The standard winding tools are simply a pair of 18-inch lengths of mild steel rod, 1/2-inch diameter. Winding cones can have different socket sizes (such as 5/8 inch instead of 1/2 inch), so it is important to measure the socket and select a matching rod diameter. Also beware that poor-quality cones may have a sloppy fit to the winding bars, and a loose fit presents a severe hazard of slipping at the worst moment; anything more than about an inch or two of play at the handle end is too loose for safety. I bought a 3-foot length of zinc-plated 1/2-inch diameter steel rod from Home Depot for about $3, which conveniently cuts into two halves of just the right length (the store might even cut it for you if you ask). A steel supplier selling at commodity prices might charge about 50 cents or so for such a piece that weighs about 2 lbs. Drill rod would work if used in the annealed condition in which it is originally sold, but the added expense provides no benefit and the brittleness (if it had been hardened and not annealed) would worry me a bit. Rebar, threaded rod, screwdrivers, etc., are absolutely foolish as they will not fit the socket snugly. Aluminum rod is definitely too weak, and will bend under the torque that must be applied. Longer rods would make for more leverage but unwieldly swing; shorter rods make for uncontrollable swing. As we'll calculate below, the 18-inch standard tool length is an appropriate compromise. Note that you do not need 18 inches of ceiling clearance above the torsion shaft to use an 18-inch rod, since you need not swing the rods above horizontal when winding.
Garage remotes work by sending a coded signal via radio frequency to the garage door opener. If this code matches that of the opener, then the motor will operate and raise or lower the door. Older devices use a single coded switch, whereas newer systems utilise a rolling code that changes each time the remote is used, increasing the security of the door by offering billions of combinations.
Most styles, whether traditional or contemporary, feature panels, trim, and other detailing. Doors with true frame-and-panel construction tend to be sturdier than those with decorative detail that is merely glued or nailed on. Many styles have glass panels on the top row, which looks inviting from the street and brings daylight inside. You can also find roll-up doors with shatterproof glass or frosted plastic in all the panels, for a more modern look.
Carter door: Garage doors in Florida come with extra bracing on the back and are wind-loaded to protect against hurricanes. The average with is 350 lbs. but some can weigh as much as 800 lbs. It can cost up to $1,000 dollars to replace a steel two-car garage door and if it's made of wood it can cost you up to $5,000 dollars. Some customized doors can be as much as 20 - 30k.
A spring design manual, also called a rate book, gives tables that relate the torque constant ("rate") and maximum turns for springs of given wire size, diameter, and length. For example, a typical page in a rate book would show a table for a given wire size and inside diameter, the maximum inch-pounds (MIP) of torque available for a standard lifetime of 10,000 cycles in that size, the weight of the spring per linear inch, and the rates of the spring (as IPPT, inch-pounds per turn) for each of various lengths. From these figures one can calculate the lifting capacity, substitutions, conversions, and cycle life upgrades for a door of given weight and drum geometry. The weight-lifting capacity of a given spring is calculated based on its torque constant (IPPT, or inch-pounds per turn), which is the rotational version of the spring constant that characterizes the spring. The IPPT constant is found from tables giving IPPT for given spring dimensions (wire-size/diameter/length). The same tables may indicate the maximum number of turns for various expected lifetimes in cycles. The torque required to balance a given door can be calculated from the weight of the door times the moment arm of the drums (as we do below under "Calculating the Forces We Will Be Handling"). The ultimate torque of the spring in the fully-wound condition is the number of turns (when fully-wound) times the IPPT constant. Choosing a spring to balance the door then simply requires matching the ultimate torque of the spring to the balancing torque.

Recently another type of opener, known as the jackshaft opener, has become more popular. This style of opener was used frequently on commercial doors but in recent years has been adapted for residential use. This style of opener consists of a motor that attaches to the side of the torsion rod and moves the door up and down by simply spinning the rod. These openers need a few extra components to function safely for residential use. These include a cable tension monitor, to detect when a cable is broken, and a separate locking mechanism to lock the door when it is fully closed. These have the advantage that they free up ceiling space that an ordinary opener and rail would occupy. These also have the disadvantage that the door must have a torsion rod to attach the motor to.
Of course, the best garage door openers offer much more than weather protection. They are quick and convenient when leaving or returning home. They can secure what might otherwise be a weak point of home security. Some can even alert you at work if your garage doors aren't closed properly. The challenge you face is finding the right one – this isn’t a product you can simply try out and return until you find the best fit for your situation.
With over 300 independently moving parts, your garage door is a deceptively complex piece of equipment. To help prevent malfunctions and break-downs, it is a good idea to occasionally perform a garage door tune-up to keep all of these parts in good working order. A regular tune-up service by a Sears professional can prevent unexpected door problems and prolong the life of your existing equipment.
Insist on having any old parts returned to you, and have that noted on the written order before work begins. An honest and competent technician will not object to this. The evidence will establish whether you really needed the parts or not, and you can consult another opinion if you have any doubts. This tends to deter the parts-upsell scam, and protects you even if you know nothing about what you're buying while under the pressure of making a costly decision. If the old parts mysteriously "disappear", then you have reason to be suspicious.

Spring index lower limit: DASMA standard 102-2004 provides a lower limit of 6 for the spring index, which is symbol C in our formulas above (section 9.3). Other interesting items in this standard include an upper limit for how much the door sags when raised (no more than 1/120 of its width, section 9.2.1), that each of the two bottom brackets should sustain twice the door assembly's weight (section 9.2.2) for a total safety factor of about 4, and that the lift cables should provide a safety factor of 5.
