Obviously, you have no concept of manufacturing.
Nearly ever company that I have worked for has been a manufacturer. I've worked assembly lines, I've overseen assembly lines, I've done production line repair, I've done consumer repair, I've done test equipment calibration, I've been responsible for maintaining ISO standards within an engineering and product development lab, I developed manufacturing processes, I've done UL safety testing, I've worked in product development where I troubleshot new designs and corrected engineering mistakes, I've made numerous design changes to existing products, and I've designed new products. I've worked for companies whose quality control was Deming based.
I'm aware if nearly every kind of problem that can occur in a factory. There are very few problems that are not preventable with good process control and production worthy designs. I have seen insanely stupid things done in companies that are often pennywise and dollar foolish. I know where companies try to skimp on materials and labor.
As for your spring. Whats the tensile strength? What's it made of? Do you even know?
Dude, you are NOT paying attention. I posted this at the beginning of the discussion:
"Spring Pin, Coiled, Stainless Steel, 420, 3/32 in Outside Dia., 1/2 in Fastener Length, Double Shear Strength 1,150 lb - PK 50 $7.51"
Did you note the double shear strength of 1,150 lbs? Did you note that I specified 420 alloy stainless steel? Or perhaps you just aren't familiar enough with metal alloys to recognize 420 as a stainless steel alloy.
They use a machine to install them into the gun. I have never heard of one falling out.
None the less the coiled spring pin in my P365 was NOT correctly installed and it was mangled. My installation using a brass faced hammer, a 1/8" pin punch, and the butt end of the drill bit did NOT mangle the coiled spring pin and it was inserted to the correct depth. SIG has a production process problem. I do not.
That spring was designed for that gun by someone smarted than you.
Sez who? FYI, my IQ scores have averaged about 135. Most companies that I have worked for seem to think I'm smart and they have said so in written performance reviews.
You're an armchair gunsmith that really has no idea what you are doing or changing.
Sez who? You? Have you noted the testing that I've done on my P365?
That spring will fail at the worst possible time.
SIG did not design that coiled spring pin. There are only a few different companies making them and in total, for that size pin, there are 3 strengths made from carbon steel and 3 strengths made from 420 alloy stainless steel. I chose the strongest and more expensive stainless steel alloy pin. It's being used in a very non-demanding situation as a pivot. It could possibly wear out, but not likely before the extractor claw breaks from a stress fatigue failure. The chance that this pin could ever actually break in this application is nil to zero. The fact that I use perhaps the best synthetic grease to lubricate the pin and I will likely replace the pin at least once a year makes it highly unlikely that I will ever have a worn out pin.
As for using a drill bit to punch out a pin, that's just stupid.
A drill bit It actually works pretty well for occasional use. In fact, my results using a drill bit have been completely successful in installing the coiled spring pin to the correct depth WITHOUT mangling the pin. Whereas SIG screwed up and mangled the crap out of the pin and was UNsuccessful at inserting the pin to the correct depth. Are you really trying to argue with success?
You're using a hardened piece of steel, you're going to wallow out that hole.
Dude, a pin punch is a hardened piece of steel. As long as you size the punch correctly and use it correctly the punch does not even touch the side of the hole.
Chances are you wont because you sound cheap.
So that is why I use one of the most expensive synthetic lubes on the market?
I have a better idea than you do about about assembling and fixing guns.
You have already indicated that you did NOT understand process control. You accepted a FAILURE to properly insert a pin as acceptable. Sig's method FAILED, my method worked CORRECTLY.
I now have a great reason not to buy a Kimber.
