So far we've seen the results of the incorrect application of screwdriver, hammer, punch and grinder.
Here is an example of just one way to misuse a drill. Apparently the extractor guide pins broke and drilling holes (multiple) on the barrel flats to knock them out seemed like a good idea.
Notice the rough, original finish of the barrel flats. This finish must be maintained and this area is a perfect example of the difference between "nice" and "correct" that often arises in restoration work.
If this were a custom job, the barrel flats and hidden areas would be filed and polished in the same manner as the other exterior surfaces.
The holes are TIG welded.
Of course I also made and installed new guide pins for each extractor segment to complete the repair.
