I managed to pick up a couple of Land Raiders very cheaply on Ebay. One will be finding itself refurbished properly and added into my Imperial Guard army as an allied unit (I have started writing the fluff for that one), the other one is being turned into terrain.
Stage 1 - close assault on a Land Raider with a tenon saw. As you will see, it's basically a hulk; most of the weapons and hatches are missing and I'll replace some from the bits box.
Stage 2 - the bases are cut from 6mm MDF, the Land Raider parts are stuck down with plenty of hot glue. The larger part will be painted as a Blood Angel vehicle, so I'll do the basing in standard grass colours. The smaller part will go into my Mars terrain so I will probably paint it up in Ultramarine colours to clash with the red basing.
Stage 3 - hatches replaced, weaponry replaced, I will add some torn-away wiring to the right sponson where I'm not going to put a new gun in place but basically I can sand the base and start painting once it's all dried.
