TR8 updated 6-18-12

my new turret is pictured 1st
it uses blue clips to hold the mini pins in place for easy replacement if they happen to break
no longer do you have to tear apart the entire turret to replace the mini pins!
the blue clip also locks into the underneath blue clip to keep the min pins sturdy and looking clean
i realize everyone doesn't have a million blue clips to spare but if you do this mod is well worth it!

yellow connector on the pin guide is blocking the dark grey connector from going far enough for the trigger to block the ram. any ideas?
KILLERK (author)  ynohtna11 year ago
Show me a few pictures of your gun the firing pin the back of the gun etc... I'll take a look for you an help you out
its a tr18 with tr8 handle trigger and stock. the green/black rod on the trigger is falling out also
KILLERK (author)  ynohtna11 year ago
It's hard to tell but there is a size 64 band from the trigger to the front off the gun this will be the return band an also keep the green rod in place

Few different angles for you of the trigger band wrapped around the red rods on the front of the gun

how is the tr8 better
KILLERK (author)  ynohtna11 year ago
It's a matter of opinion
I love my TR8
I spend a lot of time working on the gun thinking of new ways to make it better
My TR8 has been around for a few years now in that time it has undergone vast changes an improvements
The gun was built then tested then tested some more
I tested the designs personally along side my brother and friends
The gun was battle tested in 3 K'nex wars aka Pandamonium and improved greatly after each encounter
It has proven to be extremely reliable in the harshes conditions of battle
In Pandamonium 2011 last summer my brother who is renowned for breaking the unbreakable had not a single gun problem not one broken firing pin no jams nothing using the current model TR8 with only minor design changes
The current model TR8 is in my opinion the best all around K'nex war gun
It combines the best of ROF range ease of use reliability an yrs of being the best gun ever built
Built it exactly as I have pictured an it will work flawlessly

are you going to post your grenade
KILLERK (author)  ynohtna11 year ago
Idk I think it's simple enough to build did any of my explanations help?
How's your fixes going?
built tr8 ram not reaching turret pics in 3 days
think i built turret wrong
KILLERK (author)  ynohtna11 year ago
K show pics
fixed it and gave it reinforcements
new prob turret pops out when fired took pics but having trouble uploading
KILLERK (author)  ynohtna11 year ago
It's popping out of the black ball socket piece right?
If so replace it with a new one that snaps the turret rod in place nicely
If your still having trouble you can replace the turret rid with a new one
If you can't get ahold of a new black ball socket an you've replaced the turret rod you can always just use a "Y" con to grab ahold of the end on the turret rod instead of the black ball socket
Its more of a pain this way an not as convenient but do what you have to do
Before you try any of that first make sure the turret rod is firmly locked into the black ball socket
This should help let me know
works amazingly well how do you get the light grey connetor on the iron sight to stay on
KILLERK (author)  ynohtna11 year ago
You have to push it down really hard till it snaps in place
KILLERK (author)  ynohtna11 year ago
That rod is held in place by the tension of the rubber band on the trigger so if you don't use or place the right rubber and on correctly then this could cause the rod to slip out

But honestly I really need to see a few pics to help you the more pics the better full gun close ups several angles an ill most likely immediately be able to help you

Also the TR18 an the TR8 have differences that could mess up the guide rods ect... Long story short just get me some pics ;P lol
the grey connectoy on the pin guide also pushes the ram so it stops after the trigger
here is the link i have grey rods instead of black but i am getting more

KILLERK (author)  ynohtna11 year ago
Alright so after looking at the pics I think I figured out why you are having trouble

First off the only thing preventing the green rod from falling out the trigger assembly is the trigger rubber band which applies pressure or "friction" to the assembly keeping the green rod firmly in place
So add a size 64 rubber band to the trigger the way I have pictured

As for why the firing pin won't pull past the trigger block it has everything to due with the length of the back of the firing pin
Basically my pin back is a full connector longer than yours
A simple fix is to simply add 2 blue spacers directly in front of the black ball socket piece on your firing pin however I highly recommend you don't do that and you make my pin which I have never ever had break... It's been over a year dry firing with 6 or 7 bands still holding strong
I'll get you some pictures on how to make it once again it uses a size 64 rubber band which happens to be the rubber band size I use for all working parts on my TR's

I apologize for the older pics but they are up to date enough to get the points across

To make the firing pin
First add 2 or 3 layers of etape around both the rod an the black ball socket connector
Then wrap the rubber band around the firing pin as I have pictured
Then add 2 or 3 layers of etape over it all as pictured in the last picture

If you have any more trouble just message me

Also Im betting once you do these changes the firing pin will not reach the turret but that is due to your attempt to modify my gun lol add my new tr8 turret on the front and make is as I have pictured in my tr8 instructable an you should have no problems

Good luck lol

lol i haven't seen the film let me know how the gun works for you!
Please show me how to make a ram for this! I can't make a ram that doesn't break with more that 2 bands!
KILLERK (author)  Millawi Legend3 years ago
notice the etape is taped over both the ball socket and the rod
the rubberband acts as a cushion and helps hold everything together
the extra etape over the band adds more strength and keeps the band wound tight


the first layer of etape should be 3 thick or so no more than 5
then the band is wound on
and then another 2 to 4 layers of etape over the band
it should be compact still


if made correctly this pin will/should never break eventually it will wear but that is life... you can but shouldn't dryfire the gun with this ram i dry fire it all the time
20101102092257.jpg20101102092349.jpg20101102092422.jpg
why not dryfire?
KILLERK (author)  Fred the evil puppet2 years ago
its kinda the same reason u shouldn't dry fire a bow
every action has an equal an opposite reaction
so the force of the pin going forward without shooting an object has nothing to transfer the energy to other than the pin and the gun itself... the gun an pin are strong however it will wear on the gun an pin much more quickly than if you were shooting projectiles
it just isn't healthy for it lol
