Is this a part that should be moving?

I'm in the process for shopping for a knurling tool, but they run about $ 200ish to $ 300ish on ebay.... :rolleyes:

charle.emond: I can mail you a couple of the necessary sized pins. Got lots of spares.

:cheers:

There are lathe knurling tools which are tightened to clamp onto the area being knurled, as opposed to the usual kind that are forced against the work. Maybe one of these could be used. Much less than $200-$300.
 
Sorry, there are many mysterious words used here, I am getting confused and I have no dictionary handy (I am not handy man). Can someone possibly, if it is not too much trouble post a pic of the peened barrel or how the roll pins should be done properly to stop the movement in the op rod guide?

The process of peening is shown at the begining of part 4 of the Abbetsford video. The roll pin replacement process is depicted at the end of part 4 and the beginning of part 5.

Per a post from Hungry:

"Okay here's the situation.... I often replace the stupid cheesy roll pins that the Kommunists use to secure the op rod guide on the Norinco barrel. I employ a 1/8" diam x 3/4" long roll pin that slides in and out of the existing factory hole (that used to employ a metric pin).

Then I would flare open that pin while it's halfway INTO the op rod guide (hole), FLARE it wider/open with a very specialized 'flaring' tool that only the M14 clinic attendees from the SW Ontario (EESA hosted) session will know

After it's opened up a bit, I will drive in a 1/16" diam x 1/2" long roll pin INTO the 1/8" diameter roll pin. This combination will solve the loose oprod guide problematic to many of the Norinco M14."
