One of the things I like to do is convert Epic miniatures. Because of their size, and gaps in the miniature range, conversions are easy. The plastic material is soft, and details can easily be added from other miniatures or sheet and rod plastic stock. Most conversions are easy, hence my BattleForce is mainly composed of Mk6 Marines. My most ambitious conversion is of course Marneus Calgar, Master of the UltraMarines. His pose is copied from the metal 28mm Jes Goodwin sculpture, so it will be instantly recognizable on the battlefield.
