If you haven't watched any of Adam Savage's One Day Builds on Tested, better do so when you find free time. Here is one epiosde where he builds a custom NERF Rifle... "This past holiday, Adam took part in Imgur's secret santa gift exchange, surprising a fan with a custom modded and painted Nerf rifle! For today's One Day Build, Adam shows how he took the Nerf toy apart and put it back together with his functional and aesthetic improvements."
