Trying to remove the pin thats holding in the extractor on this Turknelli bolt. Appears to be completely captured, that is to say, has no hole on the other side of the head to drive or push it out like Benelli's have. Anyone got an idea how to remove it? Is a Charles Daly Defense/Chiappa branded job. Cheers.

Fairly blind to drill from the back side unfortunately, have considered it. Same for drilling out the pin, have no leads on a replacement. Thinking a rare earth magnet while tapping on the backside...

Spring tension on the extractor will also hold the pin. Can you put some pressure on the side of the extractor while tapping?
It looks like a solid pin to me. I'd center pin punch it, and drill, very carefully, straight through. Then successive size bits to enlarge the through hole until the pin is all but completely drilled out. Then I would collapse the pin in on itself with a small chisel or the like and drift it through from the now opened end.
Then I would size a roll pin to replace the solid one.
I took a jewelers file to the extractor to see if reshaping it will help. Not hopeful, but last shot before risking the bolt head with a drill. What if I took a drill to the extractor itself? Drilled out where the pin fits through the extractor, and right through the pin. Hopefully leave enough of a nub to pry the pin out from the inside, and grab it with pliars from outside. Or maybe lucky enough to break the extractor off after drilling and remove the pin whole. That seems less likely. Drilling a hardened pin out from the end seems likely to just create a hole too large to use after.

There is an acquaintance of mine that used a really small end mill - in a drill press - to drill out the end of a broken off HSS tap - successive passes with his x-y vice until he got break through at one of the holes along the tap - it more or less fell out at that point - maybe want to try with an end mill, instead of a twist drill bit? Something telling me it was a tungsten carbide cutter on end of that end mill - maybe from Amazon.ca?? It was really small - I do not remember if that was a 6-48 tap or 8-40 - but he did not want to mess up the tap hole, nor the threads that he had cut already - just using a "dull" tap, I guess.

It's a good idea, and maybe try it first but I believe the extractor will be a lot harder than the pin?
The extractor is for sure putting a bit of pressure on the pin but it's likely seized in place, I've never tried an ultra sonic cleaner but I wonder if it would help?
Penetrating oil would be worth a try.
Then I'd try and figure out a way of holding the extractor to take the pressure off if possible and slide the tail portion of the bolt into a long section of pipe of the a suitable inside diameter and tape it on there with some electrical tape. Now you have an "inertia puller" and can slam the bolt onto a block of hard wood and see if the inertia will dislodge the pin.
Another easy thing to try is see if it will go in a bit further by giving the pin a light tap or two to hopefully break it free and allow it to come out.

I suspect so, it is flat though so might be able to mark it with a center-punch. Also think could hold it more securely in a drill press vice than going after the pin with a drill, ie a better angle.
All good ideas. I'll maybe give the pin a blow/rap and same to the extractor near where the pin goes through, may free it up. I tried G96 to no avail (don't have access to an ultra sonic cleaner), but that was worth the shot just for the smell. Have a Seafoam or CLP product, can't remember top of my head which, that has freed quite stuck things in the past. I suspect that the hole is just so tight that its never going to come out normally. The pin that holds the firing pin in place, which when removed opens the whole bolt, was so tight that it required some serious force to remove. An out of spec pin punch did not help anything either.
I'll take it out to the private range (farm) on the weekend for another test fire, maybe will get lucky with the reshaped extractor. Win or lose its always a good day if working on firearms; I appreciate all the advice Men.
You may notice while reading this thread that everyone else is enjoying some gunsmithing problem solving. Your most welcome to participate, but if your averse to hand tools, the bashing threads are elsewhere.

id just ask the wholesaler for a new complete bolt head so you don't have to worry about replacing the exactor .
