I am starting the project of building my stormlord for my sisters of battle. I don't plan on too many mods to the standard design. The main difference will be swapping the lascannons for Multi-meltas on the sponsons (to keep with the holy trinity of armaments) and building the exorcist missile launcher that will fit on the top of hull. I also have plenty of immolator bits to embellish the stormlord to give it a more sisters feel.
So far I have started with the most ambitious part of the project: building the exorcist missile launcher from plasticard and tubing. So far so good. I have a snug fit with the basic mount and have built the first row of missile tubes. I went with the gawdy organ style missiles for weapons mount. I have shortened the tubes from the original exorcist (the first center back one is only 4cm and gets smaller in .5cm increments).
I used the large blast template to get the arch for the missile curve. I'm happy with it. I dread making the next row. The back row was a lot of work to get the heights and angles on the tips of the launchers (measured .75cm to get a consistent angle for the tubes).
I will probably leave the mount unglued as the data sheet will make the exorcist launcher optional. Part of the data sheet will state that the adepta sororitas stormlord's "all power to weapons" rule may also apply to the exorcist launcher. Now that would be fun!
I had to know this part of the project would work before I would continue. Once the launchers are fixed I will add plating and rivets to make it appear more natural to the rest of the structure.
I will also need to figure out what multi-melta bits will work best and figure out the best way to mount them on the top sponsons.
I will try to keep this post updated a few times a week.
