Scratch Built Chimera vs. GW Chimera – Early Build Comparison

    Hello all,

    In my last post I finished building my scratch built Devil Dog.  Scratch building is definitely an inexpensive and rewarding way to bulk up your motor pool, but it begs two major questions: How does it compare to the actual model, and it is really worth the time?

    To answer these questions I picked up a GW Chimera kit.  In this post I hope to answer both of these questions.  I also want to see how far I can stretch the bits in a stock kit to improve the scratch built one.

    I want to stretch the pieces included in the GW kit as far as I can to reduce the work needed on the scratch built tank and possibly improve it at the same time.  I will build most of the GW kit first so that I can figure out which bits are really needed and which ones are extras.

    The Tracks

    The Chimera kit comes with just enough tracks for a full set so I split them into two equal piles and set one aside for the scratch build.

    Chimera Tracks
    Assembling the hull of the Chimera is pretty straightforward, and explained well enough in the GW instructions, so I won’t spend any time on it here.

    I put it together then mounted the half set of tracks, filling in the bottom surfaces but leaving the top open.

    Hiding the Gun Ports

    I’ve never been a huge fan of the lasguns hanging off the sides of the Chimera.  I prefer to think of the passengers firing their own weapons through some firing ports.  Instead of mounting the lasguns that came in the kit I added a piece of sytrene sheet behind the openings.  Without the guns the mounting points look like round firing points.  When I paint this tank I can paint the inside black to represent opened ports, or I could paint them to look like closed shutters.

    Making Some Track Guards

    I’ll cover these open spaces with track guards.  First I use some styrene rod to extend the sides of the track mounts so that the track guards will sit high enough for the tracks to move under them.  Then I glue strips of styrene sheet to these to create some simple track guards.  At the rear there is one track plate fewer than I would like to have.  To avoid having a space I added a simple track plate made from a piece of styrene sheet.  This will be mostly covered by the track guard so I just need something to prevent having a gaping hole.

    Adding Height

    The top and rear hatches simply glue into the voids.  I recommend attaching the top hatch first because it’s easy to drop into the rear compartment, and much easier to fish back out before the rear hatch is glued on.

    Magnet Mounting the Weapons

    The kit comes with two options for the hull mounted weapon, a heavy flamer and a heavy bolter.  I want to magnet mount these to keep my options open.  I could have done this by adding a piece of styrene sheet inside the opening where the weapon mounts.  Then I could have glued a magnet to that and added one to the back side of the weapon mount.  This would have been easier than what I did, but it didn’t occur to me until I’d already glued the hull together :P

    I decided to separate the weapons from their mounts and add magnets at the separation.  The hull mounted weapon comes in two halves.  Before gluing the halves together I cut the gun from the mount.

    Weapon Mounts

    Weapon Mounts Cut
    The heavy bolter and mount are mostly hollow, so I filled the void with some green stuff and glued in the magnets.

    The heavy flamer and mount are solid, but so thin that it was difficult to drill into them without splitting the pieces apart again.  I bulked out the pieces with a little styrene sheet so I could make a hole to mount the magnets into.

    Magnet Backing

    I also magnet mounted the turret weapons.  The kit comes with two turret shields and three weapon options.  One shield fits the heavy bolter option while the other fits the multilaser or heavy flamer option.  I don’t use the heavy flamer option often, so I attached the multilaser to the shield.  I can build a shield for the heavy flamer later on if I decide to add that option.

    I drilled a 1/8″ diameter void and glued a magnet into the cannon mount on the turret, then added a matching void and magnet to the back side of the weapons.  I forgot to take a picture of this, I’ll try to remember to update this with a picture later on.

    The turret can be assembled with the hatch closed or open with a guardsman hanging out of it.  This was an easy opportunity to add some Grot character to the tank, so I swapped the guardsman’s arms with Night Goblin arms and gave him a Goblin head.  There are still some details to be added but at this point the GW kit is mostly finished.

    Size Comparison

    Comparing it to my Devil Dog reveals that my scratch builds have come out slightly larger than the official kit.

    Scratch VS GW Chimera

    This difference isn’t enough to warrant scrapping my previous builds, but I do want to correct the issue going forward.  I scaled down my copy of the Chimera template to more closely match the official model and printed out a fresh set.

    Scratch Building a Chimera

    Building the basic Chimera from the template is essentially the same as building the Devil Dog, so you can see my tutorial on that if you want to know how it was done.

    The Tracks

    For this one I’m using the rest of the tracks from the GW kit instead of making my own.

    The GW tracks have tabs that fit into the track mounts.  Since I’m gluing them to a flat surface I had to cut all of these off.

    Then I glued them to the tank pretty much as I had done for the GW kit.

    Glued On

    I added a couple of simple track plates at the back just as I did for the GW kit.

    Hull Mounted Weapon

    I used the heavy bolter hull mount for the GW kit so I can use the leftover heavy flamer mount for the scratch build.  The template has a base plate to which a scratch build heavy bolter mounts.  I glued this to a piece of cereal box to give it some thickness.  It is the top right piece in the following picture.

    Heavy Bolter Mount

    If you look closely at the picture, you’ll see I’ve already cut a window into this piece, but I left it in place while I took the picture.  The weapon mount fits into this window.  I glued this base plate, and the weapon mount, to the front of the scratch built tank to create the base for a hull mounted weapon.

    Making a Turret

    I built the turret from the template then I used styrene and green stuff to build up a mount for the turret weapon.  I started with a short piece of round tube and cut it lengthwise.  Then I filed it flat until the magnetized weapon from the GW turret would sit correctly on it, drilled a hole for the magnet, and filled the hole with green stuff to hold the magnet in place.  I put a small drop of superglue on the magnet before pushing it into the green stuff.  This left a gap between the turret and weapon shield that was larger than I liked, so I added filler plates to either side of the weapon mount, and filled in the remaining spaces with green stuff.


    Turret On

    Now the weapons I magnetized for the GW kit can be used on both of these models.

    I started building the track guards for the scratch build tank using the same process I used for track guards in part 4 of the Devil Dog tutorial.  I still have quite a bit of work to do on the scratch build, and a little detail work on the GW kit, but they are both far enough along for a side by side comparison.

    Size Comparison

    Scratch VS GW Chimera Size

    Scratch VS GW Chimera Size #2

    With the template scaled down slightly, I was able to create a scratch build with the same width and length as the GW kit and just a tad more height.  Some of the proportions are a bit different but once they’re painted very few people will notice the difference unless it’s pointed out.


    At this point I can say that the GW kit is definitely less work than the scratch build.  I’ve spent about the same amount of time on each of the two models pictured and the scratch build is still missing a lot of the details.  I’d say the scratch build will probably take me three times as long as building and converting the GW kit.

    The GW weapons and tracks are more detailed than the ones I’ve scratch build, and using them saved me a lot of time here.  A complete scratch build probably takes me around four times as long as the GW kit.  If you’re looking for the fastest and easiest way to build your fleet of tanks then you’ll definitely want to buy the models!  On the other hand, scratch building is definitely cheaper.  For the cost one Chimera kit I bought enough material for dozens of tanks.  If you don’t already have the tools you’re probably looking at another $40 or so, but that still gives you an army of tanks for the cost of 2.

    Buying a couple of kits and stretching them, or buying some bits to augment your scratch building is a nice balance between the two.  For my next post I’ll finish the details on these two, and use up some more of the bits that came in the Chimera kit.

    The size difference is barely noticeable. Another great tutorial too.
