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.
There are folks here that have done it successfully, but I have never been able to make it work, so I gave up.
The trick is to make a relatively deep and narrow score line. You want a lot of stress built up on a very small area for the relatively small change in temperature to have an effect. The broader the stress region, the greater the difference in temperature will need to be and the lower the likelihood of a clean break. I've tried a few with some success, but stopped mostly because most bottles won't be big enough diameter for my ring finger.
It helps to have a steady rest for the bottle and the cutter. Screw a cleat down to a work surface so you can spin the barrel of the bottle relatively accurately. Use the cleat as a steady rest for the glass cutter and you may get better results than free handing the job.
Expect low yield and don't worry about it since you're trying to get something for nothing. Glass is a tricky material and beer bottles aren't exactly precision working stock.
Or purchase a slide if you want to get one right every time.
I have not had any luck either, but if you are going to do it try a wine bottle instead, the end result is a better slide than a beer bottle.
I bought a glass vile slide over at cbgitty.com.
Discovered the label from those tiny little bottles of Jack Daniel's fit inside the vile and adds a bit of character.
The only problem is keeping it mine, everyone that sees it wants it.
Bought a glass tube at Best Buy, in their guitar dep't.
I use a tile wet saw with a diamond blade and cut wine necks with it and works really good, now I know not everyone has a wetsaw but i'm not sure a 4 1/2 grinder with a diamond blade wouldn't work. Gets kinda pricey tho.
I rarely cut glass slides these days...my buddy Ian at Diamond Bottlenecks does the job better, quicker and cheaper than I can (I buy mine off him 20 at time as it just takes so long to do it myself)...but when I do cut slides I use an angle grinder in a bench jig with a diamond coated disc...score it about 1/2 way thru the thickness of the neck then snap it off..no messing with making a a little scratch with a Dremel or glasscutter. The real hard work is flatting the cut down and polishing it. To do this right involves a lot of experimentation, some brute horsepower, proper abrasives, a lot of elbow grease..and a lot of broken glass. Wine bottles (and some olive oil and sherry bottles) are the thing to use, beer bottles are generally too wide a taper and thin-walled.
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.
Woozers, my Dad gave me a tile cutter, I didn't want it but took it to please him, now I am glad I did, thanks for the tip.
Hmm, I think my mom has one she bought for tile cutting years ago. The bathroom is done so she may not miss it.
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.
