“Do what I did a couple of years ago and add a lobster claw rubber band to the [PowerMate] tuning wheel.”
In case you’re not familiar, Mike is referring to the thick, wide rubber bands that are placed on lobster claws to hold them shut. Mike included the following video; you can see that the rubber band fits perfectly around the top of the tuning knob, giving it a little extra grip.
This same type of rubber band can often be found in the produce department of grocery stores as it’s used to hold bunches of broccoli, asparagus and other produce together.
Many thanks for the tip, Mike!
