Got a new bit! Montana Brand Sintered 1/2inch Core-cutter, and man o man I will never buy a carbide tip again, this is 10x faster and it's done 5 bottles with no signs of slowing. Much much better.

So, I chipped this one, at the botom of the hole when trying to lengthen it for the angle. :( It's not too bad, and hardly leaks and only if you tilt it all the way against the grommet, but I definitely want to work to a better standard than that.

Still, it works great! I really like it, it looks pretty classy! I found the bottle at goodwill for $2, and it came with the string :)

Two more pictures!: One, Two
(Lowering degrees of enthusiasm, I know.)

The draw is good, about what you'd expect from a wine bottle. The top is thick so it rests against my mouth pretty well and seals comfortably.

The bowl and downstem are from a new shop, and I like them better. They're thicker glass and were the same price as the others I had. Though I think I found a couple of good resources for parts online!

All in all, solid piece, I could probably get a few bucks for it.

go for the diamond dust bits. I just recently got a set of them and they changed my life. Well maybe not quite like that but they're leaps and bounds better than the arrow head looking ones. I got a set of 5 off Amazon for a little more than $10 and could not be happier with how they performed. Couldn't find any at my local Home Depot. The only issue is that they only go up to half an inch in diameter and the smallest downstem i've found is a tad larger than that. There is a set of bits by the same brand for like 30 bucks and they go from the next size up to like an inch and a half diameter but i'm not sure if i'm ready to upgrade to those just yet. It would make drilling holes for standard down-stems exponentially easier, but I don't do that kind of thing with any regularity. To make the holes bigger I have used a conical grinding or sanding drill bit but make sure you use water to keep everything cool (especially the diamond dust bits) and be patient. I've cracked many a bottle pretty badly due to impatience and improperly cooling the bit.

Oh and the brand is Neiko

How to make a bong out of a Hennessy bottle:

1/5th bottles seem to work best. Get a bottle, wash it out, and set aside.

Go to a smoke shop and ask for a downstem and bowl piece. Ideally the down stem will be about 6” long. You can go longer/shorter depending on the angle your hole is made at.

Once you have your downstem, take a tape measure and measure the OSD of the glass. (Outside diameter. In my case the OSD was a hair over 1/2”, so I used a 5/8” drill bit)

Once you know the OSD of the downstem, you’ll need to go to the hardware store and get a drill bit that is at least 1mm larger than the OSD of your downstem. You need a special carbide (or diamond in some cases, ymmv depending on where you go to get the bit) drill bit that is intended for going through glass. They look a bit like this.

Drill your hole. ALWAYS WET DRILL GLASS. Always. Do it in your sink with the water running, and drill at about half-speed. It will take some time to get through the glass. The angle you hold your drill at will determine where and how the downstem sits in the bottle. About a 45 degree angle on the glass where I put my downstem works well.

Once the hole is made, rise the bottle out very well, and dry the outside. Put your downstem in the hole, and use some putty to make the air seal.

Pack a bowl, and enjoy 🙂

And here's my idea for one that I posted in the same thread. I'll leave the disclaimer cause it's funny.

Here's my crazy idea, cause imma be real I'm pretty fucked up right now, so let's go:

What you need, this can all be found online, in a hardware store, and at your house:

1. Mason jar
   
2. Cigarette lighter
   
3. 9v or 12v power supply
   
4. Ceramic crucible
   
5. A silicone pad for a dome/cap
   
6. A very long dab tool
   
7. Vinyl tubing
   
8. Latex tubing
   
9. Thick glue (like aquarium safe silicone caulking)
   
10. Thin glue (like super glue)
    
11. Brass hose barb (with a hose fitting size to match the inner diameter of your vinyl tubing).
    
    Steps:
    
    
12. To choose the vinyl tubing size, find some that fits in the joint of your bong. If you have a male joint, find tubing that fits over or in it; if you have a female joint, find tubing that fits inside it. There will be a size that works.
    
13. Now that you have your tubing, cut a short (3-4 inch), section of the vinyl tubing. Take the latex tubing, wrap it in tape of some sort to make its outer diameter the same as the inner diameter of the vinyl tubing. Add thin glue to the whole wrapping and press it into the vinyl tubing and let it dry. Optionally, add thick glue to the outside to ensure it won't leak.
    
14. If you don't have a hose barb, drill a hole in one side of the lid of the mason jar big enough for the vinyl tubing, then glue it in place with some of the thicker glue.
    If you have a hose barb, drill a hole in one side of the mason jar lid big enough to screw the hose barb into. Screw the hose barb into it, and attach the latex tubing to the other side (or wait to do that until you finished the rest of the project).
    
15. Get the cigarette lighter, extract just the coil, connect the two contacts to speaker wire leads, with enough stripped distance to not melt.
    
16. Drill a hole (or two) in the mason jar lid at the opposite side from the first hole for the wires and run them through the hole(s).
    
17. Glue down the ceramic crucible in the center inside of the mason jar.
    
18. Drill or cut as big of a hole as you can fit in the top of the jar to allow you to use the dab tool through it.
    
19. Run the wires for the cigarette lighter coil in through the lid and glue them in place so the coil rests right on the crucible, centered on it.
    
20. Test that the coil heats up to at least a dim red and doesn't melt its own wires.
    
21. With the wires and hose barb in place, cut (with scissors, a razor or tin snips) a piece of the silicone pad in this shape, to act as a cover (like a carb cap).
    
    That's it! In order to set it up, connect the latex tube to the hose barb if you haven't already (and if that's how you built yours), screw the mason jar lid on to the mason jar and dab away!
    
    In order to dab, get your wax on your dab tool and your silicone pad ready. Heat up the coil to red hot, then turn it off. Get ready with the dab and let it cool. As soon as it's just barely red, start to inhale and dab it. As soon as the dab tool is clean, cap it with the silicone pad and clear as normal.
    
    Make sure to take some pictures and tell me how it works!
    
    

    OPTIONAL:
    

    
    

    |10mm|14mm|18mm|
    

    --|:--|:--|:--|
    Male|LINK|LINK|LINK|
    Female|LINK|LINK|LINK|
    
    Glue the vinyl tubing into the female side with some of the thicker glue, instead of just sticking it onto/into your bong. Now the whole thing attaches with glass-on-glass action!

I got these diamond coated drill bits for like $10 that work like a charm. I drilled the initial hole which was too small, but because the bit is coated on the sides, you can expand it gradually. I love them and highly recommend them.

Then, there's how I was able to get it in at an angle. I made the hole and ellipse, not a circle, because I'm not using a grommet to seal it and the intersection of a cylinder and a plane at an angle i an ellipse. Then, because these drill bits can almost be used like dremel bits, I just went along the edges at the angle I wanted.

Okay quick PSA on drilling!

> http://www.amazon.com/Diamond-Tipped-Ceramic-Glass-Drill/dp/B00899COJY

I use this style of drill bit, which are avialable in 16 and 19mm. They work great because they don't have a central point of pressure like other types, and it has file etching on the side of the bit as well as the tip. when you drill, you submerge the piece in water and allow it to fill almost all the way. I like to wrap it in a water soaked rag to dampen vibration in the bottle and to shield my hand in case of shattering. certain surfaces are harder to drill on than others, such as rounded areas and or things with texture and design. It's simply a matter of getting that established nitch in the glass to do this I demobilize the piece as much as possible under water, and at a high drill speed give my desired spot a series of sharp taps. be as precise as possible while the bit establishes a nitch in the glass. once it gets going, drill at a medium to slow speed. when you see bubbles it means that you have begun to breach through. this is a good time to stop and check your whole. at minimal speed and pressure, drill through the remaining glass and remove the displaced piece of glass. next using the etching on the side of the bit, wear down the glass on the upper outer part of the whole, and then do the same to the lower inner part of the whole. this will allow your down stem to tilt downward more. Once you have your whole you need to fit a downstem in the most airtight fashion possible. I've used puddies, sealants, glues, and such but I'm personally a fan of a good old fashion rubber grommet. If your hole is good enough, you should be able to get a relatively air tight seal and your can avoid the risk of harmful chemicals. most head shops will carry a rubber grommet compatible for downstems and you can also find them online. Hope this was helpful, let me know if you have any more questions.

Use a glass drill bit like these

Make sure to use lots of water while you're drilling to keep it cool. If you keep it cool enough you can drill a nice clean hole.

If you're feeling handy you can use a tap and die set to put threads in it to put in a downstem that wont jiggle around as seen here

Edit: Don't tap the glass itself instead fit a piece of metal which is tapped. Fix the metal to the glass with super glue

Here's what I'm working on right now. Just ordered the pump actually.

"I had an idea today that I plan on making in the near future. You're welcome to use it or just parts of it.

I basically want to make an automatic waterfall bong. Something like this guy has (mine would be a little larger):
Demo of device:
http://www.youtube.com/embed/hrIAmgYTb5U
How he did it:
http://www.myvido1.com/QTHBXaYBjVxVWbKplYVBTP_tornado-bong-part-2-of-2-diy
but I want to integrate a small pump to get the water from the bottom to top chamber without having to turn the thing upside down. Not only does it allow you to be lazier, it allows you to build a sturdier base (so it won't get knocked over) that would otherwise be awkward to turn upside down and you don't have to worry about removing everything and plugging all the holes so nothing gets wet.

You could also get creative with the mouthpiece (don't use it leave it as the bowl like this guy). Maybe you could have it come out the top and swirl around in an adjacent ice bath.

Here is a pump I looked up earlier today:
http://www.amazon.com/Brushless-Submersible-Water-Ideal-cooling/dp/B0051HI3OM/ref=pd_sim_sg_1

If you do choose to build something like this, keep in mind that the water pump might need to have water in it initially to work (called priming the pump, I believe.) I was going to put the inlet of the pump near the bottom so that really wouldn't be an issue."

Yes. This style of bit also works.

http://www.amazon.com/Vermont-American-13310-4-Piece-Glass/dp/B000ETWIKM/ref=sr_1_3?s=hi&ie=UTF8&qid=1411526817&sr=1-3&keywords=glass+drill+bit

Looking through the options, I may get some of those diamond bits because they're a lot cheaper and come in a bigger range of sizes than my hometown hardware store. Fun side fact, the diamond bits work well for really thin, delicate pieces of glass.

Now that I’m home and have a minute to type, here’s how I made it:

-I used a step drill bit to cut two 3/4” holes in the mason jar lid. I kept the lid on the jar while drilling, held the jar with one hand and the drill with the other and it worked just fine (I marked the holes with a sharpie before drilling)

-I put in one hookah hose grommet and one “downstem grommet” (I get these from my local ace hardware. You just ask for a rubber grommet with an inner diameter of 1/2”, an outer diameter of 31/32”, and a 3/4” groove, I think the stock number is 55059) in the holes I drilled

-downstem time. I get them from a local smokeshop and I use just regular ol’ glass on glass downstems that work with a 14mm bowl. Before you fit it into the grommet, lube them both up with whatever cooking oil you have on hand (I use coconut oil). Getting the downstem in is the trickiest and scariest part to me but it goes relatively easy if you coat it in oil first

-all set, just put in a 14mm bowl in the downstem and a regular hookah hose in the hookah grommet and you’re good to go

Eta link for hookah grommet

That's 15mm, but whatever you're looking for. They're super cheap and effective.

Is there any particular reason you're using that glass? It looks like its already fractured, and may be jagged around the edges. From the looks of it, you may be better off using a brass bowlpiece, it wouldn't look too bad either. You can usually get them at headshops. That way you would just bore a hole slightly smaller then the bowl and screw it in, no adhesive required. Something like this is what im think of: https://www.amazon.com/TWO-Standard-Pipe-Bowls-BRASS/dp/B005MGU5TI
Anywho, good luck!

SILICONE SEALANT! its an ents best friend. waterproof so u can use it to repair bongs, nontoxic, and it tolerates heat well. so next time youre near a home deopt, pick up some DAP silicone sealant.

ok since no one here has said it yet, yes glass drill bits buuuut, it works waaay better if you get glass hole drill bits like this, http://www.amazon.com/Diamond-Tipped-Ceramic-Glass-Drill/dp/B00899COJY/ref=pd_sim_hi_5?ie=UTF8&refRID=0T0HMMZKXMAB7BVHZQ18 i actually bought the 14 mm but i will warn you now, 14mm glass downstems are only approximately 14mm, its closer to 14.6 or something so you give it like a millimeter so the rubber grommet can fit

Awesome! If it's your first time drilling into glass, practice a couple times on similar bottles first. Also make sure you're using a hole saw like this:

This pipe is fine. Haters are going to hate on anything that isn't glass, when there are a great many cheaper materials that work perfectly for pipe making. I have been using brass and brass pipe screens for years, and have had no problems with it. Brass fittings are lead free, and that's the only legitimate concern. Otherwise, the pipe may get a little hot, but it has never got too hot for me to not be able to touch the pipe. I do have one recommendation, though. Get one of these off of Amazon. It's a brass bowl that will screw into that pipe and then you'll have a real bowl. You will probably need some Brass Pipe Screens for it too, but none of this is expensive, and the brass bowl comes in a set of 2, so you can have two pipes. I've had the same pipe for over a year, and it still works perfectly. And the major advantage that brass has over glass: you can drop it without it shattering.

Use the egg-shaped bit. Hold the bottle under a small stream of cold water in your sink so that it is rolling over the spot your going to drill. Use a dremel on highest speed. Go slow and occasionally lift the bit off the glass while you're drilling. Once the bit is through the glass, use the sides of the spinning bit to sand away the glass and open the hole to to desired size. Bob's your uncle and you got a pipe. I'm currently in a pipe/bong making phase and this is my method.

I'm particularly proud of this one... Recycled Coca-Cola bottle 2-chamber glass bong https://imgur.com/gallery/ZHAt8

You can cut an array of different sized holes with these.
As for the gravity bong idea you should take a look at the product called the kinkajou. It's basically a mounted glass cutter for bottles. If you've got some carpentry skills you can make a brace with your glass cutting tool to cut bottles perfectly. Honestly if you get the bits all you'll need is a hole. Here's a link to a homemade bottle cutter you can make with your glass cutter: https://homemade-modern.com/ep01-diy-herb-garden/

Thanks man :D and I used a 1/2 inch diamond drill bit and the rubber grommet is also 1/2 inch that I got at my local hardware store. Diamond Drill Bit Link

diamond drill bits are useful for that, here

would any drill bit fit a standard drill? i don't have a personal drill, but i'm looking to buy a glass drill bit and borrow a friend's for a diy project with a huge belvedere bottle

I just ordered this and I'm finally gonna make my Vodka Spirit Bong into the bong it's been waiting to be transformed into. Probably gonna need a grommet and I'd like to find a way to make a perc although I'll probably buy a downstem with either slits or a tree perc

Something similar happened to one of my pieces. I used a 100% silicone sealant. It's waterproof and is safe at temperatures up to 400 F. Just make sure your piece is completely dry before applying it, and make sure you let it cure for at least 24 hours (it gives off fumes while drying, but does not once it's completely cured).

It’s on amazon too for $22

There are other kinds/brands of bits that can do the job, but I'm a fan of these.

i have a set thats a bit larger than this
main thing you have to look out for is if the bits you want will fit the chuck of the drill you are using

I start my hole with a Dremel and the round (ball) bit of a diamond Burr set found here: http://www.amazon.com/gp/product/B000MOI9G6/ref=oh_details_o07_s00_i00?ie=UTF8&psc=1

Buy one of these.

Attach it to a drill, and bore through the glass by letting the drill bit do all the work.
Run water on the drillbit while it's grinding through the glass, it prevent cracks from forming.
