Paramilitary maintenance and adjustment - couple of doubts
Posted: Sun Oct 04, 2009 12:28 pm
Just got for a fair price a used Para, standard model, PE S30V, black G10 handles. Generally in good shape, both the blade and the handles, there were some small issues with the knife:
1. Quite a bit of vertical play;
2. The clip was tarnished;
3. The lanyard tube seems loose;
4. One of the clip screws is stuck, and damaged from trying to undo it;
5. Some patina on the hidden parts of the blade.
Now, #4 is not a problem, since I did not need to disassemble the clip to run it through some ScotchBrite and solve issue #2.
#5 is a also non-issue.
#3 will be dealt with soon, probably with a drop of superglue and a subtle hammering with a screwdriver. For now, I just wrapped a bit of paracord through the lanyard tube, and tied it, to make sure the thing doesn't come apart in use.
#1 was minimized by a full disassembly and wash of the parts, and putting them back toguether rotating the stop pin to a different position. The lock travel was going nearly to the opposite handle, now it's a little better. An overall adjustment of the screws also seemed to help. But, although the knife is perfectly usable, and reliability seems not at risk, I keep wondering if there's anything more that can be done to improve the lock. By looking at it, I get the impression that if the stop pin was a fraction of a milimiter wider, the vertical play would be solved, as the lock travel would be restored to full authority. Eventually, the cause of the problem may have resided either with blade ramp wearing, or stop pin being beaten to a smaller dimension... (inertia opening, anyone? Those not guilty throw the first stone...). On the other hand, I'm under the impression that the other pin that the Para has, the back one, is an identical piece. Since this one has never been subjected to lateral stresses, and in that respect is to be considered as new, perhaps just swapping the pins might do the trick.
Can anyone confirm that they are indeed similar and interchangeable?
Another question: this Para, like my SE one, has a type of rude jimping on the spine, and none on the choil. On the other hand, both my D2 and my black-bladed Paras have finer jimping on both sides. Is this a production timeline characteristic?
