"Some of the thicker pieces on the brickarms weapons need some help cutting through with a pair of good pliers. Use an xacto knife to score around the area you want cut off, then hold the piece with pliers and push back and forth on the rest of the gun with your hands. This should get the piece to slow break off along the lines of your cuts.

I use a heated razor blade to score along a cut line, then use an xacto knife to make the cut and glue everything on with Super Glue brand "thick gel super glue". I find that regular super glue doesn't work, the thick gel type is much better and bonds quicker.

My friend, whom I play lego wars with, created an RPG that apparently shoots chain-shovels. He states you can never have enough 'chain-shovel shooting' in a lego war."
