My dad and I are going to be under going a project of converting a good sized closet into a fireproof gun safe, has anyone else here done this? If so any advice. Our plan is to take a basement closet with a concrete floor and lay brick on the interior walls. Then we plan on taking 3/8 steel plate and laying that on the floor and wall inside the brick and welding the seams. how does this sound? all advice is appreciated.
