- Hacksaw with twin saws
- Grinder (If your impatient)
- Common Sense (Don't kill yourself)
- Copper Sheet
Basically you have to simply use common sense and use the above tools to create the shape out in the picture below. then drill a hole for the nail and with your copper simply bend it around the nail until tight. Position the cuts in the copper to where your spring in the trigger is.
You will need to slightly dremel your shell to fit the trigger in, take this slowly or you will take to much off. The piece the rail of the trigger sits in may also need some light dremel work.
Finished product, this was one of the first ones, as we make more they continue to get better and more accurate.
