Just got done testing it out. Works good, and it's alot faster than rubbing the slide on the sidewalk to get the sharp edges off.

Materials:
An electric drill
A cork from a wine bottle
a woodscrew about 2 inches long
a knife sharpening stone (or a concrete sidewalk)

Cut the head off of the woodscrew. Drill a pilot hole down the center of the cork. Put the screw in the drill and chuck it up tight. Slowly drive the screw into the pilot hole of the cork.

Now, just slide your freshly cut bottle neck slide onto the cork. Wet the stone. Apply light pressure while spinning the slide against the stone. Takes about 5 minutes or so to get a nice smooth edge.

Remember to wear safety glasses (just in case).

Awesome technique!! Thanks. Can't wait to try that!
Here's a neat video that shows you how to cut a glass bottle without using a saw:

Here's the same video clip with written instructions;

I tried that technique, with mixed results. Either nothing happened, or the glass shattered. For actually cutting the neck off the bottle, the best way so far that I've found is to use a Dremel tool with a fiber cutting wheel. You don't have to cut all the way through, just make a cut about 1/32" or so all the way around the neck, then tap the neck on a table. It should snap off fairly easily. If it doesn't, cut a little more and try again. The first time I tried it, the neck actually popped off by itself.

How about cutting a hole through your car floor board , and driving over the smoothest concrete you can find. And carefully drag the bottle neck through the hole at , say 45 to 50 mph. Its a little safer than doing it through an open door.


I have a bottle cutter, it is just 2 tin "V" blocks and an adjustable base., It has a cutting wheel on one block. I scribe a light line and then heat the scribe line over a candle while rotating the bottle untill it is pretty warm( about 10 rotations) my instructions said hot at line warm at ends)  then I stick the bottle, neck down into a pail of cold water  just over the scribe mark ( the candle soots up the mark so I just use the soot mark as my line) it pops off in about 15 seconds.  If it don't come of or only comes part way I heat and dip again.

. My cutter is old but I saw some like it still NIB on ebay last month for about 25 dollars.

Wear safety glasses and gloves, I had a bottle shatter while drilling a hole in it once.

Hey guys, I just joined this forum and had to comment on this thread. I like to make my slides so that they LOOK like a nasty ass broken bottle neck, you know the kind that some good ol boy found on the barroom floor, picked it up and started playing with his new found slide/slice-n-dice weapon. To get this look break your bottle. Then using 120 grit SILICON CARBIDE sandpaper lightly sand the jagged edge, but just the edges! I'm a retired glass cutter with years of experience cutting window glass. The only part of the glass that will cut you is that razor sharp edge.

I'm not at home for a couple of weeks, but just had to grab an empty bottle for a demo pic. The bottle broke leaving me a shorty(broke it with a crescent wrench) About 2-3 minutes of light sanding and checking for sharp spots and I was done. You could ride from Jackson,MS to Chicago sitting on that jagged looking edge and not get a scratch.
