I am trying to stick to a schedule of completing a unit per week. Since I finished the Dark Vengeance models, I've been focusing on building the items I already have in house. I am sticking to a moratorium of no purchasing until I clean out many of the shelves/boxes I have of unfinished kits. The Macharius Vulcan was ordered a few years ago and has been sitting around sitting in bubble wrap for some time. Since I've gathered more confidence in my weathering abilities, I figured let's go ahead and pop this guy out, and try a few things.
For the size and detail, the model itself came in just a few pieces with the body being a top and bottom. The sides/tracks were separate parts and the turret was one piece as well. The extra fiddly parts were the twin-linked heavy stubber (three parts), the two exhaust pipes, three pieces for each sponson (flamer or heavy bolter or stubbers), engine cover, two cupola covers, and the extra tracks sitting at the back of the tank. Being resin, there was some warped spots with the stubber a bit crooked (still), and the chassis itself. I soaked the entire body into very hot water and fit it together until it cooled. It went together quite easily afterward.
I wanted to stick to a basic grey. Using my airbrush, over a black primer, I sprayed Mechanicus Standard Grey, then added a touch of Fortress Grey, then a light flesh color. I tried to follow the steps utilized in the Forge World Masterclass's Earthshaker Emplacement. I then painted basic colors onto any metal parts or items of such, weathered it, and sealed with a gloss coat. An oil wash was then used and dragged down the side of the tank or blended on the horizontal surfaces with a brush using thinner. Since the vehicle was sealed, the original paint is protected from the thinner and the gloss really helps the oil paint to spread freely over the model.
The main thing to practice with weathering is to do it in layers. Complete a layer, let it dry, then add another layer, and maybe another if desired. A single step of weathering can have a good effect, but if you were to add another and another layer, you then get a more realistic look and feel to the vehicle. Much like I stress the three layer effect of painting, base-shade-highlight, you want to follow multiple layers with vehicles and tanks too. Part of this was accomplished with the lightening of the base colors during the original airbrushing. The sponge effect was used to add paint chips and the weathering with oil paints and pastels over the top of that.
Finishing a tank of this size and detail to this level really encourages me. I experimented with more weathering. Future floor wax was used to get an oily effect as well. What you really want to accomplish with each kit is to try a new technique or work on a difficult one to push and increase your abilities. With what I gained here, I plan to bring out and build my three Baneblade variants I've been sitting on since not too long after Apocalypse first came out. But first, I have to finish my Command Squads...
