and the end cuts are made. All the risers and treads are now square cut to the exact length using a chop saw. It is recommended that a stop is used for accuracy and efficiency. The treads are usually cut slightly shorter than the risers (1/64") for fit. For fast assembly it’s best to first pre- assemble the stair and then lift into position whenever circumstances permit.
Adjustable brackets are designed to be user friendly, fast, accurate and above all, strong. In fact, the brackets do most of the work. They automatically adjust to the exact rise and run and are approved as "adjustable joist hangers". This allows the risers to act like floor joists, carrying the load across the stair between the stringers which means only two stringers are required for stairs up to nine feet in width. Additionally, each stringer requires only three to four end cuts (only six to eight cuts per stair!)....significantly eliminating dozens of saw tooth cuts which are often required for conventional stringers.
The stair parts, then, is very important for all who uses it. We may hire professional stair makers or craftsmen to create the most perfect stairs that we wish from. An inexperienced stair maker can jeopardize the quality of the stairs and in turn, turn our dream homes into nightmare. We can use different materials in making the stair parts. First of all is wood. Wooden stairs create a very beautiful ambiance for any home. It also poses safety and practicality to its users since it is not slippery and is comparably softer than concrete. But, the type of wood is also very important. There are a lot of wood types and not all of them are strong. We must pick a high quality wood to fit the stairs and will last almost a lifetime.
