plexiglass glue adhesive

I've been hunting for an adhesive or glue to build projects out of plexiglass.  The clear plastic available in many local hardware stores.  Talking to the stores I have been directed to purchase glues that they stock, but these never provide me with the bonding I am looing for.  I suppose what I am looking for is a chemical weld similar to what you get working with pvc and the glues available for those water tight seals.

Plexiglass Temporary Window

Hi folks.   I'm designing a vent that will vent outside using a vent inside a plexiglass window.  I don't know how to mount the sheet inside my chosen window.  It's a modern window that has a screw type mechanism that takes the window away.  I took the screen out, which just clips in, and expect to do something similar for the plexiglass item. I looked at some of the hardware available at Home Depot and couldn't find anything that would make this thing work.   If anybody has any ideas, that would be great.   Some pics

Deep Green Plexiglass?

I am wanting to build a lamp as homage to the Nickelodeon Guts trophy. I have everything planned out how I want it. I will build the base out of MDF and cover it in black felt, the top will be plexiglass with some sort of light source on the inside of the plexiglass box. My problem is, I have no idea how to tint/color the plexiglass a deep (not dark) enough green as to not see the light source when it is switched off, but translucent enough to light up and cast a green light. Anyone have any ideas? I have seen online where you can order colored plexiglass, but that will get expensive very quickly.

DIY Plexiglass Window

Hey guys, time for another update of what I've been up to lately in my spare time. The other day I just finished a project, where I decided to take some scrap plexiglass and install it as a window in the top of my subwoofer, just like how more expensive pre-built subwoofer boxes have them. I tried to take pictures as I went along with it. Trust me, I may only have a handful of picture, but it took A LOT. Most of the hard work was chiseling the MDF board to fit a groove for the plexiglass to sit in and make a seal. P.S.: Chiseling MDF board is like chiseling cardboard, very easy to take too much out! Also, does anyone have any ideas as to HOW I could get some of the deeper scratches out of the plexiglass??? I'll be taking it apart to re-bevel the edge of the seal once I find the damn wood router, so when I do that I'd like to buff the plexiglass out a bit. Also, I think I own bragging rights for doing this.

Cheap plexiglass alternative

So i was going to make a desk. I was gonna make it about 2x3 and make the top out of two pieces of plexiglass, with about a 1 inch hollow area between them. I was gonna put some lights in that area. However, Plexiglass is costing a bit more than i want to spend. so I found this:;=10051&catalogId;=10053 Its ALOT cheaper. However, can it support a decent amount of weight probably? No ones gonna be sitting on the desk or anything. I would say NEVER more than 50 pounds on it, but 25 is probably gonna be the maximum, and not even that most of the time. (just gonna have my laptop and stuff on it, maybe some textbooks). And im assuming a blue light LED would shine through it fine..I kind of want the frosted look (would sand it down a little bit to get rid of the "bubbles") to give it an effect similar to the lights in this: except without the notifications and stuff.

Plexiglass Book: Advice Strongly Encouraged

Hey y'all! Firstly, thank you for being a part of the Q & A community. You rule. Secondly, I'm trying to make a book form out of plexiglass. This won't be a functioning book; it will just resemble an open book. For the spine, I'm using steel. For the body, I'd like it to be a frosted acrylic (I checked in with TAP and they have a .75" that should do). However, the acrylic is pricey at that thickness so I'd like to get as much advice as possible so as not to mess the whole thing up. Here's my question: 1) How do I shape / sculpt the acrylic so that it has that nice bookish bell curve? Like so: Suggestions I've received: -3D printing (I hear there is one at noise bridge but am not certain it's big enough / available for a non-noisebridger to wander in and use) -Milling (never tried milling before but how hard could it be?) -Sanding (sounds messy. And scuffy. Maybe hard to control smoothness accurately) This will be the exterior for an interactive artist's book I'm building. If you're interested in seeing it when it's done, you can add me on twatter! By the way, if anyone has any experience with coding for the Kinect and wants to nerd out sometime, I'm down.

I need to find a way to make lexan/plexiglass clear green. Should I use window tints? Does that come in the color I want? More importantly, does it come in a spray paint?

How do you construct an illuminated kitchen backsplash? Answered

 I'd like to know how to construct a backsplash like the one shown in the included image. I've hired some guys to help me install a new kitchen and we're almost finished. They sent me to IKEA to get a backsplash, but what I saw there wasn't impressive at all. IKEA only has these ugly plastic 24" sheets under the brand name 'Fastbo'. They're a joke. So I looked on the internet for something that looked better, and found this illuminated panel.  We've already installed 14-2 cable in 3 places under the wall cabinets for undercabinet lighting. But we just assumed we'd be using those undercabinet puck lights. Then I found this picture and I want to do this instead. What will we have to do to reproduce this? What materials? What kind of lights? Where will the cables go?   I assume the panel material is plexiglass but maybe I'm wrong.  If the image does not show up in the post, you can see it here:

What thickness of plexiglass is best to use for a water block? Answered

Ok, so about three months ago I bought a 168W peltier unit off of ebay. I wanted to fool around with the cold side, the only problem was that I did not have a large enough heatsink to disapate the heat. And thus the peltier would overheat after 20 seconds. So last week I decided to make a water block out of the heatsink, the design was very simple, encase the heasink in plexiglass and add two hose barbs. Now my problem is that I can't decide on the thickness of plexiglass I want to use, 1/16" would be nice but I worry that it will break, and 1/8" is a little more expensive. Any ideas?

How to frost plexiglass (w/out buying coating)? Answered

Hey all, trying to find a way to sand about a 10x8 (inch) section of plexi (lucite technically, harder than plexi from what ive read).

Best way to cut plexiglass without a laser cutter?

I need to cut a 9" diameter circle out of a 12"x12", 1/8" thick piece of clear cast acrylic (making an infinity mirror). I've cut this stuff with laser cutters before but don't currently have access to one. I have a circular glass cutter but I'm not really clear how that does me any good - it scores a circle but the acrylic doesn't seem brittle enough to snap off nicely along a circular line. I have a jigsaw with a wood blade but that just snagged and made the acrylic shatter. I have made rectangular cuts before by scoring a straight line with a utility knife, then lining that cut up with the edge of a table, and hitting the suspended piece of acrylic with a mallet - it snaps right off. I'm just not sure how to make a circular cut. Finer-tooth jigsaw blade? Approximate it using the score-and-snap method for a many-sided polygon with a bunch of straight cuts?

How to REMOVE "Frosted Glass SPRAY" from "Plexiglass???

How can I etch a photograph of people into either plexiglass (or lucite, lexan, acrylic, etc) or regular glass?

But without using a laser etching machine? I've seen chemical etching into brass using chemicals that produces a detailed effect, but I want that on a see-through surface. I'm not good at free-hand painting, so using Armour Etch without a stencil/mask is essentially out of the question. Also, would Armour Etch work on plexiglass, even though it is a different material than regular glass (SiO2)? Thanks alot!

Can IR light from an Infrared LED pass through semi-opaque acrylic?

I'm making a modification of the Table for Electronic Dreams ( and want to expand it with white LED's that turn on and get brighter as an object above it gets closer to the surface of the table (I'll be replacing the LED's in the original instructable with blues).The only (and thus, the cheapest) way I can think of sensing this distance without cutting holes in the upper piece of acrylic is to use an IR transceiver on the circuit board and connect this to the white LED.

What types of plastic glass do not go white when bent, and what is the best cement to join it to itself, please? Answered

When I am mid-way through a project I start thinking about the next one! I want to build a small-ish fish tank with a curved front. I envisage building a former of wood and 'wrapping' the plexi-glass round it to meet in the middle at the back. I will heat the plexi-glass gently so it can be bent but hopefully retain most of its thickness. What kinds of plexi-glass can withstand being bent and not turn colour? Also, what would be the strongest kind of cement to secure that join? I intend to reinforce that join by 'sandwiching' it with an additional piece of plexi-glass to give a greater surface area for the join, as water is incredibly heavy! FWIW I will also have much thicker plexi-glass at the bottom and top (top with access holes) with plenty of silicone around all edges. Many thanks for stopping by; I appreciate any thoughts you have. I will be posting this project as an 'ible to say thanks for the help.

Anyone know of cheaper alternative material to plexiglass for homemade DDR pad arrows? Answered

What the title says. I want to build a new wooden DDR pad, but this time spending as little money as possible. Plexiglass sheets make a great material for the arrows (see this video: ) but it drives up the cost of each pad by about $25. So I'm looking for a cheaper material that I can cut into squares for the arrows/buttons; it needs to be at least slightly flexible (so it can warp downwards slightly when stepped on) and obviously sturdy enough to withstand stepping, but it doesn't need to be transparent or plastic. Any ideas?

How to back paint clear plexiglass so I can reverse laser engrave?

I'm trying to back paint a piece of clear plexiglass so that I can reverse laser engrave. I'm then going to backlight the piece with an LED panel but I want the paint to be opaque so that the light only comes through the engraved pieces if held up to the back painted side. It will then have a nice look because the clear acrylic will give the lasered piece floating characteristics. I'm able to create this effect using black krylon fusion spray paint, but it just seems to take 3-4 coats in order to block the light out through the paint. I've tried black vinyl, block out sign vinyl and a variety of painted applications but nothing seems to work better than paint. The vinyl applications are also troublesome because the margin for error is too high with vinyl applications as I need the piece to be very consistent on the black reverse side.  I've also found products out there specially made for reverse engraving, but they are extremely expensive, and upwards of 150$ for 24" - 48". I've talked to a couple people that recommended Krylon Fusion normal paint, I'm just worried that if I were to use a roller,  or brush, I'd see the brush strokes from the clear side and it would ruin the piece versus using spray paint, which is slightly difficult to get a consistent piece.  Does anyone have any recommendations for what kind of coating or solution I would be able to use?

Vertical Vivarium

Hello,  About two months ago I finished building my first vivarium. It's a monster at 5'wX2'hX2'd. It has a false-bottom, live plants, anoles, homemade irrigation system, appears cordless, made of 1/8th inch plexiglass and silicone sealed. Recently, it began to leak. The water pooled underneath the bottom panel and remained hidden until it seeped through the plywood it was resting on. I now have a series of buckets collecting constant drips underneath this thing. If I'm going to go through the trouble of emptying the tank and fixing the seal I might as well redesign it so this problem doesn't happen again.  I'd like to make more of a vertical vivarium since I am housing green anoles and they love having height. I'm thinking of recycling as much wood and plexiglass as possible; however, I'd like to avoid as much DIY sealing as possible. I'd like to have either sliding plexiglass doors, plexiglass doors on hinges, or a plexiglass panel held in place by magnets on the front. To fill the vertical space I'd like to have a living wall type plan. If anyone has any tips, guides, or advice for: the front doors, living walls, improving the bottom, or improving the false-bottom, it would be much appreciated.
