My life sized warhammer 40k chainsword replica. Made from pink foam, fiberglass, MDF, styrene, resin, bass wood, pvc and lots of hard work! It took about 4 weeks to build, weighs about 4lbs, and measures 37" long.

If you want to see a tutorial on how this was made check out my blog for lots of in progress shots and descriptions -
