Flint gets stuck on hammer face.

[Nemo Vir]

Need help, sometimes the cock falls and I gets sparks. Other time the flint gets stuck half way on the hammer face.
Do I need new spring?

Pull the lock 1st /clean /lube reinstall not over tightening lock bolt ,make sure moving parts are not making contact with wood anywhere . You did not mention lock maker (quality or other ) but imports could be using a cheaper part than a name maker (custom supplier) ,but yup you might need another spring if available/or lock /Ed

More info needed. What kind of lock? Did it use to work and just start doing this? Does the frizzen open easily if you move it by hand?

 

[French Colonial]

Not enough information.

Pictures, and everything Trot asked.

 

[Nemo Vir]

Sorry, it is a Chambers English Gentleman Sporting rifle. It was made for me by a gentleman recommended by them. I forgot the name. It seems to start doing these randomly even after being clean and with no powder in the pan.

Could also be the flint is too short or angled downward and striking very low on the frizzen. Have you tried a couple different flints?

 

[Trot]

Also try the lock out of the rifle, it may be binding on the stock.

 

[EC121]

Are you oiling or greasing the frizzen spring contact area and screw? Does the frizzen snap open when slowly pushed open by hand?

Flint too long.

 

[flintsteel]

I agree the first place I’d look is the flint too long? If it’s hitting more than 2/3 up frizzen it needs shortening or changing the bevel by turning the flint over.

If nothing else works call Jim Chambers. Great guy and one way or another he will put the lock in shape.

I have one that does this sometimes. I can knap the flint in situ and it will go back to working.

Definitely make sure your flints are the correct size. Better to be a bit smaller than a bit larger.

Give us a picture of the whole lock at half cock with the frizzen down, then at full cock.
