Know any old Barracks / airbases being demolished or gutted? The site manager might be willing to do a deal. They were very accommodating in Colly and a crisp tenner secured a Belfast sink, oak window frames and some lead (which was free as I stole it during the night). Might be worth a try.
Cost and time, I can get a grille shipped tomorrow for 100 notes and the work done including my existing door shifted for the same amount again!
I need to get this done quickly after finding that Plod HQ had sat on my RFD application for 4 months and not given me the go ahead to get the work done. Auction season is around the corner and I need to get a lick on!
What 5A said, get a fabricator welder on your side, they will tell you exactly what is possible, a 2" angle iron frame with ten good anchors 3 to each side and 2 up 2 down. Welded hinges supporting a 1/2" plate door. I have seen similar blast doors in places I have worked.
If the reveal is deep enough, you can repeat the process in timber and architrave to create a doorframe that fits in with the house.
Thanks I've tried most of them and none of them are narrow enough. Spoke to my FEO about it and he agreed that a good door opening outwards and a bfo security grille opening inwards seemed sensible. Up to the cpo to agree that it would be enough.
The downside of having one door opening in and one outwards is that you lose a load of space on both sides.
Would you be able to set up a lightweight timber over-door (hung with heavy duty concealed hinges) in the style of a fridge in a fitted kitchen? It would allow the outer timber door to open "away from the door frame" and then let you at the inner door which could also open outwards.
