So with the Waaagh GT a mere 10 months away, I decided I needed to get EVERYTHING ready for my army painted STAT. That includes getting the Vendetta ready for action. But I also realized that you need to magnetize the Valkarie because what happens if GW decides that vehicles aren't as important in their next edition of 40k? Well with that, I looked around a few sites that do this kind of conversion and magnetization, and here is my contribution:
First of all, the multilaser in front needed to be swapped for a twin linked lascannon. I'm assuming for now that I won't have just a single lascannon on the front of this thing. Since with the side pods, you get 3 options for the spotlight, I used a trick where you reverse one of them and place it on the back side of the weapon pod thusly:

The 0.135 x 0.03" rare earth magnets I used for this project were just a tad too weak, so I generally had to double them up. On this particular piece, I used only 2, but there was plenty of space so not a big deal.
Next the lascannon and multilaser were magnetized:The top half of the twin linked lascannon was cut down from a triple pack of regular guard las cannons that I bought from www.thewarstore.com. Nice and cheap, they look the same, and you'll see what I did with the other 4 lascannons soon enough..

Here you can see the connected lascannons to the side pod. The magnets touch and are quite strong.

Here's a shot of the side pod glued onto the Valkarie body:

One problem with doing two magnets is you have to worry about polarity, so to make sure that they were correct, I mounted everything using multiple magnets while the super glue dried:

After the glue is dried, the pieces can be pulled apart easily, and I KNOW for certain that the weapons attached to them will face the right way.
Below is a shot of the weapon pieces. The missile and the rocket pod are fairly straight forward. You just have to carve down the top pieces a bit until you have nice flat surfaces to glue the magnets to. The lascannons are ground down to that they glue evenly to each other, and then I tried to glue a stryene tube with a paper clip inside it to the top. That sucked as the magnets were not strong enough, so I cut it in half and glued the magnets to it. It looks messy, but should paint up fine.


Here's the rocket pod and lascannons mounted to the wing. It looks pretty sweet if I do say so myself. You may notice there are 3 magnets on the wing. This is because the magnets weren't strong enough (it was flimsy, and I want my connections strong), so I had 2 magnets mounted to the wing sponson.

And here's the full weapon loadout on the Vendetta/Valk conversion. You'll notice first that the wings aren't glued on yet. That is because I'm trying to decide whether to magnetize them or just leave them detached for easier transport. The slots are very firm and easy to put the wings in, so may not need magnets. Also notice that the top has not been glued on. I did this to be able to paint the inside more easily. For this build I'm not planning on using the side bolter gunners, but I'll have them and magnetize them if necessary. Also the back ramp has magnets so that it can be closed easily (I think it might get loose after a while, so you gotta think ahead!)

That's it for now. I'll start painting this baby in the next few weeks, although I also want to get my Ogryn Turret conversion greenstuffed. I need to figure out how to do sandbags in greenstuff first though...
