Q:What type of motorcycle gloves are these or where can i find some like them?
First you need a tensioner. Best to use is the flat metal clippy part of a pen. This is going to go into the lock where the flat part of the key would go. Next you need a paper clip or a bobby pin or something thin to actually pick the lock with. Now first you need to know how a lock works there are pins in side that need to be pushed up, but only to a certain hight, before the lock will freely spin. Place your tensioner in the lock (its easiest if it is bent at a 90 degree angle first and place the small end in the lock) and turn it a bit the way that you would turn the key to open the lock. This will keep tension on the cylinder so you can feel when the pin clicks. Now with tension on it you will put your pick into the lock. Sometimes if you just rake it from back to front then front to back it will set all the pins if it is a cheap lock. If that dosent work you will want to start at the front and work to the back feeling each pin and pushing it up. You will feel when the pin is set. When all the pins are set in the right place the tensioner will turn and the lock will open. Best is to practice on a cheap lock for a while and then move to a Master Lock. It takes alot of practice.
Q:home window and door alarms?
copper is the way to go if doing it yourself. easy to cut and route without the hassel of threading. sweating is relatively easy if you clean and prep the joints properly. buy the coerrect tools and please use lead free solder with flux designed for such.
Q:Will you be campaigning?
To them their religious belief is just as important. Many faiths have clothing standards and follow them. The conflict comes when the particular faith is in the minority and the norm is far different. There isn't an easy solution. It may sound easy because you and others don't see it as a big deal but to them it is. Sikhs wear turban to cover their hair, orthodox Jews yarmulke. Many Christian churches require women to cover their heads when entering.
Q:Could i please get an explanation as to why NASCAR drivers are athletes?
Do not think of it as something like an iPad. It isn't. Think of it as a media consumption device, that you'll be reading books on, watching videos, listening to music playing some games on, and doing some light web surfing. It's wi-fi only. It does not have any cameras or microphones. You can load your own music on it. MP3s. Not sure about Apple's file format of music. And remember, it's only got a 7 screen, which means the screen really has only 1/2 the viewing area of an iPad. But in my opinion, it's definitely worth the $200 I spent on it.

Q:Can the sleeve type pipe joint be disassembled and assembled several times?
The European and American card sleeve pipe joint is a standard part, it can be disassembled and assembled many times, but it is better to check the sealing cone into the pipe, whether the inner component has the wrong face, the pipe is better to choose the new connection.
