About two years ago I started diging into the side of a hill with the frontend loader on my little tractor now after working my a** off every weekend I'm almost done I poured the top on my 12'x40' bug in bunker last weekend and I was hoping some of ya'll could help me with ideas for the front door and hinges I have scrounged most of the building materials and can't afford to get a store bought bunker door any advice would be greatly appreaceted. I'll try to post some pics if I can figure out how.

The door from an old bank vault, including the frame, of course. Heavy duty. Kinda obvious, if that's a concern.

One thing I would suggest would be to put a U bend oriented at 90 degrees to the line of the entrance of the bunker so that you have corners you can defend if intruders should follow you into the main entrance.

This will also allow you to bottleneck them in the entrance tunnel while you send backup out the emergency exit to hit them from behind.

Something else that occurs is that you will need to compact the soil as you backfill or as the soil settles naturally it will leave a shallow dip in the ground surface that can show up the position of your bunker. Quite a few new build German coast defences where spotted this way during the recon prior to D-day.

As for the door something that was used as a defensive measure in British bunkers during WW2 was having 2 six to eight inch layer sand filled cavities on the outside of the exterior bunker doors as a bullet and blast absorber.

Wow! I'm so impressed with your ingenuity to make this from scrounged materials! I know we cannot afford a pre-made bunker with the works, heck, not even an old school bus right now, so I find your project inspiring to say the least! It seems the pre-made bunkers are just another thing that delineates the haves from the have-nots.

Will you be leaving the roof flat or putting something over it that is curved?

@prepgirl, Thanks and your right premade bunkers are for the rich but if you try hard enough you can do just about any thing. Look around you will be surprised at what people throw away, go down to your local scrap yard you will find piles of rebar,angle iron and I beams for the cost of scrap metal ie. my vent pipes are old 4" fence posts find someone tearing down an old building not only can you get stuff for free I've been paid to haul stuff off. As far as the curved top you can't see it in the pics but it is about 2" higher in the middle than the sides and from back to front the whole thing drops about 3" so water shouldn't be a problem.
