Always throwin' away chunks of 10ga stainless, any ideas on some plans for a gun safe? Thought I saw it mentioned and did a search on several boards but no luck yet. Don't really feel like shellin' out 30-40 bucks for plans, any suggestions?

Thinkin' about a horizontal safe, double wall with sheetrock insulation, side-swing door on the front, about 2-3ft high, 2ft deep, around 40-48in long with a padlock system similar to a Knackbox. Hey, it'll keep the honest people out...
