Another thought, mainsprings have been known to take the bottom of the stock out when they break. It depends on the configuration and strength of the spring and the thickness of the stock. That's a stress riser, a potential break; it needs to be dealt with. It doesn't matter what the origin of the crack, cut or whatever its called is it is a big time problem.

JB weld would just be cosmetic and not provide any strength. That’s something a Charlatan would do to camouflage a defect when selling a gun.
While not a full strength repair the J B weld would prevent the spring from flexing in the area of the cut/crack and give some support. Definately not a permanent fix but it could extend the life of the spring.

Well - Final control still seems to be a serious problem for our Italian friends !

My shooting buddy war one of the first to purchase the then new Pedersoli Kuchenreuter Pistol , SerNo 10 .

After the first string , the sear nose broke . Having got a replacement ( after a loooong time ) , the spring broke ... Also after a loooong time , he got a new spring - after the third shot , the stock broke ...

The main issue from the third or fourth shot on was , that it became nearly impossible to load the next shot without throughout cleaning ...

Completely confused , my good friend considered this entire pistol as complete chunk , took it apart , kept the barrel and threw away all the remainig parts as far as he could . !

Now , after several years , he gifted me the barrel .

The scope shows the main problem :



After a good polish with finest steel wool and some chrome polish , this left hand drill barrel shouldn't be too bad , therefore I tried my hands to turn out something functional .

After lapping the inner surface of the barrel , I decided to fill the cutout for the underlug , adding a new sight . and make a completely new and different pistol .

Some of You already know , that I'm a complete fan of the Ruggles style ( only four moving parts ! ) pistols but I'm also aware of the superb handling qualities of the great Billinghurst works of art .

Therefore I started to make a blend from the the best of both :

Barrel : Remake of a Kuchenreuther
Lockwork : Remake of the original Ruggles - Patent - Underhammer
Stock : ( With a little phantasy ) : Billinghurst

Well - in the end , it became a shooter , even if difficult to load after some shots without wiping .

Te Pedersoli barrel is proofed in .44 , but with bullet .424 , patch in o,13mm maco cotton wool patch and 20 grs Wano ( Schuetzen ) PP , it turns out to be a really good shooter ...

Agree with your statement about not being a permanent fix, but do not see JB weld extending the life of the spring. When I was in the tool room and then over it it, the use or suggestion of using JB Weld in any kind of structural or stress application was a running joke. Why not just grind out the so called ‘nick’ and and eliminate it from being a potential cause of spring failure? Seems silly to attempt the use of epoxy/plastic to ‘repair’ a steel spring. Or maybe it’s just me and folks love a ‘possible’ repair of a spring with epoxy/plastic.

Hello, you have to start knowing the code of the main spring, looking at the parts' diagram you can find in Pedersoli's website where the gun is featured, Chaleville's main spring has the code 0800003703, DGW may have the parts in stock, another representative carrying parts is V.T.I www.vtigunparts.com, using the same part's code and finally Pedersoli has an online shop where it is possible to purchase parts and accessories, delivery time 2 or 3 days from the order https://shop.davide-pedersoli.com/en/
Top Notch MGA you are awesome I went to the Pedersoli website and downloaded the 1763 (1766) illustrated parts breakdown same you referenced for me. I’ll be getting the part and maybe some other springs just to have! I ordered some mini carbide grinders the polishing rubber sleeves Gus recommended and some polish. Should all be here so I can hollow out debur and polish the existing main spring in perfection. I should be at the range by 10. I’ll send some pictures for the group critique! LOL.
Thanks everyone one for the help. I’m going to try VTI first i owe him some money for a hammer and bolt for my Pietta 1858 Sheriffs Model he sent me. Kill to birds with one ball LOL. Joy!
Thanks

Thanks Gus!
Pedersoli parts 1 800 450 -1852
I just sent an email to Pedersoli asking for the PN of the spring. I called that 800 number I found on a similar thread they need a PN to insure fit. Can’t argue with that. Once the order is placed takes 60 to 90 days LoL. Things are really upside down nowadays.
I will do that need to order up some cratex. I’m hoping it’s just cosmetic I never noticed it before though it looks like it’s been there all along.
FWIW Pedersoli once also quoted me 60-90 days (60’ish with luck) and I got it in about 25 days.

I believe the word is imminent, which means "about to happen". Eminent is an adjective used when referring to someone held in high regard in a sphere of influence or profession.
Roger! You are correct as the definition supports. I read at a 5th grade reading level thanks for improving my vocabulary! the definition is spot on We used to call my Director My Eminence! He looked the part of royalty just needed a fine robe and crown. Thanks 🙏

Only problem with ordering today with Pedersoli is I have to get hot and place the order because the woman explained they go on vacation soon and shut the factory down for a month. So I have time but not much I’ll be making all my calls Friday. It’s an off Friday this week for me. Let me ask upon receipt was the spring in a drop in highly polished state obviously your s could be different. They put a lot of effort in polishing that main spring I’m sure it is not cheap! Later off to work!

I was just going to reinstall the lock on my Pendersoli Charleville and noticed a flaw in the main spring right at a point I would think is a high stress area. I think it’s a flaw; regardless I think it may break. I’m going to order a new one which I hope someone has in stock. I bought it from Dixie so I’ll start there. Anyway I’m going to try to polish it out until I can no longer see the crack in the spring. I don’t think it’s a stress crack I would think it would have already cracked being these spring are so hard. It’s obviously needs attention?
Looks like a nick. Looks like you could file it out. Looks like there is room to do that.

The spring would have tension there, but no flex.

Having had a lot of experience with Pedersoli and their main springs over the past three decades ...,

YES order a replacement part, BUT because it's good to have a spare mainspring, not because that one's about to self-destruct. ;) From VTI gun parts on the drawing the part is "15" and the code number is 0800003703 (might be Pedersoli's number or might be VTI's number) VTI Gun Parts Charleville Versions : Pedersoli

I'd also just shoot it for now :). Twenty-five years ago Pedersoli was shipping NEW Bess with obviously cracked mainsprings..., when folks ordered replacements, they arrived with a crack in the same place. They worked fine.

As others have already stated this is a stress riser and WILL fail in the future. I would order a new spring but I would also file/grind out the "nick/crack" then blend & polish the area with very fine abrasive paper or use the Craytex abrasive points mentioned above - just be sure you remove all of the anomaly and blend it in smoothly. :thumb:

... try using a round carbide file or small rotary stone in a Dremel tool to get rid of the nick or crack and then polish with cratex abrasive "points" to get it real smooth.

All:

See this post here, by the late Zonie, see reply #4 ... and bookmark it or place it on 'Watch' in case you ever need to reduce the power of any leaf spring:

'Thinning' a mainspring?

All grinding or polishing should be in the plane ALONG the length of the spring leaf ... not across the shorter widths.

Thanks! I did both polished the crack and ordered two replacements. To be honest I forgot who I ordered them from though I believe VTI. Yes the new springs are not perfect either.
Cheers
