Here's the other part of my addition to my Space Sharks force for the 750pt level in the local escalation league (along with the bike captain), a Whirlwind. Whoosh, boom.
The launcher sections fit together pretty well without glue, so I left them that way. I did glue a spare die to the bottom of the swivel-piece to help weigh it down. Should make weapon destroyed results or Rhino conversions easier.
