#341086 Full Auto Barricade

Posted by Isbjorn on 08 August 2014 - 04:06 PM

This is my first nerf gun mod (and my first post) so forgive any mistakes I make (quite a few) but I documented it fully in case anyone is insane enough to try it.

This is mainly a post to outline what NOT to do so people don't make the same mistakes I did

once again I have no idea why anyone would want to do this as the nerf Rapid Fire cs-18 is out and is way more powerful and reliable

So here we go

Step 1: find your old barricade. Here is mine. It is stock.

Step 2: Take out the screws
Posted Image

More steps:

Remove the turret
Posted Image

Cut out a well for the magazine (yellow piece in upper left hand corner was cut out)
Posted Image

Cut off the rotator thingy for the turret (turret advancer or something)
Posted Image

Take out the manual dart pusher mechanism (some screws must be removed to do this)
Posted Image

Put a push button switch in behind the trigger, also take out the jam door at this point
Posted Image

(okay this wasn't my FIRST mod, I removed the locks from my stampede, but that's it. And I guess I "minimized" both my nitefinder and stampede)
Posted Image

Draw a square where you gonna put your motor
Posted Image

Cut out said square (I used a drill and file and wire cutters)
Posted Image

The next few things ended up not being in the final product so I'll keep them brief

Posted Image

The gear tooth mechanism ended up not working (It can be done but you have to reduce the speed i.e modify the gear ratio
which is difficult with very limited space inside the blaster, and I was tired of dealing with it)
Posted Image

Gear tooth mechanism used original puller back spring
Posted Image

Got everything wired up to a 9v (it's actually a 12v motor)
Posted Image

In short, this wasn't very reliable.
Posted Image

Sooooo I took it all apart and moved the motor back to better suit my purpose
(this requires some measuring and stuff to figure out how far the pusher needs to go etc.)
Posted Image

Replaced the mechanism with a more reliable one using some more lego parts (had to cut apart a few studs etc.), a bit of tin, some scrap metal from a binder I took apart, and hot glue.
At this point I also cut out an indentation in the top so the parts could make a full rotation
Posted Image

Added a guide for the dart pusher (when put together it will keep it from popping up)
Posted Image

Put it back together, covered the big hole with packaging plastic and hot glue, and filed the stock attachment point inside until I could fit a 9v in there snugly.
Posted Image

Used some fat electrical tape to make a guide for the magazine.
Posted Image

Finally hot glued the wires in place so no connections would break. The battery can still be removed and replaced. Also make sure to cut a little hole where the wires go into the push button switch, and to make room in your cut for the motor for the wires running in over the top.
Posted Image

Probably do this outside instead of on your desk in your room.
Posted Image

As previously stated, not the most reliable blaster in the world (I need to up the voltage to 12v for it to not have the awkward "Ugh I can't push the first dart" issue, and I have neither a 12v batter nor trustfires)

Thank you guys for bothering to read my post, I had a good time modding the blaster, and learned a decent amount, hope I shared some of it with you!
