Okay I will first mention that I will remake the knexsayer and the tr-18 turret, so here are the credits.
Knexsayer body + mech (mepain)
Turret (killerk, bakenbitz)
Some pictures (hiyadudez)

I really like this gun and Im pretty sure you could get alot more range with four rubber bands but when I used four, I got about 90 ft but the pump broke after about 4 pumps, (if you want to try more than 3 64s then you should probably use more tape than i did.

Okay here we are with the stats

Pros:
Comfy Grip
Range (I got a white rod to fly 80feet)
Really Good ROF
Very powerful
18 shot turret
Reinforced RamRail
Comfystock
Very STrong Design

Cons
Uses alot of pieces
needs tape
The Turret kinda sags

Step 1: The Turret

Okay this is Hiyaduyez step, he also has total credit because I was too lazy to take apart the turret, if this step.

1- 17 are all different views of the turret
and

The last 8 pictures are how to assemble

Step 2: The Front Portion Part 1

Okay I hate steps with like 50 pictures to I split it into two steps

This is where most of my mods are
I got lazy, I really didnt want to take the knexsayer block apart so I just took alot of pictures, If you have questions comment or PM me.
Here we go
you will have broken fingers

ps: look at the notes

1. okay this is what your going to make
2- 9 I hope you can figure it out

Step 3: The Front Portion Part 2

Next part
THis is where all the minor mods come in

1. what it look like
2-3 make this
4 attach
5 make
6 attach
7 make
8 attach in front
9 attach
11 make
12 attach
14 add this rubber band
16 the rubber band goes there to spin the turret
17 these grey connecters + the yellow rod are very important dont miss it
18 find these pieces
19 put them in the front
20 get this
21 just a view of what you should have
22 make this
23 attach here
24 put the grey rod here and make sure you have the spacers
25 awsome view

I will post this for now,
the rest will appear later
if you cant wait refer to the original knexsayer

Step 4: The Pump

THis is the most distinctive part of the gun, the pump

1 make two of these preferably with black rods
2 this is the firing pin, you should use tape, plus you need the grey rods
3 -7 different pictures of the pump
8 This is the thing that pulls the firing pin back
9 attach these parts to the inner blue rods
10 attach like so
11, this is how it goes in
12. the rubber band goes here
13 finish

Step 5: Stock Portion

kOkay this is the biggest block ever, and I really dont want to take it apart, so I just used some of the pictures from mepains original instructions
Okay bear with my notes, your going to want them, not regret them

1 okay this is my stock, In my opinion my is better because it is more comfy and uses none exotic pieces
2 - 5 more views read the notes
PICTURE 4 IS VERY IMPORTANT, DONT DO WHAT MEPAIN DID
6 - 20 building the stock just do what i did please and dont complain if you didnt
21 the handle
its pretty self explanitory

Step 6: The Top Rail

This is the top of the knexsayer enjoy...

1-3 are all different views
4-5 find and attach
6 -7 make
8 make
9 - 14 make and attach like so

Step 7: The Side Panels

These are mirrored so make two of them, I have pictures of both

1-3 the first one
4-6 the second one

Step 8: Put It All Together

Dont get too excited yet..
I highly recommend you put the rubber bands for the firing pin on now, because it is a pain in the ass to do it later.

1 okay first connect the front portion with the rear portion
2 make sure you have all the grey rods in place!
3 okay this step is a pain, just do it and be patient, also connect the end of that with the trigger via white rod
5 connect the front half
6 connect the grey rod
7 connect the side panels
8 do this one, and the other one
9 YOU ARE DONT

HOOOORRRRRAAAAY
