Here's the thing. I tried the L rods many times, and have made sets with bronze rod with copper tubing handles for other people for whom they work fine. I just can't make them work.
Here's an interesting thing, before electric watches, back when they were wind-up or self wind, no mechanical watch in a metal case would last more than days or weeks on my wrist. They'd just crap out.
Here's another thing, many times when some machine won't run, or something isn't working, all I have had to do is the laying on of hands and it starts and runs. That said, I am a pretty good mechanic for anything old enough to not have a computer chip in it. But so many times since I was a little kid, just touching an engine that wouldn't run was enough to put it back in commission. When that doesn't work, I am not a bad trouble shooter and am good with tools.
