We've been working very hard on a major project, which is just beginning to come together now.
In other projects, my husband brought home a chair from somewhere. It is held together by a system of bolts and screws, and about a quarter of them were either not original, or missing entirely. All of the other ones were loose.
I found replacements in our hardware hoard, but had to enlarge one of the holes a bit.
To avoid walking all the way out to the garage to get a drill bit, I ended up carving the hole larger, using a gouge from a set of little chisels that I have.
Then I had trouble getting one of the bolts to go in; a problem that I solved mostly by persistence.
