If you are looking for a creative way to enjoy your herb or tobacco, you might want to try making your own glass bong from a recycled glass bottle. A glass bong is a device that filters and cools the smoke from burning herb or tobacco through water, making it smoother and less harsh on your lungs. Glass bongs can be expensive to buy, but you can make one yourself with some basic tools and materials.
In this blog post, we will show you how to drill a hole in a glass bottle to make a glass bong. Drilling a hole in glass may sound intimidating, but it is actually quite easy if you follow the right steps and precautions. You will need:
- A glass bottle of any shape and size. You can use a wine bottle, a beer bottle, a soda bottle, or any other glass bottle you have lying around.
- A power drill with a small spear-tipped carbide or diamond bit. These are special bits that are designed to cut through glass without breaking it. You can find them at most hardware stores or online.
- A larger spear-tipped carbide or diamond bit that matches the diameter of the hole you want to make. This will be used to enlarge the starter hole made by the smaller bit.
- A piece of painter’s tape or masking tape.
- A felt-tip marker or ink pen.
- A folded towel or a soft pad to cushion the bottle.
- A bowl of water or a running faucet to cool the drill bit and the glass.
- Protective goggles, dust mask, and gloves to protect yourself from glass shards and dust.
- A 600-grit diamond file to smooth the edges of the hole.
- A metal or plastic tube that fits snugly into the hole. This will be the downstem of your bong, where you will insert the bowl that holds your herb or tobacco.
- A bowl that fits into the tube. You can use a metal or glass bowl from another bong or pipe, or you can make your own from a metal socket, a bottle cap, or anything else that can hold your herb or tobacco and has small holes for airflow.
- A rubber grommet, silicone sealant, or hot glue to seal the gap between the tube and the hole.
- Water to fill your bong.
Here are the steps to drill a hole in a glass bottle to make a glass bong:
- Mark the spot where you want to drill the hole with tape and marker. Tear off two strips of tape and cross them over your intended drilling site in an ‘X’ shape. Smooth both strips with your finger so that they are lying flat on the glass. Then, draw a dot at the center of the section where the two pieces of tape overlap with your marker. This dot will serve as a guide for your drill bit.
- Place the bottle on a folded towel or a soft pad. Lay the bottle flat against your makeshift pad with the taped side facing up. Make sure that the bottle is stable and secure, and that it won’t roll, slide, or shift while you are drilling.
- Fit your power drill with a small spear-tipped carbide or diamond bit. You will use this bit to make a starter hole, which you will then enlarge with a larger bit. Once you have selected your starter bit, slip the bottom of the shaft into the business end of your drill, pressing down on it forcefully to confirm that it is fully seated.
- Make a precise starter hole using low speed and moderate pressure. Align the pointed tip of the bit with the center of the crossed tape and hold the drill so that it forms a right angle with the surface of the glass. Squeeze the trigger of the drill lightly while pressing the bit straight into the bottle. Start drilling at a 45 degree angle and then gradually become perpendicular to the bottle. The drilling speed and pressure should be low and moderate, and reduced toward the end to avoid chipping. Keep a bowl of water or a running faucet nearby to cool the drill bit and the glass periodically. You can dip the bit into the water or run water over the bottle every few seconds. This will prevent overheating and cracking.
- Enlarge the hole with a larger spear-tipped carbide or diamond bit. Once you have made a small starter hole, switch to a larger bit that matches the diameter of the hole you want to make. Repeat the same drilling process as before, using low speed and moderate pressure, cooling the bit and the glass frequently, and reducing the force toward the end. Be careful not to apply too much pressure or drill too fast, as this could cause the glass to break.
- Smooth the edges of the hole with a 600-grit diamond file. After drilling, you will notice that the edges of the hole are rough and sharp. You will need to smooth them out to prevent cutting yourself or damaging your tube or bowl. To do this, use a 600-grit diamond file to gently sand away any burrs or chips on both sides of the hole. You can also use water to lubricate the file and make it easier to glide over the glass.
- Insert a tube into the hole and seal it with a grommet, sealant, or glue. Now that you have drilled and smoothed your hole, you can insert your downstem into it. The downstem is a metal or plastic tube that fits snugly into the hole and extends into the bottle. This is where you will attach your bowl that holds your herb or tobacco. You can use a tube from another bong or pipe, or you can make your own from a metal pen casing, a straw, or anything else that is hollow and sturdy. The tube should be long enough to reach about halfway down the bottle, but not touch the bottom.
