Hi Ian, I'm glad I didn't scared you with my welding picture!

Now for the next step, I tought at first to chuck the barrel in the lathe and turned the muzzle down again. However I had to put on the 4 jaw chuck and reset center etc. that I tought it was not worth the trouble.
I went for the old scool tactic and used the file...
I have used this (yellow) set of diamond files many times and they cut through anything fast.



Here's what the welder grinded off and were I can start:


So far it seems to be working well:


A little later and some rough sanding:


Still some bit to go and some final cleaning up and polishing to do later...

Here’s the final polishing and cleaning up.

After the rough sanding I used finer and finer grid sandpaper and gave it a good cleaning with some chrome cleaner. This works to remove the hot streakes on the exhaust of my motorcycles so I might as well try it to remove the welding discoloration. It worked extremely well. No need for additional work. Some small spots of darker collour, but after a couple of shooting and cleaning sessions it will be all gone.

The pictures: with one remark, it is very difficult to make a good picture on a shiny object, so the dark streakes you see in the last picture is the reflection of the rubbertile the pistol is laying on:




So, awhile ago Ian asked here if this forum is still of any use? Now I’m glad he did saved it and made it up-to-date! It is thanks to a previous post made by wbautomag (William) that I offerd Ian this help. I would never thought it was possible to do this kind of welding, I would have gone for silver (hard) soldering of the rib. (even tough I still think it would be a stronger option as I should solder ALL the ribposts instead of welding 3 spots) On a side note, with todays induction heaters soldering makes much less mess as back in the day with flame torches.

All-in all it is also thanks to your forum Ian, that your BAM is repaired that way and good to go.

I guess the following is suitable to close this adventure,

one happy dancin’ baby….

Yeah, I've only done crude arc welding in my much younger days too, when I was an apprentice tin-smith, which I abandoned to pursue eng studies, but I digress.
Mig and Tig welding was always something I wanted to learn more about, just because, but never did, as I got into the more academic realm. But I'd still like to learn them, just to further my practical knowledge even if I don't do it professionally. Being able to use it to fix hobby stuff like this is a perfect example of why.

That's a nicely done job Luc, by both your friend the welder and yourself for the grinding and polishing job.  The polishing and finishing touches is where the quality of the fix shines through.  I'm sure Ian is glad you were able to do this for him. 
BTW, Ian,  That BAM is damaged goods now, it's had to be fixed, so I'd say it's devalued severely.  How about I make you an offer on it and take it off your hands real cheap?  LOL.
Seriously though, congrats on the BAM rib rescue project. Always great to see the good folks on this forum come together to solve something.  And that's why I'm glad you keep this forum going, as Luc was mentioning.
I don't get on this forum often enough these days, but I'm glad I decided to check it tonight and read this thread.  Great stuff.

Cheers.
