Luger Steel Lanyard 'Staple' - Page 3

G.T. · 05-03-2017, 04:10 PM

Sometimes, maybe most times, nothing is ever as it seems! Once a part like a lanyard ring is installed, it is probably never given a second thought buy the manufacture, as they come to realize, even the smallest amount of press fit, riveting, swaging or upsetting will far exceed the demands that the loop will ever be subject to? In essence, even a thousands of upset, will make the loop permanently locked in place...
I remember back in my first life as a boat motor mechanic, we had a 140 HP outboard throw a rod and it caused the flywheel to spin on the keyed taper crankshaft end?... We broke every puller we had, and then some we borrowed and the flywheel would not budge... We ended up at a Catapillar (sp.) dealership with one of the biggest pullers and a 1" impact wrench driving all home, with no apparent success... So, we just stood there and stared at the block/puller assembly on the tailgate of our shop truck. All of a sudden, BOOOOOM!!! ....

.....The flywheel and puller blew off the block and flew a considerable distance up in the air... it seemed like a few feet, but was probably just enough to clear the crank, anyway, it was off and on the ground... As I inspected the flywheel and hardened crankshaft the key was sheared like butter, and the taper on the shaft had a barely visible upset ring of maybe one to three thousands high and looked like a scratch, and this held all those tons of force!!! It was not lost on me, how much weight even a thousands can hold... It certainly can hold a couple of pounds at the end of a flexible rope?...

... best to all, til...lat'r....GT...

We need pics.

I do not think a press fit would have made the engineers happy as it would eventually have worked loose.

According to several members here that is exactly what happened.

But 'loose' does not mean 'fell off'. If the holes were indeed chamfered, the loop could still stay in even if loose.

I'm checking the blueprints now and I see nothing of an inner chamfer.

Pages 1801-2-3 of the TBLAP DVD show excellent drawings of the frame and the holes and their dimensions...but no chamfer is shown...

Rich,
that frame is long gone, it may not have even been mine.
And I may or may not have installed a loop into the holes, if I did
I would have used red loctite and been done with it!

I did not think it unusual to see the chamfer, so it never dawned on me that a picture would be of value.

I'm not trying to change your mind, and it is really akin to the question of angels dancing on the head of a pin, it really does not matter to me how they were installed!

If you are happy with a press fit- good enough for me.

I have no preference of how it was done...I just need to know if it will hold up to being pulled against!!!

If you can pry it off with a screwdriver, then I'll have to think of something else...But if it takes a hammer and punch then I'm golden!!!

Sounds like an easy enough experiment!
