The dripping tap
A new washer cost almost nothing. Finding the right size took three trips to the hardware shop.
Workbench notes
Bike chain
Cleaned and oiled after a winter outside. It still skips in the smallest gear, so a new one is on the list.
Door that sticks
Planed a few millimeters off the bottom edge. Painted it again so the bare wood does not swell.
A wobbly chair
Wood glue and a clamp overnight. Firm again, as long as nobody leans back.
Old radio
The volume knob crackled. Contact cleaner fixed it in a minute, after an hour of opening the case.
