latch shelf repair

[mtbugle]

well with trotterlg's coaching I finally built up the courage to weld and refile down the latch shelf on a barrel I got on forum here and later noticed that the latch shelf was filed down out of level and the angle back to barrel was flattened out a lot.  Long story short I decided to weld on the cold side thinking that penetration wasn't imparetive and was just wanting to add height. But as most with welding experience probably know I would, I ended up with voids between my beads.  I should have had the heat up so lots of melting and mixing of weld puddles. Live and learn i guess. The voids are not detrimental to engagement or even in mating area so I will not redo just for the aestetics. Fits real good and engages all across as should now. Nice way to spend an afternoon. Just need to get ejector part now as that was also broken.  Thanks Larry for the confidence boost to get it done.
Thanks Don.

There are lots of ways to solve a problem, glad you found another, post some pictures and tell us how it works.  What kind of ejector are you looking for?  Larry

How did you weld it??
Mig, tig, stick, gas?

That's good news Don, I bought a Sears fluxed-core welder(Italian made) earlier this year and have thought about using it to build up the pivot on a loose fitting barrel instead of using a shim, guess I'll just have to give it a shot. The only concern I have is the size of tips may create a challenge to getting a good weld, I've done ok on flat surfaces, this may be beyond mine or the machines capabilities, but I'm glad to see it works well on the shelf. 

thanks,

Tim

Thanks for the kind words guys. I have a hobart wire feed welder that I got a year or so ago. I have not figured how to put pictures up yet. I may have to figure that out soon.  I came across a question this weekend. Does the latch need to be a little rough to latch properly? I shot my new BC barrel and it popped open. It had plenty of latch engagement, but I didnot  have more ammo to try after wiping down to insure no oil on latch mechanism.  The reason I ask is that I used some 600 grit to smooth up shelf when I finished fitting. Not having ruled out oil, I still wondered if too smooth would it be too slippery like has oil on it? Does any one have experience on this?
Quick, with that pin filing alignment tool you built I would not be too worried about doing some welding on it. But it seems that the JB stik repair seems to work very well and is quick and easy.

Don, see How to Post Pics in the FAQs or in any classified forum. 

As for the shelf being too smooth, it does required friction to work properly, that's why any lubricant affects lock up, but whether the surface being too smooth itself I dunno, the weld is likely also harder than the shelf itself, so that could also affect how it works,  I guess you'll find out for us!!

Kinda sorta off topic but..........
 Tim,
  On my Lincoln that I use flux core wire in I removed the large screw on shield to allow better access in tight places.If you like you can buy or make a thread protector (from a gas shield)or do like I did and not worry about it .

Thanks George, I'll give it a look.
