Step 2: Grenade launcher shell

Disassemble the dollarama party popper and keep only the tube. You need to remove the bumps and line inside the tube. Mesure 8 lenght of toillet or sink pipe, cut them then glue them with the hot glue gun. Glue an electrical cap in the center at each end. Make a little lip so that the bbs don't fall in the launcher on one side of the shell.
<p>Whats the FPS or minimum range and what bb's did you use </p>
<p>Your idea with gluing the thumbtack and the &quot;screw tight&quot; and &quot;don't screw tight&quot; is leak prone. </p><p>&quot;There are engineers, and there are the rest of us.&quot;</p>

<p>Better Idea: Use a good teflon tape like the yellow or pink type. 2 to 3 wraps is good. Next, add Rectorseal Tru-Blu. For a better idea, use a CO2 quick change.</p><p>Parts:</p><p>Co2 quick change:</p><p><a href="http://www.amazon.com/Rap4-Paintball-Quick-Change-Adapter/dp/B0046VLEOK" rel="nofollow">http://www.amazon.com/Rap4-Paintball-Quick-Change-...</a></p><p>Strong Epoxy like JB-Weld</p><p>Yellow Teflon tape</p><p>Rectorseal Tru-Blu sealant:</p><p><a href="http://www.zoro.com/i/G1543936/?category=6232" rel="nofollow">http://www.zoro.com/i/G1543936/?category=6232</a></p><p>1/2 inch steel coupler</p><p>1/2 inch by 6 inch steel pipe nipple</p><p>1/2 inch valve:</p><p><a href="http://www.zoro.com/i/G4976745/?category=5796" rel="nofollow">http://www.zoro.com/i/G4976745/?category=579</a></p><p>DO NOT USE BRASS VALVES!

<p>This is not spam, but a warning. PVC will fail suddenly after a while. This was band member that hurt badly by a T-Shirt launcher explosion.</p><p><a href="https://fundrazr.com/campaigns/1Zs3c" rel="nofollow">https://fundrazr.com/campaigns/1Zs3c</a><br>..</p>
<p>THIS PROJECT IS NOT PVC! DWV plastic pipe is the shell, the real pressurized parts are metal.</p>
where do you get a dollarama party popper?
more like a master key (shotgun under barrel attachment)
costs about $17.76 from tractor supply
what is the average cost
ol all my teamates were look at me like what the heck are you doing
How much does the shell weigh?&nbsp;Im trying to build something similar but idk how much a 16g Co2 cartridge can shoot.<br />
about the co2 cartridge: where to get it? is it used for paintball guns? or maybe for a soda machine?
those ones, sometimes are used for paintball guns, but they are more commonly used for bb guns and air rifles. they are also relatively common for CO2 powered airsoft guns. you should be able to find them either online, or the sporting goods section of your local department store, by the airsoft and paintball guns.
my local deparrtment store doesnt have airsoft, i have to go to a weapon store (they sell real weapons, paintball and airsoft). i now use a 300grams CO2 soda-machine-cartridge. ill post an instructable soon
why do soda machines need a co2 cartridge?<br />
....sigh....WALMART and if you're canadian....CANDATIAN TIRE
What about attaching it to the gun? you would need a rail grip. Where can I find a how to on the rail grip?
buy a rail, glue it on, done
or a screw tube (metal band which is tightened around the fixture using a screw<br />
&nbsp;how do those ball valves hold up to the pressure of the co2? where did you get them?
how many shots well you get out of one co2 can
How much would this cost?
could I use these valves?<br/><a rel="nofollow" href="http://www.minitruckin.net/product_info.php?cPath=34_35&amp;products_id=133">http://www.minitruckin.net/product_info.php?cPath=34_35&amp;products_id=133</a><br/>
those would be ausome
kinda big. youre forgeting the whole purpose of the gun. AS SMAL AS POSSILBE
i don't see why not
Is the shell thing like an airsoft shower
what pressure is a normal co2 cartrige at
looks cool im gonna try it =]&lt;br/&gt;a vid would be great &lt;br/&gt;<br/>
I take the risk of sounding stupid, but could you explain how the grenades themselves work a little more?
the co2 cartridge is used to shoot all the airsofts out of the party popper. It's essentialy a small pneumatic potato cannon.
what about attachment? is there a rail attachment to these steps?
wow with just a 12. gram
How many shots can you get from one CO2 cartridge?
about 5 to 7
Wow thats more thani thought it would. Great job!!!
thanks i'v been looking 4 something like this
how many times do u have to pump to pressurize it?
u dont have to pump it. IT USES CO2. just open the back valve and colse it. this will pressurize the chamber. ;-)
nice, i hate those overpriced commercial ones.
HAGh u said NIPPLE!
