Im making an marble air gun just like the one the teach you how to do at sentex.net and i was wondering if anyone could give drawings on how to make the marble gun eject shells? Is it possible on a home air gun? Please tell me beucause it would be really nice if i could eject shells on my homemade marble gun. And not only that but another question as well: Can i make bullets myself from melted tin? EDIT: I just made some drawing and i was wondering what your openion is.

Hi everyone, I was messing around today and came up with a pistol that uses shells. It uses a new shell design, but not a new gun (well except for the front where the shell is held). It shoots white rods about 40 45 feet. I won't be posting this unless I get inspired to make it into a true gun. Picture 1-2 the gun. Picture 3 the shell. Picture 4 the shell in the gun. Please tell me what you think, it only takes a few seconds. Killer~SafeCracker

So I'm trying to make a music box. I bought a 15 note hand crank mechanism I want to install into an 8 inch nautilus shell. I also want to etch the outside of the shell like in the photo. I've never worked with shells like this before and I obviously don't want to shatter it. What tools would I need to do this? What should I be careful of? Anyone with experience working with shells advice would be appreciated. :)

I've got a couple flash drives with broken cases, but the drive itself still works. I was wondering if anyone happens to know if the drive would survive temperatures high enough to harden modeling clay. This would involve about an hour at 300 degrees Farenheit in an oven for hardening.

Hey Guys, I recently made this break action gun. I know it's nothing that new and that's why I didn't post it, but I might if you want me to. If I do decide to post it, I would change a few things. It's not the best looking gun out there and I would probably work on that, but it functions perfectly. It shoots white rods about 30 feet. It has an eject lever to eject spent shells. That's the biggest problem I've seen on other break action guns. I'll explain everything in the image notes so be sure to read them. Tell me what you think needs to be changed. Let me say this gun is more made for fun not war. Killer~SafeCracker

A WWII veteran friend of mine has donated two shells collected on the battlefield in WWI by his father. Following are some photos of the shells: I have tentatively identified them as 20mm HE shells but would like more information, such as manufacturer and probably use. The first image shows both shells. They are 20mm in diameter, the brass casing is 70mm, the steel casing is 49mm and the head is 25mm. The steel casing shows an A and what appears to be an exploding shell. The other two images are of the bases. The letters at the top appear to be B &S; but could be something else. I believe this is the manufacturer's mark. The 18 should be the year of manufacture. I have no idea what the 125 on the left means nor the numbers on the bottom which are hard to identify. Any assistance would be appreciated because my friend, who is now 95, would like more information concerning the shells. Thank you. Roger Laplante

Okay, I know this is going to be weird, but my 4 year old daughter stuck a tiny shell in her ear canal about 3 weeks ago. Its probably 5mm in diameter, flat snail shell. It reminds me of a very small man hole cover. We've seen several doctors, including a specialist, and we're just waiting to see if it will come closer to the outside before having to put her under general anesthesia to remove it. So, my question is there any way to get it out without hurting her? I figured the scientific minds here might know some way to remove it. We've tried ear candles, flushing it with water, olive oil, ear drops, tweezers, even gluing a stick to it (yes really). So, we've tried a lot of stuff with no luck. I won't do anything harmful to my child and won't hold any one liable for suggestions. There just has to be a physics based answer to removing this thing that we're missing!

Question by Loutraki | last reply
In a recent e-mail to Shell employees, Shell CEO Jeroen van der Veer writes:"Regardless of which route we choose, the world's current predicament limits our maneuvering room. We are experiencing a step-change in the growth rate of energy demand due to population growth and economic development, and Shell estimates that after 2015 supplies of easy-to-access oil and gas will no longer keep up with demand."2015 is seven years away and with limited resources and an expanding population we are sure to see more and more limitations on resources we take for granted. Water, cooking oil, and food are also in that list.The e-mail goes on to say that little will likely be done about this situation by any governments until the poop has really hit the fan and by then it will probably be too late. Two scenarios are laid out in the e-mail, Scramble and Blueprints. One is a mad dash towards a solution as we hit the problem head-on and the other is to make a plan now for the inevitable.Personally, I hope for the Blueprints scenario, but I feel like the Scramble is likely what we'll be doing. link

My grandfather gave me this shell casing, and I have been having a hell of a time trying to find out what kind of gun it is from. On the bottom it says "20mm MK 4 I.S. 1944" From my browsing on the internet, I think it might possibly be a US naval autocannon round, possibly from a 20mm Oerlikon gun, or from a British Antiaircraft gun That said, I still haven't found an exact match. The thing that sets this shell apart from the others is the taper. Normally, casings are straight or are tapered in sections, at a much steeper angle. This shell has a simple taper at a very smooth angle. I have not found a shell that has a matching taper. The other distinguishing feature are the small divots around the edge, presumably to help hold the projectile onto the shell. This is rather rare, because usually the projectile stays seated in the shell without any special aid. There is also a weld mark on the side of the shell, possibly from being held in a belt, but I am not sure. I have big hand, so the shell looks rather small. It is actually pretty small for a 20mm shell. Any help in ID'ing this shell is appreciated.

In Most European palaces and castles, it is common to find the ceilings decorated with ornate gilded woodwork and elaborate frescoes. In Brussels, Belgium, one particular hall in the Royal Palace has a very peculiar ceiling that is decorated with very strange items. The hall's ceiling, which has remained unfinished since 1909, was redecorated by the contemporary Belgian artist Jan Fabre. Fabre was inspired by Sternocera aequisignata, a type of jewel beetle of the Buprestidae family, which has a shimmering green iridescent shell. Fabre and 30 other diligent artist armed with a truck-full of beetle shells and glue, transformed the empty ceiling into one bejeweled with a sea of swirling and twinkling green. The team also went to work on the center chandelier in the hall, turning it from gilded gold to sparkling green. As one gazes up at the masterpiece from the floor, the whole mass of shells appears to move as the light reflects from different angles.Jan Fabre calls the the ceiling Heaven of Delight, as a reference to ''The Garden of Earthly Delights'' by early Netherlandish painter Hieronymus Bosch ( a personal favorite of mine). The green shells do indeed add a great amount of energy to the once bland and vacant hall. 1.6 million beetle shells were used. The beetles, which are wood-boring and are mostly considered a pest, appears abundantly in India, Thailand, and Vietnam. They are sometimes cooked and eaten, however their beautiful shells are discarded.LinkTranslated Original

I'm looking for a semi-permanent solution to making a fire pit into a wood fire oven. The shell could be something modified from an existing item or something from scratch. I'm thinking a dome shape similar to a brick wood fire pizza oven would be best, however I would want to be able to remove it so the bottom portion is functional as a fire pit and could also be used as an open pit/grill. It would probably be more on than off, so semi-permanent is okay. The pit itself would only be about 2 1/2 to 3 feet in diameter, so nothing too big. As far as functions, I would have a grill at the top of the fire pit (maybe height adjustable within the fire pit, but that's getting kinda fancy). Then in "oven mode," I would have the grill in and put a ceramic pizza stone on top of it for baking then the cover on top. And perhaps even without the stone as a smoker/meat slow cooker. Ideally the cover would be well insulated to keep the heat in and well distributed. It would also have a cutout or door for putting in bread or pizza (rather than a cover that lifts off losing a lot of heat in the process). I'm not sure what materials would be good, but it should probably weigh no more than 75-80 lbs. (light enough for one strong person or two middling strength people to lift). Maybe an inner dome of some metal with a layer of some kind of flame resistant insulation and then another outer dome of more metal? It would also have to be weather resistant for cold winters. Some assembly might also be good as the individual parts would be lighter, so long as being in pieces doesn't compromise the overall effectiveness of the "oven". I've tried searching for a few things, but nothing has really popped up that fit this description. Any ideas would be greatly appreciated. Thanks!!

If you've ever been to IKEA, then you've probably found that the expensive electronics in the mock-up rooms (TV's, computers, etc.) aren't real, and are just plastic shells.

Hey guys! Well, here is my most recent project, the RSEC (Shell Ejecting Carbine). The title really explains it all, it is a shell ejecting carbine... of sorts. Technically, the definition of a carbine is a gun that is in rifle form, but shoots pistol / SMG ammunition. This gun does not EXACTLY fit that definition, as it shoots blue rods, which is the K'NEX equivalent of a rifle round, but, all the same, I'm gonna call it a carbine. The thing that perplexed me about this gun is it's pin pull-back length. You see, the pin pull-back length on my K'NEX Gun: Reliable (R3) outdistanced the RSEC's pin-pull length, but I'd bet you that the RSEC would get better range, even without shells. I couldn't really tell you why that is, but, more likely than not, it is a result of the barrel. The R3 has a long barrel, which may mess with the rounds, but this, the RSEC, has no barrel (I.E. the rounds are shot right out of the magazine into the open air). Let that be a lesson to us all, K'NEX barrels are pretty much useless (which may be part of the reason why K'NEX bullpups are no good). Features: Great range: 50 - 70 ft. (even without the shells) Comfortable Everything in the gun is well situated (IMO) Nice 'n short, just like I wanted it Heavily modifiable True-trigger operated Good pull-back-length Hand guard Shoots shell ammunition OR non-shelled ammo -The Red Book of Westmarch

When I was a kid I remember every year we had a Popcorn Pinata at Grandmas. I'd like to make one for the kids at Church. And maybe start the tradition agian. All I remeber is it was a big hollow popcorn ball that was actually two half somehow glued together and it was pretty tastey too. I tried once before to guess at how to make it. Heres what I used and the probelms with it. Light Corn Syrup and popcorn two metal bowls and wax paper to lift it out with. The probelms were; it didn't hold it's shape taking it out (so it sure wont hold up to a beating). I'm not sure how I would go about making a loop or something stirty enough to hang it from either if it did harden enough. Also, I remember some years it was impossible for us kids to even crack it. (but the Uncles had fun helping) Any thoughts?

I'm making eight, seamless 15 cm3 cubes that will be translucent and have a glossy finish. They will be lit up (with LEDs, etc.) so the entire cube appears to glow, but there is a base side which will always be on the bottom (it doesn't have to be made of this material.) Sturdiness is desired (they will be in transit at some point), as well as low cost. The solutions I have in mind at this point are: Frosted acrylic/perspex glued together Some form of cloudy resin cast into a single-piece shell I imagine that the resin would have a better overall appearance if it goes well, but it sounds expensive and complicated. The perspex solution may have a less appealing end result due to the edges between each face. Please suggest alternate solutions if you can think of some! Thanks for your help. TK.

I am very new to Emacs (as of the 25th) and I learned that prelude adds some functionality to the program. But, on github where it is available for download the directions seem unclear and confusing to me. I don't know whether or not I'm using Curl or Wget and I don't know how to use them if I am. I tried entering the provided lines as a Shell command into Emacs as well as just entering the text in to my command prompt. For the shell command in emacs nothing seems to happen, and for command promp is gives the "not an exicutable" splerge. I have downloaded the file from GitHub but I don't quite know what to do with it now that I have it. I use Windows XP if that accounts for anything. Any suggestions would be greatly appreciated.

First of all what the hell is that striker made of and second of all what the hell drill bit can get through it, I knew they were tough, I couldn't be assed cutting one with just a hacksaw blade so i did it with the drill as a lathe...
