In this article, Dania Kraster will show us the process of making a glass cutter.
Danya decided to make a custom, or home-made glass cutter. For purchased or low-quality, or very expensive. If you thought that you can cut glass with brass, then on a hardness scale, brass is softer than glass. Need something harder.
For example, this diamond cutter.
You can use it and hold it in your fingers, but it is no good. Therefore, now the author will get confused and make an awesome pen for him. From such rubbish. It is not even known what it was.
Clamps the part in a vice and unscrews all the parts that can be unscrewed.
Dana’s steel washers are not needed in the melt, and indeed all this canoe will not fit into the crucible.
Therefore, it is not sparing it can be cut in half.
Throws in a crucible along with all the junk that he unscrewed, adding brass taps.
Opens the cylinder valve, and sets fire to the hearth.
There, right in the heat, puts a crucible and let it warm up.
During this time, he warms up a sandwich.
At the second stage, when the brass is heated, it takes out a crucible and falls asleep the whole thing with boric acid.
It will collect slag from the melt, protect it from oxygen oxidation, and with it all scrap will melt faster.
While brass is melting, it cuts off a piece of pipe, which will be a form for pouring.
Danya wants to get a thick blank to firstly see what brass shrinkage is, whether it will flood without pores in such a volume.
And along the way, get a lot of brass chips, which will be needed for the following projects.
Meanwhile, the crucible warmed up to 1000 ° C. And this is in the gas hearth, for a minute.
He takes out a crucible and pours it into a mold.
Yes, he forgot to scoop up the slag, but fortunate enough, there was a small amount of it.
This practically did not affect the quality of the disc.
Brass requires a higher temperature for casting.
Honestly, for projects where the ease of detail is not important, the author will be happy to use this method.
Even it pours, due to its higher density, much better than aluminum.
Cools a blank in a bucket of water. It is massive enough to wait until it cools by itself.
And knocks her out of shape. Even though there is a seam inside the pipe, the billet gave sufficient shrinkage so that it could be easily knocked out of the pipe.
In general, sand is not the best option for casting. Especially if after this process is turning.
Cleans places where sand is ingrained in metal.
And now it's time to carve out some kind of handle from it. A rather large number of shells formed on the surface, with a depth of up to 6 mm.
All of them must be removed in order to reach the delicious core.
When turning, a large amount of cool brass chips is formed, which should not be thrown away. It will come in handy for other projects.
A blind hole will be drilled with a milling cutter because a hole has formed at the top of the blank.
And the center will not work. And the drill, because of its length, will hit.
Those parts in which there is sand, but it can be soldered into an array of metal, cuts with a hacksaw.
Also, in this process, the workpiece is fooled, so that you can center, and use the tailstock, for example.
Continues to sharpen. Danya did not pre-sketch the pen, so the form was born in the process.
It is good that brass can be filed without any problems. Directly on the machine outputting spherical shapes.
Drills a hole at the end of the handle, and rushes to process it on a milling machine.
You need to make a couple of cheeks with this tool.
Firstly, it will be more beautiful.
Secondly, with the help of them it will be easier to position such a glass cutter in any devices. For example, for cutting round glass.
Here is such a thing.
Still, he did not follow, and some bolt soldered into the blank. Next time through the bars will pour.
But that is not all. The cutter is square, and the hole is round.
Not quite right. Therefore, now Danya wants to sharpen the head into which it will be possible to solder the cutter and insert it into the handle. Measures the pen.
Perhaps it would not be superfluous to draw a sketch so as not to mess up anywhere.
Pours coolant into a bottle with a spout.
And he touches his head.
Slices the workpiece to the formation of a piptic, which breaks off the disc.
Fit to size.
So, it's time to make a groove in order to insert the cutter.
After these procedures, the cutter tries on.
If everything fits, but everything is, what is most surprising. Starts soldering. Will be heated with a gas burner.
A principle that is as simple as a broom. The compressor blows into the tank, gas vapors exit through the burner.
They can only be set on fire.
Heats up the head.
And, using flux, solder the cutter to the head.
Danya did not fool with high-temperature solder and filled everything with ordinary tin.
There will be no serious load, so it will ride.
Having tried his head on the handle, he places a place for the clamping screw.
Drills and cuts threads.
As a countersunk screw, Danya decided to use a piece of screw with a thread in which the slot is sawn.
All this business should be tempered so that it was stronger.
After soldering, the head is cut to make everything look better. Indeed, it has become much better.
It remains only to direct the marafet by polishing an almost finished tool. This can be done by dremel. And ordinary, that is, green GOI paste.
Polishes the head.
Goes to grinding the handle, especially the cheeks.
There were traces of the cutter and now Danya will bring the whole thing to the mirror. Three types of abrasive will be used. As usual, coarse, medium and small.
If you focus on the average, you can achieve cool satin on the metal surface. He also gets into the pocket of cool chips.
Well, after the smallest stone, it polishes with the same composition.
After polishing, he wipes the handle with kerosene, he will completely remove traces of paste.
The rest will also be polished.
As a result, we got such a glass cutter from trash that lay and was waiting for its fate.
Now let's check out how he copes with his tasks. The author pounded a sufficient number of glasses until he realized how to cut them. Without pressing at all!
It practically does not make a sound when cutting.The glass is quite even, it is especially important in the manufacture of stained glass and all kinds of small elements.
Look at this cut, it is almost invisible!
But glass breaks without much effort.
This glass cutter was made by Danya Kraster, thanks to him for a beautiful solution and a useful idea.
