Lyman rebuild
« on: January 10, 2013, 07:05:09 PM »
I'm customizing aGPR I reworked the lock and smoothed out the trigger today but the trigger adj. is all the way down and it,s still about 7-8lbs pull so I nèd a longer adj. screw I guess ,I had read some where that someone sells these I'd like to have an unset trigger of about 3 lbs.
 I've got a kicking piece of tiger striped maple I'm I inletting for it also I have plans for a cast on nosecap eventually maybe metal refinishing but it's actually in pristine shape that way but so was the stock.... Maybe a capbox  not sure there either.
  I am considering some light carving and / or wire inlay  have n't yet ventured there yet but nothing ventured nothin gained,right? Any suggestions or hints? Any thing else  with the lock or trigger if you've worked on the Lyman's I'd like to hear from you.
I go forth armed and girded as a free man.

That screw adjusts how hard it is to set the rear set trigger. It won't lighten up the front trigger unset.

Yes,... you need a longer "set adjustment" screw, and one with metric threads.
I used to find such screws for my GPRs, in old tape players and CB radios.

You might also be able to match the screw you now have with a longer length, at your local hardware store.

Beaverman may see this and have something of value to offer.
I think he did a couple not all that long ago.
There used to be a "sticky" here which covered one of his GPR' rebuilds.
Which, I can't seem to find. :oops:

You know,I don't know how many times I've read it,and I don't know how many times or how many guys told me that, BUT,finally after reading a post by Cannon,it sunk in and I retread all the posts and realized that the adjustment screw only adjusts the SET PULL,(did you guys know that?)LOL sorry,It's my thick German skull genes!
 My lock 's SET PULL is good and I have smoothed everything out so it's a fairly Nice lock,what I want is to lighten up the UNSET pull and correct me if I'm wrong but I think someone also mentioned that the coil spring is the target here,I can probably figure it out but is there a disassembly tutorial here for this lock? I would like to reduce it to at least 3-4lbs unset ,another question is ,if I lighten the unset pull via shortening the coil spring will this lighten the pull at the trigger adjustment ,it seems to me that they kind of work independently of one another to a point(TO A POINT,) sorry I will try to listen better.smile!

I dunno, I don't think I would cut any coils off the minspring.  I would polish the innards of the lock - the sear, the tumbler, etc.
Take the lock out of the stock and mount it in a vice.  Bring the hammer back to full cock.  Take a flat tip screwdriver and capture the end of the spring.
Lift up on the sear and let the hammer down.  The plunger and the spring will now come free.  Warning:::::  The plunger and spring might make a dash for freedom at that point, don't do this in a cluttered shop, as finding the errant pieces might be a bit difficult.
Live simply. Love generously. Care deeply. Speak kindly. Leave the rest Up to God.

I  like a set trigger ,especially for range work and if I'm on stand but not when I'm still hunting when those quick shots come up I like about a 3lb trigger I rework all my rifles triggers to this weight my T/C was actually no problem ,set was about 1 1/2 lbs and 3 1/2 unset ,none of my muzzleloaders had this much discrepancy between set and unset,but this is an unused rifle and was never worked on before and I like that part.

That's a cool tool set up there Bigsmoke and I will polish up the innards before any nipping occurs .I did polish the sear arm and trigger bars already and this smoothed it up quite  a bit but I have not gone into the guts  except to polish the point of the sear and the frizzen and frizzen spring just enough to smooth them up.

It only takes a "split second" to set the front trigger,.... I've never had it EVER present a problem for me while hunting.

Most of my guns have set triggers and I love them.  I use them at the range and in the woods.  I don't wear gloves while hunting so a light pull works just fine.  All my set triggers are set about the same; two that I've measured were 13oz set.  The rest feel about the same.

I pull the rear trigger when I enter the woods, so all I gotta do is cock the piece and slap the front trigger when I have a shot at game. No problems after many years.
