Hammer screws

[TARNATION !!!]

I have seen this a few times and admit back when I first started to tinker with Parkers I caused this to happen a couple times. My friend Ron Granger (RIP) explained how to compress and hold the mainspring under tension until the screws were out. The striations on the screw shaft are caused by removing the screw without first compressing and holding main spring tension. Unless this is done, once the screw threads are free the mainspring will push the screw and hold it fast against the frame. You are then stuck with twisting the screw free with pliers and causing those striations. The other surprise if you don’t have the frame wrapped in a shop rag, the mainspring and mainspring plunger come flying out and can be a challenge to find in some obscure nook of your shop floor.

it may be worth mentioning that main springs are properly compressed with a spring vise

as they have been since the days of flintlock and before

These screws are from a hammerless gun. They have coil springs.

Ricks pictured spring vise will not help in any way with them.

Hammer removal is addressed in my photo tutorial on the topic in my albums.

thanks Brian

i read "hammer" and thought side locks


an aside - the Ithaca Flues I cleaned up had a long little post (a 4-40 or there abouts) of a screw holding the top lever coil spring in place, I had to make a jig of sorts to compress the spring to get the screw back in place
