Glue guns can be purchased in low temperature and high temperature hot-melt versions. Low temperature units heat up to about 120º C and are more suitable where a high temperature is not wanted. High-temperature glue guns} heat up to about 195°C and give a stronger bond. Also available are dual glue guns which feature a switch so that both low and high temperatures can be used for different applications.

For industrial applications, there are a comprehensive range of heavy duty glue guns available which are designed to optimise production efficiency. These units range from high output compressed air industrial glue guns to variable temperature units.

Glue sticks are buyable in several different diameters for different varieties and sizes of glue guns. The most common size has a diameter of 11mm. Glue sticks are also available in various lengths, from about 10cm upwards. However, the majority of glue guns will accommodate glue sticks of any length. Hot melt and low temperature glue sticks are available for the different types of glue gun. Hot melt adhesives do not contain any solvents or water. They bond when they drop in temperature and this means that they can set quickly.

For industrial needs, different types of glue sticks are available for specialist uses. The most common diameters are 12 and 43mm. For domestic use, there are only a few types of glue sticks that are available. Glue sticks have different open times, which is the time taken to form a bond. This varies from a couple of seconds to a few minutes.

Glue guns should be switched on several minutes before they are used so that the heating element and glue stick can warm up. As the glue stick gets hot it melts and then it can be used to bond different materials together. Care should be taken when using hot glue guns as hot glue can be hazardous.

The purpose of square foot gardening is to harvest the most produce possible from the space available, by growing small quantities over a longer time. This is also achieved by reducing the space between plants. To ensure you understand your garden and learn about plants you should keep a square foot garden diary to have a log of your failures and successes to improve your results.

The practice of square foot gardening is not just for those with small back yards; rather square foot gardens allows you to concentrate your work effort to create an ideal plant environment, to give better natural yields.

The are many people who like the idea of digging for victory. They enjoy the sight of long, straight rows in their gardens and the hard labour that goes with digging and hoeing the land, whilst others prefer machine cultivation.

It’s hard to believe that Social Security has been with us for over sixty years - before there was even such as thing as a 401 retirement plan. The first Social Security check went out in the mail in 1940 even though President Roosevelt had signed the Social Security Act into law, five years earlier. Since then, many American seniors have been thankful to receive that monthly financial safety net as they entered their retirement years.

In the original incarnation of the bill, Social Security benefits were only to be paid to the primary worker. But, before the bill went live, additional benefits for the spouse and children were added.

Quite a few folks erroneously think that the Social Security system is equivalent to an investment annuity, in which you send money to the government. They will then invest it and give you the resulting income in monthly payments for the rest of your life. In fact, however, the system is closer to a government welfare program. The collection of payroll taxes , which finances the Social Security program, is managed under the authorization of the Federal Insurance Contributions Act, better known as FICA. FICA is like the enforcement arm of the system. It ensures that every worker “contributes” his or her fair share to the government pool.

Each new generation of workers is responsible for taking care of the previous generation’s retirees. The amount of money you eventually get back from the government has only a tenuous relationship to the amount of money that was deducted from your check over the years. Since it’s inception, the system has collected from contributors and paid out over nine trillion dollars to recipients.
