What you will need includes:
1.5” sink drain
1” cpvc endcap x1
3/4” cpvc endcap x2
Spring (You will have to experiment here, I made my own)
The first thing you are going to want to do is cut your plunger tube to this length to 3 1/2" long
Now, you may notice that the shell is currently unwilling to accept the new plunger tube.
Beat it into submission:
Now we need a way to hold the plunger tube in place. To do this, scratch up the top of the plunger tube and fix some epoxy putty to the scratches:
Make sure that the plunger tube still fits inside of the recon.
Once the putty has cured on the plunger tube, apply some to the inside of the shell, lubricate the entire plunger tube, and then press the plunger tube into the putty in the shell
Upon carefully removing the plunger tube, you should be left with this:
Now we shall assemble the plunger rod. Take your 3/4” cpvc endcap and cut a 1/4” groove in it, 3/16” from the sealed end. Now sand down the edge on the hollow end.
Hopefully these pictures clarify my crude explanation:
Drill a hole through the center of your plunger rod and endcap.
Now, to assemble our plunger rod, we will put together our materials in this configuration:
(I just used the smaller washer because the larger one would not hold on to the screw)
Fasten them together with your screw:
This is definitely not the best way to make a plunger rod, but it will have to do. Feel free to use your own seal making methods.
Another spring rest is required in order to make this blaster function, so cut the second 3/4” endcap to about 1/2” tall and drill a hole through large enough to accommodate the plunger rod:
(Mine is a bit less than 1/2”)
Now hot glue it where the stock spring used to rest:
Because we are now using a normal plunger system, we need to redo our catch to accommodate said system.
Take your 3/16 polycarb (or glue together two pieces of 3/32” polycarb” and trace the outline of the stock catch onto it.
Now cut out the catch to make it look like the picture:
Sorry that I don’t have a template or exact measurements. Just make sure that the catch is at the bottom of the groove of the shell when it is firmly in the groove on the plunger rod. Also, don’t forget to upgrade your catch spring.
Some quick reinforcements before we make it shoot.
Get a bread clip:
Cut it up like so:
Now glue it beneath your trigger arm:
This makes sure that pulling the trigger actually fires the blaster.
Finally, we have to make the breech. I will be constructing a 17/32 angel breech, but a 9/16 would work fine.
First, cut 5 1/16” of 9/16 brass, and add a 1 1/2” lip like so:
Now cut 1/2” of 17/32 and 1/2” brass respectively:
Pull out your 15/32 brass and cut off a 3 1/2” piece:
Glue all of these into the 9/16 using your favorite superglue, making sure the 15/32 is slightly behind the lip of the 9/16.
Now add a circle of neoprene to the end of the bolt:
To seal the breech with the plunger tube, cut a 1” cpvc endcap right at the end, like this:
Drill and sand a hole in the center to accommodate the bolt:
now goop, epoxy and hotglue a #11 o-ring over the hole:
You can then goop the endcap into your plunger tube, making sure it is level with the end.
Slip the bolt through the hole in the endcap and then add the breech connection nub, measuring 1 7/8”:
(Be sure to sand both surfaces)
Finally, we will add the barrel. Cut a 3 1/16 halfpipe in 17/32 brass and position it like so:
Wrap enough e-tape around it to support it in the stock faux barrel:
Reassemble, placing the internals like this:
Congratulations! You just finished your Nined (can I call it that?) Recon!
Ranges fall between 50 and 70 feet.
Edit: fixed seal and added firing video.
