Whist we're talking triggers....

Gents, the recent discussions about triggers, the Huber replacements and so forth....I decided to open up my 'new' 1916 Lithgow, and try to diagnose my suspect 'one stage' trigger operation.
So I've read thru Peters very detailed explanation of the Trigger Pull Off, and after a few reads I started to understand the lingo of 'cocking bents' and 'first pull ribs' and so forth.

OK here's my question. The cocking piece, or more specifically the cocking bent of the cocking piece, has a shallow groove worn into it from many years of the engaging with the sear nose for the good old cock on close. So as part of my 'setup' do I stone (in an up and down fashion, Peter) the face of the cocking bent of the cocking piece...as part of the bolt preparation, as I cant see this detailed anywhere.

My second question relates to the trigger axis pin. Ive got a bit of 'side to side' slop in the actual trigger itself. I'm assuming worn pin, and rounded shoulders of the actual trigger. Now I'm assuming that my only course of action here is to drill for an oversize pin. In the trigger and trigger guard alike. What size pin, and where do I get one from? Once I have this major source of slop out of the trigger itself, and a smooth face (im assuming) on the cocking bent of the cocking piece, I can start to fine tune for 2 stage perfection.

Thanks in advance.

It sounds to me like the trouble you'd go to for an oversized pivot pin would be less hassle if you purchased a new trigger and pin for a couple of dollars. just my 2 cents.

I just noticed you're in Oz and that means you'll pay $5 for the parts at Numrich in the US and pay through the nose for postage, I've got spare triggers and pins here (NZ)if you want replacements.

Trigger and sear axis pins are identical to the pin, cap fore-end. Just use one of those................ You'll get two or three per pin!

Starting to get a handle on this now...even thou the trigger is a bit wobbly on it's pin, and something that i'll be looking at sorting, I've managed to get myself two stages on my trigger pull. The main issue was that the first rib of the trigger needed filing down as it was releasing the sear before the top rib came into play. I made sure the firing pin was tight in the cocking piece, I then polished the face of the cocking bent on the cocking piece, and whilst keeping the same angle worked out the groove that had formed. The sear also was polished where it needed to be, and rounded where it needs to be. So now I have a nice even first pull to a point of resistance, and a nice crisp let off. I will see if I can work out what pull weights I have, as it feels pretty good how it is now. I will investigate some fine tuning now that I think I have a very small handle on some of these techniques. Thankyou very much to Peter who's fantasic write-ups continue to help those that seek the knowlege.
