Set trigger question
« on: June 06, 2018, 07:00:34 PM »
For a double set single phase trigger.   Should you be able to cock the hammer without setting the trigger?   In the gun I have,  the trigger has to be set before you can cock the hammer back.  Is that normal or does the trigger need to be worked on?

Some careful filing in the right places will allow the trigger's kicking bar to drop down enough to clear the sear, so that you can cock the lock without having to set the trigger.  The mainspring needs to have a stop that allows the trigger to float.  But it's easier to build a triggers that has the kicking bar hard up against the sear all the time.

Trigger needs to be worked on.  The kicking bar is too high.

Thank you for the replies,  so you should be able to cock the hammer without first setting the trigger.  I'll work on it.   Now I have to figure out how to get the trigger guard off.   Drift the pins out without damaging the stock.  The pins are small and hard to see,  I'll have to be careful.

Sometimes a single release trigger's rear trigger bar can be ground off quite a bit. Just remember to
not grind the area where it locks into the front trigger.IF the lock has a fly,sometimes the trigger's
mainspring can be relaxed by backing the tension screw off so the trigger bar can bump the sear
and not really compress it.These problems are usually caused by mismatching parts and not knowing
how to read a simple ruler.I do NOT recommend bending the sear.

I agree with Bob on bending but I have ground off a LITTLE of the sear bar when I was unable to get quite enough clearance by filing off the kicker bar to allow the lock to cock.

And I have a hard time finding triggers that are TALL enough to even reach the sear...   :o

I just had the same problem and had to build up a trigger bar for a poor boy.

I don't remember ever having that problem, is it feasible to take more wood off the belly of the stock?

I'll trade you my tall one for your short one  :D

Actually it's going to be tricky to get the trigger guard off so I may have to grind it down without removing it from the stock,    I may be able to get to it with a long dremel grinder bit.

They're great for all kinds of work, like lock inletting, trigger bars and guards, etc.  ??? :o ;)

Definitely not.  Most of the triggers seem to be designed for the scrawny hockey stick guns, and not for something from the 1750's!  Sometimes they can be made to do, but sometimes it's just not gonna work very well.  A few years ago I took a Davis set trigger and I made new front and rear triggers for it, and then all my gunsmithing projects were put on the back burner....then the heat turned off... then put in Tupperware and in the refrigerator...  Now, years later, I want to get back to the rifle, and I can't find the dang triggers!  Grrrr..... >:(

I've seen where people have inlet the set triggers deeper up into the wrist of the stock so that the triggers will reach... It makes my teeth hurt... ;D

Stophel, 
       If you contact the folks at R.E. Davis they can supply DST with high bars.  I think they make them especially for some of Chambers kits...

I think it would be possible to get a grinding burr down the hole in the wood where the trigger bar is located.  going in through the lock mortise.  Then grind off the top of the trigger bar.   I would have to mark it first to know how much needs to come off.  The only other option is to try and drive the pins out that are holding the trigger guard on so that I can get the trigger out.  The existing pins look pretty small.  I'm concerned about damaging the wood around them.   Looking closely at the trigger plate I see a wood screw near the rear and the barrel tang screw near the front  but there also appears to be two round spots which may be nail heads.
