So I started out with my favorite 8" tongue depressors which would give me a good amount of space to work with and the proper length for the trenches all in one.
From there I cut 1/2 inch pink foam into 8 inch strips that were 1cm wide... Yeah I'm a dual citizen so I can use imperial and metric at the same time... From there I glued these down onto the tongue depressors fairly centrally.
Be careful not to use too much hot glue or get sloppy with it as you'll have to clean up the excess hot glue later. You can see there is a bit of glue that got all over on these. Made my life more fun by having to get in there with a knife and clean it all up to fit the wood barriers and front edge of 'soil'.
From there I trimmed off the top corner. Having done this a bunch of times I can tell you that accuracy is not necessary but helps. Trimming down the top to the half way mark also provides you with the perfect filler for the front of the trench soil.
Taking that front piece and gluing it down with a healthy amount of hot glue gives you the perfect frontage for the trench line.
So you can see you end up with overhang. The depressors wood edge is perfect to follow with a knife. Trim the edges and you are ready for the next step.
I used a sawing motion with the knife and received a clean edge without 'gouging' the foam with a dull point in the knife.
Sanding down the font made a nice and cohesive surface that would take glue and sand well. Propping something up under the sandpaper can also help you achieve any special effect or shape in the sanding process. Being to rough can lead to the foam catching and breaking off so be careful.
Here is an example of that happening along the corner. You can either leave it as a battle scared trench or fill it in.
I just took the piece and hit it with a ton of glue and packed the foam back in and then after it had cooled gently sanded it again to bring it back to the nice soft edge I wanted.
So for the backing of the trench I wanted a classic supported wall with wood beams that would have been commonly used to reinforce the trench from collapse. Simple method, found 8" dowels, stacked them in along one of the trench pieces and found that 7 was the height of the trench and then cut upright pieces to the appropriate height, you can see them in the right hand side of the picture above.
From there it was simple enough to hold the dowels together tightly while putting a bead of hot glue down them and then pressing the upright into the glue and waiting for it to cool.
Repeating three or more times per backing ensured I had a solid piece that would look the part.
I hit the back of the trench with a healthy zigzag of hot glue for a solid connection.
And then held it in place until it had cooled, checking to make sure that it was solidly on and wasn't going anywhere.
This part went fast and only minor trimming/sanding was needed to make sure that the backs matched up with the trenches.
From there I flocked the model before painting and snapped a few pics.
From there a little paint and static grass and the trenches were done.
The beveled edges that they have from the tongue depressors really make the versatile in their deployment as the just rock off one another. I'm thinking of doing up 20+ of these and making an epic defensive force(not that it will be epic in its amazing game play, just the amount of digging it would have taken to make).
And now to find another project.
Until next time.
