While we're on the topic of guns and welding... I had the unfortunate problem of running out of room in my safe (refrigerator size) so I decided to build my own with some scrap I had laying around. Its mainly for storing cheaper firearms and bulk ammo.
Squared up the frame
Put in the shelves and expanded metal siding
Some hangers for a Mossburg 500 and AK-47
Then fabbed up a door, weld on hinges and some paint
Sorry if its a little off-topic, but hopefully the mods will forgive me since there are some pictures with a motorcycle wheel in the back and a few firearms.
