Disclaimer: Do this at your own risk. I have spare parts in case it didn't work and even then didn't decide to pull the trigger and try it till I had messed with it for a few hours. I nor ECF endorse this mod. It's for informational purposes only.
The objective for me was getting a solid brass/silver/or aluminum contact to maximize conductivity vs a point of a bar with minimal modifications to the original design.
So it started when I repaired a melted button yesterday by putting a brass screw into the derlin button.
I started looking at the inner workings and thought what if I just made it so the brass screw would make direct contact with the top of the battery?
I then realized the original spring rod would not give enough lift to the button. I also realized the original firing pin was hitting the screw and too long.
I knew I needed to bend the original pin just far enough to make a snug firm connection with the screw theads to ensure a good solid connection during the throw which I estimated would only be 1-1.5mm at most. To keep it from shifting I sanded a groove into part of the threads once I knew the throw length was sufficient to just make contact w/ the top of the battery without overthrowing.
Step 2 was to basically take away enough of the original derlin plastic to ensure the the brass screw moved to the battery top unobstructed. Done.
Step 3 was getting enough lift after the fire to ensure it didn't get stuck firing. I needed a spring w/ enough tension....hmmmmm
10 min's later I pulled an extra REO battery spring I had clipped away till I had just the right length to snugly thread over the button. After this I put the cap on which I plan to drill/countersink with a screw later....for now it works it's all I needed to know.
Step 4 reassemble adjust screw as needed then test fire.
Very nice still throw....if you want to keep your button lock don't do this unless you carefully measure it or create a nice groove all away around the screw or do another workaround which shouldn't be too hard to do. I personally don't need the lock but others may. Contact is very solid and the firing is very nice.
I'll try this for a week or so to see how it goes. If I like it I'll get a friend with better tools to do up a more final version.
