Cylinder troubles
 
1 Attachment(s)
First off, if this was covered in a different thread and I missed it, I apologize. I have an 1851 Navy Colt revolver. The cylinder spins sometimes, other times it doesnt. Im getting a new hand spring and know that a streched body might be a problem since it is brass.The thing that leaves me thinking is that there are small groves worn next to the large ones on the cylinder. Is this a problem or normal wear and tear?


Any help would be greatly appreciated.

I have a 1861 Army Colt 44 cal and some times my cylinder will tighten up on me and all I do is tap the wedge back a tap and it works fine after that .

As advised by TnRebel, slightly tap the barrel wedge back in the (out) direction, the cylinder should loosen up.

Normal drag- no problem unless it wears the shoulder of the locking notches to where they do NOT lock.

Clean the rachet on the rear of the cylinder GOOD (old toothbrush) and make sure they are not wearing (little lite grease is good) and check tip of the hand for wear. Some repros have soft steel on some of the smaller parts.

I've seen it happen to a few officers here in the re-enacting world. As Tn rebel said the quick and easy fix is to tap the wedge back and it should work fine after that.

JLNobes: there are small groves worn next to the large ones on the cylinder.
It appears that the Bolt Head is not retracting below the bolt window and is dragging as it leaves the Cylinder Notch. Off-time Bolt disengagement can be caused by worn or mislocated action screw holes in the frame, and/or in the hammer, bolt, or trigger; ~ worn, altered, or damaged bolt arm or Hammer Cam, or a combination of all the above.

Hey JL:
A closer look at your cylinder shows it is not a normal drag on the bolt head. What I see is the bolt head continues its drag from one cylinder notch to the next notch. That's not good.
This could be caused by "early cylinder rotation". Meaning a long hand (pawl) surface.
The bolt should be adjusted so that as you begin to cock the revolver the Bolt Head will drop just below the Frame Bolt Window "just" prior to the hand (pawl) engaging the Cylinder Ratchet.

A proper adjusted bolt at the half cock position, and the cylinder removed from the frame, will hold the Bolt Head just below the window frame .

Thank you guys for your input, I really appreciate it. How do I adjust the bolt?

Some Brass guns have passed inspection with quick fixes that eventually shows up after time, leaving the owner to find a way to make repairs, or use it for a wall hanger.

Wow ! :eek: That question would call for a course in gunsmithing to answer. But just for starters - - -:D
The Hammer Cam is what begins the process of Bolt Pickup, the Cam rises and arc's rearward as the hammer is being cocked, pushing upward on the left Bolt Arm causing the bolt head to drop out of the cylinder notch. There may be one or several reasons why that's not happening.
