Sheet aluminium can be cut without the need for a guillotine or tin-snips which tend to deform the metal.

With the aid of a straight-edge and a sharp knife “score” both sides of the aluminium sheet. This weakens the aluminium and creates a “fracture line”.

Place the “fracture-line” over the edge of a table and bend the overhang slightly downwards. Flip the sheet over and repeat. After a few “wiggles” the sheet will fracture along the cut-line leaving a clean break as shown in the above photos.

With care and patience full-size sheets of aluminium can be cut using this method. Create a long fracture-line then progressively bend the sheet from one end to to the other.

The metal-folder is made from two right-angle sections of metal. My folder is made from aluminium but “angle-iron” is okay.

The spacing between the two nuts and bolts determines the maximum width sheet that can be bent.

Prepare your work:

Mark where you want your bends.

Remove any unwanted corners.

Fold the aluminium:

Now slip the aluminium sheet between the two angle-s and roll the bender forwards while exerting downward body-weight pressure until the fold is 90 degrees.

Make a slot along one edge of your folder to accommodate the first bend.Position the first fold such that it will enter the slot when the bend is completed.

In 1812, British inventor Sir William Congreve patented a manual sprinkler system using perforated pipes along the ceiling. When someone noticed a fire, a valve outside the building could be opened to send water through the pipes.It was not until a short time later that, as a result of a large furniture factory that repeatedly burned down, Hiram Stevens Maxim was consulted on how to prevent a recurrence and invented the first automatic fire sprinkler. It would douse the areas that were on fire and report the fire to the fire station. Maxim was unable to sell the idea elsewhere, though when the patent expired, the idea was used.^{[7][8][clarification needed]}

Henry S. Parmalee of New Haven, Connecticut, created and installed the first automatic fire sprinkler system in 1874, using solder that melted in a fire to unplug holes in the otherwise sealed water pipes.He was the president of Mathusek Piano Works, and invented his sprinkler system in response to exorbitantly high insurance rates. Parmelee patented his idea and had great success with it in the U.S., calling his invention the “automatic fire extinguisher”. He then traveled to Europe to demonstrate his method to stop a building fire before total destruction.

Parmelee’s invention did not get as much attention as he had planned, as most people could not afford to install a sprinkler system. Once he realized this, he turned his efforts to educating insurance companies about his system. He explained that the sprinkler system would reduce the loss ratio, and thus save money for the insurance companies. He knew that he could never succeed in obtaining contracts from the business owners to install his system unless he could ensure for them a reasonable return in the form of reduced premiums.

In this connection, he was able to enlist the interest of two men, who both had connections in the insurance industry. The first of was Major Hesketh, a cotton spinner in a large business in Bolton who was also chairman of the Bolton Cotton Trades Mutual Insurance Company. The directors of this company and its secretary, Peter Kevan, took an interest in Parmelee’s early experiments. Hesketh got Parmelee his first order for sprinkler installations in the cotton spinning mills of John Stones & Company, at Astley Bridge, Bolton. This was followed soon afterwards by an order from the Alexandra Mills, owned by John Butler of the same town.

Although Parmelee got two sales through its efforts, the Bolton Cotton Trades Mutual Insurance Company was not a very big company outside of its local area. Parmelee needed a wider influence. He found this influence in James North Lane, the manager of the Mutual Fire Insurance Corporation of Manchester. This company was founded in 1870 by the Textile Manufacturers’ Associations of Lancashire and Yorkshire as a protest against high insurance rates. They had a policy of encouraging risk management and more particularly the use of the most up-to-date and scientific apparatus for extinguishing fires. Even though he put tremendous effort and time into educating the masses on his sprinkler system, by 1883 only about 10 factories were protected by the Parmelee sprinkler.

Back in the U.S., Frederick Grinnell, who was manufacturing the Parmelee sprinkler, designed the more effective Grinnell sprinkler. He increased sensitivity by removing the fusible joint from all contact with the water, and, by seating a valve in the center of a flexible diaphragm, he relieved the low-fusing soldered joint of the strain of water pressure. By this means, the valve seat was forced against the valve by the water pressure, producing a self-closing action. The greater the water pressure, the tighter the valve. The flexible diaphragm had a further and more important function. It caused the valve and its seat to move outwards simultaneously until the solder joint was completely severed. Grinnell got a patent for his version of the sprinkler system.He also took his invention to Europe, where it was a much bigger success than the Parmelee version. Eventually, the Parmelee system was withdrawn, opening the path for Grinnell and his invention.
