ATNA No2 antique pistol action help

[laurencen]

picked up a ATNA revolver pistol circa 1895, after several hours got the hammer and trigger figured out and functioning but the mechanics to rotate the cylinder is not correct, I made the push link based on the part broken in the frame, the pin is tight in the link and rotates in the hammer, it will function correct for half dozen cycles but then fails.

Im looking for some info on the assembly of the hammer and push link, from what I see the pin is not shouldered simply a parallel dowel pin,the hole in the push link is 0.002 smaller than the hole thro the hammer so I figured the pin is pressed in the link, however it works its way out of the link. to install this pinyou are working thro the hammer pivot hole so the pin can not be attached permanently into the link, just not enough room, anyone by chance took one apart or have some diagram how the assembly should be?

my next option is make a headed pin, ream the hole in the link, the pin pressed into the hammer and the link pivotion on the pin but trapped by the head on the pin.

this should be a easy task considering the level of equipment in the 1890s but this is presenting issues, I see why they went to removable side plate at a later time.

thanks

I am going to take a wild guess and imagine that you are discussing a single action spur trigger revolver. Maybe an H&R AETNA ?

I have never held one in my hand but these old suicide specials were very simple guns. I'll guess that with the cylinder hand attached to the hammer you can't get the hammer back down into its proper position in the frame, hence having to try to work through the hammer pivot hole in the frame. Which means that obviously there is room within the frame for the hammer and hand to be side by side.

Try this--- remove grips, mainspring, and hammer screw. Now try to maneuver the lower end of the hammer into the open space in the grip frame. That might give you better access.
Where does the hand spring sit ? Some types had the hand spring work on a flat on the hand pivot pin (I am thinking of the Otis Smith guns)
If there is no concern with the orientation of the hand pin (as there is in the above example) then a dollop of JB weld or a spot of solder would hold pin and hand together.
I am interested in your results.
