Q:hey guys ive been running thru various sites trying to make a name for my band jus have pieces at the moment like jus an idea to start from something like The ______ or add some words like monastery / cathedral that sounds cool or cidade de deus :p ( what would city of angel or some cool name be in that language? plz suggest some cool name in english or something that sound cool or gimme some link i can use to grab some nice names, thanks :): Hmmm. okorder that has thousands of them. There's also a random band name generator too, if you get desperate. Oh, and a good idea is to click the random article link on Wikipedia. Anyway, I hope you find a name for your band. I'm pretty much in the exact same situation right now, but I have a few choices.

Q:I have an excavator, a dumptruck, and a backhoe. I've only really used these to dig my pond and move firewood. Are there any benefits to owning them other then personal use, like possible job oppertunities or business ideas? Thanks: The benefit is that you can write off a lot of expenses. You are still out the money. But, save a lot on taxes. The best benefit is that you are friends with the boss. HA!

Q:Im looking for new tires for my 1987 Suzuki 250 QuadRunner 4x4. I came across some a tire called the Duro Excavator HF274. It is exactly the kind of tire that I want because it is good for mud and snow. It is a 4ply tire. But what im not sure about is if it might be to heavy for my quad and if the treads are going to be to agressive for the transmission on my quad becasue it is only a 250cc.: It looks like a good tire to me. The four ply is a plus, because you don't have to worry as much about puncturing a tire.

Q:Stumps, 3ft diameter rocks, plenty of large pines, etc. Cleared, leveled and made ready to turn into a yard... any idea? Heard somewhere around $8,000 an acre.... Any excavators or landscape construction or loggers/ landowners inputs would be appreciated.: contact ur real estate agent

Q:I was wondering if there is a huge difference in damage and speed. I need an idea on which direction I want to go. Dual or Rifle.: No, there is no huge difference. Use Dual. Greetings The Freak

Q:Excavator first originated in that country?: Excavators were originally manual, and have been invented for more than one hundred and thirty years. They have been driven by steam, electric power, and internal combustion engines. After 1940s, hydraulic technology was applied to excavators. In 1950s, a crawler hydraulic excavator was developed.

Q:im 35, i have blue card ,green card,first aid,confined space,working at heights,excavator and forklift tickets: Move to the Rocky Mountain area. There's a bunch of open pit coal mines out here looking for miners. In fact Wyoming is the top coal producer in the US right now. If you can pass the drug test and the physical, you'll be hired especially with your credentials.

Q:My 5yr old wants an excavator cake for his birthday,i enjoy baking but cannot find a recipe anywhere,that shows you how to make one, and how to make the icing yellow,can anyone help please,thanks.: Assembled from a pound cake and Twinkies, this no-bake treat will please the crew at a celebration with a truck or vehicle theme, or at our construction party. Ingredients 9 1/2-by 4-inch pound cake 1 1/2 cups yellow frosting 1/2 cup light-brown frosting (white and chocolate mixed together) Chocolate decorators' frosting 4 mini chocolate-covered doughnuts Blue and green MM's candies Red and yellow gumdrops 4 Twix 2 Twinkies 4 (8-inch) wooden skewers, trimmed into two 4K-inch and two 6-inch pieces 4 yellow Twizzlers Rainbow Twists, cut to the same size as the skewers 12 chocolate cookies (we used Oreo cookies) X Instructions Cut a 2 1/2-inch-long section from one end of the cake. Frost the section's cut end and place it on top of the cake for the cab, as shown. Cover the entire cake with yellow frosting, saving about 1/3 cup for the loader and bucket. Spoon the light-brown frosting into a resealable sandwich bag, snip off a corner, and pipe a window onto each side of the cab. Outline the windows with chocolate decorators' frosting, then press the doughnut tires in place. Add MM's and gumdrops for lights and hubcaps. Use Twix to add a smokestack and loader arms. Frost one of the Twinkies yellow, set it on the loader arms, and add chocolate decorators' frosting details. Cut a 2-inch section from the other Twinkie, place it behind the truck for the bucket, and frost it yellow. Add pieces of yellow gumdrop for teeth. Slide the skewers inside the Twizzlers. Press them into the cake and bucket as shown, using dabs of chocolate decorators' frosting to join them. With a rolling pin or food processor, crush the chocolate cookies into dirt and sprinkle it around the cake. Serves 8.

Q:your opinion: There are many instances where archaeology has confirmed the bible. Note I am not suggesting that archaeology has proven God's existence merely that the places and historical battles are with merit. The writer of the book of Luke has been considered a first class historian. At one time they questioned some of his territorial boundary suggestions only to later have them verified by new findings. They have also found the place where Pilate ruled and the pool of siloam that was mentioned in the gospel. Many many findings have confirmed these places which stands to reason. People would Know if they made up a bunch of places and people that they never existed. Now the book of Mormon can't prove any of the places mentioned in them ever existed and is filled with historical inaccuracies such as claiming that there were elephants oxen horses and other items at a period in time before they were known in the America's. These animals and items weren't introduced into this hemisphere until the Europeans started coming over.
