'Nam scenic traps - to build

I am already planning my next trap build, only I have to wait for some parts before I can go ahead.

I have two mortar bomb traps planned - one is a dropping mortar round, and the other is a trip wire connected to a mortar round, as seen below:

Thanks to a reply to a question I asked on TMP I was able to locate some mortar rounds so I could make my traps.

GW makes a sprue of parts for their 40K game, and I was able to locate the sprue going cheat on ebay:

 I ordered two sprues of them, and when they arrive I can start work on the traps.

In the mean time, I bought some cheap MDF sheets (two 60 x 60 cm and one 60 x 120 cm) that I can use for basing bigger pieces of scenery on, and or even make roads or rivers with.
