I've Got An Emergency!
« on: September 27, 2008, 04:02:56 PM »
I was shooting today and the extractor to my Romanian M69 trainer crumbled. It looks like there was an air bubble when it was cast. No excessive strain, so I'm a bit confused as to what happened.

I need a new one. Does anyone have a source? This is smack in the middle of squirrel season, not to mention rabbit season's coming up and I also need to shoot for points.

I'm not confident in my abilities to manufacture a new one.

Help!

Thanks,

Josh <><

Alert canceled; I was able to fabricate one out of an old wrench.

Thanks folks,

Now just how the hay did you manage to do that???  When you say - 'out of an old wrench' I am imagining an extractor large enough to yank an artillery shell out.  Mikey.

Hello,

It's nothing fancy.

Just used a flat piece of steel.  I used an old wrench because it's tool steel.

A hand grinder makes the process easier, but keep in mind that all the fine work is done with small files.  You will need a drill to make the hole, but that's it.

Start by taking the old part out.  The pin (at least on mine) drifts up from the bottom, out through the top.

Cut an "L" shaped piece of metal of approximate size.  A hand grinder with a cutting wheel attachment comes in handy for this.

If you've ever had one of these out, you'll see that there's a "tail" that the spring rests against.  A hand grinder with a fine grinding stone attached makes one of these nicely.

I found that holding the new piece in the bolt and smacking it through the hole with a punch gave me a better location for the pin than did the old piece.

It's very important that you fashion the hook by hand.  Those grinders can get away from you.


Notice the circled part.

That relief is very important to feeding.


Play with the height of the claw as well as its reach across the bolt face.

The hook should just hold a shell on.  Remove the extractor, take a couple file swipes, then try again.  I can't stress enough the importance of a sharp hook; it's critical to ejection in these.  If you work slowly and get the hook and tension just right, you'll have nice, strong ejection compared to the usual weak ejection of the original extractor setup.


Side view.

It's also very important to get the side recessed into its groove.  If you don't, it will hang up on the receiver wall when you have a shell in it.

Altogether, plan on spending 6-8 hours on this project.  It looks easy, and it is for the most part, but the final fitting really takes a lot of time.

Thanks,

Josh <><
