Medieval Siege Weaponry: Castle Walls Beware

Medieval siege weaponry was required in any self-respecting war leader's arsenal in a time when castles with thick defense walls were common and cities surrounded by large, fortified walls were not out of place. With warfare commonplace, it's little wonder the variety of medieval siege weaponry is great. After all, what was an attacking band of raiders to do when presented with an "impenetrable" castle wall? Break it down, of course, using one of the many designs of medieval siege weaponry available. One of the earliest examples of medieval siege weaponry appeared around the 300s AD when the ballista was created. The ballista wasn't the most accurate in the line of medieval siege weaponry, but it could launch a wave of spears further than human arms could muster.

Created using two wooden arms, tightly wound ropes and a cord to assist in the hurling of deadly projectiles, this example of medieval siege weaponry used torsion force to launch objects. The Romans added their own model to the list of medieval siege weaponry when they created the mangonel. This model called for only one wooden arm. The mangonel, however, had somewhat of a design flaw in that in called for a wooden barrier to be constructed. A ferocious example of medieval siege weaponry came online in the 12th century with the deploying of the trebuchet.

The trebuchet used a long wooden arm rested on a pivot point, which acted as a large lever. A projectile was placed on one end and warriors in this earlier version of the trebuchet pulled on ropes attached to the other end to essentially swing the arm around and hurl the stone. As far as examples of commonly used medieval siege weaponry are concerned, however, catapults and their sister designs do not hold the only billing. Other tools were readily available to would-be conquerors. The battering ram, for example, has been used through the ages and still is employed by modern law enforcement.

This version of medieval siege weaponry involved the creation of a very heavy weight placed on wheels used to help batter fortifications. It was usually made of a large tree trunk, and sometimes rather than wheels, a group of warriors or a sling frame helped provide the force necessary to crack fortifications using this simple, yet effective, example of medieval siege weaponry. Other items in the medieval siege weaponry arsenal included ladders and not-so-simple siege towers. Ladders were employed simply to scale castle walls. If the defenses stopped this measure, siege towers might be built to allow archers clear lines of attack to enemies standing on castle walls.

As far as medieval siege weaponry is concerned, siege towers were somewhat difficult due to their cumbersome nature. Towers were rectangular and often constructed on four wheels. They were as tall as the castle walls or taller and were designed to protectarchers, warriors and ladders as an army advanced. The downfall of siege towers in the long line of medieval siege weaponry, however, was their size and the propensity of the defending army to hurl projectiles at them. The examples of medieval siege weaponry vary greatly, but whatever their design they all had one purpose ? to deliver an army to victory.

Boat Ladders

A boat ladder is an essential accessory for boats. They help in climbing in and out of the boats. Boat ladders can assist in climbing in the boat from two ways; one from the deck mount and two from the side. They come in a variety of models ranging from single step to five steps. The height of the boat helps in deciding the number of steps you need.

They are mostly manufactured in a combination of aluminum, stainless steel, vinyl and plastic parts. Boat ladders have two hooks at the top to fit on the boat's side for support.
The width of your boat side should determine the size of the boat ladder hook. Most boat ladders come in folding type models with unbreakable rungs and do not sink in the water.

Shingling a Roof

Shingling or roofing a house is a major undertaking for a homeowner and extreme caution is required. This said, a Do-It-Yourselfer homeowner can shingle or roof their own home with a little knowledge and the right tools.

Required Tools

In order to roof a house properly and safely the following tools are needed: Ladders, Roof Jacks, Hammer, Carpenters Knife, Chalk Line, and preferably a compressor or nail gun.

Estimating Materials

Typically the roof is measured in squares, where a "square" represents 100 square feet. There are eighty shingles in one square. However, when you go to your local home improvement store shingles are usually sold in bundles. Usually three bundles equal one square, however this can vary slightly pending the shingle style.

Measure the area of your roof (length x width) and divide by 100 to get the number of squares required.

Then multiply this number by three to get...

HDTV EYE CANDY! Which wins? 1080i vs 720p. And what about 1080p?

The latest great thing in home theater displays is the emergence of 1080p resolution displays. p stands for progressive, which means the screen fills all at once at 1/60th of a second, versus i for interlaced, which means every other line, then the other half of the full picture, each field displaying at 1/30th of a second.

At this time, there is no source for broadcast 1080p programming. Instead, we have 1080i: two interlaced fields make a frame, at 1/30th...
