Layout Question

[Scota4570]

I am working on a 1/2 stock Leman parts set.   I do not want a cap gun.  The barrel is 15/16. My layout drawing gives me concern. The drawing is accurate to a close tolerance.  I really waned to use one of Jim's new CNC locks.  I think it is too small.  The lower portion of the stock under the lock seems like it would come out too thick.  To my eye that would look goofy.
The "Late English" looks better.  What are measurement guide lines on the amount of wood in the area indicated in the drawing.

Builders who have primarily made rifles from the 1760-1810 era try to follow certain “rules” regarding lock panels. Rule #1 is keep them as narrow as possible. Rule #2 is make the top edge of the sideplate side lock panel line up with the top edge of the side barrel flat. Of course there are plenty of regional exceptions.

Those basic rules often but not always goes out the window on later guns, and Lemans are later, often post 1840. Many original Southern Mountain rifles have very wide lock panels.

Study some Lemans. Here is a link to what may be a Leman in original flintlock.

I don't know anything about Lemans, but from what I can tell from your drawing, I would say right off that you have way too much wood left underneath the ramrod.

I would just go with what looks right to your eye and go from there. I've always used a masonite pattern taken from an original for the profile. If the bottom side of the wrist doesn't look right, change it! Any changes need to be gradual so they don't stand out. Make sure to leave enough wood for the trigger and trigger guard. If you look through some books that show multiple guns from the same maker, you'll see that they all vary some. The overall profile is there even though the actual dimensions vary. Trust your judgement!

If your talking the Kibler late English lock it shouldn't be any different than his stock. Doesn't it have a 15/16 breech?

I have this precarve.  It needs a lock that is taller. 

I want an excuse to buy Jim's CNC lock.  Other suggestion on an original gunsmith who used locks like the new Kibler CNC?  Yes Jim's SMR but I want a shorter barrel.  I have already assembled a couple of SMRs.

The length of the barrel has nothing to do with the height of the stock at the breech. A pistol has a short barrel and would be the same height with a 15/16 barrel.If you want a kibler lock just use it.
4.75 X .920 behind the fence according to Kiblers site. That small amount would not stop me from using one.

I lay out the blueprint with the parts determining the architecture.  I’m pretty sure the Leman shop used a variety of locks and made it work despite variations in lock dimensions.
