Part 1, modding the actual gun

This is what you are making:

It's much shinier in real life, stupid camera.

Materials required:
hacksaw
etape
pliers
drill
superglue
silicon lube
screwdriver
screw or bolt that fits your tripod


Open up your RB, the internals are likely to explode.


Take the rubber cap on the end of the spring and rip it off. Then twist and pull the orange piece off.


Streach out the spring a bit and replace both parts.


now take the plunger tube and drill a much larger hole in the center so only the rubber is showing.
You may have to superglue the ruber washer back on after you drill


*This next step is very difficult and risky and I would not recomend doing it unless you are an experienced modder*

When I saw the x-bow stlye plunger head I thought, "Wow, thats got to go", then using the idea from doomsayer, I ripped off the x-bow plunger head and built up a dome of hot glue on the plastic part of the plunger, molding it with a wet finger to make sure it did not go over the sides. I then wrapped it in e-tape and now it has an almost perfect seal. (sorry for lack of pics on this step, I'm doing the write-up after I modded it)
Plunger head ripped off:

What the finished product should look like:



*end warning*

Take the plunger tube and lube it like crazy with silicon lubricant.

Take your chains and repair any damage done to them with long thin strips of duct tape, you should wrap it around the damaged spot multiple times


Cut a multiple 2and1/2in segments of cpvc, wrap wrap them with e-tape, and insert them into the chains


Take a 11/32in drill bit and drill holes in the back of each chain.


Grab your newly finished chain and attach a weight of some kind to the leading end, this stops almost all jamming because it acts as a counter-balance, making it easier for the auto-rotation. I used a roll of tape, I couldn't find anything else.


(If you are going to paint it, skip to part 2 otherwise continue)
Now put everything back together, it's a bitch to close and may take multiple trys.


Just range tested it this morning this is what I got:
(the ranges arent perfectly level for the gun wobbles up and down a little while firing)
9 shots

57'
58'
61'
65'
72'
69'
76'
74'
77'

avg range 67.7'

Here is a video of it firing against my garage door (sorry its kinda dark)


Part 2 painting and mounting on next post.

Part 2 painting and mounting

Take your razor beast shell and protect all the surfaces that come in contact with moving parts.



Paint! I had to use 8 coats of kryon fusion black but, it came out beautiful.


Now grab your tripod


and remove anything but the side-side rotation mechanism.


Drill a hole where this screw would be slightly smaller than the one on your tripod.


Attach the finished RB to the tripod with a screw or a bolt and you are finished!!!



Here it is again:


Questions? comments?

Oh my god. I sold my razorbeast like 2 weeks ago, and now you come out with this. I would do this if I still had a razorbeast. Wow. Mine never got ranges like that. I got MAX 50ft (It was the exact gun that nerfer34 did his etape around the plunger head thing on)

[Bomberman]

Hot Damn! I wish I had a RB. This sounds kind of noobish, but how does a razor beast work? Do you crank that little handle, or do you cock, fire, then turn the handle to advance the chain? But an average of 67 feet does'nt lie. With a ROF like that, man, that is one hell of a gun. I would add a spring, or do a spring replacement, but man, sweet.

~Bomberman

[chefdave]

Adding another spring would probably damgae it, you would have to reinforce it like hell, the streached rb spring is already realy powerfull.

[ompa]

Bomberman, you just crank it and it fires. The crank pulls the plunger back and advances the chain while making a sweet, wonderful, plastic-crunching noise.

[NerfCrazy]

That is awesome. Now I want one. One question how does the hole you drilled for the screw hold up? I would think after a while it wouldn't be so strong. You could probably reinforce it with expanding foam in that little area.

[chefdave]

It holds fine, since there was alrdy a screw there it is kinda reinforced already

[NerfCrazy]

Oh there was? Just goes to show what I know about a rb.

[eddieoctane]

Awesome. Me and my 1 brother both got Razorbeasts one year for Christmas. This brings back memories.

A few thoughts, if drilling the back of the chain does weaken it, could you insert a grommet to reinforce the new opening? A rubber grommet could also help you get a better seal between the end of the plunger and the back of the chain.

Also, could you use a quick-release pin of some kind instead of a bolt to fix the gun on the tripod? That way you could detach it from the base and use it as a portal weapon or mounted turret.

Still, great idea.

[chefdave]

First, the drilling does not weaken the chains
Second, I could do some kind of pin, but the screw takes like 10 seconds to get out with a screwdriver so there is no point
Lastly, The gun is pretty inacurate when not attached to the turret because when you crank it, it shakes like crazy.

[Forsaken angel24]

Awesome work once again.
I proudly add this to the directory.

Yea mine maxed out at 50'. The RZB is just too damn loud.

I'm not sure if I'm buying the 70' ranges but maybe drilling out the holes really do help.

Nice mod, the finished product looks great!

[chefdave]

I will try and get a video up next weekend, the holes massively increase airflow, the new plunger has almost a perfect seal, and I probably streached the spring too much.

[Retiate]

Wow. That's amazing.
Best Razorbeast write up I've seen. Now you just need to get more chains and store them in some kind of ammo box.
