set trigger issue

[oldarmy]

I have the set trigger inletted. If I set the rear trigger first,then pull the front.The lock
works perfect.
However, can't seem to get the lock to fire when I just pull the front trigger.
Here are a few pics of th lock area with the set trigger installed.
Don't mind the bent set screw, that will be replaced.
Do, I just need to inlett the trigger alittle more?

There are two types of set triggers. There are the ones like you have where you have to set the rear trigger before the front/main trigger will work. There are also "Hunter" set triggers where the front will work either way. Unfortunately they are both built differently and can't be changed.

So your set trigger is working just like it is supposed to.

Sorry for the question ... but are you sure that your trigger is a double-set one? Can you post a pic of the trigger (in particular the front one)?

 

[MikeChapin]

There are two flavors of double set triggers - single lever and double lever. In a double lever trigger the front trigger will have a bar that will come up when the front trigger is pulled. This bar will engage the sear just like a single plain trigger. The single lever wil not have the bar for the front trigger. All it will have is enough metal to engage the rear trigger when it is set.

If it is a single lever, it is operating as it should. If it is a double lever you are probably right in needing to inlet it a little deeper.

With the front trigger set, you don't need to pull it back too far to release the rear trigger. But if it's not set, you generally need to pull the front trigger back further than if it's set. Make sure the front trigger bar isn't running into a bit of wood. Try taking the lock out and watch as you pull the trigger to make sure you can see the front trigger bar traveling up through the hole for the sear bar in the lock panel. If the trigger sear is indeed not coming up high enough to hit the sear bar, go ahead and inlet the trigger a bit deeper. From the photos, it looks like the front of the trigger is already inlet fairly deep, try just inletting the rear deeper. This will bring the back of the front trigger bar up higher.
Hope this helps!

Can you post a picture of the top of the trigger out of the stock for us? That way we can tell you what you have and answer your question.

sure,
Here it is. It should fire from the front trigger.
I am going to inlet the back alittle more and see if that works.
Tried to be really carefull about lining up the set screw with the sear.
If not then it's a "single set trigger rifle"
Will just have to build another one :grin:

It should work....IF....your sear arm is at the apex of the angle between the two triggers. Did you make this set yourself? Looks real good.

Sorry, Trigger appears to be mounted too far back. Try marking the top of the blade with felt tip pen ink, then firing the lock to mark the ink by the touching the sear extension. Then look to see if the other blade will reach that high. Wonky

The front trigger may be making contact with wood when it's tripped, however, the front usually takes more force to trip the sear than the back trigger.

Apply lipstick or lay out dye on the top of the front triger bar. Assemble the triggers into the stock and use the front trigger to fire the lock. Where does the transfer color show up?

Another suggestion...

1. Remove the trigger, leave the lock installed.

2. Put the hammer at full cock and mark the height of the bottom of the sear bar above the bottom of the sear bar hole inlet, i.e., you are marking a) the location of the sear bar, and b) the height your trigger bars will have to rise to trip the sear.

3. Remove the lock and install the triggers snug in the inlet.

4. Set and trip the triggers in all phases to get an idea of how high each trigger bar is rising when tripped.

This should tell you if you have to move the triggers forward, back or up.

The problem is the trigger is just.... :cursing:
a little too far back.
Just going to leave it as it is. It wasn't ment to be a hunting rifle anyway.
Now it's a single set :hmm:
Thanks for the help :thumbsup:

 

[oldarmy]

on second thought,
I will figure out how to fix it.

I think Gixmo Wonky is right on. He apparently posted his response as I was preparing mine.

Old40Rod had good suggestions too.

IMHO, it would be a good idea to follow thier advice.

 

[oldarmy]

Here's my solution.
soldered a small 1/8 piece of pin stock on it.
Filed alittle and now it trips the lock, both from a set and a non-set possition.
Have a pic, sorry it's a little blurry.
Thanks for all the help.

Defiantly a double set, looks like a Davis to me, should trip the lock set or unset. When installing this style of trigger you get only a small window of placement, up and down, to and fro. You don’t get a lot of say in the pull weight in the unset mode.

On the bright side, with that said, the difference between full function and not could be a very small amount placement. The problem is seeing inside the stock, I like to use candle black. It will show where metal touches metal and where metal touches wood. Black the triggers and the sear then put it all back together, careful not to rub any of the black off either while putting it together.

Now, cock the lock to full cock and with the frizzen closed squeeze the front trigger just to where it stops not all that hard. If it trips the lock recock and set the rear trigger and squeeze the front trigger again. Take it all back apart and inspect the metal parts for missing black and the wood for black smudges.

If you find black on the wood you need to remove wood where touched. If you look at the top of the trigger bars you should find a small spot where the black rubbed off where it contacts the sear arm and maybe wood. If your lock works in either mode you will now know where you stand. If the set trigger bar is hitting right but, the front trigger bar is not contacting the sear or wood, you need to go deeper (or up with your triggers).

By the way never touch off a set trigger while the lock is in half cock. I will brake the sear arm.

I like the trigger bar to contact the sear bar about 3/16” behind the trigger pivot point. The problem with most set triggers is it has to be a little more than that to work in set mode. So, you want the sear bar to contact the second trigger bar just in front of the notch.

Try this and let us know what you find.

Aha! Yankee ingenuity triumphs again!

Works now :grin: :thumbsup:
This what I love about assembling longrifles.
You learn great "Problem solving Skills"
Course, the problem was caused by me in the first place. :hmm:
