This post is made on the request of Ian, so he could follow the "work in progress". A few weeks ago, Ian and I met again in person at the
shootingrange after a couple of years missing out due to covid, Brexit and some
other discomforts. It sure was good to, meet again Ian! After Ian’s shooting time in the range, he told me his Baby
Automag was broken. The rib came loose at the front section. Aww… that didn’t
look good… I remembered I read a post here on the forum with a similar
problem on a 44 AMP. I searched and found it was fixed by William aka WBautomag.
What a nice work done. To make the story short(er) I told Ian I could fix his BAM
the same way. More on the fix to be followed. Here’s a picture from the broken rib. |

A quick update on the repair for the Baby Automag,
Watch how little the weld was burned-in to the barrel, just a few small bits lay on top. I made a brassplug on the lathe to protect the muzzle: ![]() Pressed the plug in and degreased the rib and barrel, then secured the rib back in place: ![]() To be continued...

Time for another update.
I made a "pocket" as William did, so the weld could get deeper into the barrel and rib. The picture dose not show the depth well, but it is 3mm deep and spread about 50/50 barrel/rib. I guess it's not need to use the millingmachine, so I used the dremeltool and a small roundball endmill. It should all dissapear nicely after the welding is done anyway... Made the cavity about 4mm wide and 3mm deep. I stayed away from the sides so the weld should just "flash over" and fill the cracks to. That should be nice hole to fill up with welding material. ![]() Well now it's time for the welding. Since the old original weld was "burned in" very little, I'm thinking of using a "big stick" to weld. The plan is to put the pistol on a big chunk of metal, weld on the chunky metal first and then quickly jump over to the muzzle and rib. While it has beeing awhile since I did some welding, I better practice a bit first. Wish me luck! |

So, I guess that wasn't the only one. At one point Brian Maynard was managing AMT's customer service department. He told me they re-welded quite a few rails back on BAM barrels.

I think a TIG weld would be more appropriate for a weld fill like that. It will be hard to control that stick in such a fine manner. If it does work that will be a feat!! Good luck!!

Thanks for the suggestion Omie01, but I don't have a TIG welding machine.
I'm still exersice but found this welding fixture online for better control of the stick... ![]() |

Didn't William clamp some aluminum bars to the rib and barrel as kind of a make shift heat sink before he welded his?

Allright, joking status is over… A man has to know his limits, and as I am no welder at all
(I can just melt metal together with a stickwelder). I took this part to a good friend of mine that is a
professional welder. He did some “micro welding” jobs for me before and I trust
him he could bring this to a very good result also. The result is fantastic! He said not to worry about the heating of the metal, he has
all sorts of welding machines and took one that heat up very local and small
area. So no need to clamp on extra heatsinks. As always, the pictures tells a thousand words: Now it's back at my turn to remove the extra material and further procedure... |

I was kind of wondering what you were up to.
I'm no welder but when I saw that welding rod I thought something was not quite right.

Hi Luc, I am loving the updates and the post a couple back put a smile on my face as that is about as good as my welding is. The last time I did any welding was in my early twenties and I remember saying "It worked well on the practice weld I did yesterday" after finishing the monstrosity of an attempt and that was the last time I did any welding, I am just lucky that camera phones where not a thing back then. Looking forward to the nest update and heading back to see the work, thanks to your friend for the micro welding it is very much apricated. Ian
