Thread: Securing a pistol safe, wooden house vs concrete floor garage

I fabricated a plate for a friend to go under his floor, what i did was measured between the joists, cut a 6mm plate to fit between them, welded a length of 6mm flat on each side to bolt through into the joists, the tech screwed it in place, sat the safe in place and drilled the floor and marked the plate, i then took it out, drilled the plate, put the 4 10mm lengths of threaded rod in the holes welded up so no way to cut the studs off from below, put the plate with the studs back in under the floor, and bolted it to the joists using 10x50 coach bolts, then sat the safe on top and put nyloc nuts in from inside the safe, then 2x 10x65mm coach bolts into the wall stud on the back of the safe.

I did something similar .as well as the plate I held it up with 200*200 piles I cut to length I think about 860 or thereabouts on the inside of the joists as well . Being old native timber they were spaced about 420 apart so the 400 worked well ,either way it’s very secure . Almost harder drilling through that hardwood than concrete to secure the piles . All held in with rods and coach bolts etc . But just an idea if you are looking to fill any gaps between old native floors .due to the odd spacing by today’s measurements.
I only thought of it after much cutting swearing and bruised knuckles . Of course I had to cut the insulation as well. Nothing is where it should be under old houses .
