[/QUOTE="Originally posted by XP001.  Brian always wanted to keep the secret of how the ribs are attached for some reason. I always wanted to know the details about that, where are the welds applied and what are the issue doing it.

So where are the welds? Does every manufacturer do it this way? Has the process has been greatly improved?"
 
 
Brian Maynard told me how he attached the ribs but I didn't think it was a secret.  Brian said he drilled a hole through the rib, through the stanchion and into the barrel.  He then threaded the length of the hole and screwed in an Allen screw, (similar to part #33 Trigger Adjustment Screw) to hold everything together.  The hole in the rib was then welded in, was machined flush with the rib and Bob's your uncle.
 
The factory had the rib electron-beam-welded but they often skipped the inspection of the welds because of the cost and delay in production.  I believe it was a magna-flux inspection.
 
I know of one way the front of the rib was  attached.  A hole was drilled into the muzzle.  Half of the hole cuts into the stanchion and the other half of the hole cuts into the barrel.  The hole is then welded up to join the front of the rib to the barrel. 
 
I'm sure there are other ways it was done.

Maynard has had trouble with the rib coming loose in the front like that barrel also.  

I have seen 2 up for sale on GunBroker that were cracked at the muzzle and I have a friend that had to have his rewelded also.

On one of my Maynard barrels you can see where the screw heads were welded over on the top of the rib like Bruce describes.

I do not know how well this will show up but you can see the "shadow" of 3 screw heads.

Those are threaded into the barrel?? They must have had amazing control to bore and thread those holes into the barrel without going all the way into the bore; there's not that much meat there...

As far as I know the barrel and rib on the front has always been just welded across the front they couldn't  beam weld through the site and the rib on the barrel Bob is showing has screws in the stand offs of the rib only the extension is just plug welded.

Here's the latest on this 357 barrel, take a close look at the Auto Mag labeling before I removed it, notice anything strange ....?
So I have removed the lable & I'll be sending this to William & have him turn it into a 4.5" barrel with
him info on it.
