Question by the troll king 324 | last reply
I came up with this gun design a year or so ago. I think the idea for such a wide barrel has been done, like the bug-squarish one, "Special munitions" or something. Even this use of gray rods has been done as a grenade launcher- but never with a trigger. The usefulness would be to use as a shotgun, of course, or fire those little black circle things. I've taken this apart some time ago, but it could be rebuilt. I realize the wide ramrod tip would seriously decrease power, but it is a less piece-consuming version of the barrel seen on the previously mentioned "special munitions" (or something) gun. Does anyone think this is valuable?

Question by kellyleighg | last reply
Recently I was browsing instructables and noticed that there aren't any 'ables on how to figure out what size of DC powerjack one has or even for that matter how those barrel power jacks are measured. One of the major things the DIY Laptop Repair guides overlook is how to identify which DC Jack you have so you can replace it. Most laptop DC jacks don't have part numbers unless they are from a main distributor like DELL. I've been reading a lot of conflicting information as to what really matters when your trying to find a replacement connector component. Some mention barrel length as being important whereas others focus on the inner and outer diameter. It sure would be nice if someone could write up an instructable on how to correctly identify these and what is important when looking for replacement parts like these.

I was trying to design a new knex barrel and saw i had an excess of roller coaster parts. So i made a long plain straight piece of track and just attached a rubber band to a cart then the front of the track and it had so much power because of the zero friction barrel. So i was wondering if we could form this type of barrel into a new breed of knex guns. Comment if you have ideas.

I was wondering where to find those multipurpose metal barrels like the ones you find conveniently scattered across landscapes in first person shooters. They also seem notorious for holding toxic waste in movies. I was thinking it would be at some kind of surplus store. Can anyone help?

Where can I purchase barrels for a floating dock that are priced reasonable? I live in the country and don't have or know anyone to try to pick up barrels for free. The prices are all over the place for plastic ones, so I thought someone who purchased them might give me a heads up where to purchase them. email@example.com

Questions for you scientific types. Would this work: I have a 3,000 gallon inground pool and no heater. If I took a barrel, stuck it in the shallow end just a half inch above being totally submerged, and lit a fire inside it it would it work to heat the water around it and eventually heat up the pool?

For anyone that has or is thinking of building my M14. For those that have built it, you probably may have notice that the barrel at the end does go off at a bit of angle. Luckily I happen to rebuilding it again today and that problem has been fixed. As shown in the pictures, you simply take out the green rods on both sides and then push the orange connectors forward, add a rubber band and the problem is solved. I will include this pictures in the instructions https://www.instructables.com/id/Knex-M14-Instructions-1/. Thanks to those that left a birthday comment in my 21st birthday forum topic, really appreciate it.

I am looking to start my DIY water collection system, but the key for me is to find 3-4 55 gallon plastic drums for this project. I located someone on craigslist selling several drums for a very reasonable price. The question I have is, should I be very concerned that these plastic drums once contained various car washing fluids? Can these be effectively rinsed out? Will my garden be severely impacted by this?

Twas bound to happen - so why not open the new year with a new high?http://money.cnn.com/2008/01/02/markets/oil/index.htm?postversion=2008010212U.S. crude for February delivery jumped $4.02 to $100 a barrel on the New York Mercantile Exchange before slipping to $99.42. The previous trading record was $99.29 set Nov. 20. Oil prices ended 2007 by gaining nearly 60 percent for the year, the largest jump this decade."This market is really gonna fly," Ira Eckstein, president of Area International Trading Corp, said from the NYMEX floor.In Nigeria, bands of armed men invaded Port Harcourt, the center the oil industry Tuesday, attacking two police stations and raiding the lobby of a major hotel, The Associated Press reported. Four policemen, three civilians and six attackers were killed. The Niger Delta Vigilante Movement claimed responsibility for the attack.At 2.1 million barrels per day, Nigeria was the world's eighth-largest oil exporter in 2006, according to the U.S. Energy Information Agency.Furthermore, the auto manufacturers are saying the new CAFE standards (35mpg for cars) are a very expensive goals. Mind you, there's cars 20+ years ago that exceeded this standard (CRX got in the mid 50mpg range).Futurama did elude to $100 per gallon of gas in New York city by 2012... How could they be wrong? :D

Okay I have not built a cannon yet as such, as I am going to make my first one awesome but I've done some research and found the golden ratio for efficiency for chamber-barrel size, assuming the chamber is always the same volume a chamber is 1.6, now I'm guessing a bit from now on but it seems that that maximum efficiency is approximately 1.61803399 or the golden ratio that keeps appearing in our world, I just thought you guys would like to know for the design stage as this is what I'm going to be using when I make my gun. also is it worth spending extra for a high flow blowgun over a normal one for the pilot valve to my 1" sprinkler or wont it make a noticeable difference P.S. if my calculations are wrong please, if you know more ( I'm only 13) please correct me. I have worked this out from pneumatics, not combustion's or hybrids. expect to see my gun soon!

This came up in another forum, but I heard the report too.... So today, there was a broadcast on NPR (yes, I admit that I listen to NPR :p) about a $100 per barrel crisis.... If you didn't know, a barrel of crude goes for about $93. Personally, I don't think it will cause a crisis - it's not as if it's going from $30 to $100 in a week. However, seriously, are the masses comatose? It's not like no one has been warning them of this - and the consequences nowhere near sustainable living. Arrrrr.... I've been saying it for awhile - if we don't regulate ourselves, nature is going to take the kind liberty of doing that for us (and that won't be pretty). Soylent Green anyone? I mean, I recently read that the average American will consume about 500,000 gallons of water per year... whereas some of the Nordic countries, consumption is around 17,500 gallons per person... By the way, the US has a very limited water store supply :/ US has 5% of world population... 25% of world total CO2 emissions. China, for example, has 22% of the world population - but only 15% of the world's CO2 emissions.... US has 5% of the world population - and 29% world CO2 emissions from fossil fuels. (china 14.5) What percentage of companies are considered sustainable (by Dow Jones sustainability index) in the US? A measly, 19.8% (UK: 68%).

Thanks to CJ81499 for finding this out. Well, he managed to make my gun shoot like it had a rifled barrel (FYI, a rifled barrel spins the ammo horizontally for more areodynamics), so now I have the first knex gun with a rifled barrel that shoots well. www.instructables.com/id/SWVUCGGG2HE1A1C/ More details in the link.

Hello,I wanted to start my own backyard composting and I looked at a instructable on how to build a tumbling composter and I finally secured a 55 gallon barrel that I could potentially. I was told from a co-worker that the contents of the barrel were only alcohol fuel. Will I be able to use this barrel as my compost barrel and be safe from using the compost in my garden, lawn, flower, etc? I did a bit of research and it seems to be safe as some people have used composting to create alcohol fuel with a distillery. Just want to be absolutely sure and safe before I do anything.Thank you!

I have a 8 year old bro who has a bunch of nerf guns. He wanted play airsoft with me but doesn't want to get shot with my 400+ fps airsoft gun. I've been searching some things on instructables and found a way to change a nerf gun into a weak airsoft gun. My brother let me use his nightfinder and i ripped out the air restrictor. so now im supposed to make a barrel. He doesn't really like the idea of cutting up one of his darts so what is another item that i could use to make a barrel. he doesn't mind a decent fps on the gun just nothing too extreme. any other suggestions for other mods are accepted as well.
Question by youraveragepizzaguy | last reply
Hi guys! This is my new pistol concept! Its mechanism is actually pretty simple, and I have tried it once, and it actually works! Let me explain how it works: As the bullets (in this case white rods) are pushed up the guide (see picture below, it is named "bottom of loading") they are shoved up against the trigger. When you pull back the FP (Firing Pin), and it locks into position, this pushes the trigger up, pulling the first bullet go up into the chamber. When you pull the trigger, the bullet is shot out the barrel, and the next round is ready to go into the chamber. Repeat until your out of rounds. What do you guys think? ~The Red Book of Westmarch~ P.S. The image was made on paint.

I want to use the barrel for composting and hope it can be removed, I have looked everywhere and talked to many people just trying to find a barrel to begin with. There are no sources near me for the barrels so I am hoping someone can help me figure out how to remove the residue left in this barrel.
Question by Choctaw 1954 | last reply
I have a TSD SDM100 airsoft sniper rifle, and i wanted to get a tightbore airsoft barrel in in. i could not find the barrel length on the gun box, in the booklet, or online. I measured the barrel in my gun with a tape, and it turns out to be a little under 16 inches, or 455mm. On airsplat.com, i found a barrel that matches the length, and is a tightbore of good make. However, it is labled that it is for AK47 type guns. it looks no different than the barrel in my gun. Is it okay to get this barrel? Will it work? It is expensive, so i dont want to get it and then have it not work. Any and all help appreciated. Could i possibly get a longer barrel to be safe and then cut it to fit?

Hello. I made a Paintball-to-Airsoft-sniper conversion about a year ago. (Instructable soon! Don't worry. And another one after that!) I saw these Barrage barrels and wanted to know if anyone uses them or has used them, and what they think. My conversion uses a longer home-made barrel, not a Barrage barrel. These barrels are used in normal paintball guns to shoot BBs in .117 (bb gun bbs) or Airsoft (6mm) calibers. The barrel comes as a one-piece part that you just screw on. It has a Feet-Per-Second adjustment that supposedly ranges from 175FPS to 450FPS. There is an attached hopper that you put the ammo in. the barrels are about ten inches long, and made of solid aluminum. Anyway, anyone know anything about them?

Does anyone in here knows what real gun barrels are made of? I know it's metal (duh!) but what kind of metal/alloy? Steel? Iron?What is the thickness of the pipe? (not the diameter, the thickness of the walls.) How do the manufacturers of these guns be sure that the barrel does not explode? How can the calculate the pressure inside the barrel?
