In the previous installment of How To Make Your Own Glass Bong, you picked out your liquor bottle and ordered the special diamond bit to cut the hole in it. Somewhere between then and now, you’ll have to empty that bottle, but I’ll leave that up to you :-) Right now, you have just a few things left to get, and luckily, they shouldn’t take long.
As much as I like to say “Support Your Local Head Shop”, I tried. They didn’t have anything I needed in stock, and if they did it would have cost $50 minimum just for the parts. So I dug around on the web, and found something even better: Free Glass!!!
That’s right, GlassblowersDirect sells all kinds of cool stuff, and one of their offers is a free (diffused!) downstem for new customers. You will need both a special hard-to-find downstem to fit the Bottaro bottle, as well as an actual bowl (to smoke out of!), so you can order both those things and only pay for one (plus shipping, which is incredibly quick). I don’t have any connection to them, just found them on the web and they seem to really have their act together, except for their slightly funky credit card ordering system (it’s secure through Paypal, they just haven’t hooked it to their website so they manually send you a link).
Here’s exactly what to order:
- 14mm Standard downstem, 3″ long (use this link for free downstem)
- 14mm Glass-on-glass clear bowl (use this link to add it to your cart)
If you want any other colors, customization, or accessories (nail domes for dabbers!), scroll around that page and choose them now, while you’re already paying for shipping (they use heavy-duty boxes and lots of bubble wrap). Remember, you need all 14mm stuff here.
If you’re using any other bottle than the Bottaro, you’ll have to measure it for the downstem. There are very detailed instructions on the GlassblowersDirect website, and these guys carry downstems in every quarter-inch increment between 3″ and 10″, so it’s a good place to know about in any case.
The magic in this case is a little rubber grommet that just happens to fit exactly into a 3/4″ hole and whose inside is just tight enough to grip the lower ground glass portion of the downstem securely. The rubber also shock-mounts the downstem while sealing the connection so air or smoke don’t escape. How much is this miracle? Just 75 cents at your local Ace Hardware!
Here is what you want for your grommet: ID 1/2″, OD 31/32″, groove 3/4″, stock 55059 (the link actually goes to Ace’s supplier and shows you what they look like, but any grommet will do as long as it’s the same groovy size :-). My local Ace carries these in their electrical department, but you should be able to find one of these in any decent hardware store.
Bottaro Bottle: $8.47
Downstem, bowl, and shipping: $18.00
Diamond-tipped hole cutter: $8.00
How To Do It
(This mandatory video covers steps 5 through 10 in detail — Watch It First!)
WARNING: Please read all steps carefully, and if possible print them out as a checklist, before starting work.
- Empty and wash out the bottle, clear your sink, and fill the bottle with warm (not hot) water. This will dampen vibration, support the bottle from the inside, and help the glass survive drilling on a molecular level. I forgot where I read that, but it worked for me :-)
- Put the diamond bit/hole saw into your battery-powered drill (do not use a plug-in drill for reasons that should be obvious shortly). Most typical household or commercial drills have two ranges; set yours to “high”. In any case, you’re looking for somewhere between 600 and 1000 rpm.
- Put on some safety equipment, since little pieces of glass will be flying around. At the very minimum, you should wear safety goggles or some sort of full eye protection. Protective gloves are nice too.
Drilling glass creates a lot of heat, so we’re going to be cooling the area by running water over it (this is why you must use a battery drill; AC power and water do not play well together). Find the spot you want to drill by placing the gasket on the glass just above the straw covering, and draw a circle around it with a Sharpie or similar. If you’re using one of the recommended liquor bottles, most of them have a dedicated round area that’s ideal and obvious for drilling. Simply pry off the plastic cover with a flat screwdriver first.
- Now, place the bottle in the sink so the mark is below the faucet, and run some warm water over the mark. It shouldn’t be either pouring down or barely trickling; you just want a steady stream of moving water flowing over your work area. This also helps carry away glass shards before they can fly around.
- With one hand, hold the bottle firmly by the neck (on the Bottaro, that’s the top twisty section :-). With the other, get your drill running at about 3/4 of maximum speed. When it’s spinning well, center the bit on the mark and hold it on the glass. Don’t push too hard; just keep a steady light pressure and let the spinning bit and weight of the drill do all the work. Make sure you’re drilling at a 90 degree angle to the glass so that the entire surface of the saw contacts the glass at the same time! It is possible to drill at an off-angle to the glass, but not recommended. This is why you need a bottle with a flattish spot and proper slant.
- It will only take about 2 or 3 minutes to go through the glass. Don’t rush it, but watch carefully. When you start seeing swirls in the water on the inside of the glass, you’re almost through, so ease up the pressure a little but keep the speed going.
- Once you cut through, use the bit to grind away any sharp edges you see, and then carefully pour the water out. Try to keep track of the piece of glass that used to be in the hole, so it doesn’t go down your drain and mess up your garbage disposal. Rinse the entire inside and outside of the bottle several times to get all the glass powder out before you start inhaling it!
- Break off any possible sharp pieces of glass with a pair of pliers, then put the grommet into the hole. Work the edges of the grommet around the glass.
- Put some water on the body of the downstem for lubrication, then slowly and carefully push and turn the downstem into the grommet (hopefully without popping the grommet out into the bottle itself).
- Now put the bowl into the downstem. You’ve reached 11 and you’re done! Congratulations!
This really isn’t hard to do. I never did it before and it came out fine both times, other than a bit of ground glass around one side when the bit slipped. In face, once you see how easy it is, you can set up a side business drilling bottles for your buddies and recoup the cost of all this experience :-)
Now you definitely deserve to smoke a bowl or two! I suggest putting all the tools and such away first though. If you’ve never used a bong before, make sure you pack a small bowl…you won’t believe how well it works!
If you don’t even know how to use a bong…that’s what Part 4 is all about!
