Forming Tools

However, we must not forget that hot liquid alloys requires incredible diligence and responsiveness. To melt the metals need a big temperature, as concluded from the fact mentioned above in the first all we should care about the heater to be simple to operate. This is primarily a home burner gas stove, , torch, furnace, etc. Robotics expert may help you with your research. The red-hot metal in a special container. Homemade bucket easily can be made from a segment of steel pipe. When the tin is small, it is better to make burning hot in the so-called melting substrates, which are made out of empty tin cans. Cast alloy standard link fishing k or make a fishing lure will not work without a. During the casting semolina for a copy you can take emulate tackle for fishing.

Model of the new items carved from wood, using all kinds of items manually labor, etc. Using the same tool produces patterns of materials. The starting materials are melted over medium heat and add a small piece of brown or yellow cream to boot (for contrast). As Build-Up of the hard type, you can use the ski ointments. According to the model of the special trains carried the so-called Plug-in form in which the future and cast parts. The most used material Gypsum is common substances to use forms in a home situation.

They are suitable for casting pieces of fusible materials. How to design a mass of plaster must be observed accurately. In a vessel of glass or aluminum is poured one on volume fraction of water. In the liquid is added in small pieces 2, 2.5 parts of gypsum, and soon the entire cast to connect with the liquid mixture quickly whisk until smetanoobrazioy mass. Make an array Pour into a cardboard box to the average level. Model dipped into the half. Plaster hardens in ten minutes. Convex and flat part of the billet lubricated with grease so-called separation – a saturated solution soap in the water. Then produce the second half of plaster and placed in a box. This compound dries day, after a time-box break, halves form and take out the workpiece. The finished model is put in a warm and giving dry. Complete drying of manufactured products (and this is a must!) Specializes simply call when you hit it with any object made of metal. Reusable templates potting should have increased strength.

Choosing A Camcorder

If you buy a video camera collectors, it is time to determine the types of cameras or camcorders. First and foremost, you need to decide on what the media is write your camera. By type of carriers can be divided into four types camcorder: MiniDV, dvd, hdd, Flash. MiniDV-camera records video on a mini-cassette. Ali Partovi has plenty of information regarding this issue. The resulting video has the lowest compression ratio and therefore the best quality.

True, and the video size will be large: one minute dv format takes approximately 200 mb. Captured video, you can throw at vashkompyuter by joining the IEEE-1394 (or Fire-Wire). dv format is well edited vmemi video editing programs, then the resulting film can be converted into any desired format from dvd to flv for the web. Such a camera – the best option for those who are going to make the captured video and installation to create their films. Other types of cells receive the video in MPEG-2 format, which has a larger compression ratio and, hence, its quality is inferior format dv.

This format is harder to edit in the editing programs, most simply do not perceive. But perhaps you do not want to edit video. Then DVD-camera for you is very convenient: DVD-ROM with your recording can be immediately viewed on a DVD-player. The disc has a size of 80 mm and it is located 1.4 gigabytes. This corresponds to about 25-35 minutes of video at best quality recording. Be careful: this camera does not like shocks and vibrations, as the record comes with a laser beam. HDD-camera records on a hard drive and Flash-camera – the flash card. Hard drives can have a capacity of 100 gb, which means that it puts a lot of hours recording even at maximum capacity. Flash cards come in different sizes, typically 4.10 gb. When buying a camera, you can choose. Of course, a small amount of the card is its drawback, but it has several advantages. This is the most miniature of all types of cameras (perhaps someone that is exactly what is necessary), it has no moving parts and, therefore, it is more reliable and consumes less energy. Video from these cameras can be easily transferred to the computer where it can be immediately watch or burn to dvd. It is now widely touted HD-cameras, which provide high-definition video. These cameras are more expensive and require special equipment for viewing (LCD or plasma wide screen, a special player). If you do not, you can not evaluate the quality of the video, and your purchase will not make sense. Now is your task – to determine what type of camera needed you.


From the filing date statements took place, at least six months, or even more. We first give permission only to build or purchase a transmitter, and only the flow of th proper work permits. These conditions only served to the emergence of new radiohuliganov. Historic for Radiohuliganstva became the 1980th year. Year, when instead of the promised Communism in Moscow held the Olympics.

Seeing the futility of repressive measures, the authorities decided to do a 'nod' – return to amateur radio band '160 meters', hoping thereby to get rid of radiohuliganstva. Hoped that the free operator in droves, race, rush to register their transmitters. This is evidenced by at least the fact that wireless operators to open new range has been allocated a special series of call, beginning at the ez. Feared that the call sign is not enough. But everything in life has turned out quite differently, as planned power! Some, of course, are gone, but the majority refused to 'fall in'. The reasons were at everyone and every decision taken on their own. In Russia, many were simply unwilling to change his call sign – the name ('Monday', 'Star' 'Serpentine') on the call – the number of (EZ one). Did not want to abandon the usual radiosvobody, reduce their power kilowatt transmitters allowed to 5 watts. Yes, and clearance processing remained the same tedious and time consuming business. In Ukraine, the villages, where every other lad had a minimum transmission console, and his grandfather, a machine gun in the hay and a bucket of bullets in a barrel, bacon, drove mobile radio monitoring points with radio range '160 m 'and the speakers' demonstrated' radio.
