I would assume a multi-barrel energy weapon would be used to improve firing rate due to recharge rate/barrel degaussing/some other time delay between shots. I would also assume that the barrels wouldn’t have to physically rotate, just cycle the power around them.

At least that’s how it works in my brain.

Perhaps each barrel fires simultaneously, each to the maximum effect that it can withstand due to material strength of the steel of the barrel. Each barrel and focusing lense is guided individually to hit the target together with the other barrels at a distance determined by the central barrel. Basically like crossing the ghostbusters streams . While only three or four barrels are necessary, six are used as extra redundancies due to the weapons getting hot and the fact that the god-machine doesn’t believe in over kill, just underbaked.

The other option is it could be the six barrels create a vortex of energy that channels the central barrels plasma like load of energy to the target making it far more accurate and containing the blast until impact.

Makes me think of the Laser Gun in Serious Sam - four 'barrels' that fire in successsion. It's a sensible suggestion I think, that there's a limit on how fast one barrel can fire, so to increase your rate you need more of them.

Blackadder, I've been following this thread for ages but I don't think I've actually posted in it before now. Your skill, dedication and patience astound me. Well done, it's looking absolutely immense. I can see what you mean with the recent assembled photos - I feel like the gun is maybe hanging a little bit too low, but it's harder to tell without the feet on. Getting the feet on will lift it a little higher and I think the gun height will look a bit better as a result. But even if it's too fixed to adjust now, it still looks great.

Yeah, the multiple barrels would be used for the same reason they're used in the real-world. Heat Dispersion. A single barrel has a certain maximum rate of heat dispersion (possibly helped by active cooling, but still with a ceiling). Therefore, firerate has a physically imposed limit. Adding additional barrels lets you fractionize that fire delay and increase your firerate.

Also, yeah, I don't think that the Hellstorm actually DOES rotate. The art of it doesn't include mechanisms for that. In fact, I don't believe it even has 6 barrels- I think that lowest one is actually just a support strut for everything. You can see in the 'official' art that the rears of the barrels are attached to a square, solidly mounted plate.

"You can see in the 'official' art" Tantalizing statement Anvildude; source, link, Image? It would be greatly appreciated

I may be wrong but....







These all seem to indicate that the lower "barrel" is a support. Though if stats are anything to go by I would say it was a spinning barrel....

Hope this helps in some way.

In the Dawn of War videogames, they show the gun firing, and it fires all the barrels at once.

One thing is for sure, those barrels are not supposed to rotate.

Thanks Cam, Vinter! Yeah, and on the one with the oversized Titan (The 2nd one that Cam posted, that you had a page or two back) it has a square breechplate for the barrels- non-spinning.

So five non-rotating laser cannons, arranged like a gatling cannon.

That saves on some work if you were planning to make the barrels actually rotate!

I agree- it is a heat dispersion method to achieve a higher rate of fire with "light" laser shots. Light in comparison the Titan-killing laser option anyway...

Sleeves:

I tried to find a cement compatible with both styrene and PVC to no avail so I opted to sheath the PVC tubing with 0.020 inch (0,5MM) sheet styrene so to make adhering detail easier later on.

https://i.imgur.com/mOfBr6J.jpg


With a bit of care it's rather easy to do this and although each barrel has six sections the seams will be nigh on invisible once sanded and painted.

What this world needs is a universal plastic cement and I don't mean Cyanoacetate glue.

WELD-ON 2354 is formulated for bonding ABS, styrene (general purpose high impact), acrylics and poly-carbonates to themselves. It should not be used for joining dissimilar materials such as: ABS to styrene, ABS to acrylics, ABS to PVC or PVC to styrene.

its pretty pricey and only comes in pints though so good luck :/

but it seems to be about as universal as it gets.

EDIT Wow im bad at reading. ignore fully. i will leave this up to shame my self.

Double edit: apparently some railroaders say methyl ethyl ketone works for pvc to styrene. but as im in the cancer causing state of america i cant get the stuff to try it out.

I mean, seeing as he's trying to bond PVC to Styrene, it seems it won't work.

Now, what I'm wondering is, if you're making the sheaths anyways, why not make inner sheaths, and faceplates, then take out the PVC and have a much, much lighter tube that you can use?

Yeah, I've tried all these and nothing works satisfactorily and to have a seam open after the work is completed is a drag. It wasn't so much a complaint than a catharsis to rid me of my frustration. I've battled dissimilar materials adhesion through all my scratch-builds and managed to overcome most problems. This is more of an object lesson to would-be builders how to overcome the inequities of life.

As for the inner sleeve we'll see later how I deal with them. Patience.

Once again in spite of the amount of work involved the results are far from breathtaking and I wonder while making up these interim updates that the results are boring to my readers.

Suffice it to say I am pleased how this is coming out

Even in it's rough state with only one barrel mounted the Hellstorm Cannon gives the impression of raw power

And will be a worthy companion to the Plasma Blaster

Don't take a lack of replies as boredom. I think most of us find the build to be very interesting as it is completely out of scope for what most of use would even think of trying to do.

No boredom here, just stuck at work where my company blocks a lot of content, unfortunately your pics get blocked. So I sit at work seeing updates and have to sit in agony till I get home and can see the wonderous progress.

How about JB Weld, or their new JB Weld for plastics? Both are a two-part epoxy I've used with high success, and am very happy with the new plastic weld.

Personally love every update you do, and the wonder at the meticulous detail.

On the glue front, have you tried pipe solvent. I find it works quite well on styrene too, as well as epvc and pvc pipe. Only trouble I have had is being solvent based, if you are a little heavy handed it "melts" thinner styrene sheet materials. But used sparingly has been a good one for me.

My boss likes Oatey's Multipurpose Cement for PVC. But as a cement, it'd probably do fine with multi-material bonding. Then again, it's a little gloppy for your sort of precision.

Has anyone tried using a white glue/water mix to protect the polystyrene, then using something else after? Not sure if it would work for materials under load, but it works for the terrain I am building.
For work, I use a ABS and styrene glue from a company called WELD-ON. Pretty expensive for model work considering it comes in gallons. Also have had luck with using caulking (silicone or polyurethane based)

No boredom here, just AWE.

Hellstorm Energy Weapon

Today it started coming together but the post office delayed leaving the barrel inserts so I can't finish the barrel ends.



They leave hundreds of bucks worth of online orders on the front poach in all kinds of foul weather but 12 bucks worth of toilet paper spools is too precious to leave off unattended; ludicrous!

Yeah I said Toilet Paper Spools; Styrene plastic and spring loaded; I need five of them plus eight for the leg to foot pad stabilizers.

https://i.imgur.com/H8ag4aS.jpg


What else would you use them for goodness sake????

Multiple toilet paper spool holders will probably have you on some sort of government watch list. Hope you didn’t have flight plans for thanksgiving.

Barrel arrangement looks good what overall length did you decide to make Thisbe gun arm?

Spring loaded toilet paper tubes? Please tell me you can load ping-pong balls into the end of this spectacular piece of construction for "realistic plasma action".

This, so much this!

Ingenious use of bits. And +1 on the pingpong balls

Time To Take Stock.....

After a week hiatus I revived with new inspirations on how to proceed. The Lower sixth of the cannon assembly vexed me until I realized where my problem lay. It is pretty much what is found wrong with a majority of scratchbuilds; they are too square and straight sided. The lower rail needed some slight curvature to the sides and base.

Fortunately the material I am using has a taper for ease of extraction from the mould.

Playing on that feature I came up with the correct angles to duplicate the artist's rendering.

This will be more apparent in subsequent images.

Yay! Progress! ... Psst BA ... we've missed you

How heavy is that assault cannon. PVC can start to add up in weight. I might be concerned with the gun arm being able to support that.
