This looked easier to do than it actually was. I'm still an amateur at best but it came out OK.
I wanted to build the side plate from sheet brass for a few reasons. First, I wanted the side plate to align and be sized the same as the lock plate, and I wanted the side plate brass around the bolt heads to be nice and even, and I wanted recessed bolt heads in the plate.
I ended up with all that, and got the front bolt placed properly right in the web!! Miracles do happen!!
The bolts are my "working bolts" not the finished ones. I have a more edge beveling to finish along with evening out the brass around the front bolt hole, and making the front nose a bit skinnier. Once I have that to my liking I'll proceed with inletting the side plate.
These things seem to take longer than I initially think they will....but when they work out it's all worth it.
