Making Las-Plas Razorbacks

The Razorback has become a very common site on the battlefields of the 41st millennium since the advent of the 5th edition marine codices.  With a transport capacity and the ability to put out some good support fire they have become a staple of many marine forces (so much so that I wouldn't be surprised if GW nerfs them in 6th ed so we have to buy new models heh...).  The most popular variants are the Twin-Linked Heavy Bolter, because it comes standard at 40 points and is therefore "free", the Twin-Linked Assault Cannon, and the Lascannon Twin-Linked Plasmagun.  Almost all the variants for the turret are readily available; the TLHB and TLLC come with the Razorback kit, and the TLAC can be bits ordered easily from Land Raider Redeemer/Crusader boxes.  The two variants that are not so easily accessible are the Twin-Linked Heavy Flamer (which is sort of pointless on the Razorback) and the ever popular Lascannon and Twin-Linked Plasmagun variant.  Luckily for us this most popular variant can be converted with relative ease.
To begin with there are two very easy ways to do this.  The first is to simply glue two Plasma Guns together and mount them in one of the small copula spots on the front of the tank.  While easy modeling them this way can get you into some trouble at tournaments with WYSIWYG rules since the gun should be attached to the turret for firing purposes etc.  Personally if you choose to do that conversion I have no problem with it, during tournaments however I would insist you measure to fire the Plasma Gun from the Turret but I certainly wouldn't dock you comp scores etc for it.  The second easy conversion is to simply glue, or in my case, magnetize the TLPG into position in the turret next to the Lascannon.  The reason I magnetize mine is because the Las Cannon and TL PG are separate weapon systems and therefore are not destroyed by a single Weapon Destroyed result but two.  Ok, enough talk let's get started.

Here is what you'll need.
1. A Razorback Kit (or at least the turret assembly including Las Cannons)
2. 2 Rare Earth magnets
3. 2 Plasma Guns
4. 1 Auspex (with or with out hand)
5. Glue, Scalpel, Hobby Saw, the usual.

Trim the handles and stocks off the Plasma Guns, or in the case of the non-primed PG trim off the hands (it came from the Space Wolf Pack box).  Then you'll want to cut the hand or handle off the Auspex leaving you with just the "screen."  Next glue the two Plasma Guns together and glue the Auspex screen to the PG that will be furthest from the Las Cannon.

After that you'll assemble the Lascannon Turret just like the instructions in the Razorback kit describes with the exception of not using the right side (right side while looking head on to the turret).  There is a rectangular part of the Lascannon where the other Lascannon is supposed to fit, since we aren't using the other LC this is where you glue the magnet.  The other magnet gets glued onto the inside of the Auspex screen.  Make sure to check the polarity of the magnets before gluing the last one in place, Rare Earth magnets have both polarities so this is very important.

Once you've done these steps you're practically finished.  All that's left is to assemble the remainder of the Razorback.  If you are like me and want to be able to use the tank as a TL Las Cannon variant then one more simple step is necessary.  Take the right side LC and cut out the rectangular socket section, and cut down the round mount on the weapon support part of the turret.  Leave only about 1/3 of the round "nub."

No magnetization is required for the other LC to be taken on and off.  Two reasons for this.
1. It fits on just fine with out it.
2. It is part of the same weapon system and therefore cannot be independently destroyed like the TL PG can. 
All in all very easy conversions.  Here are some more pics of the final product.  Hope you find this instructive.
