When I was a freshman in college, back in 1963, I had a 1958 Harley Davidson 165 motorcycle, one of HD's 2-stroke wonders. It wasn't a great motorcycle, by any means, but it ran. Well, I had occasion to remove its cylinder head to replace its burnt-out gasket. The parts guy at the H-D store told me what the torque was for the nuts on the studs for that cylinder head. I nodded and took note of that.

I understood what inch-pounds meant, but had no torque wrench. All I had was a 1/4" drive socket set my father had given me. It came with a 6" long breaker bar that had a hole at the end of the handle. If I remember correctly, the nut on the head was a 1/2" hex, so the stud must have been 5/16". I don't remember what the torque specification was.

My roommate in the dorm was an avid angler. I asked him if he had a scale for weighing fish, and if I could borrow it. He said yes.

So, I borrowed his fish scale and calculated the force needed, given the 5.5" distance between the center of the socket and the hole in the breaker bar handle. I hooked the fish scale into the breaker bar handle and torqued those little head nuts to specification by pulling the fish scale.

Where there's a will, there's a way, I guess. In reality, just tightening those nuts by feel to about the same torque would probably have worked just fine, but I did what I was told to do, despite not owning a torque wrench.

Must do? Make do.

Here's the idea:

I had plans for a bathroom scale, road salt bags, and my **** for my semi truck but decided to make it easier on myself and get a real torque wrench since it was tax deductible.

18-year-old college freshmen don't pay taxes, usually. I had zero money, really. I had to borrow money from my roommate to buy the stupid head gasket. :ROFLMAO:
