[Archive] Earth Shaker Cannon WIP

Tarrakk Blackhand:

Here’s my home made Chaos Dwarf Earth Shaker Cannon Work-In-Progress.

I built this using the two white plastic rings which came from a styrene sprue runner. I can’t remeber what was on the runner in the rings, but the rings remained.

Once the rings were cut from the sprue and reshaped, I then cut and rolled a flat piece of sheet styrene, placed it between the two rings and glued it in place. It was at this point I discovered that the two rings were different sizes, therefore the cannon tapers.

The cannon was then “Skined” with Plastruct HO scale roof tiles, making sure that all the curved edges of the tiles pointed forward.

The outer A frame was built using 1/8"x1/8" square beams cut at a 45% angle.

The front ring of the cannon was cut to shape and drilled open using a 3/8" hole cutter drill.

The end of the cannon is a front nacelle cap from an old AMT U.S.S. Enterprise model kit that I cut down so that only the ball and inital taper remained. Without measuring and by total fluke, it turned out to be the perfect fit for my cannon.

More details will be added including a set of working gears so that I can position the angle of the cannon by turning the gear crank.


cool earthshaker, cant wait to see it finished with crew

Tarrakk Blackhand:

Crew will be a problem. I ran out of Dwarf mini’s. Someone said they were going to give me their BFSP Dwarfs as they were not going to use them, so hopefully they can do that soon. Otherwise I might just temporarilly man this with “Good Dwarfs”.


Great looking earth shaker, i like the fact its not on wheels it makes it look like a huge siege cannon, looking gorward to seeing it finished :slight_smile:

Tarrakk Blackhand:

i like the fact its not on wheels

Wheels are actually part of the equation. The CD's need some way to bring it onto battle. I was going to make a base for the A-Arms and then use some Cragar 5 star mag wheels from a 1964 Chevy Impala model kit. HEY! you need style, right? :D


Use shields for wheels, and then just stick at least 6 on the side (:

Oh and ofcourse: I like the model a lot, better than my kindersuprise cannon good luck painting it.


Woah, that is some serious pinning there!  The body swaps won’t be going anywhere, that’s for sure.

I really like the smoke effect on your BB’s.  When I eventually get a proper unit made I will seriously consider doing that on mine.

Your earthshaker, will you be giving it wheels or not? Edit. Already answered :~

Tarrakk Blackhand:

ThanX Grim. The “smoke effect” is only a black wash and the smoke itself is cotton.

Tarrakk Blackhand:

Some new photos for you!

Here’s the cannon with the inner barrel attached. I also added the gears from an old tape cassette recorder so that I could position the cannon by turning a crank.

The back end of the cannon. A Chaos Maurauder shield acts as a loading door and a model train break wheel acts as the opening mechanism for that door.    

The primered cannon just after I sprayed it. The paint is still wet in this photo. Note the Dwarf Buckler Shield on the side of the barrel. I used them for spacers between the gears and A arms.  

The two gear mechanism for adjusting the barrel height. Both gears are from the broken Cassette Deck.

The reverse side of the mechanism. Note the crossed bone adjustment wheel. This was taken from an old Vampire Counts shield decoration.


Great use of bits, your heartshaker is ace!

Tarrakk Blackhand:

ThanX Bassman!

There’s still alot to do on it though. The Cannon Barrel and A arms are finished from a model point of view, but I still have to mount it on a mobile base so that the CD’s can push it into battle. But with the cannon still in wet paint, I can’t start work on the base. I need the cannon to space it correctly.


Great job man!! Keep us updated.


I really like your gun and I’d like to give a couple of suggestions:
add rivits to the carriage, a little touch that add a lot of realism to the model.

Join the two parts of the carriage with a couple of transversal bars (four would be optimal) to give the idea of a solid and sturdy carriage.

You can lay it on the ground or give wheels, as you prefer.
If you go the wheel way, I’d suggest you 6 wheels in total, it looks very heavy!

Could you place a dwarf next to the beast to see how large it is?


Tarrakk Blackhand:

Here’s the Cannon platform before painting it. I had to leave one of the A frames off in order to do paint work on the cannon itself.

Note the textured plate. that’s more Plastruct sheet.

The other side of the Cannon’s base.


I like the idea of a platform but, sorry to tell you, I do not like the Plastruct sheet: it’s too tech! It’s a fantasy army, not 40k. I would be better if you left bars of metal or, if you preferred a platform, wooden panels.

The rest of the build is super :slight_smile:

Tarrakk Blackhand:

As Scotty said to McCoy in Star Trek 4 when McCoy asked Scotty about him giving the secret of transperant Aluminum to the owner of the Plexiglass factory -

“How do ya know this isn’t the guy who invented it?”


Ishkur Cinderhat:

Wow I like how the roof tiles work to turn the surface into something resembling Chaos Dwarf scale armour. :hat off

Will the the crank mechanism you mentioned actually be working in the end?

Tarrakk Blackhand:

Yes, the gears work. I have the model painted up and “Finished” with exception to crew. I ran out of Dwarf models, but one of my customers is giving me his BFSP Dwarfs sometime soon and those guys should be able to handle it…with a little conversion.

Tarrakk Blackhand:

Ok, here’s the finished Earthshaker Cannon. I still have to find crew for it, but for now, one of my Death Rocket crew will show you how it works.

The working gears in action. They are strong enough to keep the cannon in this position (or any other) by turning the hand crank.

The barrel has a brass outer housing and the rear of the cannon is copper plated to help with cooling as copper takes more heat to melt than Cast Iron.

The awesome Earth Shaker firing a deadly shell.

The Chaos Dwarf weaponsmith standing beside the mighty cannon.

Ishkur Cinderhat:

Wow, a working gear, this has got to be the ultimate torture for any opponent, to see the barrel being adjusted to fire the next round. :wink:

Tarrakk Blackhand
Are you sure? Because Wikipedia states that Copper has a melting point of 1084.62°C while cast iron has one of 1150-1200°C depending on the alloy composition.

I just had to look this up, but I find your thinking behind the painting of the model awesome nonetheless. :hat off
