Cutting Glass

I'm trying to cut some glass tops so I can put it over the tank and I was wondering is there anyone experienced in using a glass cutting tool and any tips in cutting glass?

I use this tool by pulling it in a straight line over the glass and it cuts into it a tiny bit. Then I use the end to tap it a little and snap the glass where I cut it.

I did this but its a little bit harder than I thought it was. I haven't successfully cut a straight line yet. Am still practicing and if anyone can give me any pointers that'll be neat.

Such as how to tap the glass, etc.

thin glass 1/8" is best for those glass cutters.

Save yourself a headache and a ruined piece of glass.

Take it to a glass shop.

How do they charge for their services? Thickness of glass or the amout of cutting?

It's always a neat idea to gather skills, even small ones.

If you give a guy a piece of glass already cut, he'll have that piece to use.

If you show him how to do it himself, he can make his own piece whenever he wants for a lifetime.

(LoL, trying to revise it from the fish version)

You get the point I hope. Its all too easy to give it to somebody else but if I knew how to do this myself, I wouldn't have to depend on someone else later on.

It varies with the thickness,but with something this small it's hard to tell.I would be very surprised if they charged more than $5.00.I had some holes drilled some years ago but I can't remember the cost,but I do remember that it was lower than I had expected.

Be charming,and tell them what it is for and they may not charge anything.

It's important to use steady, even pressure when using the scoring tool. My advice is to use a straight edge to guide your cut. Also, make sure that you're going all the way from edge to edge.

Make a couple passes and then place the glass over a table edge at the score line. Apply a little pressure and it should snap at the score line.

Good luck!

Probably the safest way and you'll make sure you get a proper job done.

They would charge on time taken, especially for just a cutting job when the glass is supplied already.

Yep a small firm would likely be better. If you catch the chap with nothing much on at the time he may just do it on the spot and send you on your way.


If you do want to have a go yourself have your glass on a table or something solid rather than the carpet which gives a little. You can use a cloth sheet to avoid scratching the glass if you want. Mark it out beforehand to the correct size. Use a straightedge to make the cut neat. Apply firm pressure (but not excessive) to the cutting tool and, cutting away from you, make one solid cut from end to end of the glass and make sure you run off the end of the glass. You should hear it crackle nicely as you do it. DO NOT go back over the cut again to make it deeper, you only need one cut, do it right first time. Now pick up the end of the glass holding both sides of the cut and tap the back/underneath of the cut from one end to the other with the end of a wooden hammer handle or similar, this will spread the cut stresses though the glass thickness. Tap gently over the whole length of your cut and if you get it right the pieces should just fall apart nicely.

Have a go on some spare scrap pieces first just to get the hang of it but it shouldn't be too hard.

If you want to clean up the sharp edges use a whetstone or carborundum sharpening block. You just need to knock the corners off the edge. Alternatively you can use some fine wet'n'dry paper on a block for flatting off car paint jobs.

Cutting glass is very easy. Just press hard enough to hear clicking. And if it does not snap very easy, then it is not going to cut clean. I made a whole aquarium with a 8 dollar steel roller glass cutter

x2 on the NOT scoring it more than once. A drop of lightweight oil on your cutter wheel is usually recommended as well.

LOL.

I practiced it a few times and I still haven't perfected it.

Only problem now is that I ran out of glass to practice on and I ran out of money to buy more glass.
