Hollow shafted potentiometer?

Hi everyone,  I have a project I'm working on which has two halves that are connected using a potentiometer as the axis, resulting in the two being able to twist, changing the resistance of the potentiometer.  The problem I have is that the battery is in one half and the circuit is in the other half.  I have to somehow get the power to the circuit, but still have the pieces still be able to rotate.  I can't have the wires just sticking out of the side because it has to twist, and that would look horrible.  My first thought was to drill a small hole through the shaft of the potentiometer, so that I could run the wires through that, but when I tried to do that, it turned out to be a lot harder than I expected and I now have a busted potentiometer.  I would really like to avoid slip rings of any kind, as they would be exposed to the elements.  Does anyone have any ideas, or any advice on how to drill a nice hole through a steel rod lengthwise?  Ideally I would drill the hole, but if that's too difficult, I'll try whatever. Thanks ~Dudes

Magnetic Field for hollow core?

I am working on a project in which I have to control a small setup at the end of a motor shaft using an electromagnet. The electromagnet needs to be around the shaft inbetween the setup and the motor. So I have used a metallic ferromagnetic spool(image attached) and wound 32 gauge wire on it to make it an electromagnet and put the shaft through it. Since this core made out of spool is hollow, I'm not sure how the magnetic field will behave. I tried powering up the one I made and it' seems to be both attracting and repelling a magnet's pole (edges attract while centre somewhat repels). Anyone got any idea about this?

Wondering what I can do with this hollow cathode tube...

I've got this hollow cathode tube from a spectra aa machine (used for metals analysis). It was supposedly still working - my old boss at the lab I worked at found it and considered tossing it out as they no longer had that AA machine (they had upgraded to an ICP/MS), but knows I collect interesting looking things. Am I right to assume that cathode tubes are quite dissimilar to the variety of tubes used in vintage amps and of no use in that regard? Does anyone know what sort of power I'd be looking for to even get this thing to light up? On the plug at the end of its cable, they posts are labeled A through F, then H, J, and K.

What to use as a pivot? eyelet, hollow shaft, hollow nut & bolt? Help

I am looking for a permanent way to hold together a leg between 2 plastic pieces. I want the shaft that goes in the hole to be hollow, cause i plan to pass something through it. I have attached an image with the dimensions. The leg (center) is aluminum and the plastic parts on either side are delrin. I was thinking of eyelets, a shaft or a hollow nut and bolt with thread fastner, but I think all will have to be custom made. I want the fastner that holds the leg and the plastic together to also help in restrictive rotation so that alittle force is required to rotated the leg about the hollow pivot point (the shaft). Does anyone have any ideas of how i can do this or any better methid? Thanks for all your help in advance.

Creating hollow, clear mold. What materials?

I'm trying to create a Metroid from the titular video game series but I'm not sure of which direction I should go. As you can see, the top (i''ll call it the "head") is semi clear but contains a nucleus within it. So far the only method I can think of is with clear resin. Issues though are that I dont know how to leave an empty space for the body to fit within the head and I dont have a pressure pot available. I've never created a mold before and my only experience is clay sculptures. What methods could I use to create this? All I have to work with is my garage and some clay at the moment and although I'm willing to go out and spend some money, I wont be buying something like a $300 pressure pot.

The Moon - What do we really know and what is possible?

If we look up then seeing the moon is the most normal thing to us there is in the sky.But did you ever wonder how it actually got there? ;)Theories are out there by the lot, including those from real scientists.One of the most common is that it all started by catching the thing and that all was perfect at the time.Over time the orbit then stabilized.Other theories include that formed when our planet formed..What they all lack is what is common and true for all other moond out there: These rotate.According to science an object the size of our moon would need to rotate to maintain a stable orbit.No one told this to our moon, so it just stays in a stable orbit anyway.The only other accepted theory, that funny enough never mentioned OUR moon, is that the center of mass must be facing the orbiting planet.Now theories can run and wild if you let schientifically people loose on a subject.Official NASA data obtained by monitoring equippment on the moon supports the theory of the center of gravity.You see, sesmometers recorded "moon quakes" but also the impact of burnt rocket stages - the later were dropped on purpose.At first everyone agreed the equippment must be faulty but going through it again and again confirmed all works fine.So what got them so exited that was never officially made public?You see, every thing with suffient mass will create a sesmic shock on impact.On earth we can located the source of an earthquake or even explosion quite accurately.Same happened on the moon only with one difference to earth.Every impact caused a ringing effect.Like a bell, the soundwaves and shockwaves traveled through the moon for very long times.An early explanation was that the moon is made from really hard rock or that it might even have a metal core.This was rendered useless once the actual mass was calculated and it turned out the moon would rip us apart while spinning around us.The term "hollow moon" was born.Another interesting thing happens when you try to track down what equippment was left on the moon during which specific mission.Everything up there must have been installed at some stage.For some things though it seems there is no record when or where exactly something was left up there.Then there is the thing with the interviews...If you check the fuzz about the first moon landing then back then you couldn't help yourself but got exited as well.None of the three astronauts however appeared to be at least a little bit exited about going where no man has gone before.Somehow like visiting Iceland for the first time only to realise someone was there before you already.But it was the moon, not some easy to reach island...And while up there we did not see any exitement either, like fully staged and planned ahead.Like a not so 100% school rehersal.Claims that it was a fake and actually filmed in some studio have been verified to be false - they really were up there.After they came back two went silent and refused any interviews about the moon.All three though never spoke about anything we did not see on "live TV"...All the missing segments, the drop outs, the silence during communications...The money...Apart from the Pentagon making a disappearing act of 6Billion US, the already planned and staged moon missions were cancelled with no valid reason at all.One mission already ready to go to the launch pad, crew fully trained and briefed.Two more ready for final assembly.Official reason back then was "We have been there, it is time to explore new things."Almost the same statement was made by Obama a few weeks after he claimed "We will go up there again!".If you take away the costs for the abandoned missions then the money blown up to the moon has a huge difference to what can be tracked back.The lost sum equals out to about 8 more moon missions plus tons of state of the art equippment (back at the time it was state of the art).If you add what the Pentagon lost we are close to 15 more missions.The now...A few years back a lot of previously declared top secret documents have been released to the public.What was a good idea however turned out to be a bit too much.Quite a few documents were included that provide missing links to "incidents, missions, money spent"...Within these piles were documents indicating that space missions of the same extend as the much later moon missions were made.Same rockets, similar crafts, same requirements for water, food and oxygen, some though with just payloads of oxygen and water.Mind you though the documents speak from proposed options and not planned missions.And none of them had any exploration within it, just deliveries if you don't mind the comparison.Those documents about the ringing of the moon and how this would impact on the things we assumed to know about the moon were in there as well.What is really interesting though is what came back from the moon.None of it actually indicate that there is suffient ressources up there to justify mining.Funny enough exactly is planned on a military style.Seems fair enough considering the military can provide the best people for such a hard job.Some normal miner might have no problems getting under ground every day but knowing he is on the moon and might never make it back is another.With all the probing done that we know of you would assume the planned mining operations would be in an area rich in minerals, metals or at least something to generate fuel or oxygen.But no, it is planned to happen "on the dark side" and in an area that appearently was never explored in other ways then taking a few blurry pics while flying around the moon.However, both Russia and China claim to have been very close to this area long before details about the mining became public.And that brings us back to the past and what astromauts stated or to be precise refused to confirm or deny.In some videos we can see movements in the background.In several adio stream we hear the comments to what happens in the videos.If there is light moving around then it does not matter that is blue.You just wonder what it is and where it might have come from.Imagine the surprise if then in other videos you hear things like that the lights are back or that steam comes out of the moon like a gysir.There were official explanations for the first sightings made by the normal people when watching those videos on the NASA websites.Soon after the videos disappeared from the servers.Copies were made by the curious and quite a few videos were identified later to have contained "sightings" as well.Some even show what appears to flying machines with great manouverbilities.And if you take the high point of the happenings then it is also the same time when it was decided that we actually have no real interest in the moon.Astromauts later denied to have ever made any comments like that they are being followed or "escorted" by another craft.And the same Astromauts many years later still refuse to deny or confirm that what we could see and hear during their mission videos actually happened.Don't get me wrong but if the deny it then it just means we all saw some refections or such things.If the confirm it then we know something was out there with them.Doing neither usually means what we saw is ture enough to deny any knowledge about more details.Why then the sudden interest?Trump wants to get up there, military mining, private companies not to forget China.If there is nothing at all up there then why would they all spent money that could provide a much better living for those with low incomes?Even if it would be just for new schools and hospitals the money would be better spent if we trust the official claims about what is up there.The not so official claims....We already know NASA does not want to come with an official explanation why the moon sounds and reacts as if it would be hollow.Same for any video, audio or picture evidence indication there is sturctures on the moon or activities.Here is some of things that other people of great knowledge and with nice degrees under the belt say could, might or even is true about the moon.1. We have no evidence that the moon was always there, only what we have in record throughout history.Some claim the moon would be an artificially created structure.Indications of techonlogically highly advanced civilisations before us are there.And mining out a tiny planet and placing it in earths orbit is not far fetched if you consider higher technology levels than what we currently (officially) have.2. The satellite claim.Like the Death Star our moon could be an artifical satellite placed there for a purpose.What speaks for that theory is the impact craters on the moon.If it was never spinning or better rotating around all axis then a lot them would have been impossible.A crater always shows to some extend the direction of the impact.And on the moon they all apear to be direct and straight hits only.And even at some proper angle that against physics did not create a corresponding crater: Our plant would have been in the way.Officially it is claimed though that there would not be much of a directional crater because of the missing atmosphere and all debris settling evenly.Debris however does not explain the deformation from an impact at an angle.The satellite claim would also explain the missing depth in the craters.By the size of the bigger ones the crater should be much deeper and as said show some direction.If however the rocky surface landed there over time or is just the remaining natural hull then the craters could no go deeper.No advanced civilisation would design a stationary satellite that get a hole as soon as some big space rock hits it...3. Undocumented missions.If claims are true then we have been up there a lot more times than what our history lessons tell us.Tiny probes to analyse things, send data and so on are a thing not the the USA did.If you explain the reason for collecting seismic data by wanting to document an impact of an astroid then it is a joke.Sure it would be possible but what could we learn from the data?Nothing unless you consider that in some unoffial missions drilling was attempted on the moon.Sample collection to evaluate what is in the ground of use for future missions.Some documents now claim that all these attempts ended prematurely.Drills failed or broke, drill heads failed to go deeper and upon inspection were totally worn out.And all seemed to have happend at around the same depth.Although there is no atmosphere on the moon - if you stand on it you would be able to feel vibrations of the surface.Something astronauts would have felt during the drilling.And you can feel the difference between a vibration ending by stoping the drill and one that keeps going for a long time after...The dark side is visible in quite a few school books.Looks like the front with the brightness corrected just with different craters.Ever bothered to scan these pictures in and use some software to find matches to craters on the front of the moon ? ;)Anyways, those images show us the moon as near perfect sphere.What they don't show is how the images were actually made.They certainly did not use massive search lights from orbit to provide light for cameras.Means other sources were used, like IR, Radar, Microwaves and so on.Like we found the ruins of old civilisations by using satellites that can "see" through the forest and soil.And with that it would certainly be impossible to create such a nice and detailed image like we get from the front side.If some is edited, then why not all of it...And if all those missions we don't really know about also landed on the dark side it would explain a lot of things.All sightings seem to have disappeared to the dark side.And all leaked informations about previous missions before our first landing idicate the interest in the dark side was actually huge.They all ended though with one mission report claiming to have spotted lights on the dark side.Moving and stationary and when trying to get a better look by adjusting the orbit for the next round those lights were all gone.But audio recording indicate that from that moment on the astronauts were no longer alone and followed until turning back to earth.Several attempts seem to have been made to land near sightings on the dark side.Those where the astronauts returned home the never were the same again.Documents claim long treatment in mental facilites or suicide.The official missions appearntly started with the backstory of exploring.Some now claim it was attempt for a peaceful presence that still was not tolerated.4. Stories from involved companies.Even if NASA builds a craft themself they still need the corresponding supplies.And for a lot of things they are made outside by independent companies and contractors.Trying to track down early space mission again seems to confirm all claims about previous missions.The amount of materials provided would otherwise mean NASA actually crashed the majority of things right after take off without anyone noticing.5. Launches...So far all claims about previous moon missions or just secret ones were denied.I call this "plausible deniability".In all statements it is refered to the official launch sites.Things like being in public view and so on.What is not that commonly known is that there were a lot of capable launch sites available.After all big rockets have been tested in secrecy since we had the first.The claimed landing of the chinese started a big conundrum.At first the US claimed it never happened because there was no rocket that went up.Images prived by the chinese however clearly indicated the opposite.Not much later it was noticed that a few launches might have been misinterpreted as missle tests....What does that really mean?Quite simple: The surveillance is not perfect if the other side insists that it happened.The plausible deniablity is gone.If the US was "forced" to confrim they actually noticed the launches then it also means the chinese claims about the US doing the same could be true as well.And wasn't it a very important thing during the cold war to know when, where and why the other side launched anything?The silent agreement not to go up there again was broken many times...And although most if not all of these mission ended in orbit only it makes you wonder.What would be big deal even if all claims and conspiracies would be true?A hollow moon would defy what we know about how the universe works.With that it would also contradict some of solid laws of physics.So we need(ed) proof.Assuming we had that for a long time already then it leaves the big question of why it is hollow.Natural or artificial.Nothing natural would make sense so we investigate further.And if people still claim that they can use their little equippment to every now and then hear transmissions from the moon...Sure some things up there transmit data all the time but they do so on common frequencies and not in a range that is and never was used for long distance communications.The interest in the mon came back with our modern technology.We have watches with more computer power than what was used for the old moon missions.Materials and manufacturing methods that provide much safe crafts and space suits with a fraction of the weight of old designs.And we have new means of taking more or less limited energy up with us...We are prepared so to say.No matter what really is up there, no matter if it natural or artificial, just the fact that the moon is hollow changes our views on a lot of things....What do you think would be the best explanation for the data showing the moon rings like a bell?

How to compress air into a hollow solid without a valve?

Hi  Really need some help with this one, have searched everywhere but cant seem to figure it out. I know there is probably a very easy solution i'm missing so please help. Basically I want to compress CO2 at around 80 psi into a hollow metal. I have drilled a micro hole and created an opening (about 2mm radius) into the metal. My problem is after I compress the CO2 in there how do I remove the compressor nozzle and seal the hole without the CO2 escaping.  The metal is small and there is no place for a valve. Is there such a thing as a self sealing removable valve? Or could I use a valve  with two openings and pump liquid metal (that would than solidify) and seal the hole so I can remove the compressor?

How can I make a hollow, see-through sphere? Answered

This is for an adaptation of a lamp. What I want is to cover the bulb with a large (little smaller than a basketball) sphere, so there will be a hole in one end. Light obviously needs to be able to shine through. My first thought was a resin of some sort, and a quick search led me to epoxy resin. Is this see-through? Can colour be added? Any other ideas? Some early thoughts: - In an inflated balloon, inject liquid. Rotate, thereby distributing fairly evenly, until liquid hardens. Cons: How long do I have to rotate this balloon? What if it pops!? (Could use a hard container...) - Double boiler: Use two similar bowls, small inside larger, fill in between. Cons: How to get it even? Smaller bowl would float (weigh it down...) Not even close to a sphere With your suggestions I'll do a few trials, possibly put out an instructable if something works. All suggestions are welcome (even if they deviate a little). Thanks!

How to tighten a nut on a threaded rod from the side, through a hole in a hollow tube?

Picture a threaded rod, with a hex nut on it. The rod is inside a hollow tube. You move the nut down the rod by inserting an outside hex wrench into the hollow tube from the top. But what if you only have access to the rod from the side, through a hole in the tube (which is fixed and can't rotate around the rod)? Is there a way to tighten a nut down a threaded rod from the side through a hole in a tube? Context: the application would be a grip for a fencing weapon. The base of the blade of a fencing weapon turns into a threaded rod (the tang). The bell guard (metal disc to protect your hand) has a hole in the middle, and is inserted onto the tang. The standard grip is a straight tube-ish thing (usually solid except for a hole the diameter of the tang). You stick the tang through the central hole in the grip. Then you stick a nut on the end of the tang (which just extends beyond the end of the grip) and tighten the whole assembly down. Some special grips are curved, which means that you have to bend the tang in a curve to match the grip first in order to fit it onto the tang. Another kind of grip is straight and hollow, with a plate with a central hole over the end butting against the bell guard, to give the nut a surface to press against, and the tang is cut much shorter than the grip, and you tighten the grip with an outside hex wrench from the back end of it, as I described initially. The advantage is that a shorter tang weighs a lot less, and the weight savings can be really good in fencing. I want to combine the advantages of these two types of grips- a curved grip, which is hollow and lightweight, with a tang that is shorter than the grip itself. Obviously, it would be impossible to tighten the hex nut through a curved grip, hence my question.

Does anybody know what the object in this photo is?  The thing was in a box of stuff I got at an auction and neither myself or several friends know what it is for. It is 6" long and made of metal (I think it is brass) and is kind of heavy in my hand. The tip on the smaller end of it unscrews at the narrowest point and reveals a hollow shaft. Thx for your input!

 Just as the question is. I need to create a cone in Google SU, which I can do. But then I want to make the cone bend slightly. Is there any easy way to do this? And, can I make the cone hollow?

What is this? Answered

I found this in the black sea, and I have no idea what it is. It feels kind of like a bone, is a bit thicker than 3 peices of paper towards the wide end, and has a hollow tunnel going through from the small end and opens out in the wide end (see diagram). If anyone has any ideas, please tell me.

How to dismantle bicycle hub motors?

I need to open up the hub motor to repair the wires which have been ripped out of the hollow axle. I am reluctant to use force to separate the motor shell and it does not seem to want to separate after removing the allen screws. Which side is the best to remove? It is an ebikekit 500wat motor.

How do I make a drum from a bongo base and an unshaved skin?

I have a gorgeous hollow base of an old bongo and a very hairy piece of skin that is supposed to fit it. I'm not sure how to put them together and what other parts I need to make a functional drum, not to mention shaving the skin. Any help would be appreciated.

How can you tell if an old water well has been filled in or just covered up?

We know this space used to hold a well, and I'm hoping they just covered it with concrete and it's hollow under the floor, but I don't know how to proceed, just start drilling? any other ideas?
