...I made a replacement for my AK-63D hammer spring.<br />I got three wires of the appropriate diameter twisted them together in a braid then bent the spring in the proper shape.<br />4th time was the charm, not too long, not too short, Not Bent in the wrong spot, not too wide that it interfered with the trigger.<br />It did have to be anneal it in the oven but after that it works great except for the fact that it is much stronger than the original.<br />The hammer is held up with such force that if you lightly return the bolt after injecting around it will act as a bolt hold open and a light tap on the handle after the magazine is inserted will send the bolt home.<br />If the trigger is held down while the bolt Cycles or if when you cycle it manually and you release it and let it slide with its own force it will not even hint at holding the bolt open.<br />The trigger is a little bit more firm but the AK trigger system is heavy and gritty anyways.<br /><br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8515829.post-77840908541165919142015-05-21T13:54:41.586-07:002015-05-21T13:54:41.586-07:00Based on your blog post, I just did this.

Use it as my turkey gun so I wanted something more rifle like. Polished the hammer & sear engagement surfaces and that dropped the pull about a pound and a quarter (and smoothed it out). Wanted more, so I created a new trigger spring. Original spring was two turns of 0.039" wire. Bought some 0.032" wire at Ace. Wound it by hand (only two turns on my orig. spring so I didn't use the drill method). Created the exact same spring with only two turns in it, just with smaller diameter wire. Popped it in and it decreased the pull from 5 lb 1 oz, down to 3 lb 9 oz! In this case, an 18% decrease in wire diameter yielded a 30% decrease in trigger pullAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8515829.post-32340695936665350452012-07-01T17:53:27.902-07:002012-07-01T17:53:27.902-07:00Great post you have here.

I liked it. A LOT. Until the extractor broke and flew Deity knows where along with it's spring and plunger. My local (within walking distance) gunsmith wanted an extortionate amount of geld to make, procure replacement parts, around $20 as I remember. That kind of money would have got me and my romantic interest at the time a nice dinner, a movie and a tank of gas to get us back to her apartment so...... <br /><br />I got hold of a piece of air hardenting drill rod, sawed and filed on it for a couple of hours, until it functioned as an extractor, made a plunger out of a piece of 12D bright common nail chucked in a power drill and turned with a file. Then tried half a dozen small springs starting with one from a ball point pen. I finally liberated a broken guitar string from a buddy and wound several springs on sundry mandrels until I got the OD coil I needed. I tried varying lengths until I chanced upon one that functioned. Drove out into the tules to test it. Everything worked fine, and continued to do so for at least five years. I traded or sold that pistol for something vital at the time and haven't heard about it since. Lessee....25 from 67 is what?.....42? That's 42 years, what's the expected serviced life of a cheap .22 auto pistol anyway? I've made hundreds and hundreds, dozens maybe, of springs from music wire. For years I'd beg broken wire guitar and piano strings from Stan Boreson's Music in Faraway, Exotic Ballard in NW Seattle. He closed his store about fifteen years ago, but I still have a shoebox full of sundry sizes of music wire, so useful and so cheap.<br /><br />Gerry N.Gerry N.noreply@blogger.comtag:blogger.com,1999:blog-8515829.post-25340090786329668992012-06-24T10:34:51.913-07:002012-06-24T10:34:51.913-07:00Question, and I ask this out of a small knowledge ...Question, and I ask this out of a small knowledge of tempering/heat treating: is the spring you made tempered properly to act as a spring? That is to say, when it is compressed, does it return to true reliably? Is it hard enough to flex without taking a "set?" Is it still soft enough to prevent snapping from brittleness?<br /><br />I'm just curious, not criticising.Bobhttps://www.blogger.com/profile/11402651457453813639noreply@blogger.com
