I started cleaning and organizing some totes in the garage and I ran across some copper strips I pulled from track lighting awhile back. I thought hum... VW in the REO would be way more fun!
My 3 RM2's built with .7 (my favorite), 1.2 and 1.8 ohm coils that I thought would be a decent test. They all hit the same and surprisingly sounded the same too!
It stays put during battery changes
It was a quick eyeball copper strip bending attempt just to see how well it worked with the different coil resistances. Sometime I'll bend up another copper insert with a few tweaks but this one is working great right now and it removes easily.
Now I get to discover how long 18490's last?
