Introduction: Double Tr18 Instructions

Picture of Double Tr18 Instructions

Hello, I made this from Dirtyboyy's pictures he posted. I managed to make it from the five pictures he posted. (Some spots are mine like the modded front sight and the handle and some inards). It's a double Tr-18. I would like to say that 5% credit goes to KillerK for the turrets and some of the trigger, 80% to Dirtyboyy for the gun, and the rest to me for making the instructable. This is my first of hopefully many instructables so don't hate. However i will accept constructive criticism as I do not know how to really make an instructable so I am hoping that this turns out just fine. O.k. so on to pro's and con's!

Pro's
-Packs a punch
-Shoots white rods 120+ feet. (Yellows 50+)
-Has two turrets of 17 shots. (34 total)
-I have instructions to make it have two triggers or to just have one. (I prefer the single trigger)
-It looks very cool.
-Comfy handle and foregrip.
-Sights for shooting both barrels at once and also individual sights for each barrel.
-Ramguide
-Very sturdy
-Good rate of fire
-Turrets don't sag!
-Fun to build

Con's
-Takes a long time to reload.
-Uses a lot of pieces. (Sorry but i did not make a parts list)
-It's kind of heavy.
-Uses like ten broken white rods, two broke red rods, and one broken y connector. (These are optional though except for the red rods)
-May be too big for some people.
-Need to hot glue and tape the ram or it will blow up from the force of a lot of rubber bands.

Stats anyone...
-Weighs exactly 4.5 pounds.
-27 1/4 inches long. (Without ammo in)
-Width of about 10 inches at turrets and 3 inches at stock.
-11 layers thick. (Yellow rod)
-Shoots white rods 120+ feet.

***DISCLAIMER*** KillerK, Dirtyboyy, and I are not responsible for any damage that may be done by this weapon.

DON'T FORGET TO RATE!!! (Please tell me if there are any problems with my instructable and I will try to fix it.)

O.k. so build it...NOW!!!

Step 1: Build the Turrets

O.k. so build two. Thanks to Hiyadudez for the turret pictures. (Some of Hiyadudez' pictures wouldn't upload correctly when I tried it.) (The last three pictures are mine) You should still be able to build it. Follow image notes.

Step 2: Front Barrel (Big Block)

Alright so I took this apart and took some decent pictures of what to make. Have fun. (You will have broken fingers by the end of this step.) Some spots are marked to put reenforced red rods. They are optional but recomended. Follow image notes.

1. What you will make
2. Make this. It's two red rods full of white connectors connected with 2 green rods. TIP: When connecting the two rows of whites together only use one green rod on each side. Don't fill the whole thing up.
3. Other view
4. 11 white rods
5. Build this
6. Other view
7. Build a mirror opposite
8. Make
9. Make
10. Pay close attention to the way the brown clips are faced
11. Make, be sure to use reenforced red rods or the turrets will sag.
12. Gather
13. Gather. If you don't want to cut the Y clip then don't gather any Y clips for this picture.
14. Make this block. Sorry but it's impossible to take that apart.

26. Bottom view of connection. This is the most painful connection of the whole gun.
27. Attach the wheel and axel.

29. Add the front part of the front sight. It fits perfectly between the pieces sticking out of the white connectors.
30. Add the back part of the front sight. If you dont wanna cut the Y clip then don't add either one.
31. Reattach the plate. Aiming down the sights.
32. Add the yellow pieces from picture eight.
33. Attach the left wing. Very painful.
34. Attach the left wheel and axel.

Dirtyboyy (author)2012-09-13

Hi knextremist, its really about 2 years ago i was for the last time on instructables. I saw your message for permission and you have. I am glad you posted this awesome gun so people can make this. I quit knex 2 years ago so i would never be able to post this gun. Good luck boy, thank you for posting and have loads of fun with it!

~Dirtyboyy

knextremist (author)Dirtyboyy2012-10-23

Great gun on your part! And thanks for the permission!

~Meme~ (author)2012-08-22

Three TR18's or three shot? Three would be wierd! Ha.

~Meme~ (author)2012-08-21

It would probably have to be mounted on some sort of a tripod if used in battle because it's pretty colossal! XD

knextremist (author)2012-07-11

Glad you like it. It is a fun build so I think you should make it.

maybe

mulletman6 (author)2012-07-08

I made this ages ago from the same pictures as you did. Was kool, but the whole back end is pointless . I removed the whole back end and had it as more of a massive pistol

knextremist (author)mulletman62012-07-11

Yeah the stock is 100% opttional, I like it though.
