OK, probably a dumb questions. Regardless, I'm asking. I tried to make two of them after work today. Two good sized glass bottles with really nice necks. I ruined them both. I've experience with wood working (see the camera that's my profile pic) not glass. For the first try I wrapped where I wanted the break to be with tape, grabbed just above the tape line put the bottle in a plastic bag and gave it a tap on the curb. I got some crazy jagged pieces. For the second try I did the tape almost the same way. But this time I scored the area where I wanted the break with my dremel, put it in a bag and gave it a tap on the curb. It was almost perfect but there was a crack up the side. Am I doing it wrong or do I just need more practice? I have one more bottle I can use and I don't really want to kill it. I know there's other ways.

Has anyone tried this: (1) score around the neck of a wine bottle. (2) Heat a container of water in the microwave oven until it is almost boiling. Put the neck of the wine bottle into the hot water. (3) Plunge the neck of the wine bottle into a container of ice water. (4) Alternate back and forth hot cold hot cold to expand the crack.
Here is a link that you can go to for cutting bottles with a tile saw: http://www.instructables.com/id/How-to-use-a-wet-tile-saw-to-cut-gl... Also look at the related article "Drinking Glasses from Wine Bottles" by fstedie on the same website. This article gives instructions on how to finish the cut glass edges.

I have found that I can get really good cuts using my Dremel tool on a slow speed using a diamond wheel (Lowes had a pack of them for around $10.00). You can actually cut all the way through the neck without cracking it. The cut at the base of the neck can be tapped to remove it after you made a good cut. If you try to cut the lip around the top of the bottle neck, you'll have to either cut it all the way through or cut really deep to remove it. I haven't tried using hot water yet. I have successfully cut and made 2 slides so far using this method without any problems. I'm sure a tile saw with a diamond blade would probably work even better. This method doesn't really take very long to do either.

Yep, that's the same disks I use. If a firm tap doesn't break the neck off, make the score a bit deeper and try again.

The standard "reinforced" cutting wheels work just fine. The non-reinforced ones (the cheap ones...) tend to flex and shatter. I've done this too, works pretty well. Just score around the neck in a nice clean circle and tap... The sharp edges can be removed by judicious use of the same wheel.
i personally only use the glass scoring method and have about an 85% success rate. pick up a glass "cutter" at your local hardware store, it's $5 or less. practice using it on whatever scraps you can. one tip from a professional glassman, hold the "cutter" like a pencil with your index finger on top of the indentation. keep an even pressure and don't double over your score. practice, practice, practice. i get the success rate i do because i've been "cutting" glass for ten years. once you get the score you want, hold the score over the candle flame as someone else on here mentioned then hold under cold water and kind of twist the top of the bottle away from the rest of it. once it snaps, you can sand the edges over with some 120 sand paper very carefully. it's all about the touch. oh, and hit your neighbors' recycling bins, they're a great place to pick up all kinds of cool wine and liquor bottles. stay away from beer bottles though, they're way too thin. best of luck!

I've tried a few methods:
scoring/heading/cracking:
- scoring with a glass cutting tool - didn't work well on round necks.
- scoring with a triangular file - this works much better. It's very important that your scored line be straight, that you don't have multiple start & stop overlapping areas, etc. So, it's a little tricky to do right on a bottle neck.
- I heat the scored neck over a candle flame until one side of the line is covered in soot, then hold under cold water. The neck breaks clean about 50% of the time, depending on how well I did the scoring.
- I like clean lines on the slide - so that means two cuts on a bottle neck to eliminate the top lip. That means about 4 bottles to get one good slide.
- it might be worthwhile to tap the inside of the neck with a small steel. That may break things more cleanly.
dremmel:
- One string willie gave better suggestions than I can, but let me mention a few points:
- first off - eye & respiratory protection are important
- secondly, you can use the side of the dremmel diamond blade to polish the edges pretty nicely. Afterwards, I typically just rub the slide edge on sand paper. That gets it looking pretty good.
- this is a pretty reliable method. But less fun than cutting & burning, and probably more expensive - since the dremmel diamond-coated blades are $15-20.
bottle-cutting jigs:
- i've never used them, but heard that they are great.
- I've tried creating some jigs to make it easier to work with a file, but so far it hasn't worked out well, but there's some light at the end of the tunnel.
Supplies:
- go to a cafe that serves wine. They can give you armfuls of free empty bottles. More than you'll ever use, unless you're picky and just want the neat blue-glass vodka bottles.
Break down and buy one of mine, C.B.Gitty is selling them on his site.
Holy Smokes!!! I just checked out cbgitty.com and checked on the slides. I wish I could afford them. Sometime in the future perhaps, but I don't get my overage check until August.

The best method I've used so far is to use a cutting disk on a dremel tool. .
Could you tell me what cutting disk you use? The only one I have was useless. The people at my hardware store are clueless ("A slide? Like at a playground?")
I get almost the same responses when I go to Menards asking about various projects. Dremel makes a diamond coated cutting wheel. They're kind of spendy but they're worth it.
