I would like to drill a hole into he bottom of a 3 quart stainless steel mixing bowl in order to insert a 1/2" brass needle drain cock (and then secure the valve to hold liquid). How do I measure the diameter of the valve so I use the correct drill bit? How do I get the hole centered.? How do I keep the pot stationary? The bowl is thin, how do i keep the bit from ripping the metal?

Hello, everyone! Totally new here.Well, I'm going to buy a pair of 12 volt "eagle eye" LED for a medicine experiment, and I planned to connect them to either a rectangular 9 volt battery or 3 cylindrical 3.7 volt batteries. But now, these LEDs are meant to be connected to a 12 volt car battery. Does the difference of the amperes between each power source (car battery, rectangular and cylindrical) conflict with the LED's functionality, or does the integrated resistor allow me to use any power source without trouble?Here's a picture of said PCB with the integrated resistor, for example (found on the internet), it just reads "300" and I don't know what that means. Sorry if all these questions and doubts are really silly, but again I'm a medicine student trying to make this work and electricity is a really complex world. Thanks in advance, wise people!!!

*Yes, I know, another question involving college and my future life.*I am kind of split between mechanical engineer and metallurgical engineer. They both have some great benefits and trades that I'd love to go into, but it's difficult deciding which would be better for me.I do aspire, no matter what field I go into, to weld and do other metalworking, although I don't just want to weld for people. I know it sounds weird, but I like to take the time to know about what I am working on, and not work at "face value", if you will.So, any mechanical or metallurgical engineers who want to try to sway me one way or another, please do so now. ;-) Thanks,Bran.

Question by PiyushS93
I know BEAM robotics have fallen out of style a bit, but I hope someone is still mucking about with them because they are super cool. I am working on a Miller Solar Engine and trying to find a replacement for the 1381-J voltage trigger. I tried out the DS1817. It was recommended to me by one the technicians at Digi-Key as a replacement for the MN1381-J and on paper it looks like a good swap, but in the circuit it is just not resetting once the voltage drops. I have it breadboarded and I can stick the 1381 in it and it works perfectly. When swapped with the DS1817 it triggers once the top voltage is reached, but then never resets (it just drains forever.) I double-checked the component type to make sure it was just not a miss shipment of the wrong item, but it checks out. And I tried swapping the DS1817 component out thinking that I just had a dud (or 5) but it does not seem to help. Any thoughts? Here are the data sheets on the 2 items. http://datasheets.maximintegrated.com/en/ds/DS1817.pdf http://www.semicon.panasonic.co.jp/ds4/SAG00003CEM_discon.pdf one bit of weirdness I already figured out is that the 1381 looks like it has a different 1-2-3 pin out sequence at the top of the PDF but it turns out it does not at the bottom.

Hello, I am writing because I have a question about a project I'm working on. I've built a gokart frame and attached a 12v 600w motor to it. And I have a Speed controller (https://ebay.to/2KUnnqe) that can handle the amps the motor is drawing but right now the only way i can control the speed is by twisting the potentiometer, and that means I cant have two hands on the steering wheel. So my question is if I can wire this foot throttle (https://ebay.to/2OChMa7) to the potentiometer and if so what wires will go to what wires and will this even work to control the speed.Thanks in advance for any answers:)

I recently found a free website called Kit.com, and as the name implies, it's a website for making kits of the stuff you like and useSo far, I've made a bunch of different kits such as " Dremels & Rotary Tools: All of The Accessories You Need" " My MUST Have Workshop Tools I WISH I Would've Bought Earlier!" (And several others that are organized on my Kit profile page)I think it's a pretty cool website, and encourage everyone to make their own kits of the tools and stuff they use in their projects! If you make your own kits, link them to your Instructables profile page (Like I did with Linktree), and post a comment below so can all see what you use and waste more money on tools we're sure we need! :)They also have an option for embedding the kit in a website which looks really nice (see this, though when I tried it once it looked a bit different), but unfortunately Instructables doesn't support it... (hint-hint!)You can also create an affiliate code, so when people buy through the links, you earn a few percent of the sale, which is pretty cool too!Maybe unrelated, Kit was just acquired by Patreon so if you read this in the future it might not be free. I have no idea. Also, if you're an SEO genius you need to tell me how to make it so my kits rank on Google!Post a comment if you make one!

Hello! Let me give you some insight into this project (Tin Can Turbine). I'm going to school to get an Airframe and Power Plant Cert. (Aircraft Mechanic). I stumbled across this idea on YouTube one day in class and it really got my gears turning. It's purely for fun, and I'm not even sure if I have the technical skills to get it to work. First of all the way a turbine engine works in layman's terms is Suck, Squeeze, Bang, Blow. The fan section sucks air in from the atmosphere, Where it is moved to a compressor section which squeezes the air into a tighter pocket of air; which makes the air hotter and more explosive. When the compressed air is pushed into the combustion chamber, it is more volatile than normal air due to the compression. When you add a fuel (jet fuel, gasoline, propane, kerosene etc...) it will ignite with the compressed air (given that there is a spark to get the fuel vapors to ignite). When the fuel/air mixture is lit the fire will continue to burn without an ignition source due to the explosive nature of the compressed air. And the gas (burnt fuel/air) is pushed out the exhaust. There are blades in the rear of the engine called turbine blades, which are connected to the front of the fan/compressor section, in some cases there are two or three turbine blades, which drive the fan, compressor sections independently. Due to the turbine blades being pushed by the exiting gasses, the engine becomes self sustaining. And through black magic, you have a jet engine!!! I'm going to attempt to construct a jet engine (not a motor!) out of a "tin can". I'm really not going to use a tin can, I'm actually going to use .032" thick 3" wide, and about 6" long exhaust piping made out galvanized steel. It's a lot thicker than a typical soup can, thus willing to stand up to more heat. My proposed fuel source will be propane, because it's cheap, and the I'm sure that I'm capable of controling the amount of fuel going into the engine. I'm not sure yet how many fan blades vs. turbine blades that I'm going to use. Right now I'm in the experiment phase. My blades are going to be made out steel can tops, because there is very little cutting involved, beside the actual cutting and angling the blades. and they fit perfectly into the pipe. As for the fuel delivery i'm going to use a copper pipe that is approx .042 thick and hallow. I'm going to cap the end, and wrap it around the inside of can. There will be eight holes drilled into the copper, which should give it plenty of fuel at equal pressure all the way around the can, equals same heat all around. As for the drive shaft, I'm not exactly sure of what to use for that. I may want to go with something hardened already, so the heat surrounding it won't melt it. (that's the hope anyways) . I'm also not sure of what sort of bearings I will use. I was thinking skate board bearing with the plastic crap around the middle taken out (so it doesn't melt and seize the bearings) and extreme high temp. white lithium grease for lube. This is an experiment and I guarantee myself absolutely no success. But I think it will be fun to try. Questions or comments are more than welcome. Please, if you see any problems with the design, let me KNOW!!!

Hi, Everyone. I am building a carnival game, and I need to know what kind of pump I need to pump water from a 5 gallon bucket into a balloon that is about 4 feet above the bottom of the bucket. The object of the game is to squirt water into a hole that has a pipe connected to it going into the bucket. The water than will get pumped up out of the bucket into a baloon that will end up popping from being overfilled, splashing water everywhere. I was thinking that some kind of submersible pump like this- along with a float switch to turn the pump on when some water goes in it, but I was not sure if this pump would have enough pressure to fill and pop a baloon. Thanks.

I just worked on a Husqvarna 142 chainsaw for a friend. Yes, there are openings in the side of the machine so the Low and High carburetor screws can be adjusted, but a special tool is required, or parts need to be removed from the saw so the screw shanks can be grasped with a pair of needle nose pliers. A special tool is svailable for about $6 US. It fits over the longitudinal ridges on the upper part of the screw shank. I discovered the right size of semi-rigid plastic tubing makes an effective adjustment tool. Just cut a length three or four inches long. Push one end onto the desired screw shank and turn to adjust. The tubing is rigid enough that it does not twist, but turns the screw needing adjustment.

hello, i extracted some lithium metal from some new lithium batteries i bought at a second hand shop really cheaply . ive extracted the metal from one, but now, after placing it under vegetable oil to store, then putting in water, the vegetable oil works too well seperating the lithium form the water, making small lithium combustion reactions very difficult and i really want to show my friends the marvels of lithium on water, so i want to know, is it safe to store lithium in methylated spirits, or some other hydrocarbon that will evaporate away really fast , and not inhibit the lithium's reaction with water, like canola oil does? clean lithium usually combusts when i put it in water , and the reaction is quite fast. but when i put oily lithium in water, the same does not happen, the reaction is slow, and no combustion occurs unless i use my jet lighter.

I want to varnish this birch plywood platform to keep it as waterproof and UV resistant as possible but also keep it as close to it's original pale birch colour as possible. i've never varnished anything before so i've been googling for answers and i'm getting some conflicting information, i've been looking at different clear outdoor varnishes and most claim to protect against UV light and not leave a yellow tint but most reviews say otherwise and some general varnishing info articles claim that clear varnish can't protect against UV at all and i'd need a dark stain which i really don't want. so what can i do to protect the wood against the elements and maintain the colour as much as possible? can i combine varnish with other stuff? i found some clear 'marine varnish' is this heavier duty than normal wood varnish or something?is there an alternative to varnish that will have a similar effect?if i need to modify the platform later, cutting bits out or drilling new holes is it ok to just apply another layer of varnish to reseal it or will it need preparing in some way or some additional step?

Question by Philveo
Copying and rehash are not things often regarded as good for do-it-yourself communities, yet Instructables is currently quite accepting of things that would fit under this umbrella and in some cases even sponsor it. I hope to convince the administrators that new rules need to come into play--particularly with regard to competitions. I'll discuss why unoriginal projects are a problem, lay out the causes of this and present some solutions that the administration could pursue. Copying is a problem for Instructables because making your own example of someone else's creation with no alterations does not advance development at all. In many cases, these copies even infringe on copyrights. In competitions, such as ones on Instructables, copied projects can become popular and even eclipse original designs; this discourages originality. An author might ask himself why he should bother investing time researching and developing a project when he could just as easily locate an existing design and copy it instead. In many cases, the causes of copying can be innocent, such as when a child who posts his friend's favorite paper airplane design (which actually originates out of a copyrighted book, for instance). While innocent, this action still proves unhealthy to the DIY community. There are also less innocent types of copying as well; such as those who knowingly steal creations and post photographs or links to media of creations not of their own design. While this latter type is less prevalent on Instructables than places like YouTube, it still occurs due to embedding. To discourage unoriginality and encourage advancement, Instructables staff should make a few changes to how entries are looked at as far as appropriateness goes, as well as what gets featured or judged a winner in contests. Projects that are not original should be recognized as such. It might be appropriate to outright disqualify an entry or issue it a penalty or rank reduction in judging. It is not advisable to feature unoriginal designs. These sort of steps could encourage people to contribute rather than copy. I hope I have inspired thought in others regarding this. I have talked about the problems of copying, why it happens and how it might be addressed--hopefully it is.
