Is my cabinet maker correct They are right that drilling clean holes in glass is more difficult than in wood or steel. In my opinion, they are not right to say that visible cracking around the hole is normal. They are a professional and part of the price they charge is for having the skill, experience and tools to do the job better and quicker than you ...

I used to work for a company that built machines that drilled these holes (though we did it in much larger pieces, usually 3/4" to 2" thickness). It's not a hard process, it's slightly expensive, but it's doable. The process is basically as follows: Use two diamond-tipped drill bits to cut the hole (one above and one below); Use a water-jet to push water ...

There is a product called Window Security Film which is a thin (a couple mm) film that adheres to the window and makes it exceptionally difficult for someone to break. Many lock smiths/security companies can install it. Here's a video of it in action: http://www.youtube.com/watch?v=vYdVK3BqPfk One of the biggest "problems" with it however is that because ...

Even if the windows were super thick, it wouldn't be strong enough to handle the pressure exerted by a properly positioned ladder. A ladder is supposed to be sloped 25%, like this: With someone standing near the top of the ladder, that means roughly 20% of his weight is directed as lateral force, directly into the wall or window, conveyed by the points of ...

You can't. The tempered glass will completely shatter if this is even attempted. If you absolutely must have tempered glass with a hole in it, the hole or any other shaping must be done before the tempering process.

Another angle - if it is the size of windows you are worried about, have you thought about altering the frontage to have smaller windows? It would then look less like a shop, and it would be easier to get laminated glass for the windows.

Put in a simple alarm system with glass break sensors. Dedicate it to the windows if necessary and leave it on all the time. If anyone ever tries to break a window the alarm will sound. You would not even need to have it monitored if all you want is peace of mind while sleeping.

Don't do it. Put the ladder above the window, then clean by putting your arms through the rungs. Shouldn't the windows have a way to tilt them inward and clean from inside the house? Most every modern window I've seen has a way to do that. You may want to get a ladder stabilizer:

I'm pretty sure bullet proof glass is not a viable option. A quick Google search came up with a 40" wide window for over $3k. I couldn't find anything nearly the size you mentioned, and I'm guessing the cost for increasing scale is not linear - you're talking at least tens of thousands of dollars here. My guess is that the glass would end up costing just ...

Glazing manufacturers have spent decades perfecting a spacer system that does not eventually leak and condense. They still haven't completely perfected it, though they are much better than 20 years ago. There is no way you're going to put together a system that does not eventually leak, especially with a vacuum. You'll have a better chance with inert gas, ...

Either use a A frame ladder or a squeegee on a pole. I personally wouldn't trust my health on the structural strength of glass.

You cannot cut or drill heat tempered glass. Not waterjet, not laser, not hot needle, not under water. Physics, not technique. There is no secret formula for cutting or drilling tempered glass. You can do edge work if you are careful, but you are weakening the edge substantially in doing so. IF you don't remove too much glass it may not break. If you ...

The level of cracking you're showing on the left is not normal. There is some roughness around the hole on the right which is generally normal. Actually, the hole on the right is, more or less, what it should look like when you drill a mirror or any glass. This is one of those skills that takes practice to become consistently good at. As for replacing the ...

If it's a high crime area, the typical solution is window bars on the first floor. If it's not a high crime area, I'd maybe not panic too much. Most burglaries are through the front or back door or an open window. Smashing large picture windows isn't typically the first choice of a burglar.

I would not even suggest taking the chance that it could hold you up to stand on it. Think of the possible serious injury that could result if it were to break and give way when you were standing on it. You would do well to just move the desk out away from the wall and use a step ladder or stool of some sort to get up to the area where you intend to hang ...

The nice thing about renting a place is that you don't own it. Problems with the house are really the owner's problem, not yours. If it were me, especially in the situation you've described, I'd call the landlord and say, 'Hey - come clean this crap up'. I certainly wouldn't invest in supplies or materials to do it. Take a look at your lease/rental ...

Standard EMT tool for tempered glass car windows (after taping - packing tape preferred over duct tape) is an automatic center punch. A hammer and nail will work the same, it's mostly being a one-handed tool that's easy to carry that makes the ACP the preferred tool among EMTs. If you're "smashing the whatever" out of it, you're doing it wrong. It just ...

First really look for the watermarks. These are usually ultrafaint in a corner. They could even be upside down. Second look for any chips on the edges. If there are chips it isn't tempered. Third if you need the hole just drill it. Use the smallest bit you have to start and work your way to the size you need. Wear gloves but putting a tiny hole in ...

Mirrors are made up of two parts, the glass and then a reflective coating on the back. Because of this, they are not considered 100% glass and many times the town's recycle pickup (if your have one) for glass will not take them because there will be an additional process to separate the glass from the reflective material backing. Possible disposal methods: ...

This sounds like a bad plan. 550 pounds (or more, likely) is just way too much weight to try to hack something together. Even if you put a support in the middle, then you need to make sure it's perfectly balanced or you're going to crack the aquarium at the pivot point — the glass tank is going to be very unforgiving of an uneven surface. Plus, think of ...

Have you thought of a bathroom window film? It's very easy to put there, and it works really nicely. I mean one of these: They come in a variety of patterns, from plain to very fancy. I think they are easier to apply than the sprays (I've put them on couple windows without any problems). They are made to be in the bathroom so they last long, and the ...

That is not a glass break tool. It's a chip inserter. You put the microchip in the U shaped slot at the bottom, then use the plunger at the top to push the chip in to the circuit board or holder.

One cheap and easy solution is to simply purchase alarm system stickers/signage from eBay. A potential burglar won't necessarily know that there's no system installed.

Alternative idea. Test the sealer on a piece of left over tile. Let the sealer get onto the glass and wipe it up shortly thereafter. Compare the before/after -- if you see no notable damage, just put the stuff on and have someone clean up the glass right behind you.

It's really hard to assure that they won't be under load anytime in the next 50 years. Obviously, the bottles only need to break once to be ruined. Also, depending on the type of bottle, it might be hard to find lids that are waterproof, rustproof, and won't decompose. I recommend using something sturdier, like large diameter PVC or ABS pipe. It's easy ...

The type of glass by itself isn't a deterrent as most burglars don't look first, or they don't know what they are looking at. Signage is a greater deterrent. The window film as already suggested is most likely the simplest and cheapest solution. Bullet resistant glass will deter burglars once they throw a brick or take a few swings at the glass and ...

Suction cups are used with success in this situation. Search for "glass table suction cups". The cups have a small cylindrical nub that sits in a hole you will have to drill for each cup. You should only need about four. With the suction cups, the table would be secure, would have some (minimal) give when struck, and would be easy to replace.
