Damn snow knocked out the power to my shop for three days....But I did have power at my home, so I brought her home to tune up the triggers. Take note of the springs. The coil springs I was using were just a touch too wide for the frame opening, and rubbed when removing the trigger group. I replaced them with Belleville washers. They are washers that are cupped. The cool thing about them is the amount of power they have in such a small space. These washers are significantly stronger than the coil springs. Plus, they allow fine tuning of the resistance by stacking them in parallel ( facing the same way). Not to mention, with 36 on each pushrod, there is a lot of redundancy so failure will never be an issue. They look cool too. Only drawback is they are expensive, $1 each.

Here is the trigger group partially inserted into the frame.
