A dab rig consists of a stainless steel cone holding a single glass, which is placed inside a reservoir of butane gas. The inside of the "dab" must be lined with paper towels or some other absorbent substance, as it is very easy to blow up a "dab" or cause an explosion if the butane fuel is present to burn. There are no specific regulations on how to build a dab rig, but it does help to keep the size of the "dab" small and tightly controlled. Dab rigs or oil rigs often require flash-pressure, so make sure you use a professional grade torch. A good dab rig is usually the case of a long glass tube, attached to a banger or nail, utilized for dabbing, usually located in the lower area of an oil drum typically located on a bong.
To begin, you will need to secure the top of the water pipe in place, this is achieved by nailing or screwing a tee onto the pipe, through the water pipe with a nut hook or similar tool. Once this has been done, you should insert the stainless steel cone into the upper part of the banger. The stainless steel, in conjunction with the tapered bottom, will keep the glass from rolling or tipping, while allowing the tube to fill the reservoir. If you are using a nail, make sure that the nailing point is right where the cutout is located. If not, the result can be disastrous. Also get amazing custom dab rigs from this site.
Once the tube is secured, you should apply a small amount of residual oil into the "dab". This is done by inserting the cotton swab through the banger and into the reservoir. When you find that the tube is full, close the banger and shake off the excess residual oil from the bottom of the bottle. You may also want to take another pass with the swab through the pipe in order to smooth out any bubbles.
Once the initial dabbing has been completed, you can begin to inhale. To do this, simply hold the torch to the end of the pipe and inhale the smoke. By doing this, you will ensure that you are inhaling the purest form of oxygen. However, it is important to note that this method requires constant torch holding for about one minute after each inhalation, in order to prevent excess oil from building up.
A good way to enjoy the benefits of this apparatus without having to hold the torch is by utilizing the vaporize technique. This is a very popular method, and it should be easy to figure out. Basically, all that you have to do is set up the vaporize area, with the Dab Rig included, next to the glass or other viewing area. Next, position yourself so that your face is right up against the glass and then close the Dab Rig's eye tight. Then, open the top half of the tube, making sure that both the tube and the holder are within the reach of the goggles. Position your face right up against the glass, close your eyes and allow the Dab Rig to do its job. View here for more details about dab rigs.
One of the advantages of using the dab rig for this process is that you can position your face right up against the glass without needing to actually hold it there. If you want, however, you can also position yourself over the area where the steam is released and watch the smoke move upwards into the air. Some people find this to be much more visually appealing. Other people find that this makes it difficult to see the pattern as the smoke goes upwards, and they prefer to keep their face away from the area where the oil gets cooked off. No matter which way you prefer to view the results, you can generally expect to see a nice smooth white cloud move upwards, and often you may even get a rainbow effect when the light hits the butane gas in the reservoir.
