I am in the process of talking myself into building one of Stith's Hawken Squirrel rifles. Does the pre-inlet stock (90%) make this match up on the snail any less difficult?
I actually prefer the lock not being pre-inlet, it just leaves you extra room to get things right.
With a pre-inlet lock you are now working with a couple more variables that all have to come together at the exact same time.
I will try and explain, but it's convoluted.
(if you have the lock pre-inlet 90-95%)
As you are inletting the tang/plug/barrel, roughly try the lock in it's inlet "often".
Yes it's sitting on top quite a bit, but you will see if the notch is lined up close enough to where your breech is that the lock won't have gaps around the inlet.
Even though the lock is "mostly inlet" you still have a little wiggle room to get things lined up properly.
That might sound confusing but that is part of why they say not to try this as a first project.
IF you inlet the barrel/plug/tang too far back OR forward(and I mean 1/32" is too far) you will have gaps somewhere because you only have so much wiggle room on a pre-inlet lock - the cutout in the lock must "hug" that snail.
Once the barrel has reached it's final position, you can go at the lock.
The barrel/tang was tricky because of the beavertail tang - if you start inletting it and realize you are too far forward or too far back and try and move it, you will have gaps around the tang.
(what this boils down to, you are trying to figure where the tang needs to be with it sitting not inletted yet, and have the breech snail, which is not bottomed out in the barrel channel, lined up with the cut in the bolster, which is sitting proud of the inlet, BEFORE you start inletting the tang. And if you get any of that wrong, you have "gaps"- and then you just pray that there is enough wiggle room in your lock inlet incase you were out a couple mils and the snail is now binding or not precisely lined up with the cutout)
So now with the barrel in ”“ good or bad, it’s time to fit the lock.
The best way that I have found to do it is - strip most of the guts out of the lock (mainspring, sear spring and sear etc) just leave the tumbler in place and the hammer fastened - that way you can see "where the hammer will fall" operating it by hand.
So now that you have the lock with the floppy hammer you (finish the)inlet in the bolster area (the part that snugs up against the barrel) until the lock plate bottoms out (sitting proud) in the unfinished inlet - so the bolster won't quite be touching the barrel but will be close, but the bolster will totally be in the inlet ”“ just the lock plate will be “hung up”.
Then snug the snail notch cut in the lock (if you have a pre-cut) as tight to the snail breech as you can.
If you haven't already installed a nipple in the breech do it now - you need to rotate the entire lock at this point to get the hammer to hit the nipple "flat" - while you can modify/bend the hammer a bit, as a first step you want to get it as close as possible without rotating the lock into a position that is noticeably cock-eyed.
Since the lock is not all the way inlet, the hammer will likely not (cover) the nipple, it will be out too far, but you will see the "geometry".
Once you have it where you want it, and the notch in the bolster is still tight to the snail (in fact it is acceptable to be kinda lifting the barrel up a hair - the cut out can be "touched up" with a file for a final perfect fit - most are just a touch "too small" on purpose to allow final fitting - in a pinch you can also file the snail itself as long as you don't go nuts - I'm talking like 1/64th-1/128th of an inch), I trace around the outside of the lock (while holding it firmly in place) with a pencil.
That tracing is now the "outside" of your final lock inlet.
Then just finish inletting slowing, keep retrying the fit.
It helps if you file a draft around the lockplate -just taper it a hair so that it kinda wedges into your inlet (standard practice with any lock, inlay, sideplate etc).
(the above is probably confusing - I have re-read/re-worded it a couple times and I'm confused myself :rotf: - which is probably where the second part of the recommendation for Hawken builders is the suggestion of a mentor - somethings are just super difficult to try and explain)
