My paper slicer got warped in a hot car (16"*16" plastic platform with bladed swing arm). Can I un-warp it in my oven? Answered

The same day a lighter wrapped in leather exploded (ripping through the leather), a credit card got Dali-clock-afied, and... so on. the paper slicer is made of thick hard plastic, more like pvc than rubbermade... I was thinking I could set my oven on low and put a damp cloth in a sheet pan and then put the slicer on top of that. What do you think?

Am I using this guitar humidifier correctly? Answered

I recently acquired this Planet Waves Acoustic Guitar Humidifier, and on the package it says no leaks because the holes are on the side. I can only store my guitar (in its case) on its side, so one side is facing downwards. I am putting in the minimum recommended water amount, but i am still worried it will leak. Will it leak? Will I have to store the case laying flat? I really don't want my new acoustic to crack or warp, but i also don't want it to collect water, as this will mess up the wood. Please help!!!

Reshaping Rondo'ed pepakura items? Answered

I've done some digging, and I keep getting mixed answers on this. I have a pepakura helmet I have been working on, and recently, I had the back end of it warp on me. I applied rondo (which is roughly 70% figerglass and 30% bondo) It warped while I had it sitting in my car on a rather hot day, so my hopes for fixing it are high.  However, I have already taken a heat gun to it (which did make it very flexible) to reshape it. However, it always returns back to it's original misshaped form. Am I just no applying enough heat to it? Or have I basically accidentally created a memory material? Thanks in advance!

As true afficionados may recall from the original Star Fleet Technical Manual (pictured), element 114 is dilithium, used to regulate the matter-antimatter reaction for warp propulsion. Unfortunately, with a lifetime of just a few hundred milliseconds, it's unlikely that crystals of element 114 will be produced any time soon.

Phenolic discs for whimshurts? Answered

So recently I found a webpage about someone using Phenol for a rotary spark gap for a Tesla, I had never heard of this material and don't know too much about it. For a while now I have wanted to make a whimshurst that is larger than the one I currently have (bought online, a gift from my family) but with my current one i have an issue with the acrylic discs not only not being balanced but also warped causing them to start vibrating on their shaft making it harder to turn the handle. I figure that because every piece of acrylic i have ever worked with has been warped that is would be best to find an alternative. My question is, would it be easier to keep phenol flat and balance or would it be best to stick with acrylic? another thing im curious about is this a material that would even work for this application? Lastly i would like to say that i did try doing a little research on this and didnt come up with anyone trying it for this purpose, i know that in some cases static can act a little differently than normal high voltage arcs (say, from a microwave oven transformer) which brings me to this question. P.S. im not sure what category this should go in, if anyone thinks there is a better one let me know and i will change it.

Fight Simulator

I just had a great Idea last night. Okay, I think we've all seen those $250,000 homemade flight simulators built by people with just a wee bit too much time on their hands (like anyone who goes on instructables). One of the main reasons these are expensive, other than the computer themselves, is the fact that there are multiple LCD screens surrounding the pilot. These things cost a few pretty pennies, so this is where my idea comes in. The first thing you would need to do, would be to arrange some semi-opaque plastic panels where you would usually have the LCD displays. They need to be opaque enough that you can't see through them, but clear enough to let a good bit of light through. In other words, they need to be translucent, not transparent. The second thing would be computer software. It needs to be able to totally invert your desktop display. You could do this with hardware, but it would be a waste of time and materials. Connected to your computer would be a digital projector, which is where all of the magic of this project comes together. You run the projector through a prism (what kind, anyone?), to slightly warp the projected image. You need this warpage (is that a word?), to counteract the different angles of the plastic panels. The projector is set up in front of the "cockpit," projecting its inverted, warped image at it. You can see the images on the inside, because you chose the correct opacity, right? The hope behind this idea, is that it is much cheaper to have 1 digital projector, than it is to have multiple LCDs. Thanks! MDJ

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?

Is oogoo (DIY Silicone Putty) Oven-safe?

Hello! I have a question for people who use oogoo, or generally DIY silicone molding putty made from 100% silicone caulk. I want to cast oogoo molds of lego bionicle masks with polymer clay, but my issue is I need to keep the clay inside the mold in order to prevent any kind of warping, as most of it is spread a little thin (1-2mm thickness) and I don't want to end up warping it even in the slightest. Is oogoo or cured 100% silicone caulk oven-safe as long as it's within the specified temperature range? (I already know most DIY silicone putties aren't food-grade.) The silicone caulk I'm using is GE all purpose silicone I, mixed with corn starch, acrylic paint, and baby oil. The back of the tube says that it should not be used on surfaces that will exceed 400F/205C. The polymer clay I plan on using is cured at 110C, so I don't think it'll be a problem, but I'm worried exposing the silicone caulk mold to high temperatures will cause it to release some harmful chemical compounds. I looked up an MSDS sheet for GE silicone, and they had a generalized one stating exceeding the maximum temperature will cause the release of formaldehyde. Since I plan on baking these in our kitchen oven, I wouldn't want harmful chemicals contaminating a space where we cook our food. Also, if baking isn't an option, since the polymer clay is spread thin, and cures close to 100C, would curing it in boiling water be an option? (That way any water soluble chemicals would remain contained while the clay hardens.) All help is appreciated!

Heated print beds - are they overrated gimmicks?

For years now I use my old, trusty Mega Prusa with the bare basics in terms of hardware. But basically every new printer out there comes with heated print beds and most users "upgrade" to one to get better quality prints. So I started to to check the reprap forums and other websites to find out why a heated would be a "must have". Quite a simple task you might think, but not so for someone who prints every material on a cold bed with success... What are the official pro statements for a heated bed? 1. Better bed adhesion of course. 2. Less warping of parts. 3. Far less problems with layer seperation. 4. Better print results. And of course there are a few more but not worth listing them. Why do I think most of the four statements are actually unrelated to using a heated bed? Bed adhesion is a matter of print material and surface of the bed / bed preperation, like tape, glue and such. If you filament peels off a cold bed with no adhesion at all it simply means the surface is either unclean or unsuited for the print material. Warping of parts happens because the material shrinks when it cools down, a heated bed is only able to keep a certain height of the print warm. Higher prints won't have any benefit in terms of better layer adhesion with a heated bed. Same goes for seperating layers. Unlike the common believe a heated bed does not fix this problem - it only masks it! Layers seperate because there is not enough bonging between them. This can be due to insuffient extrusion width, too high print layers, wrong print temperature and of course wrong z-axis stepping and wrong extrusion multiplicator. And how good a print comes out of your printer depends on a good calibration and proper print settings - again a heated bed only masks problems ;) Ok, so heated beds are nonsense, right? Well, wrong again ;) They take a lot of worry out of the daily print life to start with. Especially prints with big foot print will benefit, although PLA should never be a problem on a cold bed. If you print long parts in ABS or even Nylon you can have a hard time forcing the plastic to stay on the bed all around the print. A heated bed, with the right settings of course, can make sure your print keeps the shape until it is high enough so the bottom part won't be affected by shrinking anymore. My opinion on how to get the best results... Manage to print on a cold bed first! Smaller parts don't need a heated bed anyway, so use them to improve on your skills of finding the perfect bed material / coating! You will find that once you have really optimised your printer and settings most parts won't need a heated bed anymore. Once you are really happy with the result of smaller prints on a cold bed try something bigger and pay close attention to any problems on the way. For example a big print might start out perfectly but after about 5-10mm of print height you see the part starts to warp and slowly peels of the print bed - especially long parts or thin areas are affected. The infill also affects how a parts reacts during the cooling, so try the same problem print with solid infill as well as only 15% infill to compare - you can stop the print once the problem is identified, don't waste filament. Now comes the magic of the heated bed... You want the temp as low as possible but still high enough to prevent the warping! Why go low if high would help more?? Simply said: If the bed is too hot the part stays soft for a long time, which can badly affect layer bonding and shape. Imagine you squish the plastic on an already "hard" layer - the plastic is pressed flat to be within the set specs. Now if the the layer is still too hot and soft the plastic will push the lower layer in - which of course will expand outwards. So the layer can actually end up to be lower than it should be - layer will still peel ;) Start with around 50° C for ABS and turn the heat down gradually every 10 layers or 25 if you print really thin layers. If the part still prefers to warp go 10 degrees higher. But again: If the stuff would not stick properly on a cold bed work on that first! How do I print on a cold bed and claim it works fine? To be honest, with a lot of time spent on trying, calibrating and finding the right "magic" to put on the glass to make things stick. Nylon, if the part is big, can still be a frustrating task unless cardboard or Bakelite is used but I still prefer the glass bed. I no longer bother with tapes as it can be costly and I hate changing the entire setup just because I use a different material ;) As said, the main key is a proper calibration of hard- and software! If your prints look messy and you spend as much time cleaning your parts as printing them you know what I mean ;) At the moment my "bed magic" is a clear craft glue with methanol as a solvent, mine is from Aldi but similar products can be found in every craft store. The bed is sanded with 600 grid diamond blocks to be as flat as possible and to provide a bigger surface area for the glue. When mostly printing Nylon is first clean the bed with alcohol and put a layer of plastic primer on it before re-applying the glue. With the right temp settings this glue surface can be reused several times with increasing bond to the part. Once the glue start peeling off the bed it cut the area clean and apply another coat just in the spot. A single bottle of craft glue, diluted down by 20%, lasted now about 3 rolls of filament - not too bad for a 2$ investment LOL Seriously though, squeeky clean your glass bed using alcohol and / or acetone and play with different types of craft glue. You want the stuff that is clear and uses either methanol or ethanol as the solvent, don't bother with water based glues! If the glue sticks well to your part but peels off the bed easily try a layer of plastic primer on the bed first - do this outside! However, if your printer is only capable of using PLA anyway you might not want to bother at all and stick to tape ;)

Laser power for thin aluminum? Answered

Here's a question for you laser cnc builders out there, how much laser wattage would you need to cut really thin aluminum? Like, only slightly thicker than grocery store aluminum foil. Very thin. This cnc machine would be used to cut custom theatrical gobos (GOes Before Optics) at home. Normally, when we need a new gobo design, we build one in Adobe Illustrator and send off the design to Rosco or some other professional cutting company. But this can get pricy, and can take up to a week, so if one gets messed up during tech week (they do sometimes) we have to cut a new one out by hand. The results are not spectacular. The gobo doesn't have to be mechanically strong, and they don't warp inside of a 525w fixture due to the cool beam. You could in fact use foil, but that's a little too thin to be useful. Any guidance would be appreciated.

Hard disk platters all the same? Anatomy??

Found a broken HDD of 1 Tb today. Always good to take apart for the magnets. The platters were 'slightly' warped; must have been thrown around... The highly reflective platters can always be looped on a string, to chase away crows from my garden.  By now, I have several dozens of old platters.  I was thinking, apart from practicalities like dust and gentle handling, could it be possible to just substitute the platters with  other (old= much lower capacity) platters?  The 1 Tb mechanism, including the heads, would want to format the platters for a Tb amount of storage I assume. If the platters are mechanically identical (I notice they don't have a standard thickness), could this work?  Does anyone know what alloys are used, are they coated, with what??? I see no attraction when I hold a supermagnet to it, but there ought to be some kind of magnetic carrier on it.... The shine on the platters might suggest some exotic metal coating; palladium or something like that....???

The design is, 4 buttons, 2 hold up to 10 IR codes, and 2 hold up to 10 RF.They also all each have a sound effect when pressed 2 times.When held down, it enters programming mode, RF and IR, cloning the button pressed on some other remote.When pressed 1 time, each button will execute every code programmed on it (IR or RF buttons)IF you can help and need more info to help me, if its something you can do, please contact me through a email.MORRIS2896@GMAIL.COMKind regardsbutton 1= up to 10 IR code store, and double pressed = FX warping sound, with power LED torch button 2= up to 10 RF code store, and double pressed = (5 sec delay) FX futuristic alarm. button 3=up to 10 IR code store, and double pressed = FX searching bleep sound, fast to slow occurring button 4=up to 10 RF code store, and double pressed = FX mine scanning bloop

Cutting PVC Pipe - Lengthwise for guttering

Ok, here's one I thought I'd throw open to the masses.... I'm knocking off the last of a fully automated self-sufficient watering system that runs completely off grey/rainwater. However, the coke can guttering is not working in this position as it has previously :(  I was thinking of using PVC piping, cut lengthwise for guttering. However, I'm working out the logistics of cutting it. It can't be cut directly in half - this would be too shallow to catch the runoff from the chicken shed. and funnel it down to the tanks, so I'm looking at removing a chunk of the top.  And I also have no table saw. Wheee. What I do have Dremel (x2) with associated cutting wheels Jig saw (With associated plastic cutting blades) Circular Saw Mitre saw Hand saws (tenon, crosscut, hack, pruning, etc) So, here's one that I'm throwing open. With the tools I have, how would you do it?  I'm leaning towards the dremel, but there would probably be issues with maintaining a straight line (not that I care about some warp, it's a gutter)   Ideas? *EDIT*  Ended up using a jig saw with an acrylic cutting blade. Worked a treat.
