Default RE: Quick question on Solder Clevis

Well I decided once and for all to see how strong a solder clevis really is. I took a 4-40 rod 12" Twisted one end into a loop and a silver soldered clevis on the other. I ran a section of rope through the loop then tied to my work bench. I attached a T shaped servo horn to the clevis. Holding onto the with a rag and pressing my legs against the bench where the other end was tied I pushed with my legs till something failed. The pin going through the clevis snapped. The solder joint did not move at all. I do go to the gym and can leg press about 275 lbs. which is way more force than ever would be place on the plane. So with that being said a CORRECTLY done silver solder joint is strong enough to take what we throw at it
