Crossbow bolts

Crossbow bolts are considerably expensive. I just invested in a crossbow and I'm looking for a cheap way to make practice bolts. Given many tutorials out there that explains how to melt aluminum and how to cast things from aluminum, I was wondering if someone instruct us on how to properly create a crossbow bolt (and arrow)

A Few Random Crossbows

I was bored so I made a few small crossbows, the ones with rails are more like indoor toys...they shoot everything and tend to keep it in one piece (most of the time) xD That little crossbow without rails still packs a punch, so don't try and shoot it at someone o.o' And uh that also counts for the other 'little' crossbow.

Van Helsing Crossbow

I just finished watching van helsing for the umpteenth time and the crossbow that carl gives him is one of the only cool things in the movie, apparantly its steam driven works like a machine gun and uses magazines of crossbow bolts. So my question is, is it possible to make something of the sort using technology from that time? Unfortuately I havent had any ideas on its useage or working as yet.

Huge working crossbow!

In art class in school the other day, I took a bunch of random things - this metal thing, some yard sticks, a ruler, fishing line, a plastic thing, and this wooden bit, and made a giant working cross bow. The trigger system consists of two chip clips. With a bad piece of fishing line, the rnage is 40 feet.

Decimator Crossbow (v7)

Well I finally got some more pieces, more still coming; this enabled me to build something bigger =dThis crossbow(more like cannon, now) has the following specs:Ammo: 1 Standard arrow, which needs to be ductaped other wise torn to shreds.Weight: 4,5 kilo's (9,92 pounds)Range: Not tested outside, will beat the Reaper and the Blockhead for sure.Rubberbands: 32, 8 strings of 4 ( these may still be increased as it shows no bending yet.)Power: Just look at 2nd picture....should explain a lot.Trigger: Same as on the Blockhead, some big improvements on it though.(Surprised about how power much it can take...)Sturdiness: Seems close to unbreakable lol...Without realizing..I also made a very good scope on it o.oI had a purple+blue 3d connector as arrow tip and when I fired on my cardboard box, it made a huge tear...and my ears were ringing like from an explosion O.o'Well this monster has bad points:Need a long/strong left arm if you are right-handed, because this thing is heavy as hell.Cannot fire without trigger.Every arrow needs ductape otherwise connector gets torn off.Also I gonna try and say...:I think this may very well be the most powerful ranged k'nex weapon on this site at the moment.

Freekiller Crossbow Review

Well, i wanted to do a review, so i did this! Let's go right into the review!!! Piece use- This thing uses so many pieces! And it's really small too! But the high piece count does make it a lot stronger. I give it a 6/10 in this category Strength- This gun is really strong! You can drop it, and it most likely won't break; But there are a few weak points. I give it a 9/10 in this category ROF- this thing has a good rate of fire if you have small bands, but if you are going for power with big bands, you have to load just one bullet in at a time. I give it a 7/10 in this category Power- well, it's a slingshot, that shoots gray connectors, so it's gotta be powerful! I give it a 9/10 in this category Accuracy- This thing is not the most accurate gun ever, but if you are using rapid fire, it doesn't matter about accuracy! I give it an 8/10 in this category  Mag- the mag (which i have never seen before) holds those grey connectors perfectly, but it is a weak point in the gun. I give it an 8/10 Comfort- This handle is comfy! The pull-back thing is also really comfy! I give it a 10/10! Size- This thing is small! You can fit this powerful little gun in any back pack, perfect for hiding it! I give it a 9/10 in this category Pull-backer- What else do i call it? Well, it is really comfy, and it makes pulling back bands super duper easy! I have three strings of two #64's on it and it's just simple to pull back! I give it a 10/10! Looks- This thing looks deadly! The super filled in bow, the awesome looking handles, everything! I give it a 9/10 (it's missing a little something...) Elastics- This thing holds as many elastics as any old ratchet, making it powerful! I give it a 9/10! Bow- the bow is really strong, and it looks super deadly, but for bigger elastics, the small wheel just isn't very good... I give it an 8/10 Sound- this thing sounds sweet when shooting, but if you are trying to be quiet, this isn't the gun, unless you use one of those things that i have on the ratchet of my ASCB, sooo. I give it a 7/10 Big review, eh? well this gun gets.... An 8.5!!!! Great gun from Knexfreek and Killer~Safecracker! Go subscribe to them!!! Images coming soon!

My Knex Crossbow History

I first had this up as slideshow, but the forums seem to be a better place for it.1st picture (Crossbow V1) This is a picture from the first crossbow i made and if you look at the other crossbow you can see that this one is a predecessor of it.This one however is a bit harder to fire with, since you need to lower your crossbow right after firing, or get smacked in the face by an arrow bouncing back :PIt can get about 80 to 100 feet(if fired well ofcourse) and it could be seen as a light version ofthe other crossbow. It can make a hole in a piece of cardboard (from a box)If instructions are needed, I will post an Instructable.2nd picture(Crossbow V2) already has instructions posted. Actually won a prize with it too :DIt fires 120-150 feet, also depending on wind like most arrows would do. Goes through straight through cardboard.Instructions: picture (Crossbow V3 aka Ballista ) No instructions posted, because there was not enough difference between V2 and V3 and is a bit on the heavy side :PIt has enormous power, but due to having a trigger it didn't fire further then V2.Explodes small plastic boxes, CD's, obliterates red connector of the arrow if fired straight into a wall.4th picture (Crossbow V4) never got finished because it was way too heavy and therefore it was nearly impossible to find a good handle for it. Had a good time dismanteling it....Not much to mention about this one, since it never fired.5th picture (Crossbow V5 "Reaper") is nearly complete and is fully functioning.It uses 4 rubberband strings to do the damage. It also has a new trigger system so that it can hold the full power of the 4 rubberband strings.Its topic is here: are here: picture A smaller, more piece efficient crossbow, although not as powerful as the Reaper, it is compact and easier to use.

Long Range Hybrid Crossbow

HERE IT IS. The Brickster LDS is a hybrid crossbow. It doesn't have a bow. It has a range of 250 to 300 feet with 16 to 32 rubber bands. It is extremely strong and could hold about 80lbs of force. The arrows are smaller than an average crossbow arrow so they fly slightly faster. It has no track so it is a slingshot type crossbow. Will be posted in a month or 2. Amazingly powerful. Has over 800 pieces and a Ballista attachment that rolls and keeps it at a 30 degree agle with the ground. Low piece and a great gun, If only I could show you. . . . . . . . . . . WAIT, I CAN!!!!!!!!!!

Crossbow V2 Ultimate Version

After weeks of waiting, I finally got my k'nex back after moving. One of the first things I did was solving a few problems with my crossbow trigger. It took me about 4 hours of thinking and building prototypes. The following things have changed: The friction has been reduced by a great amount. It became much more compact. Does not require ductape anymore. Does not need the exotic hinge piece. Is now very easy to fire. I decided to show the new trigger using a well-built V2 crossbow; which now can finally use it, due to lower friction. This trigger is ideal for people that want a trigger on the v2, it should be buildable from the pictures. (The coloured trigger is the first version, the same as the gray one though) Edit: Instructable:

New Low-piece Crossbow

I was building crossbows all over the place this weekend, at one moment I had one that was twice as large as the Reaper, but I lacked pieces to make it sturdy. This started out as a low amount of pieces Reaper, but I eventually made it a small crossbow which has about 80-95% of the Reapers power. Although it has the power and probably also the distance, it doesn't have a double arrow trigger(only one arrow) and I don't think it is able to fire properly without trigger. It is however, compared to the Reaper very practical, light and easy to fire/load. Btw there are 4x3 rubberbands on it in pictures. I don't know if I am going to post this one though, maybe if its really needed :P

Pump action crossbow with a mag

Alright, I've had this idea for like forever and I finally got a working prototype yesterday. It has a pump with two prongs on the side which catch the rubber band bow as it is fired and then pulls it back. The trigger is a triangle shape so the rubber band can slide over the top, but still be caught on the back. The system has a few kinks, but mostly it just isn't that smooth. I hope to work them out and eventually be posting.

New Knex Crossbow Idea

This new idea came from wickys crossbow, and I havnt got it working yet. The new idea is basically an autoload crossbow. You just rip the old handle off, and start on a new one, but on the new one you have red gears on the front and somewhere on the back of your new handle. The red gears need to be able to run black chain links across the handle. So you put black chainlinkson across the handle of your crossbow. On the chain links you could put a little hook, so that when the little hook meets up with the horizontal rubberband it hooks on to it and brings it back to the end of your handle. Not that it would be in any use whatsoever its just an auto load idea.If you didnt get this topic,tell me so I can make it a little more clearer. I have no camera that I can use right now ,so I cant show you what I have so far.
