Progress continues and I’m really excited with how the cannon is looking! You can see the detailing is coming along nicely (yes, those are more lifting points on top of the body). I machined up the muzzle today but I’m not 100% sold on it. I machined in three equally spaced muzzle brake slots, but in retrospect a muzzle brake on an energy/plasma weapon probably isn’t the brightest idea 
This shot also débuts my new scale reference: a great little figure from my mate Steve at Mad Robot Miniatures. I’m sure he was quite chuffed with assembling this combination of parts for an Aussie like myself 
The figure is standard 28mm heroic scale, so should give you an idea of just how much of a “big freaking gun” this is!
