Thanks Enkidu for the books. Looks like it would be easier to just go buy one of the empty LAW launchers from my local army navy store, and then create the rockets for it. Also that other book about how to make your own Bazooka looks like it would work.

TheFallen I didn't know it took that much velocity to fire a sabot round, thanks for letting me know(that would have been bad). As far as the stabilization goes I was planning on going with both. I have been reading about the different types of stabilization systems over the last 4 days, and have read the same thing over and over that you cannot beat having both systems.

As far as the Warhead is concerned that is not a big thing. the only thing I have to figure out is how to create a moldable HE, that will pack enough of a punch to penetrate 1/2" of steel plate with a copper plate(the same HEAT technology the military uses). If I can acomplish that I will be happy. I am not sure whether I want to go with a homemade version of an HE, or just pony up the money and get some true C-4 off the miltia groups in NC. I already have figured out serveral different triggering methods to detonate the warhead but depending on what HE i use ddetermines what triggering device i use.

@cowboy: Maybe you have the money for LAW tubes and C4. I don't. However, I've got a list of projects that you could help me finance if you've got that kind of money. I'd even give credit to you as the sponsor.

If you're into buying things, here are some working training rounds for sale.

@TheFallen: Again, what requires such a high velocity? The sabot carrier, or a sabot round? I can't see a carrier taking that much velocity just to fall off. However, you are right in that you don't see any shoulder fired anti-armor weapons with sabot rounds. I haven't really considered sabot rounds before for that exact reason, but now that it's been brought up, I'm not quick to dismiss the idea. I think (if the velocity thing turns out not to be an issue) that a carrier might be a way to reduce friction and keep the rocket snug in the tube.

You're also right that the design of the rocket is a huge concern. I meant to include that in the 'apparatus for launching the projectile' sentence. It's where we gave up last time.

The actual armature, the sabot would fall off, but the armature works by having such a high velocity and high weight, with a small cross-sectional area. Not something easily achievable with a poor mans RPG. Also a SABOT round is specifically for main battle tanks, it's go straight through an SUV with ease and not do that much damage.

I agree. See i have been thinking through this all night and now that I have had access to the proper references(thank you Enkidu), I have found a great way to do it.

Its not that I have that much money, it's the fact of my dad is now a cop but he is ex military, and he has friends. I am gunna try and grease that wheel, and see if one of his army/air force buddies can get me one that has already been fired. They do reload them but not all of them. He won't even ask questions. As for the C-4 You can get that in the NC or Tenn. mountains for like $250 a 5lb block. DO YOU KNOW HOW FAR 5lb's GOES? That is a whole bunch of fun..........

The only thing is blasting caps or det cord to set it off with...........

Now I am thinking Sabot rounds because that way the surface area is greater, and I can set this up like an RPG-7. They have a small charge that sets them off, pushing them out of the barrel, then the main charge burns and it takes off.

Now back to the launcher itself, I am going to reference 2 books that Enkidu listed on Rapidshare. I can build the model listed in "How to build your own Bazooka" but modify the diameter of the pipe to match the small tube on the LAW. Then to make the projectiles I could just follow the instructions in "LAW and Disorder.

Well let me know whatcha think. I am going to d/l that CGI program TheFallen listed and try and come up with a 3-d version. Give me your opinion of any changes you think I should make and I will make them as I go.

wow this got really long.........

No. Sabot rounds are inert, they are essentially a very heavy dart. no explosives, nothing, they go THROUGH the target, they use their MASSIVE kinetic energy to damage the tank.

Buying C4, hhahhaah have fun in jail...

As for buying fired LAWs, the launchers possibly, but the actual rockets, VERY unlikely.

Ok TheFallen, that is completely wrong. I am not calling you out, or trying to start a fight but I know what I am talking about. I am quoting from Wikipedia, and i will bring in some military links as well on this one.

A sabot (pronounced "sah-boh") refers to a device named for a shoe used in a firearm or cannon to fire a projectile or bullet that is smaller than the bore diameter. Since a strong seal is needed to trap propellant gasses behind the projectile, and keep the projectile centered in the barrel, something is needed to fill the gap between projectile and barrel, which is the role of the sabot. Firing a small size projectile wrapped in a sabot raises the muzzle velocity of the projectile.
Link to full story: http://en.wikipedia.org/wiki/Sabot

Oh man I see where you got that from. I retract my previous statement. I am seeing serval websites about the 120mm AP Sabot round. I am talking about something completely different.

This is the sort of technology I am talking about

Link: http://www.strategypage.com/military_photos/200475.aspx

I hope any confusion will go away with this information. Also below I have inserted a picture of the .54 cal Sabot round I use in my muzzleloader when I go deer hunting. Sorry if the pictures aren't so great, but you will get the idea.
