I have a small digital safe pretty useless as far as security is concerned however I would like to use it as the base to make a small fireproof locker. There wont be anything of real value in it, just maybe a bit of inconvienence if lost. I am going to use materials at hand so not going to go and buy special fireproof materials. I was thinking of casing the outside of the safe with a layer of plasterboard, then a layer of plywood, then a layer of plasterboard and finally a layer of 3/4 inch chipboard. Possibly with slight gaps between each layer. I`ll probably have it bolted to a cut to size paving slab to make it heavy. I would like to obtain maybe 1 hour fire proof and not too concerned about water damage.
Feasible or waste of time.
