SKS to FAL conversion, MK1 (56k warning)

maybe the dirty reds back in the day thought "that H Wally guy is going to make a FAL out of our sks one day.. the motherland wont accept that !!.. make the hammer rediculous so it wont work! " ..
thats my version of events anyway

Hmm. You know, I suspect that it was a conspiracy between the czechs and the russians, after all, they're so close to each other...

Assist the hammer with a harder spring?

That is the other solution. First off, I don't know how to take apart the FAL trigger spring assembly. If I could figure that one out, there is the possibility of the trigger spring being strong enough to fire the bullet, but then be so strong that it would stop the bolt cycling.

I think I shall try to get a stronger spring assembly made...

Wally,

I'm trying to figure out the moment of force applied on the hammer of your design compared to that of the original FN. How close to the axis or rotation of the hammer does your hammer spring connect? I can't make it out from your photos.

From what I understand of the question - I'm using an FAL lower, so everything but the Hammer is original. The hammer has had the top 1 - 1.25 cms removed from it. The trigger spring connects to the hammer in a notch about 1 cm or so above the axis of rotation when it is in fired position. It would be possible to raise it provided I could build the weld up carefully enough, and that there was enough room for compression in the spring assembly for it to compress that much further.

I think I see what your thinking.

Hammer is set too far back, not enough force left in the spring, hammer is lighter so it should be moving faster, but not enough momentum when it strikes
 
I would have done all your MIG and SMAW welding for free, would of turned out a tad bit better :p
And penetration would of been ideal.........Looking like the penetration is so so -

If the pieces you join next time are thick try to bevel them then fill them up / grind them down!

Overall great job, I am over in surrey if you need any help!

Alright guys - a little news.

It functions fine with commercial ammo, so at least we know what the problem is.

Now I need to find a way to make a stronger hammer...

Also, if anyone out there is in vancouver or victoria and has machining/ design skills I need some help making a new safety sear. I've got a good idea how to do it, just none of the machinery.

P.S. - if anyone has FAL lower parts, I'm about half the pieces short on the last reciever. I can probably make most of them, I just don't have much time any more.

whats a disruptor ? you mean like a safety sear?
 
H'ok, slow and steady movement forwards.

Tested it some more this weekend - 40 rds of primed commercial brass all functioned flawlessly... only thing is that the primer indentations are rediculously light.

Also worked on it internally... I've got the safety sear, disruptor, whatever the heck it's called fitted and almost functional. Since I don't know for sure what to call it, it's a little safety arm similar to what can be found on the front of the SKS trigger assy that stops the gun from firing out of battery.

Also welded and fitted the dust cover.

After this, I need to make a mag release and it's functional! Aesthetically, it will need the welds cleaned on the mag well, rewelding, sanding, primering and painting.

PICS!
