It occurs to me that what I did might be a badge-bit worthy task, and I did take pictures of the adventure.
Benign deliberate vandalism of Allerton Abbey
When we were staying there as SEPPers in October, the front door was very hard to open or close, because the door had sank down from where it was originally hung. Not sure how much of this was from the building settling, or the door just sagging, but it made the front door somewhat impractical to use, as it was not just hard to operate, but this had gone on long enough such that the door had gouged a sweep into the floor too, so it was limited to about a 60 degree opening swing.
The door was large/heavy enough that I was certain that my wife and I wouldn't be able to remove it to adjust anything, so on the next trip into town, we bought a set of chisels (from Harbor Freight) and upon returning, I tackled paring down the high spots of the threshold, which would at least ease the opening and closing of the door.
At the next morning's boot camp meeting, I confessed to my crime (but the door worked much better afterwards!)
This seems to perfectly fit the spirit and description of "Oddball" tasks, so here it is...
The original door
The depths it has sunk to presently
A combination of loose rocks/gravel from the floor degradation are making it worse
First carefully sweep the area to remove loose debris
Then see where it's binding up and pare it down (first pass)
Second pass
Door is working well enough to open with one hand now. Donate the chisels to the shop, and hope it will be enough to cover the security deposit 😉
