What’s a Ratchet?

His electronic peddler (that he had been using almost non-stop for spasticity release for the past three years) recently bit the dust.  We had taped it up with duct tape, oiled all visible parts, and my solution, jiggled it unmercifully, with no success.  Resuscitation attempts of the old one were “called” and we had to pull out our backup peddler.  Unfortunately, when we turned on the backup, this terrible grinding noise could be heard with every rotation.  Since the grinding seemed to be coming from the motor, Lynn’s recommendation was to order a new one and return the noisy one when it came in.  So I did.  Well, the new one isn’t noisy but it has a hitch in its giddy-up.  Every rotation now is accompanied by a shimmy jump that can be felt in the base of Lynn’s foot and all the way up the leg. Upon watching the action for a period of time, he made the pronouncement, “I don’t think the arm is tight enough.  You need to tighten up the bolt. Go get the ratchet.”
Hearing the, “Go get…” was like a Pavlovian response for me.  My skin became clammy; I developed tunnel vision, and the muscles in my head and neck tightened.  It happened to be raining yesterday so my arthritic hands were already screaming with every use. “Wait a minute.  I can’t tighten anything today,” I responded. “My hands hurt, too, much.”
“It will be okay. The ratchet will do all the work.”
To myself, I’m mumbling, sure, that’s what you always say but outwardly, I’m saying, “okay, I’ll give it a try.”  So, off I go in search of a ratchet.
Lynn has not been in the garage in at least five years.  During that time, many of his friends, our kids, and I have gone into the garage to use his tools.  He remembers the tools being right where he last saw them. That’s not exactly true anymore so the first thing I have to do is search for and locate this item that I don’t know what is.  He describes it as a long silver tool with a thing like a bolt sticking out the side at the end of it.  I start looking under things, opening all the drawers in the toolbox, moving things around, and piling them into new heaps (that will again cause confusion in the future because they have again been moved), until finally, I find three silver things that match the description.  “Is this it?” I ask my mentor.
“Yes,” he responds, “but you also need the sockets.”
“Okay, what are those and why didn’t you mention that before?”
“Those are small silver round things that you put on the bolt and which inserts into the racket.  There is a metal strip out there that has what you need on it.”
He doesn’t answer my question about why he didn’t tell me this the first time and I proceed to look for sockets.  I find a metal strip with silver things that match his description.  At least half of the slots are empty so I look through drawers again finding similar items and again return to Lynn.
“Where’re all the sockets that belong on the strip?”
“Who knows?  I told you things have been moved around. This is all I can find. Okay.  What now?”
Lynn proceeds to tell me how to remove the protective cap covering the bolt on the arm of the peddler. Then we go through how to select the correct size.  I try to figure out how to attach the socket to the racket finally being successful after multiple attempts to push it into place. I put it on the bolt wrong, feeling totally inferior as a mechanic.  It doesn’t work so I try it the other way and it works!  After multiple, painful, tightening attempts, the arm of the peddler seems tighter and the squeak that was accompanying the giddy-up hop goes away. Triumph!
