First I start with a rough sketch of how I want the base to look.
Once I am fairly satisfied, I begin by gathering materials, in this case, since I am after a bombed out room of a concrete building, and the scale is fairly large, I like to use sheetroock that has had the paper removed on both sides. A warm water soak and some elbow grease does the trick.
Then using my sketch as a guide, I do a mock up of the scene that I want to portray as seen below.
Once I am satisfied with this, I measure the mock up and cut the base, in this case particle board.
I then take a picture so I can use it for reference when permanently attaching the material to my base, pretty standard stuff.
Now the fun part! Once I am ready to transfer everything over, I give the surface of the base a good coat of straight white glue.
I then begin placing the smaller pieces on first, followed by the larger ones until I get it just right. The larger upright wall portions in the rear of the base get some extra white glue.
Next I spray this with a diluted mix of water and white glue and everything is set to dry overnight.
Once set, I again give it another spray with the white glue mixture and allow this to dry. I the seal the material to the outer edges of the base by tooling in a bead of 5 minute epoxy all the way around.
After this dries, I give it a light coat of spray adhesive and sprinkle some fine ground sheetrock and sheetrock sanding dust. I apply this in select areas only.
The rebar pins are made from appropriately gauged wire. The notches are made by gently squeezing the wire cutters in incremental distances the length of the wire.
I wanted to have some really gnarled bent rebar so you want to make all of your bends first before you indent it, else the wire will break or bend straight at the indentions.
I drilled some micro holes in the locations I wanted the rebar, including through the chunks of "concrete" still attached. A small drop of CA into the holes and the rebar is ready to insert.
I then attached small pieces of shaved gnarled wood. You don't have to get too neat here. I just use a sharp utility knife and a 1 x 6 pine board and shave off appropriately scaled pieces. You will be surprised how realistic you can make splintered boards using this technique.
It is difficult to see, but there is some twisted gnarled sheet metal in the scene also. I make this by taking a length of solder and laying it on the concrete floor. Use a torch to melt it and the flat of a hammer to mash it out. Once cooled, you have some really gnarly, damaged looking metal that can be twisted and formed to the desired shape to suit your needs.
Here are the results so far.
Next, I sparayed the whole assembly with a coat of flat black for shadow and then light grey. Once dried, I gave another shot of flat black to areas of the walls that I wanted to look "burned".
Then I detail painted all of the bits of wood and metal and rebar with varying shades, drybrushing lighter with each step. Rust and some silver for the metal, some browns and reds for the wood ( I added the reds to flat parts of the wood only to represent some paint still present) and black, rust and steel to the rebar.
A note about rebar, or concrete reinforcing rod. For those who have been around or worked with it, you know that it rusts something fierce!! I have torn out concrete with rebar and even buried in the walls, if it wasn't rusty going in, it is definitely rusty when it comes out!! Alot of elemental occurences would cause this but most likely, just the moisture in the concrete when it is poured is the major suspect. So make sure if you model rebar to rust it up!!
Finally, I adressed the concrete itself by drybrushing some earth shades and many different greys to eventually wind up with this.
All that is left is to add the figure (when it is done) and weather with some pastels.
Oh yeah, the propaganda poster is suitable for the scene. It is for the Volksturm, a Nazi attempt to call on the last reserves. The caption translates to "Freedom for Life".
The base will get some nice wood trim applied and one of our custom acrylic cases. This will be a belated Christmas present for my older brother who is a wonderful modeler and figure painter in his own rite and used to build me such when I was a kid. It is time for me to repay the favor!!
I am trying to get him back into modeling but he know paints digital aircraft. He did the plane for the new movie Flight of the Phoenix so I know it keeps him busy but I will keep twisting his arm to join the big-A.
For those that may be hesitant about building a base for your figures, don't be!! It adds so much more to the appearance and really is not that hard even for beginners. There is a wealth of knowledge here on Armorama and I hope I help by giving back a little.
Thanks for looking and enjoy!!
