I am making the lock based on pictures of Samuel Morrison rifles. All his locks seem to be different and hand made. All of the works are on the outside of the plate, except the frizzen spring.

I still need to polish and case harden the parts.

I popped a dozen or so caps with the lock. It seems to be fast and reliable.

Liking your build a lot!  Perhaps I missed the barrel specifics:  maker, caliber, length and width across flats?

buy a set of premade paul Griffith style  with ball front sight from robin warner. that is the hot set up over 75% of chunk shooters u8se them and almost all the top shooter . love  your lock. leave losts of wood on top of comb till you get your sights on and shoot it. no fun after gun is finished realizing to combs to short. you did great going with nice wide gentle curved butt plate.

Don,
Can't post but the sight is nothing more than a post with a bead on top. If no one posts later, I'll forward a pic to you this evening.

Thanks guys. I believe I understand what is being referred to.
I have a set of inserts for a front sight which includes one that sounds a lot like what you're describing.
I looked up "Globe Front Sight"...couldn't post a picture here.
Is this sort of front sight setup permitted..????
Thanks.

If you want to see what Pauls rear sight looks like go to over the log page 3 and look for diamond sight go down
through the post and you will find a picture of Pauls sight.

Don,
Paul, and now Robin, also made a tall sight with a round bottomed straight notch. Both work well with the post and bead front,depends on what you like.

Moving right along and looking positively svelte.  Have to get out the panoramic lens to take a picture of the whole thing with the big and long barrel.  Have you decided on the design of the forend rest yet?

Took the rifle to the range today and shot off a couple dozen rounds. I got the cheek piece filed to fit me.
The sights were off a good bit, but I need to put the barrel in the vise to move them.
I discovered that the mainspring on the lock is too weak. Too many caps didn't go off the first strike. I'll make a stronger one.

I tried several different patch materials, and found a lighter weight denim that worked well. Used Balistrol and water mix for lube. Cleaned between shots with the same mix. I think my denim was too worn out to make good patching material. I noticed some balls went down easier than others. I'll measure, and buy some new. The patches looked good after firing.

After settling on a patch material, and charge, (120 gr. 2F) I fired a 10 shot group at 55 yards off a chunk. I think most of the vertical spread was due to different patch thickness, and my inability to see the target clearly. It was hard to tell when the front sight blade was even with the bottom of the black square. Maybe a ball sight system and round spotter would work better for me.
There was very little recoil from the 21#, 48 cal. rifle. The group measures 1.55" center to center, and my best guess would be about a 7" string.
I'm happy with the results so far, and feel I can finish the rifle now.

Here are some pictures of the finished rifle. Weight came out at 20#. Some pictures are mirror images. The rifle is right hand.

Oka, did you get your mainspring sorted?

very fine gun  dont shoot next to krumme or disboro they love side locks.they would drool on it to much. as for your firing problem make sure the hammer face is hitting the cap square..that is not a uncommon problem .had to fix 2 of my own guns .next don't try and shoot the front sight dead on the black. leave a little white will help on the stringing. the bevel brothers and paul Griffith put a 1 1/2 wide - as long as blacksquare-   strip of  fluorescent orange under the black they shot when orange could not be seen
hope any of these old fart tips help you out . do love the neat gun you made .keep up the great work

Very nice build! thanks for shearing. I'm a underhammer guy myself and get alot of questions at the shoots I go to. Sometimes its really fun to show up with something different. 
I also build my own muzzleloaders. I have built two. One for my daughter to shoot in 4-H and one for myself for round ball competitions. 
Next build is a slug gun in 45 cal .458 Dia. 
wish me luck lol.
