I think hes got a good point there.

Handw**king the bolt is crappy and uneven.


It goes without saying that even in the white (no finish yet), this build looks stunning.

No, I haven't reached any conclusions yet with the recoil. I did purchase a large diameter spring and threw it in there. Interestingly, it is yielding the same results - All but the last round seem to feed OK.

I have a friend from Tuscon visiting this weekend and we're driving to Salem Oregon to visit a military vehicle function that should be very interesting. And then I have to travel to Maine the week after for a week or more. Then, between work picking up and summer family fun... Well - I hope to be back on this project soon, but there is going to be some series of interruptions in the coming weeks.

The vehicle show in Salem will be a welcome side note to me, and may lead-in to my teasing about "prior projects" I mentioned earlier in my postings.

Anyway, I'll report some more progress soon.

Stunning is a bit mild, don't ya think? Some of the prettiest work I've seen anywhere on a firearms build. The boy's got talent.

I had a little time this weekend to work on my project. I fashioned an ejector from a 5/16" drill shank. It's inserted in the style of the original with a roll pin to retain it...







I also had to tweak the Tapco AK hammer to work on my build by adding some meat to the business surface. The hammer was striking the face of the bolt a little low leaving the face of the hammer resting below the firing pin and at a notable angle. This was good, because I also need the extra "meat" to ensure that the disconector would engage. The hammer now strikes squarely and the disconector engages well.





I also spent some time polishing some of the trigger and FCG parts. Next, I need to fashion the firing pin arrangement and finalize the recoil spring assembly.

I'm curious if all the polishing the hammer and FCG etc smoothed the trigger out at all?

I had a WASR that used to feel like the trigger was slapping back into position and it would jackhammer my finger. Ever since then I haven't associated AK triggers with being smooth and/or crisp.

The disconector design on some of the AK trigger designs is too long in the back. When the hammer cams the disconnector back during cycling the disconnector bottoms out against the trigger. The hammer then forces the whole trigger assembly to pivot forward to allow enough disconnector travel for the hammer to snap under it. That stings your finger. The cure is to grind a bit off the rear tail of the disconnector to allow more travel.

X2 on the trigger slap causes. You just need to file down the bottom of the disconnector in the area where the spring comes out. Make sure you are getting good disconnector engagement with the hammer though, else you will trade-in trigger slap for hammer-follow.

I can't detect any gross interference on my build yet that would produce trigger-slap, but until I fire live rounds...?? I think the long transfer bar on my build my dampen any slap that may be there. I have a Romanian 1964 vintage AK that had terrible slap when I first built it. I didn't understand at the the time what was causing it, so I replaced the Arsenal FCG with a Tapco one and it seemed better, but there is still a little there. You just reminded me that I need to work on that one.

Before working on the recoil spring assembly, decided to work on the firing pin. The AK firing pin was about 1/2" too short, so after wondering what to do about that, I decided to make the firing pin very short and use a plunger to transmit the hammer blow to the firing pin. (Or, a two-piece firing pin, if you will...)

Material was added by weld/grind to the the back-end of the firing pin to shoulder the firing pin spring. Similarly, material was added to the plunger with weld/grind technique, and these two high mass ends contact each other.











The plunger is made from the shaft of an old torx driver tool. Pretty hard high carbon rod. I'll need to make another one, as I ran out of mig gas and the build-up I put on the end looks like Swiss cheese.

Next, I'll work on the recoil spring, then fix a crack I made (separated weld) in the mag well after beating a pin in and out several times while fitting the extractor. Then, I'll work on the sights and work some more on the feed ramp. I can feel how close the time is coming for me to go out and test-fire. Should be fun.

I should have listened to you guys... The telescopic recoil assembly proved to be too problematic. You lose a lot of length with a closed-bolt and hammer arrangement compared to the original closed bolt / slam-fire arrangement.

I added a tube to the bolt to serve as clearance for the hammer. I am currently looking at using a tube spacer and spring. Seems to work fine.

Dry, it did feel like it had random binding. Light oiling helped, but soon the binding would return. I rubbed on some light grease and it feels real good and smooth.

Question: Is there a general rule of thumb when it comes to lubricating a tube-based weapon? Am I good to run light grease?

I'm about ready to test-fire, but we're in a drought and I don't think I can just drive out into the boonies until it rains again

After a long pause, I had time this weekend to work on my project. I had a bunch of small things to do, but "small" is a relative term. These things were little chores, but the added detail is really spruced her up.

Here's a pic of what it looks like right now:



I fabbed-up the front sling loop and settled on a way to hold it in place using a couple of pins:





I completed the front sight and fabbed a rear sight with windage adjustment:





Here's; a couple of pics that show the over-all with the added details:





Well, it's pretty much ready to take out and test-shoot. I don't know how long I'll need to wait until the wild fire risk passes, but a few more rains and I should be be good to go. Between now and then, I'll massage the scratches and dings. After test-shooting, and after any necessary tweaks, then the long process of tearing-down and rust bluing.

i couldnt wait for the fire danger to pass before firing it.
I would fire that standing in a pool of gasoline.

its just outstanding

I'm hoping to go out at the end of this weekend to test fire this thing. Since I'm going to be probably messing around with tweaks as I test-shoot, tweak, shoot..., I went ahead and gave it a quick cold blue. I thought I'd post post a pic of it with some color on it...



@ Blurrededge - No, I haven't tried cycling any live (real) rounds through it yet. I was tempted, but I didn't want my name mentioned in the evening news if my gun fired because I was feeding it live rounds in my house... So, I hopefully will learn more about the true degree of what probably will still be a problem, but with all angles looked at. (wish me luck)

R A N G E    R E P O R T

So, I took it out today and did have some issues, but pull trigger did equal bang..

I started by loading a single round and an empty mag. Fired once.

Observations:
1) Fired OK - Finger pull was not too great.
2) Brass fell to my feet.
3) Brass showed an area of high wear on rim.
4) Firing pin penetrated deep, but did not appear to be anywhere near puncturing.

Next, I place 3 rounds in a mag, charged and fired.
1) Again, round ejected at my feet.
2) Next round failed to eject and stove-piped.



3) After clearing spent case, I pushed the next round (somewhat weakly) forward and fired
4) The third round made a weird noise and smoke was coming from receiver. This round failed to eject as well, and upon clearing I found that the shell had ruptured.



Perhaps I should not have, but I continued to fire this weapon. All subsequent rounds failed to eject - either stove piping or not even leaving the bolt. I ended-up breech loading and then placing an empty mag back in to offer some protection if another shell rupture were to occur, which it did not.





After about 30 rounds, the FCG began to fail to reset. Upon investigation, I found the take-down tang was tearing from the tube and this allowed the fron of the lower receiver to swing out slightly from the tube. In this condition, the FCG could not grab the hammer.



A closer look at the spent rounds back home revealed that there is some nasty interference between the bolt face and the rim of the rounds. I should be able to alleviate this with some gentle rounding of the sharp edge on the bolt face.




So, obviously I am a bit concerned about the ruptured shell. I have a feeling that the bolt was not fully closed when this occurred, but not 100% certain. Any input on this would be greatly appreciated.

Other than all that, it was a pleasure to shoot. Not much recoild and it just felt "good". I could imagine once I get some issues sorted-out, $200 tax that would allow me to add a folding stock may be well worth it.

EDIT - I failed to mention that the ejector is definitely too short and needs to be extended upward about 1/32".
