The stair is now laid on its back and (starting from the bottom step) the treads are laid in position, fitting perfectly without gaps. As each tread is positioned it is attached to the rear riser. Once all treads are positioned, the stair is laid on its side again and the end screws through the brackets are inserted. The fasteners attaching the tread to the top of the rise may be inserted as blind screws (using pocket holes in the risers) or blocks from the underside or simply using finished nails from the top.
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.
The biggest danger with AC powered stair lifts is that during a power failure, the stair lift will not function. Early versions of stair lifts were all AC powered. Trailing electrical cables presented tripping hazards, and the lifts moved in a jerky, start-stop manner due to the nature of the AC powered motor. At that time there wasn’t much choice because battery technology had not advanced as far as it has today. Today, DC powered stair lifts that only recharge from the household supply of electricity are the most popular lift chair designs. With DC powered stair lifts, if the power goes out, the battery can’t charge, but the lift will still be functional until the battery’s charge runs out. These models are quieter than AC models, too.
At the same time, it isn’t practical for someone else in the household to carry the disabled person up and down stairs. Ask the mother of a baby or toddler about carrying a 30 lb. child up a staircase several times a day. Now imagine carrying the equivalent of at least four toddlers up and down the stairs. It would be a daunting challenge even for a fit, strong adult to carry a lightweight adult up the stairs. There are a number of household devices and products that help senior citizens maintain their independence for as long as possible, from simple things like glucose meters to chairs that help them rise to a standing position, to personal alarm systems worn on a belt. Stair lifts are a big expense, but they can add immeasurably to the quality of life of the person who has trouble with stairs, and to the quality of life to a caregiver or other member of the household who had been tasked with helping the disabled person navigate the stairs.
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.
