Tempered Glass Table

I was thinking of making a tempered glass worktable or desk, and was wondering if it was practical.Would it overheat from a left out soldering iron?How much weight would it hold?Would glass for the outer layers be better?I'm a complete and utter noob when it comes to glass and most furniture, so any help would be appreciated. Also my worktable is here.

Why are car windshields laminated? Answered

Side and rear windows are tempered so that they shatter into relatively harmless chunks on impact. But windshields are laminated, so that even though they shatter, all of the pieces are kept in place. Why is this? It seems that if a laminated windshield shatters/spiderwebs and remains in place, it would completely obscure the driver's vision while he is trying to control the car. Additionally, if someone is thrown from the car, through the windshield, they would be cut by the glass shards that are stuck to the laminate. So why are windshields laminated, or more importantly, why aren't all windows in a car made of the same type of glass?

Glass Desk

So I'm in the middle of this rebuild of this stand up desk that I am finally getting around to. Now I tore off the old laminate, it was cracked so on, and so on. Now I was going to just put new laminate on it however, I sanded down the wood directly below and while I was rearranging my shop I  placed some glass I had laying around on top of it. Looking at it I realized I wanted to put glass on it instead of laminate.... (Thought process incase anyone is interested.... No one? Okay moving on.) Two questions.  One What type of glass should I use for the desk. I know tempered glass is safer, however I also know it will break much easier. Plus, the glass wont be floating with nothing below it so its not like if it does break glass will go everywhere if I use normal glass. And I don't want to use plexiglass because I don't want to have to deal with scratches.   Two Can I go to Home Depot and get glass cut to my dimensions needed for the desk?

Tempered glass screen protectors - understand and beware!

I recently had the joy of needing a new screen protector for my mobile after being dumb enough to drop it on gravel. The hard cover took all the impact but the film protector on the screen was scratched badly. Was old and partially worn anyway so I decided to upgrade to a Tempered Glass screen protector. Being somewhere rural I had no chance to get one in a shop so I ordered online. With no intention of advertising for some sellers, I collected a few links so you can check what I am talking about: Item1 Item2 Item3 Item4 Item5 Item6 So, what is my concern with these? They all can be found on amazon and other online services as well as on local markets... As I said I ordered a glass screen protector. If you check these listings and even some of the packing you will notice they all have a thing in common - being shatter proof and of 9H hardness. I also love this video showing how to remove and fix a glass screen protector! The last time I checked glass had one very distinct feature: It is hard and before it really bends it breaks - unless you use fibre optics of fibre glass cloth... What is my concern and warning here? Pretty simple: Stay away from expensive scams! Some claim their screen protector is only 0.25mm thick, even the 0.2mm one I measured was over 0.5mm with the glue... The hardness of 9H refers to the so called Moh's hardness - look it up on Wikipedia if you like. That means these tempered glass protectors would have a similr hardness than a diamond, or at least close to it. Problem is that they are made from plastic to start with and not glass at all. They claims that the screen protector is flexible because it is so thin - again a fake! Even the thinnest tempered glass will shatter if you bend it enough, not so these plastic ones. If you think I am making all this up try to use a really sharp knife or deburring tool and cut the thin sides of one of these protectors. All the ones I tested could be cut quite easy - and I though glass can't be cut with a kinfe... A nice website showing that the scratch resistance is far from the claims can be found here. And a video showing how a real glass screen protector sounds and breaks can be found here. So is it really all bad and should I avoid getting one? Not really if it is only for the added protection. To be clear here, and without the intention to blame any of the above sellers, some protectors actually do have a top layer made from glass and you can hear it as in the above video - it sound solid and not like plastic if you tap it with something hard. Another factor is the simple fact that plastic absorbs impact much better than glass. So where a real glass screen protector might shatter and crack like in the above video, the fake ones might one get a nasty dint or scratch. But you should be aware and clear about what you get and what to expect from it. These glass imitations are made from a strong polycarbonate plastic, similar to the stuff used for bullet and explosion proof "glas" windows - if you every watched the Mythbusters you have seen the big sheets I mean. The top layer of these things is specially treated to repell water, oil and dirt, it also gives the surface the good scratch resistance. The technique is nothing new, camera lenses, plastic sheets and the clear covers you see over the timetable at your bus stop all use it. The new thing is to intentionally mislable a product to make the consumer think it is glass ;) What is the real difference for the user? Check this video. Here a guy performs a drop test with a real glass screen protector. Thing is once the protector breaks the screen itself is broken too but until then it was not too bad. Here it is demonstrated how a real glass screen protector reacts to certain types of abuse - one of the reason I decided on glass. Compared to the plastic counterfeits just the sound on the glass is worth it, but I think the hacksaw was best. Another video from XDA gives a bit more info on how the glass is made - if you can't seeing a phone being abused then don't watch the drop tests at the end ;) Glass with these hardness levels and types of surface protection will give the user a long and worry free use of the phone. The plastic fakes will perform at a similar level for some time but will show signs of wear long before even the top coat of the glass one fails. Both types have their uses and if the fakes would be labeled correctly the user would actually benefit from that. On bigger screens like a tablet I would actually prefer the plastic ones to prevent damage once it needs replacing. On a mobile used in less than perfect conditions I would also go for plastic as it usually is a bit thinner and will fit better within quality hard covers. But when it comes to real abuse like using with dirty fingers most of the time or mostly outdoors where a lot of dust and fine sand can be involved I always go for glass. If you paid attention to the surface treatment then you already realised that the plastic and the glass are in the same region, making them quite scratch resistant. Still fine sand or metal dust will scratch it.... The difference is in the hardness of the actual material that was covered with the oleophobic film. Glass will not give in any way, where plastic is much softer - so not to be confused with the surface hardness! This mean that sharp and point object will easier penetrate the plastic than the glass, something to be considered if you often ecounter harsh use. In terms of actual protection we need to differenciate between surface quality and actual screen damage. After all when badly scratched we can replace the protector but if the display got damaged we are back to square one. The surface hardness was already covered so let's move on to the screen itself. In some of the above videos you can see the abuse a screen might see in normal conditions, and if we would not drop our phones so often repair shops would not be at every corner LOL I have done quite a few screen repairs, mostly for friends and work mates that did not want to pay the hefty extras in a repair shop. From there I got the stories on how it happened and in almost all cases the screen cracked when the phone landed on the corners. In one case the screen and glass protector failed, including the actual display when the phone was dropped out of a 4WD and landed screen first onto a rock. A glass protector will spread the (direct onto the face) impact force onto a much larger area, where a plastic one will produce a dint onto the actual screen much sooner. So again glass wins in terms of actually protecting your expensive screen. But be aware that all this is useless if the phone lands on the corners!! Let me explain: Both the top glass on your screen and the screen protector have a thin layer of "glue". This acts like a shock absorber, so unless an impact goes deep enough so the pressure on the actual screen is too much only the protector should fail. But the screen itself is a tight fit into the frame of the phone, so all side and corner impacts go directly into the glass. As the rest of the glass has no way to give or go the stresses will crack the screen. How should I treat my phone with the new screen protector? Exactly the same way you would without it of course. But if you don't have a proper cover that offers protection of the corners you should invest in one. Having a quality protector and a good case does not mean your phone can be used as a football, see it as an added insurance in case something does go wrong. For obvious reason it can also pay off to have a spare at hand, if something bad happens that requires replacement of the protector you won't be left with an unprotected screen ;) Last but not least, double it up: For people that already know their screen will see a fair bit of abuse in term of scratches it is a good idea to put an extra film protector onto the glass one. Once it is too scratched you peel it off and replace it, while the glass protector gives you the actual protection for your screen. Corning Willow glass As time of wrinting Corning Willow glass is the only "flexible" glass on the market, unless stated with your flexible screen protector you can assume it will be just plastic. I did not list it above as this high tech material is mainly reserved for displays and at least to my knowledge is not available for screen protectors, although I will stand corrected as I have to assume some big players use it for their protectors. The material is actually a sandwich where an ultra thin sheet of glass stis bewteen two layers of durable coating, read it up on their website it is quite interesting. It won't reach the strength of their famous Gorilla glass so without an outer plastic that has the additional oleophobic coating it won't provide the strenght of real tempered glass protectors. Some phones like the Galaxy Round and the fleixble HTC phones use it for example.

Where can I find someone to do a small tempered glass job?

While replacing the halogen bulb to my outdoor deck floodlight, I dropped the plastic cover and the tempered glass panel shattered.  Where can I find a vendor to provide a 3.5 x 4.5" replacement panel and what kind of glue do I use to replace it?

I need an idea of what could be made from two curved glass deli cabinet doors.

Along with a few flat glass shelves, I was given two large curved glass deli cabinet doors as shown in the image below. They still have the aluminum bars attached to the long ends. One the top side that was formerly attached to a hinge mechanism and one being the lower side that formerly held a rubber seal. I only have the doors, as the rest of the cabinet was used for another purpose or recycled by the previous owners. I'm trying to come up with a project to repurpose them for, but I'm drawing a blank. They are about 4 feet long and 2 feet wide with no cracks.  They appear to be tempered glass and are very heavy. Here are some ideas: -  large vertical display cabinets made from wood with the glass doors on the front of them might work by using the short ends as the top and bottom. - large horizontal display cases made from wood with the glass doors as the top or front and access to the rear. - Some sort of greenhouse window. - I eventually would like to build a house out of shipping containers. Incorporating these into the plans as windows would be cool as long as I can figure out how to frame them out to give a good seal. perhaps as a skylight? (Of course, not being double paned, they wouldn't have much of an R-value). - Something artistic that can utilize the glass panes and be hung on a wall or used as a display. I have access to a Hackerspace in St. Louis, Missouri with plenty of tools and other raw materials. The pieces are so large that I'd have to work on the project and clean up each day rather than leave the project out. It's a shared space, so I don't want my stuff to be in the way of others. Any input from the Instructables community would be helpful.

Restoring a vintage child's pull-wagon. Anyone know where to get replacement wheels?

I am desperately looking for replacement vintage-style wheels for a pull-wagon that I'm restoring. It's in rough shape but all the bits are good except for two wheels which are beyond repair. I also have a strange old 3 wheel kick scooter that needs a wheel. I've scoured the 'net under every heading I can think of with no luck. Can anyone help? I need metal disc-type wheels like the ones in the photo. This is a pic of an old wagon I simply cleaned, waxed (including the wheels) and turned into a coffee table using a piece of tempered glass someone threw away.  I've since added those transparent little silicone "bumpers" on the corners to stop the top from sliding off.

How do I construct a maser?

So I have mentioned before about my plans to build a HERF gun using a magnetron powered by a highspeed motor w/ permanent magnets that serves as a generator(it's driven by a minature gas turbine engine). But the issue of collimating the microwaves into a beam that can travel at least 4 miles without significant diffraction is an issue I'm still working on. Now magnetrons have an efficient of roughly 70%.  So here's the idea: The magnetron's output coupling loop(antenna) will be inserted into a highly tempered glass cylinder that is attached to the top of the magnetron and the cylinder will be filled with either hydrogen gas or (anhydrous)ammonia. The oscillating RF field will pump the gas molecules at their microwave region resonant frequencies(if I use ammonia that will mean I need the magnetron to produce peak power at 24 GHz)and stimulate microwave emission by the molecules(population inversion). Has this technique ever been demonstrated experimentally? I know that RF radiation can be used to heat up hydrogen gas into plasma but maybe there are some references to masers constructed in this fashion.
