It's easy to get so busy that you don't spend as much time with your children as you would like. We have a lot of used bicycles, which supplies me with enough parts to make enough for each child to have a working one.
The problem has been that I didn't have good repair methods, so only a few bicycles are ever working at a time. Now, however, I have set up an easy and efficient bicycle repair station in the carport. Most of the stuff was already there, the only real addition was the half drum with water. What I have is: the half drum/barrel with water for testing inner tubes, a sitting/standing stool for sitting closer to the ground than a chair would allow, a ratchet and sockets, a few wrenches, several tire spoons, a can of spray lubricant, a little tub of grease, a package of tube patches, and an air compressor.
You could replace the compressor with a tire pump, and I found that the patches with the little tube of glue work better than the newer style that has adhesive already applied. This is actually starting to be fun, and at the end of the day, I feel like a million bucks, knowing I've fulfilled part of my role as a father.
