Known Main Lug problems, 2 on the Parker site, 3 on this site , and the 12 I mentioned on this site.
Total of 17 We know of, all in different parts of the country. Just think of how many We don't know of ?
Oh, and by the way, the picture Ted showed of a Parker with a failed lug, the gun looks like it was hardly used, or ''shot''.
Dirty Harry
Dirty Harry, are you saying you know of 17 different Parker Repros with lug joint failures? If so, can you be sure the total does not include guns that were counted two or more times? And do you have any details or evidence whatsoever about these alleged failures, including photos, 17 different serial numbers, and the circumstances leading to the failures? I ask because we saw photos of the same very few cracked Ithaca Flues frames posted and reposted so many times on this and other gun forums, that it made the alleged problem seem real. In the end, it turned out that there was hysterical rehashing and some purely anecdotal evidence. In addition, when we did get actual details of actual cracked Flues guns, the majority were subjected to severe abuse, doubling, and loads that were unsuited for a light upland gun. The big problem was an "expert" making a mountain out of a molehill.
https://www.doublegunshop.com/forums/ubbthreads.php?ubb=showflat&Number=609802&page=1So far, we've seen one photo that pretty clearly shows a poor braze joint. But zero RCA (Root Cause Analysis).
Do we have knowledge of the gauges of the failed guns? tmc
At this point, we don't even know if they were all Parker Repro guns. And we don't know if people are counting the same failures multiple times. Or any details at all. Welcome to the Internet!
Can we get a link to the threads that describe the three Repro failures on this site? I don't seem to recall reading about them.
Good point eightbore. Neither do I, except for this one that looks very familiar. You'd think the Preacher would have posted links and pictures of these alleged failed Parker repros... ad nauseam...
https://doublegunshop.com/forums/ubbthreads.php?ubb=showflat&Number=638919&page=1I don't know if anyone has sent the remains of one of these guns to Dewey Vicknair, or if he would be willing to provide an opinion, but he no doubt could explain the failure
I'm quite certain Dewey Vicknair would immediately see a poor joint due to some brazing error or fault. If he had the barrels in hand, he might even detect signs of contamination or burned flux. He could then elaborate on the possible causes. I've already listed several possible causes for such a poor joint, but I'm not making any wild-assed guesses based upon a photo. With the scant information we have now, he couldn't know if some sort of severe abuse contributed to the ultimate separation failure. He never claimed to be a metallurgist, so I don't think he'd have the means to do any spectrographic or chemical analysis.
I would like the Preacher to tell us about his personal experience with soldering, silver soldering, brazing, etc., and how he determined what particular process was used on the Damascus Parker he showed us. In my shop right now, I have several alloys of silver solder. Most are a silver/tin color, due to their composition which is presumably mostly tin with a smaller percentage of silver. Some silver solders contain significant percentages of lead or nickel too. But some have a distinct brass or copper hue, because there are many different alloys of silver solder and brazing rod. Some alloys of brazing have a silver color. The distinction between the processes lies mainly in the temperature required. In addition, we do not know that joint is original. The excess material on the barrels just ahead of the flats suggests some past repair may have been done.
BTW: another alleged cracked frame Flues

Unfortunately, Dewey totally deleted his account here due to buffoonery, and even managed to get his old posts deleted. All of the PM's we exchanged are gone too. If he saw the picture of this latest cracked frame Flues, I'd bet he'd want to know what sort of abuse led up to it finally breaking, after holding up just fine for 90 years or so. I wish he was still here to counter buffoonery from wannabe experts, but I don't see that happening any time soon.
