Went and bought a glass cutter and planned on using the boiling water / cold water technique to pop the ends off of some beer bottles. First bottle, the cutter seemed to score a line but of course it was crooked so I tried again. This time the cutter would not score the bottle. I turned the blade to another one and still nothing. Is there a secret to using a glass cutter? I tried scoring it with a cutting wheel on my Dremel. This seemed to score it but when I tried the boiling water cold water treatment, no luck.

  • I had mixed results with the glass cutter, boiling water/ice water methods as well.  They seemed to take forever as well.

    Harbor Freight has a diamond cutting wheel set with an angled one.  Chucked in my droll press, it cuts a wedge into the bottle neck that breaks it off pretty well in about 10 seconds..  A little sanding to take the sharp edge off & done.  Works for me.

  • The sidewalk rub is OK for the outside edge, but your finger goes inside so emery cloth or a grinder wheel are in order there.

  • I've tried a number of times but could never get what I wanted so I ordered a Diamond Bottlenecks custom made for my digit (ring sized) - tapered the way I wanted and the color I wanted.   I would cry a river if I lost or broke it - and then I would immediately trick my wife into letting me order another one.  I love it.

  • most of you guys seem to be in awfull hurry to make loads of these slides (i know, they break, but not THAT often right??)

    What i do is take a file and file a line all around the (wine)-bottle which i hold in place with some glue clamps, then when te line is deep enough i knock with a wrench or another blunt object laying around on the bottom, and it falls of magically. Takes about 15 minutes.

    Oh, and then you got to find some concrete and "rub" the sharp edge off the bottom of your slide.

    No power tools needed!

    • Hey, we got a boat load of friends. They all need slides :-)

  • A word of caution, wear a dust mask if you are cutting/grinding glass. Inhaling fine glass particles just can't be very good for you.

  • Got to, eBay for a good bottle neck cutter http://www.ebay.com/itm/STAINED-GLASS-SUPPLIES-BOTTLE-JAR-CUTTER-ST... 

    This bottle cutter works fine provided you set it up as per instructions.

    I've not had a failure using this cutter, although to be fair some necks I've had to do a bit of extra grinding because I haven't got an absolutely clean cut. Tungsten carbide tips seem to work best....you only need to do a fine score line, and don't overlap the cut....one complete circle around the bottle neck only. Don't worry if you can't see the score line, If you have a good cutter, you can hear it doing its job rather than see it. Then use the hot/cold water method....might take a couple of goes alternating between hot & cold, but I've not had any difficulty. I use aluminum oxide sandpaper to smooth the edges after cutting. Also dip the glasscutter tip in metho before cutting, for lubrication. If the slide is too big for your finger after cutting, use some of the softer (loop) side of velcro, glued around the rim of the slide on the inside to reduce the width and give a bit of grip.

  • If you gents are going to be making a lot of slides invest in a wet tile saw with a diamond blade, I think I spent like $175 for mine. I can make the 2 cuts on a wine bottle in about 10 seconds, clean cut every time. I smooth it out with a dremel and done. Now that being said you can use the saw for a number of other things, even cutting tile if ya choose.

    • Hmm, I think my mom has one she bought for tile cutting years ago. The bathroom is done so she may not miss it.
