kingspaz Frequent Poster	posted April 23, 2000 05:34 PM i have made a rocket launcher and it has a hatch at the back so it can be quickly re-loaded it works like a dream and eeverything on it that i have thought of works but my brain just can't semm to get into gear when it come to a sight. any ideas?? heres a diagram of what its like did the pic turn out??!!!
m3nth Frequent Poster	posted April 23, 2000 07:47 PM look at the post yourself... there is no picture. speaking of which... shouldn't this post be in the iw section?? is everyone turning into brainless morons these days? i just saw that pic of some 12yr old playing in his backyard... does no one have any common sense? get a laser pointer pen for $30 or however much they are and mount it on top, rewire the switch so it is operated by your thumb next to your trigger finger. that is if you are using a trigger for ignition. otherwise just mount it on top, throw the rocket it in and light it then hold the button down on the laser pointer to see where it's gonna go. won't work in the day time maybe but you could always just put a little 1" piece of 3/4 pipe to see where it's gonna go on top of the barrel. ~m3nth~
BrassMonkey Frequent Poster	posted April 23, 2000 08:54 PM One way to make a site is to take a piece of plastic or metal about five times as long as it is wide (about 1"x5" depending on size of weapon) and punch holes about one centimeter apart starting at the bottom going up. Then go to a field or something and shoot the thing straight out. aim at a point that you know you cant hit while looking through the top hole, and when the rocket hits the ground measure the distance between the point you were standing at and the point where the rocket hit. Record this number. Then do the exact same thing (standing in the same place aiming at the same thing) but look through the second hole from the top. when the rocket hits the ground measure the distance between the first rockets point of impact and the second rockets point of impact. Also record this #. Now first thing is, if you want to be able to aim closer to you than the point where the first rocket hit than you need to either increase the length of the site, or move it back on the launcher, or both. Anyway write, with really small letters, the distance that the first rocket hit the ground under the top hole. Then add the second # (which was the distance between the two rockets) to the first and write that under the second hole. repeat for each hole. BTW: in case you care, this is the site used on most military rocket launchers.

kingspaz Frequent Poster	posted April 24, 2000 04:11 PM sorry Ho ju it was a dumb ass question but well i'm new here and i wanted to see if anyone would reply.....no more shit questions!!!
Ho ju Moderator	posted April 24, 2000 04:41 PM you could make the laser pointer better by jacking up the power so you could see it at a farther distance. Rockets tend to fly pretty level and then then just drop (that has been my experiance) so a laser pointer with a higher power should work well. ------------------ -Knowledge is power, power leads to corruption, corruption is a crime, crime doesn't pay.

kingspaz Frequent Poster	posted April 24, 2000 04:54 PM Ho ju thanks i will give that a go!!!! i'll tell you if it works
Vpr Frequent Poster	posted April 24, 2000 07:36 PM Re: Mil. rocket launcher sites. At what range do you think one should take into account relative humidity (relates to air density) in calculating trajectory... I know, dumb question, just curious, are these fixed sites or adjustable, and do they compensate for atmospheric conditions? I like the suggestion you gave for the model rocket. Having enough data you could hit a target in the dark. Anyone know the first year that a cruise missile guidance system was tested? I'll probably be out of here for a week, limited access to an online computer, other reasons.
Ho ju Moderator	posted April 24, 2000 08:10 PM Kingspaz, the only problem with jacking up the power on a little laser pointer is that the diode will burn out in a very short amount of time. get the cheapest laser you can find because you will end up destroying it after a bit of time. ------------------ -Knowledge is power, power leads to corruption, corruption is a crime, crime doesn't pay.

VeHeMT Frequent Poster	posted April 25, 2000 01:18 AM Don't input more power into a laser pointer. If it has a cheap voltage regulator than it will burn out. If it has a good one(even the good ones can only take so much...), than it will give you no difference. Cryogenically cooling the laser diode is another thing though....
VeHeMT Frequent Poster	posted April 25, 2000 01:22 AM I just got another idea after I posted. Get the cheapest airsoft spring pistol available, attach it to the rocket launcher(hey it makes a nice handle too!) and shoot 6mm paintballs (specially made for airsoft) out of it! Problems would be short range and still limited visibility, but you get a nice physical mark denoting the target. At night you could use glow in the dark bbs(also available in airsoft), just install a mag lite, light bulb in the magazine near the top with a passage made next to the top bb so that when its on, the light is emitted onto the bb.
kingspaz Frequent Poster	posted April 25, 2000 04:26 PM hi everyone Ho jo i got my laser pen and decided to separate the ruby tube and mirrors and use it to make a more powerful laser but anway i couldn't find a way of getting it out the metal case. anyway i put the power up from 4.5 v (if my maths is correct) to 7.2 v using an rc car battery. the laser was quite a bit brighter but still wasn't visible very far even today(it was very cloudy) next i will try to construct a sight as someone else suggested
Predator Frequent Poster	posted April 25, 2000 06:42 PM Laser keyring pointers don't utilise a ruby rob and mirrors They use a very small laser diode, which is about half the size of a normal led. The casing contains: Battery compartment, circuit board to supply 3 inputs to the laser diode, and the (usually) brass round thing that the laser emits from just houses a small lens to focus the laser light coming from the diode. I took mine apart by cutting with a small hacksaw lengthwise, but be warned... once you take it apart you can't put it back together again. And carefull when moving the small circuit board about, it is only connected to the laser diode via 3 very thin legs, they bend very easily.

BrassMonkey Frequent Poster	posted April 25, 2000 10:25 PM Vpr: I dont know about the humidity affecting the trajectory of a rocket, but there are many other factors that would change the impact point, such as wind, badly made nozzles etc.
kingspaz Frequent Poster	posted April 27, 2000 03:38 PM Predator, thanks for that, now i'm glad i couldn't get it apart!!
RDX* A New Voice	posted May 17, 2000 05:36 PM To answer Vpr�s question about the first cruise missile. I can say that the first were the German�s V1. The guidance system ware genuine mechanical and relyed on a compass. And when it arrived in London did it explode around 100m radius from it�s target. The onley problem with the V1 was that it was to slow so the Anti-aircraftguns were able to shot it down.This is why the V2 were made it were impossible to shoot down. V1: http://www.zenza.se\vw\gh610a_b.jpg a site with V1 blueprints and some nice pictures: http://www.zenza.se/vw/v_main.html ------------------ RDX* Sweden "Abusus non tollit usum" [This message has been edited by RDX* (edited May 23, 2000).]
ClintonxSucks Frequent Poster	posted May 17, 2000 08:13 PM theres few mistakes in your info with the V1. Frist, it did not hit within 100m of its target, only "80% of the missiles would land within 8 miles of its target", which during WW2 wasnt that bad. Also do to the V1's 4000ft-5000ft alt. it was difficult to shoot down( with AA guns) becuase it was too high for low alt. AA guns and too low for high alt. AA guns, the brits even tired to make 57mm gun to control this air space gap, but it didnt work out.
