I really enjoyed this video, found it after I lost my cork screw and looked for ways to open wine bottles with out one.

Sharing is caring.

Ah, many ideas come to mind if this works! Would it be possible to use the $4 glass cutting tool from Lowe's instead of that $45 rig he has? I'm assuming so, I would just have to make the measurements myself for a perfect alignment.

I did this with a huge whiskey bottle to make an aquarium when I was at school.

Ah, you went to a better skool school than I did - we never knew what to do with all our empty whiskey bottles....  Grin


Is it just me or does anyone else get the impression that Dan Rojas and his wife are actually out of work "infomercial" actors?...
I have no idea why, but they always kind of creep me out too - Dan strikes me as the type who always carries a supply of rohypnol, "just in case"...  Must be the over-perky bouncy personalities they have. *shrugs*  Undecided

Anyhow, back to topic...  I have a wide mouth wine bottle (the Spanish wine type with a lid rather than screw cap) that I intend to cut the base off. If the glass can take it, I plan to use it to make a chimney for an oil lamp (the bottle is the perfect size). But I'm not sure if the glass will just shatter with the heat...  I'm not sure what type of glass is used for lamp chimneys.  Undecided

Very nice approach.

Another classic technique that works is a hot-wire cutter, where one turn of iron wire is placed against the glass and heated with a high-current, low-voltage source. The key to this is having some way to apply heat just at the cut line.

Try rotating the bottle standing it upright, with the cheapo glass-cutter at the right height on a box or some sort of adjustable stand, Retort stand and clamp, perhaps? A box, books, etc are cheaper... Wink

Very impressive, not least considering he was clearly not using boiling water, but just general hot water, as he let it run all over his hand without comment or flinching.

So it's every hand to his rope or gun, quick's the word and sharp's the action. After all... Surprise is on our side.

I would say a cheap Dremel like rotary tool with a diamond cutting disk (slow speed, gentle pressure), clamped at the right level, and carefull turning of the bottle (on maybe some kind of turn table - old record player?) should provide a deep enough cut / score that is perfectly straight. Cheaper than the propper tool at least.  Smiley

Let me know if your "home made perfection" works out.
Speaking of the "Many Ideas" theory, my chief engineer on the "Queen Victoria's Revenge" says a large Rum bottle and this technique might allow us to build a bigger Nuclear Cloud Chamber.  He has this idea that if we had a big enough Nuclear Reaction, we could produce steam with it for our ship.  Somehow I don't feel it would be the same anymore.

for scoring bottles i have seen a simple wooden jig with triangle files fixed to it.
attach two planks at a right angle so as to form a L and glue triangle files (with an edge up) on the inside both boards.
make sure that the files are straight and aligned with each other, the bottle is just nestled in the corner of the two planks and allowed to rest on the files. apply light pressure and turn the bottle, keeping it tight in the corner.

wish i could find a picture of it....

regards,
Dante

That's the cold water.  The hot water is coming from a teakettle, which is just barely visible in frame.

Bottom could be used for many nifty things, but as soo as I saw the top part I thought: wine/fancy drink goblet. Wonder how that could be made?

As a wee child in 1973 I received exactly that device as a birthday gift!

I recall a price of $12usd.   Many winebottle flowerpots were made.

One thing I later learned but have not tried:  Install a tiny kerosene-bottle on your cutter handle, with a wet wick in contact with the tiny diamond wheel.   This is a trick used widely by makers of stained-glass windows/products.   Apparently the micro-physics of oil within the tip of the advancing fracture will cause the glass to part easily when guided by the slightest diamond-score line.

UPDATE:
I bought the hand tool and tried it out on a bottle of Jack Daniel's, and it worked decent enough. Was very hard without a shmancy rig like this fellow has, but it cost a tenth as much.
The top came off beautifully, while the bottom suffered hairline cracks down it. For a first attempt this is acceptable. I expect with practice, I could easily pull this off without damage.
I will try again once I drink acquire more bottles.
