John, I saw (briefly) a message relating to my search for a model of a Remington 700 rifle. I believe the message was from you, but I'm not sure (could have been JNJ – or I could just be confused). Anyway, I wanted to let you know that I appreciated your help. I've sent a letter off to Remington to see if they will give me copies of drawings. BTW, since this is an unclassified government weapon system, do you know if specific info (such as the drawings), is required to be available for the publics' use? We are the paying the bills after all! Thanks again, Bob W. ps If you didn't send the other message, please disregard everything you just read. 🙂

Bob, It was I who responded earlier. (I warned the JNJ guy of the potential confusion if he also used a similar three char signature; oh well…) I've built several rifle models ranging in complexity from a simple external mesh to a highly detailed AK-47 with precision internal parts. I borrowed an AK-47 and disassembled it to measure all the parts. I think this is is some ways quicker than working from drawings, but perhaps not as precise. I lofted crossections down a path with some tilt applied to create the stock. I did the rest of the gun in AutoCAD using AME. This was easier for complex objects like the bolt because of the drafting features of AutoCAD and since you can easily do a dozen or more booleans on the same object and still get a clean mesh. AME also was great for chamfering edges which is more difficult to to with 3DS. This was, however, before the booleans were improved in R3, so I might try the whole thing in 3DS now. I think it is much harder to work in 3D in AutoCAD. Perhaps I'll upload some rifle pictures in the new showcase forum if you are interested. Do you do military stuff in general? I've also built some highly detailed vehicles including a M109 self-propelled gun. (looks like a tank to me <g>) I occasionally build custom models for people if you need one and don't want to do it yourself. I thought from an earlier message that you needed a M24, whatever that is. Is that the same as the Remington 700? (I'm basically a firearms moron.) The best resource I know is forensics expert and animator Alec Jason [71137,2632] who frequents this forum. He created a video series on firearms and their effects, publishes a ballistics journal, and has many contacts in the field. I don't know about efficient access to government information. My wife works for the government in the information business and would probably know, but she is in Washington at the moment. I could ask her the next time I see her (which <sigh> won't be for a while since before she gets back, I leave for the same destination – we'll pass each other in the air.) JKJ

John, Well, I'm glad I got the right guy! Thanks again for the info. I'll see about sending a message to Alec. I'm also waiting on a reply from Remington, although the guy I talked to on the phone seemed like a d**k. BTW, the M24 is the military designation for their current sniper weapon system-which I use once a month in my guard duty. >> I could ask her the next time I see her (which <sigh> won't be for a >> while Just keep in mind the old saying along the lines of "absence makes the heart grow fonder" There is also a variation to keep in mind though-"absence makes the heart grow fonder; but too much absence makes the heart grow fonder for someone else" (g) Bob W.

Bob, The Model 700 Remington rifle is not government property. It is manufactured by a non-government corporation. The US Army purchases those rifles from the Remington corporation just as they purchase software, medicine, boots, etc. The designs of everything the US Army purchases are not automatically "available for the public's use." Even if you can get the drawings for the 700, building meshes from a drawing is very difficult and unless you are extremely skilled at reading blueprints, I would strongly suggest that you simply to go out and buy or borrow a 700. They are very common rifles. You could probably buy a cheap used one from a pawn shop. There are, however, some differances between the commercial model and the military model (such as the a heavy barrel, scope mount, and scope on the M24) which may not be important as the internal functioning of the weapon is the same.

Alec, Thanks for the reply – before I even had a chance to address a message to you! a few comments: >> Even if you can get the drawings for the 700, building meshes from a >> drawing is very difficult and unless you are extremely skilled at reading >> blueprints I would have to disagree with you here. If I've got accurate drawings to work from, I find it very simple to build meshes. Using an actual rifle (which it sounds like I'll end up doing 🙁 just adds an additional step for me – instead of reading a dimension off a drawing, I've got to measure, write and then read. Since I am building this to be the M24, the barrel, scope mount and scope are rather important elements – as well as the adjustable stock. Bob W.

PMJI, but all this discussion of getting a M700 (M24) and then disassembling it to measure parts in order to build a 3D mesh is frightening. The disassembly and subsequent reassembly of firearms is best left to a competent, professional gunsmith. If done improperly, this act could render (no pun intended) the weapon useless at best or worse yet lethal to the next person that pulls a trigger on a live round of ammunition. Please, please proceed with extreme caution; tinkering with firearms is a bad idea and should be left to those trained to do so. My guess is that there is a local gunsmith that would be more than happy to assist you in this endeavor. Of course if you already *are* a trained gunsmith then I apologise for wasting any of your time. Cheers, Frank (firearms collector, 3DS user, and generally nosey bast**d)

Hi Frank, Just thought I'd reply to your message to set your mind at ease! The only dissasembly that I would be doing is "authorized maintenance" according to the TM for the weapon. I probably won't even have to separate the barrel from the stock (ie. the only dissasembly will be to remove the bolt). Since either myself or my partner will be the only ones firing the weapon, I would seem to have a rather personal stake in being safe. Bob W.
