14 best mechanical power springs
Mechanical power springs, also known as clock springs or mainsprings, are mechanical components used in various engineering and transportation applications. These springs store mechanical energy when wound up and release it gradually as they unwind. They are commonly found in devices where controlled energy release or torque is required, such as in clock mechanisms, spring-driven toys, and even some automotive applications.
Here are some key points about mechanical power springs:
Function: Mechanical power springs store energy by winding them up, and they release this energy as they unwind.This controlled energy release can be used to drive various mechanical systems.
Construction: Power springs are typically made from coiled strips of steel or other suitable materials. They are designed to have a specific geometry that allows them to store and release energy efficiently.
Applications:
Clocks and Watches: Power springs are commonly used in the mainspring of mechanical clocks and watches. When wound, the mainspring stores energy and gradually releases it to power the timekeeping mechanism.
Toys: Spring-driven toys, such as wind-up cars or jumping animals, use power springs to provide motion and entertainment.
Automotive: Some older automotive designs used power springs in various components, like automatic transmission mechanisms, to control certain functions.
Safety Devices: Power springs can be used in safety devices like seatbelt retractors, where controlled tension and energy release are crucial for safety.
Winding Mechanism: Winding up a power spring typically involves using a winding key or a winding mechanism. When the spring is wound, potential energy is stored in the coil, which can then be released gradually to perform work.
Tension and Torque: The tension or torque generated by a power spring depends on various factors, including the spring's geometry, the material it's made from, and the degree to which it is wound.
Advantages: Power springs are known for their ability to store a significant amount of energy in a compact space. They are reliable and have a long operational life when properly maintained.
Maintenance: Power springs require periodic maintenance to ensure they function correctly. Over time, they may lose their elasticity and need to be replaced or rewound.
In engineering and transportation, power springs play a crucial role in providing controlled and reliable mechanical power in a wide range of applications. They are valued for their ability to store energy efficiently and release it when needed, making them a versatile component in various mechanical systems.

User questions & answers
Question: | Anyone have an issue with this not turning the fan off? Dial just keeps going past |
Answer: | I ordered two of them, and neither one would turn off or count down by itself, the dial just stayed wherever I turned it to. I returned them, and got electronic timers instead. The mechanical spring/countdown mechanism on these junky things is absurdly fragile. |
Question: | Spring powers dry contact 10amp rated switch closed for selected time. no neutral means no v drop so no power used. why wouldn't it work for 12vdc |
Answer: | Hello ART005, thank you for your question. The dry contact was not designed or evaluated for use in DC circuits or not evaluated for use in 12V DC circuits. The device should only be used within the published ratings. |
Question: | Can i make this normally closed and have the circut open when wound |
Answer: | That is exactly how it works. Closed always, wind the switch and it is on for up to an hour, bsed on how far you wind the switch. |
Question: | Can you use this on 12V DC |
Answer: | No, it is rated @ 125v AC. 12V DC will probably not run the winding circuit. But for only $9, give it a try. |

Introduction
Welding is a practical skill that is challenging, rewarding, and also great fun. We encounter welded items throughout our daily lives and activities—they are practically infinite. The appliances in our home, the railing on your porch or stairs, our automobiles, the bridges and infrastructure we drive on, the structure of the buildings we work in, and even our computers. Welding makes everyday tasks more manageable. Welding can also bring joy to a craftsman making items for use in the shop, home decor, and outdoor living and decor.
Basics
The costs involved in setting up a well-equipped home welding shop are comparable to setting up a well-equipped woodworking shop. A knowledgeable welder with the proper equipment has a great advantage, because the projects and repairs he or she can accomplish are too numerous to count. The availability of numerous inexpensive materials is also key to being creative. From basic repairs, to building your own shop tools and work stations, to creating items you can sell—the possibilities with welding are only limited by your imagination and experience. Always striving to learn and improve your craft lets you experience the “wow” factor when others see and admire your work.
Techniques
In this chapter we will discuss the basic cutting and welding processes. These techniques are the foundation of your skill set as a welder—skills you will use again and again, regardless of the type of welding you pursue. This chapter also provides basic directions and step-by-step photos that illustrate major welding and cutting processes. You will find quick reference charts that describe electrode selection and filler wire choices, metal types and weldability, and joint design and weld types.

Coat Rack
This chic coat rack has a modern artistic flair due to the unique circular patterns. But the basic design has unlimited potential. You can customize this rack for any part of your life—the front entryway, the garage, the gardening shed, and the cabin may all have different styles. Simply replace the spirals with a punched tin pattern, decorative frieze, or dragonfly, moose, or bear stampings. The rack is sized to mount on studs spaced 16 inches apart. If you like the spirals but want more contrast, use copper or brass 14-gauge wire and leave the entire piece unpainted—but be sure to braze the spirals into place, instead of welding them.
Part | Name | Dimensions | Quantity
(A) | Hooks | 3⁄16" square bar × 111 ⁄2" | 5 (B) | Mounting | washers 3⁄4" | 2 (C) | Balls | 1 ⁄2" | 5 (D) | Crossbars | 3⁄16" square bar × 16" | 2 (E) | Circles | 1 ⁄8" square rod × 24" | 4 (F) | Mini-spirals | 18-gauge wire | 6 (G) | Spirals | 18-gauge wire | 2.
Make The Hooks & Frame
(Step 1.) Cut the hooks (A) to length. (Step 2.) Clamp one end of each hook to a 2"-diameter pipe with a vise-style pliers. Bend the bar a half turn around the pipe to create each hook. (Step 3.) Weld each of the two mounting washers (B) to the top of two separate hooks. Weld a ball (C) to the end of each hook. (Step 4.) Cut the crossbars (D) to length. Mark the crossbars at 4", 8", and 12". (Step 5.) Align the two hooks that have the mounting washers flush with the crossbar ends. Tack weld in place. Place the second crossbar 4" from the top crossbar and tack weld in place. Check that the angle between the crossbars and hooks is 90°, and finish the welds. (Step 6.) Center a hook under the two crossbars at the 12" mark lining the top of the hook flush with the top crossbar. Check that the angle between the hook and crossbars is 90°, and weld into place. (Step 7.) Weld the remaining two hooks to the crossbars at 4" and 8".
Make The Circles & Spirals
(Step 1.) Cut the circles (E) to length. (Step 2.) Clamp one end of a circle blank to a 4" pipe using a vise-style pliers. Bend the rod around the pipe one and a half turns to form a circle. Repeat to form the remaining circles. (Step 3.) Create the spirals (F) and mini-spirals (G) using a needlenose pliers. Wrap the wire around the end of the pliers to create a circle. Remove the circle from the pliers and grip it in the pliers. Wrap the wire around the circle until the desired size spiral has been formed.
Assemble The Decorative Features
(Step 1.) Place a circle in the space between the first two hooks starting either on the far left or far right end. Squeeze or expand the circle to fit into the space and cut off any extra length. Weld the circle ends together and weld the circle to the two hooks. (Step 2.) Repeat step 2 with the remaining circles. (Step 3.) Arrange three mini-spirals inside the second and fourth circles. Weld them to each other and to the circle at contact points. (Step 4.) Place the large spirals between the remaining hooks and weld in place. (Step 5.) Wire brush or sandblast the coat hanger. Apply the desired finish.
