Charleville is finished. I'm very pleased with the results. I can cock the thing with my little pinky finger. I haven't measured the pull yet, but it is much improved over the factory pull over over 12 pounds. Frizzen tension is right at 3 pounds or just a bit under. Kicks over easy at about 30 degrees. Trigger pull is much improved after stoning of sear and tumbler full and half-cock notches, and cleaning up the gouges in sear arm and trigger, smoothing and radiusing/de-burring trigger edges that were causing the sear arm gouges. Action is very smooth, two nice clicks when cocking. All screws are tight, bridle, sear screw, frizzen spring screw, frizzen screw (thanks to the replacement 1777 screw I cut down to fit), pan screw. Lock plate screws are tight, tang screw tight. I've snapped the lock multiple times with the German agate, always getting great sparks, agate has not come loose, but I used my brass bar (not to worry, I choke up on that bar to tighten, and make a point not to get carried away), not a turn screw to tighten it down, and both sides of the agate stone are very flat. Some re-inactors told me it would come loose very quickly using lead instead of leather, I believe that was using English black flints or French amber flints though. So far so good with that. I'm using the lead Pedersoli supplied. I do have leather if it becomes a problem though with English flints.
Pan is now polished to a mirror finish.
I did make one mistake putting it back together. I probably should have tightened the tang screw a bit, before I put the rear barrel band in place. I did not, and it scratched the barrel on top, probably due to the barrel spring pushing up on the barrel. about 1/4" of light scratches. I can polish them off, but I may not fuss with it too much.
Also, for now I'm holding off on the acru-glass treatment. I may do that later. Maybe even the barrel band wood area if it wears with take down and use. For the time being I did it the old fashioned way, you know, Beeswax and a heat gun! I put a good coating of beeswax on the barrel, heated it to soften and bedded it. That is one reason I got in a hurry putting the barrel bands on. I wanted to seat it while all that beeswax was soft, so excess would ooze out the sides at top.
It did a great job of sealing. I don't plan to clean with water anyway, and I will break the musket down to clean, remove lock and barrel. I'll use WD40 and alcohol. I use brake parts cleaner on the pan and frizzen to de-grease. I plan to use Jojoba oil for swabbing the bore, and my beeswax/Crisco mix for lube goop softner.
I learned a lot working on this musket. I did treat the lock parts with Militec-1, that stuff is great. Good for engines and transmissions too. Internals are greased with old school Mobil 1 synthetic grease. It is a very light grease and slick as snot!
I'm ready to make something go bang now! If the screws don't hold up from take downs I may order more and case harden them using Brownells surface hardener goop. I have the right screw drivers for all screws though, and that will help keep them from getting buggered up too. I found Jim Chambers excellent tool worked great for the cock to tumbler screw. It was wide enough, and thick enough to fit the screw like a glove.
My vent hole lines up like the rising sun with the pan flat surface, agate stone points to middle of the pan at half cock.
What I have learned for sure, is anyone who buys a factory piece should tune that lock before ever even dry firing the piece. Clean, de-burr, polish, decrease spring tension if needed and lube. On the 1766 Charleville I highly recommend replacing the frizzen screw with the 1777 screw from Dixie. That way you can tighten it all the way into the shank, and it won't come loose, you'll have to cut off about 1/4" from the threads so it won't stick out into the mortise. Some of the other screws may need work if you want them to seat tight without binding.
The cam on my frizzen needed some work, it was too squared off, and needed rounded to kick over easier, and the flat was too wide, all of that was also causing gouging the frizzen spring. I cheated and used Dave Person's excellent tutorial on his Brown Bess project to reshape the cam, without making a mess of it.
The Pedersoli lock had great geometry as Dave Person commented about it. The springs were heavy but shaped well. It was very rough, and those MIM parts needed stoning and polishing, the tumbler was the worst of all, especially that boss that was supposed to reduce friction by lessening the contact surface with the lock plate. It was rough as cob, with what looked like welding slag on that boss. It had scratched the piss out of the lock plate in just the few times it had been cocked at the factory, and by me. Main spring cam arm on it was rough as cob too, with casting ridges on both sides that had already cut grooves in the main spring end that made contact with it. All was stoned with Hard Arkansas stone and polished to mirror finish. Pan to frizzen gap was .007" from the factory. I've got it touching now.
Pedersoli used a light grease to seal the lock pan and barrel. I didn't like that at all. The grease was too close to the vent! I figured it would heat up and wick its way up via capillary action, and into the pan. Petroleum products and black powder are a bad mix. I used beeswax to seal that area.
I ordered the 8 book set of Kit Ravenshear's books from Dixie. They are on the way.
I am looking forward to building that The Rifle Shoppe French Charleville 1763 pistol kit at some point in the future. For now, I am getting kitted up to dress the part of a militiaman at SAR.
I have the rasps, files, and wood chisels needed to work on the stock of the 1763 pistol kit. Only thing I don't have are some of those round scrappers Brownells sells. I will need advice when it comes to finishing the wood. That part I have zero experience at.
When I get around to it, I will post some pictures of my completed 1766 musket for the members to see. I took my time with this project, worked on it when I was in the mood. I really enjoyed it, and it was well worth the effort. No lock jump when firing now. I can hold on target with no movement when firing now.
I posted a picture of my horn and bag too, I have since tied the stopper to the sling, so I won't lose it. Used dark green hemp string. I took Black Hand's, and others advice and got the smallest bag I could get from The Leatherman. It is 8" X 9" Trapper model.
Thanks for all the help and advice, and encouragement members gave on this lock tune. Especially Flinter Nick and Dave Person!

Very nice, I got tried just reading of all the work that you have done. NOW, will you please go out and dirty the dang think up and let us know if you miss or hit the target.
Sounds like a plan. Tomorrow is my 66st B-Day. It also happens to be the Buckeye Firearms association annual “Gun Bash.” It has become a family event for us so we are all looking forward to it. Cam Edwards of NRA Radio is the Keynote Speaker. Always a good meal and good fun!
Betty and her older sister leave to visit their oldest sister in Florida next Friday. I’m staying here with the Golden Retriever, Abby.
I hope to get out to the range, or shoot off the back deck next week, or while Betty is in gone for 8 days.
I will post some more picks of my dirty musket, and let you know if I could hit anything with it!
I have the stuff to make up paper cartridges, but may just shoot bare balls, with tow.
I’m really looking forward to making smoke!

Happy Birthday my friend, and good shooting.
 
You got that lock looking good PluggedNickel. I'm sure it will please you when the shooting starts. Personally I would ditch those agate flints and get some good black english flints from Track of the Wolf, or/and some blond french flints, and learn to knap your flints. I have never had a cut agate flint that sparked over 1 or 2 shots, maybe yours are better.
Just out of curiosity, how did you determine that 3 pounds was the proper weight at which the frizzen opened? The only time I've seen that value placed on opening the frizzen was in a conversation on another forum concerning tuning that "jump" out of the lock. 3 pounds is my target weight for the frizzen opening when I tune a lock. A little less when tuning for set triggers. And I related that figure in my posts. Coincidence I guess.
Many of the things you did is what I do to get my lock "In Balance", yours is probably several steps beyond what most shooters will do to a Charleville.
You did it different than I do. I polish what I know needs polishing at final assembly of the lock. Then as the need arises I will tune out problems as they arise, all this is done over a period of time. I think I'm too impatient to do it your way.
 
These pedersoli locks certainly can be good locks if tuned correctly and you have done that. IMO when the issues are corrected it bumps these into a finer category and they become much more enjoyable!

My only advice would be to ditch that cut flint a get a 1" english. Also try squashing a lead ball and using that in the cock jaws to hold the flint, which it seems you have already done.

Thanks to all.
Is it faster? We are talking nano seconds of time huh? I’d say yes due in large part from tumbler boss not grinding into lock plate now, and smoothed out tumbler arm not gouging main spring. Ignition should be improved by better sparks, and polished pan. It does Spark better, cocks easier, doesn’t jump when snapping the lock. I found the best way to test for improvement in this regard, is to snap the lock held in hand. From the factory, you really had to hang on to it.

I used the theory that the frizzen tension should be about 1/3 of main spring to come up with 3 pounds. I came to this from reading what others have used to balance the lock, Darkhorse your posts could have been one of them for sure. Adjusting frizzen cam shape, polishing frizzen spring, and cam, and reducing spring weight,all reduced flint abuse with English flints, and stopped cutting ridge into frizzen.

I do have TOTW English black flints for re-inacting. The agate flint is working fine though for plinking. It seems to be easier on the frizzen, perhaps due to such an even edge. And, the agate is the perfect length for this lock. I do plan to make a Knapping tool, and learn to do that as well. HOPEFULLY that is, it seems to be a lost art for most to master.
As delivered, the lock would chip the flint upon snapping, the factory flint was way short though, and lumpy, it looked like it was a hunchback on top, still the lead held it firmly in place.

I can tell you the hardest part was polishing that pan. It was very hard, and I didn’t anneal it, and re-harden, and temper. It was slow going using from 220 grit wet/dry to 3,000 grit on a dowel rod, then final polish with jewelers rouge and wool felt wheels on the Dremel tool.
I took breaks from that tedious job, worked on other things, and went back to work on it, when in the mood. If I hadn’t needed the earlier musket for SAR re-inactment, I would have went with the 1777. It has all three barrel bands having springs, the rear band is friction fit on the 1766, but most important is the much easier to polish and easily removed brass pan.

I am glad I got this musket during the cold winter moths. It allowed me to not get impatient and take my time on this lock tune. If the weather had been nice, I would have wanted to get making some smoke sooner!

Pedersoli should take a look at Dave Person’s frizzen cam geometry fix. It seems to be a common problem with both BB, and Charleville, and probably all military muskets from them.

My wife Betty took this picture of me with our daughter and son-in-law at the gun bash yesterday evening.

George, it is George right? I looked up the post I referred to, it was posted in March 2019 and titled "Flint Lock Tuning". But the main question was how to determine if a lock was in "Balance" and how to fix it if it wasn't.
Smartdog was the one who applied the 1/3 value on the opening of the frizzen. I personally never thought about it that way, due to tuning several locks I found that 3 pounds measured with a trigger pull gauge worked well for me. Actually my target weight is no more than 3 pounds. Like Smartdog I also tune for numerous shots, not just a few, I want mine to be consistent for as many shots as I want to take in a days shooting.
I think every flinter worth his salt should learn all he can about how the lock works and simple repairs. But I find it hard to really open up about my methods because my mentor in the Flintlock was against it. He got the shakes when someone talked about stoning in the lock or reducing spring tension. Simply because this can easily make a safe lock unsafe. Others feel the same way evidenced by the lack of technical posts regarding issues like this.
I have seen more posts this year about this subject than in the last 20 years. Maybe people are questioning why certain shooters always seem to edge out his competitors.
 
Yes, it is George. That makes sense to me, and would explain why so many are averse to even discussing lock tuning. I've been tuning SAA revolvers and lever action rifles for SASS shooting for years, so perhaps I'm not as spooked as some would be about polishing and tuning a flintlock. My frizzen ended up just under 3 pounds and I am very pleased with that.
I may make some paper cartridges to shoot next. I've got the stuff to make them with now.
I'm sure I read your article on Flintlock tuning. I've read everything I can find on here about flintlock, shooting, tuning, maintaining. I also have purchased several books about the same topics, and a couple on period correct militia kit.
 
Howdy, I own a model 1768 Charleville. I believe it was manufactured in India or Pakistan. I was experiencing many of the same problem as PluggedNickel. Actually, my lock froze and stayed at half cock. I am too naive to begin to attempt the repairs outlined here. so I removed the lock and mailed it to some one who could tune it. Hopefully, It is coming back this week. I am interested though, I have seen the term "stoning" in several other posts and I am not familiar with this. Can you explain?
