Materials:
Lightning Blitz
20” of PETG
Hot glue
2’ of 1/8” vinyl tubing
2 1/8” barbed vinyl tubing connectors
Mighty putty
Scissors
½” CPVC 90
CPVC
Screw
Rubber Gloves

Reccomended Tools:
Bandsaw
Belt Sander
Hot glue gun
Dremel
Hot water, (sink)
Drill

Alright lets get to the mod…

Here is your stock LB.



Now lets take a look at the internals.



This is it’s tank it’s a backpressure tank, (Obviously to some)



The trigger mechanism.



The pump looks like this.



First will start with plugging the pump although you can't really tell from the picture...



Now we’ll rebarrel our gun.



I used about 4” of PETG, and deburred the edge because I cut it on a bandsaw.

Take out the internals.
Make 2 cuts, here

And here


Now you have to take your 2’ of Vinyl tubing

And 1/8” barbed connector


Put those together by heating up one end of the tubing and sticking it in.
I used a kitchen sink.

Then it should look like this.



Next cut your shell here

And here


DO NOT POST YET!!!!!

[white moonlight]

Now at the end of the handle sand down this ridge


To look like this.


Now take your ¾” CPVC T, and glue it where you shaved out.



Next run the extra tubing through the end of the T facing towards the front of the gun.

Cut off approximately 8” of tubing off of your 2’.

Now connect your store bought tube with your stock pump tube tubing to look like this.



The next step is to cut off your pump handle.
And sand it down with a belt sander.


Take a CPVC elbow and put a ½” piece in one end, and a 4” piece in the other.



Now push some shaved out 1/2” PVC, (3/4”’s) over the ½” of CPVC.

Now slide that over the pump and glue it.


Sorry about the bad pic...

Put the pump in and drill a small hole in the tube.
Then put a screw in and glue it there.



Now hot glue the pump to where you cut off the sticker.
Then internally mighty putty.



Cut 1 ½” of ¾” CPVC.
Stick it in the handle.

Heres your finished internals.



And then screw it back together and your done.



You now have a pump relocated LB.

You can also for personal plessure put a dowell wrapped in E-tap in the
Pump handle/handle.

Questions, Comments, Flames.

P.S. You can post now.

This is pretty cool.

[Soothsayer]

I'm speechless, and not in a good way.

edit:

I'm gonna be straight up. You took a perfectly fine blaster, and relocated the pump very insecurely, and obscurely, making the blaster extremely likely to break and from the looks of this, extremely uncomfortable.

I agree with Soothsayer, I think the LB is a very comfy and non akward gun to pump. You changed all that. And having a T coupler as a handle doesn't seem comfertable. But it is your mod and you did a good job making how you want it.

1. It's very secure.
2. I personally feel it is more comforatable.

If you feel the need to argue with me any more can you take it to PM's please.
If you don't like it don't do it, I liked it so I did it.

Also JATDO the T really doesn't act much like a handle unless you have huge hands.
More of a dowell storage and cleaner channel for the tubing to go through.

I've held the blaster. I also have bigger hands than WML does, and still find the handle perfectly fine. The pump is all about personal preference. It is also pleanty sturdy. Just sayin'...

Carry on.

The LB is one of my favorite blasters so just you having it makes you awesome

The fact that you found a different method to do something is a great thing so props for that too.

This nerf modding thing is all about having fun and doing what you want with your stuff so if you like it and your happy with it that is enough.

Also bonus points for using mighty putty after the death of our fallen comrade Billy Mays.

[Poseidon]

I agree with the previously stated that it looks a little unwieldy at this point. However, I see a lot of potential in this. Perhaps if more of the handle could be kept and the new pump moved upward so it's not hanging out almost in mid air, this would be a lot more usable. Obviously the general masses likes the handle pump, but hey, if you like your LB like your AT2K, then that's your business. Major props on getting the ball rolling though. It'll be interesting to see where this idea takes others.

My one concern with this mod is wear and tear over time. The pump looks cool but after coninued stress from pumping and moving the pumping arm I can see the Mighty Putty breaking off.

[fallinouttadabox]

A problem with this is you lengthened the tubing. The way the LB was designed, the check valve is at the base of the tanks, not on the pump, so by lengthening the tubing you create a pocket of air that can compress without being pushed through the valve. This is going to make it harder/impossible to achieve the same amount of pressure in the tanks. I would suggest putting another check valve right after the pump, or replacing the pump with one that has an attached check valve.

Thanks a lot, and Billy Mays will be missed...
May his products live on.

Thank you very much.
I like the style of pumping for the 2k and I figured I could implement this into one of my personal favorite
airguns.
I hope the same thing will happen with many other guns.

That is considered and I will most likely soon add some extra reinforcement, but right now it is pretty solid.

I didn't even think of that.
Thank you very much for the information, and I will do that as soon as I get the chance.

Also JATDO the T really doesn't act much like a handle unless you have huge hands.
More of a dowell storage and cleaner channel for the tubing to go through.

I'm a little confused, it looks to me like you cut off half the handle, and the T is in the space where the handle was. Unless you're a midget, I'm pretty sure your hands would be all over it.

Did you ever consider swapping in a larger pump? I use mighty putty for all my nerfing needs, but it would be way more stable if you could attach it at two points on the blaster. A longer pump could be attached at the bottom of the handle and that circle thing, plus you would need fewer pumps.

Regardless, I always like to see people doing something different, so nice work there.

If he were to switch it out for a larger pump, he be getting low ranges. Larger pump tube diameter= less pressure= low ranges, but I'm sure you already new that.

Sure I get more stability and less pumps, but also get a lot lower range.
I'm already dealing with pressure issues do to the tubing extension, which I will soon fix.

I guess I should have said longer instead of larger the first time, since increasing the length was the main thing I was wondering about. I've never done a pump replacement myself, but it seems like most people who put longer pumps on their guns seem to get the same pressure in less pumps.

I always thought the deal with wider pumps was just that it was harder to pump once it got nearly full, not that it was impossible to get the same ranges/pressure. Now I now, thanks.

What you originally thought was right. A large diameter pump will allow you too reach the same amount of pressure as with a small diameter pump. However, it is more difficult to pump a larger diameter pump. If you ever pump an Airtech 3000, you will see that it is significantly harder to pump than most other air guns. If you ever use a pump that is very small in diameter, you will see that it is extremely easy to pump.

As for the mod, I always find that if you just keep the pump in the pump tube without anything holding it in, it will constantly fall out and become an annoyance.

I'm a little disappointed. I always loved the outlandish look of the LB.
Well, it is something original. Maybe if it was a little cleaner.

Thats what the screw for...
I also hate it when theres nothing there, and the pump comes out.
The screw has been implemented on this and on my Mega Missile.

I think I'll try and make it cleaner soon, but I'm fine with the way it is.

Any specific reason why the pump is placed at an angle?

Know reason really it's just how it turned out.
Not much of a bother really.

Not bad at all. A couple months ago, I aquired a pumpless LB, so I did something along the lines of this. I then switched it back to having the pump in the grip, because I was worried it would break. I used a BS pump.

Tip: A BS pump makes a good replacement for LBs, as it has no check valve. The LB tank (s) have a check valve built in, so a pump with a check valve isn't necessary. Good use for all those busted pumps all of us have lying around. 10 pumps with a BS pump got me 60-75ft with my LB.

It's really really solid so that shouldn't be a concern by any means.
Thanks for the infromation I think I may have a BS pump lying around.

Oh, and nice socks.

I also think that this seems unstable, but if you say so, I've been wrong before.
