I completed the test barrels and pallet. They turned out pretty well as a test. I am still trying to decide if I want to stick with the 4 barrel setup or if I want to go with a 9 barrel cluster. The smaller setup is a little easier to work with but it is a little small for a 40mm base to sit on. Either way I now have 2 new molds to make, 1 for the pallet an one for the barrels.
The painting on these was dirt simple, just a silver primer and blue top coat. I then dipped them. When they were dry I hit them with a boltgun metal and browwn/orange mix to give them a little weathering. If only the rest of the army was this easy to paint.
