Set triggers

Ok.....the set triggers work great with lock out....and with it in....they are a 6lb pull on both set and unset.....I keep filing a few strokes, then try.....and it 'feels' like there's a clearance between the bar and trigger.....but....still 6lb pulls.....do I need to filing???......

And yup, read the trackofthewolf instructions......I'm just wondering.....any ideas?

Your saying that with the rear trigger unset, cocking the lock to full cock is no problem and the front trigger needs about 6 pounds of pull to release the lock?

And your saying, with the rear trigger set so it "clicks" into place without moving forward at all, the front trigger still needs a 6 pound pull to release the lock?

That would be a confusing situation but notice, in the second paragraph I said, "without moving forward at all".

My guess would be you are pulling the rear trigger back to set it but the front trigger is not catching it and holding it in the "cocked" position.

If this is happening, when you release the rear trigger thinking it is "set", it is just moving back to the unset position where it started.

That would make the front trigger the only thing that is releasing the sear, just as it does when you don' first set the rear trigger.

Typically, a reason for the front trigger to fail to "catch" and hold the rear trigger in the "set" position is, the little screw between the triggers is screwed in too far.

Try backing it out some or better yet, completely remove that little screw. Then try setting the rear trigger paying particular attention to whether it remains back or if it is still moving forward when you relax the pressure on it.

If it is still moving forward without the little screw in the trigger plate, remove the trigger assembly and find out why.

If you've filed the trigger blades so the lock can be set to half cock and full cock without any trouble, while the rear trigger is in the unset position, don't do any more filing.

Zone,
With the hammer down, small screw removed, rear trigger is loose, front trigger has 1/4" free travel before I feel it touch the searbar.
I can set the rear trigger, pretty hard pull....the front hair trigger has still has 1/4" play before engaging and a 1/32" creep...then a 1lb pull to release the rear trigger.
With the lock removed...no other changes...the rear trigger clicks in with a 2lb pull, front trigger will travel 1/4" and release with a small amount of pressure..6oz?
With lock still removed....and the small screw mostly in....we get easy set, and 1/32" travel before it goes off...that screw is the "overtravel screw"?
When I put the lock in....I can feel the sear bar touch in the triggers I believe....so it seems my triggers are really weighted by the sear bar the whole time and need more file....?
Seems they are trying to lift the sear while engaging each other???....cause the whole thing works great w/o the lock assembly in....I need to mention....tip cutis showed me years back, the "proper" sear travel...VERY minimal..this lock sear bar travel is a good 1/4".....maybe....I think more trigger metal removal....
I'm off to the salt mines....but when I can, I will log in and see your thoughts...and remember, this Lexington is very thin wrested..so everything is tighter than my other builds we have talked about...

Long live single triggers......errruugghhh these set triggers!!!!

My best guess. It sounds like you may have too much sear engagement on your triggers. The front trigger should not have to move 1/4 " to be set. Look at the sear on the front trigger, the rear surface of the sear should be just above the trigger pivot or very slightly toward the front of the plate. The rear trigger bar should just nudge the front trigger to engage the sear. If it has to push the front trigger as far as you say, the bar may be too long.

The rear trigger 'sets' the front hair trigger, they work great with out the lock in....and seem 'loaded' when the lock is in place....but NOT using the 'set', just by itself, the front trigger will release the hammer with about 5lb....

ok......I think...I just need to file more off the rear trigger bar....does it sound like it's trying to push up on the sear when I'm setting the hair trigger???

I think I will put a 1/8" spacer between the trigger plate and stock...then see how they work....instead of fileing more off......
if they work, then I know we need to file the tops more.............

tomtom knows the problem....I just cant understand his mutterings..........

How far does the front trigger bar rise when you pull the rear trigger? Could be the front trigger bar is contacting the lock sear as the rear trigger is pushing it to set. It would have to overcome the force of the lock sear spring in addition to the trigger sear spring. As I said in my previous post, the front trigger shouldn't have to move much in order to set.

Just a thought, but it might not be your triggers. There might be something hanging up the sear bar. without the triggers in push a screw driver up and push on the sear bar or see if you can look into the guts from the trigger plate side and see if its still touching wood. or put some inletting black on the tip of the bar and install the lock.

Or...

You might have a deep full cock notch. The spring on the rear trigger kicks it up and "smacks" the bar causing it to release regardless of the full cock notch. but your front trigger has to push the sear bar until the sear comes out of the notch, equaling heavy trigger pull.

Without looking at it, there could be several things going on and not your triggers.

Good luck!! Please report back what you discover!

thought about that today....I thought I had looked at the clearance on the sear bar of the lock......i'll look again, I just get going to fast in making the whole rifle...I need to focus on the triggers....nothing else tonight!!! :hmm:

thanks fellows!!!!!!
i'll report......

Ok fellas......I made sure the sear had no binding.
Then, I adjusted the mainspring screw, making the set trigger give more power to the upward motion, and also adjusted the backlash screw to give the set(rear) trigger have more ummph.
Now it worked perfect!!! :surrender: :bow:
I DO know that the sear will slightly touch the rear trigger unset....but I have such a deep notches in the tumbler....the hammer is safe.....no amount of pushing makes it fall.

Basically, I could file the rear trigger more, so it doesn't ever touch, unset or set....but it would increase the distance before striking the sear.....and when the front trigger is used without setting....I get a small helping push to offset the sears return spring....so, it ain't broke....I'm not gonna fix it!
Dang set triggers.......have to be a rocket scientist to install them :youcrazy: :surrender:

I'm sure Tomtom knew what the problem was and what you needed to do to fix it but he enjoys watching your frustration so he keeps the answers to himself.

Cats are like that.

Yeah....they're like...."I'm gonna watch you mess with this for 3hrs"......then, I'll come over and lay on the parts.....

Now I need to tweet the pb latch...spring is to heavy...

And more wood removal from around the lock areas..... :youcrazy:
