#66027 Gun Idea
Posted by BloodMoon on 17 October 2005 - 06:55 PM in Modifications
In general, I don't think it's a good idea to start a new topic when you don't really care about the results (you're not even going to TRY to build one).
#66089 Air Tank Mod
Posted by BloodMoon on 18 October 2005 - 09:31 PM in Modifications
When I range tested, I got between 100' and 123' consistantly, with no mod to the tank itself (only the trigger). I thought that was a little high. In reality, I found out that my while the coupler is centered side-to-side, it angles the barrel upward. With a level shot, the range will be less.
Unlike you, I can't say that I've found this gun to be very accurate. With my 12" barrel, which works better than the 8" one I had before, I only shoot at people 60' away, closer if they're moving fast.
Here's some pics of my LBB:
#66091 Barrels
Posted by BloodMoon on 18 October 2005 - 09:37 PM in Modifications
I did some experimentation to determine what would be the optimal barrel length for a given plunger size. The goal was to find the barrel length for which the dart would exit the barrel as the plunger reaches the end of the plunger tube. I started off by matching the volume of the plunger to the volume of the barrel. I knew that this was going to produce too long a barrel but it was a good place to start. This would assume that the air inside the plunger and barrel is incompressible and that there are no leaks. In the real world this is not the case. I reduced the barrel length until I had found the length at which the dart was leaving the barrel as the plunger was reaching its stop, coinciding with the maximum attainable range. Experimentally the plunger volume seems to be about 4 times that of the barrel. The relation for barrel to plunger size can be summed up in the following equation,
where rb is the barrel radius, rp is the plunger radius, lb is the barrel length, and lp is the plunger length. For Nerf applications the barrel is almost always 1/2" PVC or CPVC. rb can then be set as a constant at 0.25" and removed from the equation. Since we are trying to solve for the barrel length with a given plunger size, the equation can be rearranged and simplified to:
This simple equation makes it easy to roughly but quickly size a barrel to a given plunger. The equation could also be used to size a plunger for a given length barrel. This equation is based on experimental data and is not perfect. Four is not the golden number. This produces the optimal barrel length for the situation I was testing. The type of dart, dart-barrel friction, and total system volume will likely effect the optimal ratio. Nevertheless, the above equation can be used as a starting point.
That's the most technical approach to it that I can remember seeing. When determining barrel sizes for myself, I just figure the more powerful the gun, the longer the barrel. I start at 12" and just work down from there until I get a size that works. Most 'rifle' guns that I have use 1/2" PVC couplers, so I already have some barrels lying around that I can try.
#66095 Nf Coupler Mod
Posted by BloodMoon on 18 October 2005 - 09:45 PM in Modifications
That's a very solid mod. It would be nice to have a pic of the finished product though...for some reason, that just makes it complete in my mind. I have a CPVC barreled NF that gets no where near those ranges, but I think that it's because my Stefans are a bad fit for CPVC...I've since then stopped using it.
#66182 Paper Darts?
Posted by BloodMoon on 20 October 2005 - 08:26 PM in General Nerf
I can't imagine that any darts made out of paper are as good as stefans. For starters, they have to have almost no wieight...which poses problems if you want to shoot over five feet. Next, how can they possibly make a good seal with the barrel? As they must be easily bent, I doubt that there's any good barrel for them.
#66184 The Hornet
Posted by BloodMoon on 20 October 2005 - 08:32 PM in General Nerf
I'd really like to get my hands on a Hornet, but I'm not about to buy a N-Strike, considering that they're $40 and I don't want/need the Titan or the Scout (nevermind anything else the N-Strike comes with). If they were sold individually, I'd gladly pay $15 for one, but I'm not motivated enough to find one to buy online.
#66186 Tool Prerequisites
Posted by BloodMoon on 20 October 2005 - 08:42 PM in Modifications
I don't know if you count this as a tool, but I use a vice all the time, for letting stuff dry and holding things that I need to drill/sand.
Something that I can't get enough of that hasn't been mentioned is Electrical Tape (also called Vinyl Tape or E-Tape). My main use for it is that wrapping pipe/tubing with it increases the outer diameter. I've also seen it used for added holding strengh and better grips for your guns. If nothing else, it makes things black (or whatever other color of E-Tape you'd like to buy).
#66353 Home Made Bolt Action
Posted by BloodMoon on 22 October 2005 - 09:52 PM in Homemades
Also, as a new person to Homemades (who is trying to get all the information he can), I'd like to see a list of the other materials you'll be using to make your bolt-action rifle.
#66354 New Silencer
Posted by BloodMoon on 22 October 2005 - 09:56 PM in Homemades
Just a question on the function of your silencer...I'm assuming that the noise reduction is really only an issue for pump guns, seeing as in a spring gun the sound of the spring colliding with the end of the plunger tube is louder than the dart firing (though I may be wrong)?

#66358 Springs
Posted by BloodMoon on 22 October 2005 - 10:18 PM in Modifications
For all of the hardware stores I've been in, there's been a wall of springs somewhere. Just ask someone who works there...unlike some items (like brass), springs are really common, and the people working at your hardware store should know where they are. As far as the three stores nearest to me, however, I've been unable to find any good springs for use in cocking guns, so I'm going to try to get ahold of some AR15 springs, as per Boltsniper's Homemades.In what section of your hardware stores do you find the springs?
#66359 Modification and Paintjob Pictures
Posted by BloodMoon on 22 October 2005 - 10:22 PM in Modifications
Uhh, then where would the crossbow's barrel be??Nice integretion but the pump should be where the barrelis of the sm1500, and the barrel should come out the top hole where the original Xbow's barrel was.
Here's a pic of my LBB, though I already posted the pic in some other thread:

#66428 Nf Barrels?
Posted by BloodMoon on 23 October 2005 - 04:00 PM in Modifications
Just to sum it up though, make sure you have a Brass, PETG, Crayola, or CPVC barrel for the 1/2" FBR that you are going to buy.

#66518 Barrel Selection
Posted by BloodMoon on 24 October 2005 - 06:03 PM in Modifications
If you can't get brass, that I can assume that you also can't get PETG. The other barrel materials to consider are Sch. 80 PVC (haven't used this, but some people claim it works) and Crayolas. Crayolas might be a good, slightly less constricted alternative to CVPC for your guns.
In general, if you have a spring gun (or any gun with a high air volume / slow air delivery), you will benefit from a constriction.

#66671 Boltsniper Gns Pistol For Sale
Posted by BloodMoon on 27 October 2005 - 09:08 PM in Homemades
Darn...my GNS will be obsolete before I even get the rest of the parts to build it.I took a break from it and brainstormed a new homemade that's gonna kick ass.
Not only does the GNS look awesome, the ranges are great, with an edge over Nerf's current-generation pistols.
Can't wait to see schmatics for the GNS parts as well as pics of the new gun. I can tell you that in my community alone, there are plenty of people hanging on every word you post, Boltsniper.

#67077 Size Of Pvc For Homemade Gun
Posted by BloodMoon on 03 November 2005 - 07:01 PM in Homemades
I measured some 1", and that chart seems about right, so I'd say it's pretty safe to assume that the chart is correct for the rest of the pipe sizes.
Unfortunately, it doesn't list ID's and OD's for thin wall PVC (for example, 230 PSI 3/4" PVC or 200 PSI 1" PVC), which you may want in your design.

#67496 1" 200 Psi Pvc
Posted by BloodMoon on 11 November 2005 - 10:43 PM in Homemades
As for the places that DO carry the pipe, Lowes is a haul for me, but they carry more types of PVC than anywhere else I've been to, thin-wall included. I get most of my thin-wall from a locally-owned store called Wentworth Lumber Yard. Just see what kind of places in your area.

#67658 Nf Mod
Posted by BloodMoon on 14 November 2005 - 10:31 PM in Modifications
It's a solid mod. It's a lot like what I wound up doing for my very first mod. What I can tell you about ranges on the NF CPVC mod is that you'll get very different results depending on your stefans.
Thanks, Uncle Hammer. I guess I'll also be buying a whole bunch of 'old' NF's if there are still any lying around on shelves somewheres.
#67665 Where To Buy Modding Materials
Posted by BloodMoon on 14 November 2005 - 10:59 PM in Modifications
As far as brass goes, I'd say that if you're new and you have an Ace nearby, that should be the first place you check. Of three Ace stores, I've found brass at all three. That doesn't mean that all Ace's carry it, but it does mean that it's worth checking. Be aware that brass is a relatively uncommon item, so you may have to search the store yourself.
I have never seen brass at Lowes. I haven't been to more than one Lowe's though.

#68808 At2k Quad Mod
Posted by BloodMoon on 04 December 2005 - 11:57 PM in Modifications
Just one question that I've never really asked. What do you do to get the darts into the back of the barrels? Do you ramrod, or is the fit loose enough that you can just blow them down?
#69053 Question About The Far
Posted by BloodMoon on 11 December 2005 - 07:33 PM in Homemades
I'm thinking that it would be actually cheaper to buy a springer than to try and get all the parts for building a homemade one.
Also, I'm not sure the FAR is the best place to look for ideas on this. The FAR was designed with bulky foam ammunition in mind, so I don't know how much of Bolt's design is going to be relevant to what you're trying to do. The FAR is a good primer for a project like this, but I think that you're going to have to redesign the magazine system to work with the BB's, which will be no small feat.
#69895 Dart Tag Mod? Yes I Searched
Posted by BloodMoon on 26 December 2005 - 07:03 PM in Modifications
Maybe I'm just better at searching (don't know how that's possible, you just type in what you're looking for), but I did find this: Flamebo's Mod
