Gubbinz: Spikes

Like my shoutas, my spiky gubbinz were originally built toward the beginning of our first campaign.  Although they turned out quite well, there were always a few things I didn't like about them.  Most of it had to do with working with bamboo skewers.  Super glue wouldn't hold them to the plasticard, so I ended up using hot glue, which was a pain to do neatly.  The spikes themselves were also a bit rounded and smooth for Ork engineering.  I envisioned them more as hunks of wothless scrap pounded into jagged shards, rather than uniformly milled metal cones.

Fortunately, I was able to find some plastic cocktail skewers that I was able to cut into various lengths and widths, making for more of the feel I was going for.  I actually had to sand some of the edges down because they would occasionally break off sharp enough to actually cut you.  Most importantly, they could be glued on with plastic cement, which meant that I didn't have to mess with hot glue and I wouldn't have to worry about them falling off in the middle of games anymore.

The other major change I wanted to make to my spikes was to magnetize them.  At this point, most of my gubbinz had been magnetized and my spikes were one of the few bitz still rattling around loose.  Due to their placement, however, installing magnets was kind of tricky.  Whereas the magnets in my boarding planks and boosta rokkits were drilled straight into thick layers of plasticard, there were no places I could do the same on the trakk, especially around the cab.  Without contact all the way around the magnet, the prospect of gluing neodymium magnets to plastic becomes pretty dicey.  Cyanoacrylate glue has pretty low shearing strength and it also doesn't bond well to smooth surfaces.  Neodymium magnets also come together with a lot of force, so magnets snapping together can easily shatter brittle connections.

My solution to the problem was to slice up plasticard tube and encase the magnets in a plastic sheath.  This allowed me to then use plastic cement to glue the little magnetic tubes to other plastic components.  I also put caps on one or both ends which could be used to glue them onto a parallel surface, or to put a buffer between two magnets so as to reduce the impact of them sticking together.  Plasticard gave me the added bonus of a surface that I could write on to mark the polarity of the magnets so I didn't accidentally mount one backwards.  I initially only made enough for my spikes, but I ended up doing the same for the magnets in most of my other gubbinz.  By the time I finished building everything, I'd probably made at least two dozen of these things and I still have a few extras lying around for the next project.

The large spike panels in the back I was able to attach simply by making a backplate that connected through the windows in the trakk's armor.  The front panels were more complicated, as there wasn't enough room for a backplate, nor was there a big enough hole for the magnets to pass through.  I ended up gluing the magnets directly to the chassis and then covering them with green stuff, both to hold them more securely and to make them stand out less.

Overall, I think the new spikes are a significant improvement over the old ones.  I'll probably find a few other uses for those plastic skewers, as well.
