The washer under the serpentine has some room but the inside washer needs to be undersize to clear the inlet in the stock.Grab the dividers and see what we need for size



Then center punch the sheet



and transfer our measurement



Start with a small hole...



Then grab the step bit...



Then cut them out of the sheet



Some work on the 1x30 belt sander and they're round



The outside one is ok but we need to undersize the inner one



Looks good



Clean them up and flatten/deburr



And the fit up

Next we fit everything together,and give the inside a coat with the sharpie

Seeing how much recess I want on the opposite side where it goes through the serpentine,then make a mark with the scribe



Off to the drill press



And that provides a hole for a copper pin to keep everything together

Next we take it over to the weld table,and rig it vertically,and clamp it



Give it some careful welds with the gas shielded Mig



Till it's filled in....



And clean it up roughly with the flap disc



And here's the semi finished dome shape

Now we have to figure out how to make a connection from the sear bar to the serpentine.I coated the round bar with a sharpie,then installed the sear bar,and grabbed the bar size I wanted to use for the sear bar loop.



Marked the length,removed everything,cut the round bar and reinstalled everything

I like what I see done, but even having seen vids of a match lock firing, I'm not sure I know what I'm looking at but a lot of time invested, skill and patience for a project!  Kudos! :thumbs: ::)

This is where it gets tricky with the geometry of operation.I alined the serpentine 90 degrees to the top of the lock plate and kind of guesstimated a start point.I failed to take good pics to show what I was doin to figure all this out.Sorry.Here is where I'm using the bottom of a Vernier caliper to figure out the depth of the cut out.



Here's what I came up with for an angle.I started the cuts with a hacksaw



I left the caliper set and rechecked my cut depth



Cleaned it up with a square file

So now we need to make a connection from the sear bar to the serpentine.I'll start with 1"x1/8" bar-



Then mark out the dimensions of the rasied portion I filed out after covering it with sharpie



Drill it out closely



Then some careful filing



And she fits nice and snug

Gracious...I'm not sure I follow along like some might be able to, but the one thing I'm sure of is that you have a LOT of patience in doing all this...

Congrats on making it this far

Next comes a slot for the sear bar.I drilled one hole and opened it with a file.



And it should line up

Next we'll have to secure the plate to the serpentine.I think we can make a screw work.



First I coated the face with a sharpie,



Then marked it with dividers to find center.





Center punched it



Drilled it



Then tapped it

First I took alook to see where the sear bar fell,and marked it with a silver streak to know where it needs to be bent.



Next I fit the sear bar plate onto the serpentine.Then I took a silver streak pen and marked the radius of travel.





I took a torch and heated the marked spot and bent a 90 in it.



And here it is with the bend fit in place.

Next we can cut the excess off the sear bar



Then I cleaned it up with a file



Here's the full range of operation.Works great
