Step 1: What you will need
1. A glass cutter (commonly used for stained glass). I already had one but you can get it for $4
2. 1/4" x 6" x 3' pine board $3 each (buy two) or one 4' length if you can find it
3. 5/16" glvanized wire rope clip $0.88 each (buy two)
4. Wood glue (I like Titebond II, $3 for 4 oz)
5. optional 5/16" washers $0.08 each
Total cost: about $12 if you already own the glue
Total time: 1 hour of Making time + 2 hours waiting for glue to dry.
Tools: I don't have a garage in San Francisco, so I made this at the Techshop (SF) where I used a bandsaw, clamps and belt sander (optional).
Step 2: Cut things
2. In two of these 8" pieces, cut a v-shape (right triangle) at one end. Make these identical. The v shape should be big enough to accomodate at least half the diameter of your wine bottle.
I used a bandsaw because it is so fast and easy and precision is not important here. As a wise man once said, "don't let your project turn into an anal-retentive-neurotic-nightmare". Ok, he said this about making beer but I like to keep it in mind pretty much all the time.
3. Use your wine bottle to mark approximately where it contacts your v-shape.
Step 3: Mark and drill
5. Decide where to position your cutter (it could actually go anywhere between your two wine bottle lines). If you want to cut beer bottles as well, move the cutter in about 1/2" from where I have placed it in the pictures.
6. The galvanized rope clips will serve as your clamps. Plan to place them near the bottom half of your glass cutter. Lay everything out and mark it. Check that you can raise the cutter enough to make contact with your bottle when it is placed in the v-cutout.
7. Drill the 5/16" inch holes for the clamps.
Step 4: Glue and screw
9. Screw your glass cutter onto the second v-shaped board using your clamps. Use your wine bottle to check that it will make contact with the cutter when the jig is put together.
Step 5: Glue some more
11. Wait, drink another beer, check your watch, wait some more, check watch, etc.
12. Glue is dry!! Take off your clamps and you are done! I sanded everything up on the belt sander to make it pretty but that is optional. Pretty is so pretty, though.
Step 6: Cutting the wine bottle
14. Bottles with labels, label goo, etchings, or printed glass will not cut as well. You want smooth, clean glass. A little hot water or "goo gone" helps to remove labels.
15. Heat your bottle with a candle or lighter along the score line. Now run the bottle under cold tap water at the line. Repeat a few times then try to gently pull the two halves of the bottle apart.
16. You now have a cup and a possible chandelier! Now don't cut yourself before you smooth out those edges.
17. Bonus tip: a dremel with a diamond bit works great to smooth the edge, then sand with sander bits and polish up if you like. I got a set of 20 diamond bits on amazon.com for $5. I have also hear its possible to just place your cup, top edge face down in a bowl of sand and twist in the sand. I haven't tried this.
18. Have fun and impress your friends!
FYI. This makes glasses of one length. But without any additional construction, you can flip the cutter to the outside of the jig to make your cups about 1" taller. In addition, if you have a different size cup in mind, just build your jig accordingly (using slightly wider board-stock).

I want to make it; but, in fact, there are too many nice glasses so readily and cheaply available in thrift stores that I cannot justify the project.
One suggestion is that you advertise how you use corner clamps. Until I started using them, I despaired of simple joints. Bandsaws and jigsaws are wonderful, but the new oscillating tools make these projects possible without a shop.
i usually tie a wire around the bottle and heat the wire with a candle or torch, then place the heated wire and bottle under the tap with water running. it makes a crack on the bottle where the wire touches..
but this one is easier!
Sort of like this:
Thanks.
