Cocking piece pin tilted in bolt

[Robinhood]

I remember seeing the big chamfer on the small end. I made a couple with a threaded blind hole and ground about a 1/16th of the firing pin so that I had a full length hole to remedy that. I had forgotten about that.


ChetC, Please make room in you PM's

i cleared my pm's ok now

The pin itself is made from 8620 leaded and is case hardened to R15N 90 min, .006-.010" case depth. If you don't recognize those numbers it's because it's a scale just for case hardening. It's the equivalent of 56 Rc. I'd just use O-1 drill rod.

I'm pretty sure I have some O-1 or W-1 in 1/2" around the shop. Hopefully I'll have time tomorrow to take the bolt apart and look more carefully at and measure the parts.

I checked the parts today. The cocking pin measured .211" diameter [specs are .213-.216] so it's small. The hole in the cocking piece measured between .219 and .220 with pin gages, so about .219+ with the spec being .217", so that's oversized. I made a new cocking pin that was .218 diameter. I need to harden and temper it yet. I think the bolt cocks a little easier with the new pin. It's certainly no longer cocked / angled back in the bolt any more.

Removed the big chamfer. Deleted the through hole. Reamed the cocking pin hole to 5.5 mm(.2165).

Robinhood, the hole in my cocking piece didn't have the degree of chamfer that yours had. Savage must have made improvements along the way. The G prefix in my serial number indicates that mine was made some time between 2001 and 2009. There was however an unnecessarily large chamfer on the end of the cocking pin. The major mismatch were the dimensions of the pin and the cocking piece hole. Both were at the extremes and perhaps were outside Savage's expected tolerances. The diagram of your cocking piece pretty much matches the dimensions of mine.

With the shiny one, there is about .002" clearance with the cocking pin and the though hole was omitted with a blind threaded hole in it's place, therefore the bearing surface it greater. The pin tilt is virtually non existent. The Major OD is closer tolerance so there is less slop with the sleeve. All in all it was an improvement.
