Fitting an L&R lock to a Renegade

(1/3) > >>

Eric Krewson:
I am building a random parts TC Renegade and decided to use a L&R replacement lock instead of trying to find a TC lock.

I was hoping for an easy swap but this is not the case, this lock is not a drop in, not even close. There are a lot of problems I will have to fix to get this barrel, lock, stock combination together.

Here are a few;

The lock bolster and fence are hitting the hooked breech tang and won't let the lock settle into place. You can see the shiny spot where the lock is hitting.



The touch hole alignment is way off;



The underlug for the wedge pin dead centers the opening preventing insertion of the wedge pin.



The barrel has to go down and back to make everything line up, I will start reinletting the barrel and tang today.

Eric Krewson:
Here is a little update, I have actually just about finished this project, just have a few bugs to work out.

This picture shows how far off the L&R lock bolt hole is off from the TC as well as how much I had to grind off the tang to get the lock in the mortise and have it go to full cock.



There are a lot of gaps between the "drop in lock" and the mortise.



Wood shavings to the rescue;



Pretty good fill in, the patch will disappear once the finish is on the wood.



I did a mock-up and most everything works, I had to remove a little more metal from the tang to get the lock to full cock. One more problem to solve; the lock will fire with the triggers set but not with the front trigger alone. Everything looks OK, nothing rubbing, I will solve this problem tomorrow.

Eric Krewson:
I did a trigger lock mock-up and the back trigger would set and let the front trigger set off the lock but the front trigger wouldn't trip the lock by itself. Lots of soot black and looking for pinch points came up with nothing binding.

I came to the conclusion that the L&R lock sear was a bit higher than the original TC sear and the front trigger was making contact but not enough to set off the lock. I needed to add some metal to the trigger bar.

I took the trigger apart, cut a piece to solder on, hardened it and used plumbers low temp silver solder to attach it to the trigger bar.

I started with this;



I found the front trigger would fire but now the back trigger wouldn't set. I realized my trigger bar was too tall now so I would grind a little off, test the function, grind a little off and test again. When I got down to here everything worked just like it was supposed to.

Stoker:
Very interesting Eric.. I saw those at track and was thinking about my TC hawken flinter.. Nice rifle just lock time is slow
Thanks Leroy

Josh B:
That's a handsome looking lock from what I can see of it.  I'm looking forward to the finished pics to see the whole thing. Josh
