That would be a good idea but for me it would be too much of a hassle working with concrete.
I actually would like some input on the door handle. I will post pictures Monday of the handle but I am trying to figure out way to attach the handle to the locking mechanism without having the weld it together. After I get the sheet metal on there, it will be almost impossible to get inside there and weld it. Plus if something had broke in the future I would like to be able to take apart the door.
I was thinking of making a hexagon sleeve or even a square sleeve that the handle would slide into. Im going to play around with a software I have so I can explain that a little better.
