Okay, this is up right here, or rmcrd.com.
My name is rmcrd, I'm going to be doing my most preferred method of doing the cutting glass
bottles.
So you look around and there's the whole, like, tie a string around the thing with, like,
rubbing alcohol on it and then set it on fire.
Please don't do that, that doesn't work at all for me.
I've tried the dunking method where you kind of heat that you score it and then you
view throw it in water and you kind of heat it.
Now, then there's also the method of cold water, hot water, cold water, hot water after
you scored it.
I think the most important thing throughout this whole process is one is the glass.
It's self.
The bottle itself needs to be a certain kind of quality or more or less determines how
it's going to crack or, or, or, or thumb up part.
And then the second part is really mainly, um, your kind of what, uh, what we're less.
And the third kind of most important is how you score it.
So, um, there's these glass bottle colors, this one's called green, something or
other, uh, you want to make sure everything's all short up and tight, um, and it's kind
of a night, everything's at a 90 degree angle before you start scoring, uh, so I've got
a big wide bottle here, um, you don't want to score it on a bin, also, uh, that makes it
really difficult to, to do that, um, I tried to make a little high ball glasses, those
are pretty popular. And, uh, really, if you really, really want, uh, if you have a favorite
type of bottle, and you really wanted to go successful, I would suggest, you know, practicing
on three or four cheap wine bottles first. And then once you, uh, kind of get the process,
kind of okay, at least we're going to do good ones, uh, then start, uh, get your three,
three that you're going to, one out of three that's going to go over easy and easily,
whether I'm going to do much sanding. So, the idea there is, you know, I've got two nice,
great-goos little pint bottles that are really cool looking, uh, small, tall glasses, um,
and I've done a couple of those, but really, your best bet is if you want us to go
easily, and you don't want it to be a big pain to have to sand everything down, just buy
three of whatever it is, bottles, and then, and then go from there because having to sand down,
even just, you know, even having to sand down like, you know, an eighth of an inch is just ridiculous.
So, so I've got my kid here, my two-year-old, and he's got his thinking out of design.
So, whenever you're working with stuff, little bits of glass, you're going to flake out
when you, uh, take the boatboard to it. So, that's my preferred method, um, is doing a blowtorch.
You want to grease up the bearings or the, the cutter piece, the little rolly part. So,
I put WD40 on it, you can use, like, you know, like a regular oil, or, um, I think really anything
as long as it's not going to make a massive, the mess. So, I'm making sure the roller is nice,
and this one's got like eight different blades on it. So, I'll rotate it out every once in a while,
I'm not sure what the math is on it. But the important part is getting it all short up,
and everything at a 90 degree angle, and get yourself comfortable right before you score.
You want to be in a very comfortable spot where, uh, it's not going to bother you to have to move
or shuffle around. And when you press down hard, you don't want to press down too hard,
because you're going to flex it, and then that's going to change your score line. So, you mainly
want to push the blade, close as you can to the blade, push the blade up against the bottle,
but don't use too much force to where you're bending everything in and you're changing the
score line. So, I usually kind of want to do a first-built pass around while you're
dotted on there, and just see how it feels to score it. Just let it lightly roll around.
And this does two things. Once you do it lightly rolled around, it kind of goes through any kind of
outer outer, maybe you've got it on a sticker or something like that. You can kind of cut through
the sticker first, that works pretty good. But really, it's just to get a feel for how hard you're
going to have to push, and how hard. Now, this one I'm doing really, really tall glass,
so I don't have a lot of play, and I'm not in a comfortable spot to actually perform this.
So, I feel like I might put it in the bicycle to get it to hold tightly, and so I'm not
like wrenching it around. I'm not feeling comfortable by myself, but there's not an easy way
to get it in the bicycle. So, we're going to do here. I'm just going to do one glass at
score one glass, because it's not exactly that very fun. So, you'll do that crack. You want to
get that crack, it's down. And some people say more and it's going more than more and it's
blah, blah, blah, blah. I've always wanted to score it once. You're done. I think it's all the way around,
but you're the sound. It'll just start crumping. So, it's really, I've heard, I've seen two
different methods where they just keep scoring it. From what I understand, once you score it,
you're done. If you do it incorrectly, or you do it uneven, or whatever,
you're done. From there, you can just try to sand it down. Now, I've seen some plates
that you can buy big metal plates, and you get some kind of sand, and you can sand the
glass down using a real setup instead of just sandpaper. I've got like some 60 grit and 120 grit
that I'll use on that portion. So, I'm going to pause it for a second and pick this back up
once I'm ready for the next step. All right. So, I've got the little blowtorch here, please.
I actually use this a sweat pipe. You can actually take sugar and put it on up an anon.
I'm going to use some crumber labanan and type of sink. The same kind of stuff, people use some
crimbley, except it's a giant tank instead of a small tank. So, the amount of heat I put on here
is just enough to keep it going. Just enough to keep it from blowing out. Maybe a little bit more
of your impatient, or you got some thick glass, you're going to have to run into, but the more
patience you have, the better. So, what I'll do is I'll place the torch, obviously you need me away
for me. Then I'll probably dead in for you, buddy. Then I'll take a piece of paper so I can easily
slide the glass around and I just take your time. This is actually a better luck and colder weather
believe it or not. It makes sense because it's that transaction from going from hot to cold
the hot cold is what makes the weakens the bond where the score line is. And what I'll do is
I'll let it get hot. Spin around for a while. Let it get hot to the touch and I won't really put
a much heat on it until I blow it a little bit. So, I'll let it roll around for maybe 20 seconds or so.
Let it get hot and once you start hearing that cracking, you're kind of done. What I'll do is
if I hear the cracking, I'll start blowing on it and then go from there. So, it's kind of hot to the
touch. Now this is a thicker bottle so it's going to take quite a bit more. I'll blow inside to kind
of get some of that air that hot air out of the away from the glass. I spin it around pretty
quickly. I mean, I haven't found it. Again, it's more of a luck thing slash quality of glass thing.
I can already hear it. You probably won't be able to hear it until I get to the last stage,
but I can already hear it cracking so right now it's actually scoring. You know what it's done.
So, essentially what you can do is, once it actually lasts a bit. Once it starts scoring or
spritering, you can give it a little bit more heat and then blow on it. You can try and kind of pull
it apart. I really don't know what the best method is. I think, again, once you've scored it and
then once it starts cracking, you're on a path of just hoping for the best, right?
I've found it in the more patience you have, the better off, the better luck you have most
in most cases. With the warning glasses, it's really just crappy bonds. Now, you can see the
seam on the glass, going up the middle of the bottle. You'll really notice it when you have to
when you're done with the scoring and you'll see the score, you'll see where the glass
was melted together and you just see this ugly seam going down the middle of it. So,
then it'll be uneven, you know, uneven glass. Yep, we done. So, we got about all the around
perfect, except we have a dent going in towards the glass and it goes down about an eighth of
inch. So, essentially, this is not a perfect cut, so we would probably just, on this one, we probably
just can it or just follow it down. I have that natural dip in the glass, which is fine. I mean,
it's not going to be perfect, but generally if it's not a big huge jagged edge, you can kind of
just give it a, have it a give away for that one. So, normally I'll do those, it was kind of a give away.
Now, I'll move to the kind of sanding portion. I've tried a diamond sander for a Dremel tool,
that's way too harsh. It gets hot and then starts flexing, you know, flipping the glass around all
of the place and you just have glass shards going everywhere. We've got Jesus, this is 60 grit.
The 60 grit, if you're going to work on it hard, obviously, but the 60 grit is just going to
make it really, really coarse. You're going to have these big coarse things in the glass. If you
can avoid the 60 grit, use something like a much, much smaller, but not too small. Like here's
an 80 that wouldn't be too bad. I think even the 60's going to be too much for the, so the 220's
you're finishing or like the 320's going to be you're finishing. That's just to give you that
smoothness on the edge of the glass. And again, it's really, really user preference. If you decide
that, you know, you want to super smooth and you want to go around it edges, you're going to want
to do it like that way. Now, what seems to be a good way to get at it pretty easily is if you
tape, put masking tape on the surface and kind of tape the sander, the sand, the the glass down.
And then you can kind of rotate around it, it's durable. And I know I'm making it pretty
ridiculous noises right now. But you can kind of rotate it around in a circle until you get
kind of a flat surface all the way around. Mine is still a little dip here in the, in the glass
side that I just did. And once you spin that around, you get a nice flat surface, then you can
start finishing off with something like the 220. And I can say, you know, as far as using a
hitting it with a dribble, you can hit it with a dribble. You just have to be very careful
about hitting the glass. Once you start hitting that glass, chunks of glass will come out and
then you're just doing a lot worse than you were before. So you might be able to have some kind
of special glass, there might be some kind of special glass dribble tool you could buy.
But from what it sounds like mathematically speaking, once you hit the dribble on it, it's
going to get hot, right? So unless there's some kind of special tool, dribble tool that somehow
gets rid of heat and friction that stretches as impossible. So it's probably going to be a manual
process. And again, just just spinning that thing around and getting it the best. All the other
methods I've looked at, all the other methods I've tried are either really take a really long time.
The hot cold method, that you scored it, it actually works, you know, get a hot cup of tea
or a hot hot thing, a tea and then just cold water and you alter any back and forth.
That worked, but it worked just about as good as a torch method and the blow torch method takes
a lot less time and you don't have to sit there and wait for everything. So I hope someone
helped this out. You can also make some weird tea light things. There's all kinds of different
things you could do with once you've cut glass or you had the glass cutter for the bottle
glass cutter. You can do all kinds of fun stuff. But I just try to make cute little high bottle
glasses and great goose bottles and nice, nice looking glasses. I'll give away sometimes the
little mind sets of similar looking mind glasses, so I'll have a degree in one, so I'll have
like four in a set or something. Anyways, we'll see how this goes. Appreciate it. Thanks.
