What is combination wrench used for?

The function of a wrench depends on what type of wrench it is. In general, small flat wrenches have two 'flats' that are sized to particular bolt or nut sizes.These wrenches are used to loosen or tighten nuts onto bolts. The crescent wrench is able to be adjusted to many sizes of nuts and are handy to have in a tight corner when you don't know the size. Ratchet wrenches are used to do up or loosen nuts quickly where movement may be restricted and you have to re-seat an ordinary wrench after each partial turn. Box wrenches have round heads, able to completely encompass the nut and are very useful where nuts are rusted or otherwise extremely tight. Pipe wrenches are usually larger jawed wrenches used to grip large pipe nuts and pipes themselves in plumbing work.

Are goodman furnaces any good?

Goodman backs their furnace with a 10 year parts and lifetime on heat exchanger warranty on most models. so they must be pretty confident about their product. The older entry level furnaces had a noisier burner than most but the new models are about the same with other makes. Some might say it is cheaply made but all entry level furnaces wether it is Trane,Carrier or Lennox are cheaply made.You just pay a lot more for those furnaces because of all the advertising. As far as reliability and performance, I don,t see any problems with the current models.Some will say that the sheet metal cabinet is not as thick as the other brands but that only matters if your going to sleep on top of it.The important part is that it is sized properly and installed by a reputable company.I have installed and service all these brands and I

don't see the advantage in installing the more expensive brand cause they all break and some were even DOA. I have had customers who insist in installing Carrier and Trane and get upset when their unit breaks down and can't believe that it did especially when the one year labor warranty is up.

These can usually cut holes in thin materials like plexiglass sheet, up to a foot in diameter. Forstner bits up to 6 or 8 inch can be used, these cut large, flat bottomed holes for installing clocks and other instruments.

Would you recommend guardian furnaces?

Guardian is the economy line of furnaces made by York. They are what they are - an economy line furnace. Don't confuse them as an equal to a Trane, Carrier or Lennox caliber of furnace. They are definitely built "cheaper" than those. However, I would put them as a step above Goodman, Tempstar, Whirlpool, and other bottom line furnaces. We sell YORK equipment and have been very pleased with the Guardian units. Not many intro line units can say they have a rating of 95.5% efficiency. Comparing the units to are other intro line (weatherking) and a friend of ours intro line (Goodman) they have a much heavier built cabinet and are much more versatile.

Is there is disc cleaning machine that's used to remove scratches from a disc?

How can you remove scratches from discs?

The best way to remove scratches from discs such as video games, DVD'S, CD'S is to use a product called Brasso. Brasso is very cheap to buy and works very well. Most of the time it removes the scratch straight away. But if it doesn't go straight away do it a few more times until the scratch finally disappears.

Below is the method how you use it:

  • Get a piece of cloth.
  • Put a small amount of Brasso on the cloth.
  • Rub the cloth in circular motion over the disc.

DO NOT USE TOOTHPASTE BECAUSE IT DOES NOT FIX THE DISC AND IT LEAVES SMUDGES ALL OVER THE DISC!

What is the length of a jump rope?

The sizing of jump ropes depends on how proficient a rope jumper is and the purpose of jumping ropes.

Proficient rope jumpers will utilize a shorter rope as they will only be jumping an inch or so off the ground. However, rope jumping for the purpose of performing tricks may require a little bit longer rope to allow for easier completion of the tricks.

A general rule of thumb for sizing is to stand on the middle of the rope and have the ends of the handles just reach your underarms.

If a rope is too long then an adjustment can be made. Adjustment of the length of a jump rope depends on the type of jump rope.

For cloth ropes simply cut the ends to length using sharp scissors and then tape the ends of the rope so that the cord does not unravel.

For PVC jump ropes, simply loop the cord near the handles. While this may not look pretty it is an effective way of shortening the rope without damaging the cord.

Some PVC jump ropes also have adjustable clips or clamps which will allow you to change the length of a jump rope easily and quickly.

When was the rope invented?

The earliest records of creating any type of rope date back to about 26000 BCE. It wasn't a discovery or recognized as an invention. But records have shown where humans twisted to braided multiple strands together to form a rope where apparently more strength was needed.
