So you hit the web and see all sorts of weird and wonderful techniques to cut bottles down. Who’s to say what is wrong or right? I guess it’s just down to what works for you. There are some that just seem a bit messy, or without much chance of working neatly on a regular basis. One of those was the burning string idea – where a string is wrapped around the bottle, soaked in kerosene, acetone or lighter fluid, and lit . I’m intending to try it one day, just for the ‘Robinson Crusoe’ experience, but it doesn’t appeal logically. At some point, the string will fail to form a perfectly straight and joined line around the bottle. It’s bound to be a technique sure to end up with a jagged step. I’ve similar doubts with the hot oil inside the bottle technique, which uses the fill level to make a thermal break rather than a score. At this point of learning, I think it needs a clean scored line to make a clean break, just like cutting flat glass with a traditional handheld cutter. That means either making a home-made cutting head device or buying a retail bottle cutting device.
There’s some quite interesting ideas on making your own device on Youtube:
Through work, I can source various types of high quality glass cutting heads, so this could be a good option for the future, especially if I need to have a jig that does smaller miniature bottles or large bottles or jars like demi-johns that might not fit on a shop-bought jig.
Right now, for simplicity, and speed , I think it’s the bought option for me. Looking on Ebay, those few that crop up for sale seem to attract plenty of bids and retain a lot of the value, so it seems like a no-brainer to give it a whirl. Worst case scenario, and I don’t get into it or keep it going, it won’t be a bad thing to move on.
