How do I cut OLD window glass to a different size?

Answer 1

Use a glass cutter. Apply a steady moderate pressure as you move the glass cutter to provide a clean etched line. Be sure to go beyond corners. Break by putting something under the edge of the piece you want to keep and apply steady pressure until it snaps.

Answer 2

USE OIL!

The most important step here is to use oil, really any oil, but specialty glass cutting oil is best. Use a new glass cutter. The cutting wheel gets nicks and imperfections as it ages, and a new one will give a better result. Dip the cutter wheel and head into the oil or use a small brush to run a coating of oil along the straightedge's length (where you'll be cutting).

Do not doddle between scoring and actually snapping the glass. Glass is weird and will "heal" in about 15 minutes, making the run when cracking unpredictable.

As the other person mentioned, but I will clarify, plate glass is just 1/4 in glass. I think they meant tempered glass. This is usually indicated on the glass a a bug, or a etching in the corner indicating it is tempered. It will not cut! It will make a mess if you try! DO NOT DO IT! Glass will go everywhere.

If the glass is that old, it may be best to have a shop do it. It still may break, but cutting glass can be tough if you haven't done it a bazillion times.If they charge more than a few bucks a cut, go down the street to another shop. We often do it for free, other shops will as well. Just remember them when you need something else.

Answer 3

Cutting Old Glass

Answer 4

As glass ages, it gets very brittle. Even if you score it with a glass cutter and then (as you would normally) snap it on the cut, it will splinter. By the way, glass is actually a liquid, you can always tell which way up a piece of old glass was in a window by measuring the thickness...the thickest edge was at the bottom....Useless info, but there you go.

Answer 5

use a glass cutter and a sraight edge measure the size 1/8" smaller to the edge of the straight edge where the cut is going o be DOINT TRY TO CUT ON THE SAME CUT MORE THAN ONCE USE MODERATE PRESURE you will hear the sound of the cut as you draw the cutter along the class
take the straight edge and put it under the glass so tht the cutting edge is level with the score mark on the glass push down on the waste part while holding the part you want to save it should break along the score old glass is more difficult to cut but you must not be frightened of it as if you are it will go wrong

Answer 6

If the old window glass is plate glass (for some odd reason), you won't be able to recut it at all. However, if it is really old this shouldn't be the case. Plate glass usually has some type of printed designation in one of its corners and you can't score it.

Otherwise, you can just use a glass cutter. But if you want to bevel the edges or do something out of the ordinary with the glass, you can take it to a local glass shop and they will do the cutting and/or modifying for you.

Plexiglass is a very versatile thing and available in a ton of different colors and patterns, so you're only limited by your imagination, and probably your budget. I'm not sure I'd try to glue the panels into place, though. I think I'd rather set them in place and hold them with little brad nails like you would the back of a picture frame, or make little strips of wood that I could pre drill and nail in place. Glue can be really messy to work with and not everything sticks to acrylic. You'd probably need silicone caulk and unless you've had a lot of practice, it's hard to make look clean and professional. Obviously, you want the best looking solution with the least amount of fuss, so I'd go to a home center or hobby store and get some thin strips of wood, 1/2" x 1/2" or 3/4" x 3/4" and use them to frame around the plexiglass. An old cabinetmakers trick is to cut the head off of one of the finish nails you intend to use and put it in a drill. Use the actual nail to pre drill the holes in the cleats so when you tap the finish nails in they won't split the wood. Or you could screw the plexiglass into the existing window frame with one in each corner and maybe one in the center of the longest edge, but it is really helpful to have a drill bit made for acrylic. They have a pointier tip than regular drill bits do, but if you don't have one, they can be hard to find, though they can be ordered on line. But you can drill it with a regular twist bit if it is new and you use a piece of scrap lumber firmly clamped to the acrylic so it doesn't crack the plexi. Go slow, but not too slow and you should be okay. Once you have holes that are a little bigger than the screws you want to use (don't try to nail them because you run the risk of missing) you just have to gently screw them into the existing frame. They don't have to do anything but not fall down, so don't overtighten them or you can crack the acrylic. Have I scared you yet? Sorry, it's not that bad. I think I'd try to just toe nail in a few small brad nails right at the edge of the plexiglass so they trap it between the nails and the existing frame. If you're careful, it should turn out fine and hardly be noticeable. I forgot to look to see if your city was listed on the Pulse before I started, which I usually do in order to better tailor an answer, but if you're near a fairly large town or city then there should be a place that can cut your acrylic to the exact size you need so you don't have to deal with cutting it yourself. Any decent cabinet shop can also cut it for you if they have special blades or at least a new crosscut table saw blade. The hardest part might be peeling off the protective paper or film. Or you could avoid the whole thing and get an estimate from a glass or window company to see what they'd charge to do it all for you, though it's pretty simple and you can do it yourself. Sorry, I didn't start out to write a manifesto, or a treatise, but I wanted to give you some options because I hate messing with silicone.

Answer 8

If you can get the glass out of the frame, use a good glass cutter and go steady. Make a score and "fold" the glass over a raised surface. You should get a result. If that doesn't work, I guess by then you're buggered!! Go to a glazier!

Answer 9

use a glass cutter and a pair of gloves and safety glasses. use a straight egde for a straight cut or etch out what you want to cut and then apply pressure to snap off or use some pliers to snap off small bits of glass at a time.

Answer 10

Use a straight edge and a glass cutter dipped in paraffin (kerosene), makes for easier cutting. Snap off with pliers
