I took apart the Lock and I'm beginning to take wood down around it for it's final fit. I still have to drill and tap the plate screw to the other side but I want to get the trigger assembly placed correctly first.
A close up shows the trigger blade in the fire position where it will trip the sear. But things aren't working as expected yet. So I still have some work to do.
Here's a bottom view of the trigger assembly. I'm not sure if I have to inlet it deeper to adjust the trigger or not. More research is needed.
