The stainless steel used for the iz-109 is much thicker than the iz132. Close to double.

Naturally it was hard to cut and file. Went through a few cutting wheels and the little filing took a lot longer. Heres the result:

PG, trigger guard, and stock installed

I used socket cap screws to install the trigguer guard. Instead of having two more nuts in the receiver I just taped the receiver for the two front holes. 6-32

Mods of the hammer and retaining plate. Lots of grinding to get them to fit. Had to grind the leg to get the BHO lever to fit and had to grind below the face of the hammer so its fits the S-12

FCG installed

close up of the folding stock's latch. Ended up using a spring from a nice pen. Not a clickie pen but a nice ink pen. Didnt even know it had a spring in it. Very stiff so it worked great after hacking at it a little.

Notice the bolt hold open tab is filed so its flush with the receiver when its engaged

Whats a receiver stub? I used the pic thats floating around that has all the measurements. Just masking taped up the end and drew out the measurements.

Some times when you buy the folding stock with trunnion hardware its still attached to the cut receiver stub. Good build

No, You did NOT crush the trunnion rivets with a chinese C clamp..........did you?????

 

I'm going to be doing the same thing soon. I'm been looking for another latch, I'd prefer to buy one, but at least I can see that one can be made.

 

Very good build, congratulations

The folder did come off a hacked receiver stub. So had to de-rivet the stock trunnion and the trunnion that came with the folder. Not too fun.

 

Yeah used a cheap hacked up c-clamp, same one I used for my iz-132.

 

I was going to buy a latch but even a 2nd hand one was $70. Took a few days but I already had the aluminum so cost will close to nil :)

 

The square hole & pin hole are the same size & dimensions as stock. Just made the latch go far enough back so you dont have to hack the stock to fit. I followed a lot of sKott's conversion and saw that was one of the problems.

 

edit:

what solvent do people use to get the lead out of the barrel? After putting some sluggers through there was a decent amount of build up. After a few hours of cleaning there is still some left. I dont have any solvents though so just a brass brush and some rags. Has to be an easier way... Any suggestions?

Awesome job there, James! Great writeup and is a tribute to those of us who are brave enough to do our own conversions. Wish I could do that style conversion here in NY! Congrats and have fun with it. I like the full stock on it.

The electric drill that Cobra suggest's work's well. But if you don't want to do that, get a tornado brush (google it) it work's great with your favorite solvent/cleaner or whatever. Great job!!
