Warping the Feed on a Double Automag, Part 2:
After the filing, very careful use of some air sanders and fine-grade sandpaper
smooth things down to the point where it can be hand-sanded.
More tedium in the form of hand wet-sanding with various grits of wet/dry sandpaper.
I wet-sand to both keep the dust down (you shouldn't breathe stainless steel dust)
and it makes the paper last longer as it doesn't clog.
It usually takes at least two full sheets to finish a single body,
each torn into small strips of about 1" x 3".
A quick preliminary pass through the buffer to see how the finish is progressing,
and it's now time to... do it all over again on the
other body. :)
With the bodies finally fully sanded and mostly polished, we now locate and redrill the feed ports.
Make sure both are well deburred, and it's back to the welding table.
For this mod, I made myself a quick fixture to help hold the feed necks in place.
A bar slides in from the barrel end, and a stem bolts on and indexes into the first rod. The feed neck
slides over the stem and the whole thing is held together with a bit of allthread, a washer and a nut.
With everything in place and our measurements double-checked, each one is carefully TIG welded in place.
A short seam as shown is more than strong enough- trying to weld all the way around is
unnecessary, and would wind up warping the body again.
A quick trip through the polisher cleans up the oxidation.
Now, with the modified feeds, standard twist-lock barrels will no longer work in these bodies,
so the customer ordered two of my
AutoMag Barrel Adapters, which in this case
had to be specially fitted to the 90-degree-feed bodies.
And done! Polished up and ready to wreak some havoc! :)
