Love those!
Yay, I got some stuff to post again;
My sandblasted and detailed Vigilon
...and I FINALLY got the Storm Bolter finished
(there are a few more pics in my photobucket album)

The Storm Bolter has "stagger fire" just like the Barrel Break (one barrel, then the other depending on how far you pull the trigger at once), and is completely serviceable (almost everything is screwed together).
HOW!!! I need to do that to my vigilon! Also, IIRC you can basically take apart the drum that has the rear facing forwards, and switch it around. Also, I'm genuinely interested to see the inside of those Recon's/Retaliator's to see how you managed to get that stagger system working...
For the Vigilon, I used an enclosed sandblaster on low pressure and took my time removing all the paint. I masked the areas that were already exposed red plastic and just worked on the painted areas. Then I used scotchbrite and some denim rags (i.e. old jeans) to even out the finish.
Do you recall what media you used on low volume for the sandblaster? I've attempted that a few times with meh results. I'd be interested to see what you used, thanks.
Also working on a Steampunk Longstrike now.
