  1. This is stellar! Thank you for the simple and inexpensive ($2.50 at my HD) solution. I'm building a new lower and, like David Craven said, this'll save me searching for the spring and detent. The only way I seem to be able to find these after they ricochet off stuff on the shelf next to me, is when I'm vacuuming the shop a week later and hear the distinct sound of something bigger than a staple rattling up the vacuum hose on it's way to oblivion. In which case, I'll still never find them.

  2. why do i see some videos with the flat part of the detent inserted over the spring and others that have the curved part of the detent inserted against the spring – does it matter?

  3. Simple and cheap! I just bought an "OOPS" kit for my missing(lost) detent. And i just launched it across the room. I'm going to Home Depot! Buying a $2 clevis pin instead of the $10 specialty tool they have out there. Thanks man

  4. Cool. I'm going to HD tomorrow. I just want to replace mine with one that is a different color and has a logo on it. Can I do that without wanting have the pin and spring pop out when taking the current one out? ..can i just reverse order and after using pick to twist and move current one , do it by push it out with that initial tool you can get at home depot? Pushing it out while detent pin is held in place and push it back with new pivot pin ? 😕

    P.s. so I got a clevis pin… and it was a bit warped so it would not fit through on that other side… so I just tried using the 1/4 " punch in reverse order because I just wanted to replace mine. I used the pick to push in detent and twist the pin, pushed punched through other side in an attempt to keep pin in place while pulling out old one pin..did not work. Lol the detent shot across half the room… but I just put detent pin back in hole where detent pring is…pushed it in with side of new pin, and twisted it into place… the only tool you really need is the pick.

  5. 10 cent trick faster easier
    EASER CHEAPER. Use a bobby pin, cut the nub off the end and slip the bobby pin behind the pin. Then slip your new Pin in behind the bobby pin. Easier if you use another Pin on the other side so the spring won't put pressure on the bobbypin

  6. If you're replacing a pin, you can use your old one (or a spare front pivot pin), inserted reverse, to hold the detent in the hole, in the same way you use the rotated clevis pin. I watched this video, but didn't have a clevis pin on hand. I used a 3/32 punch to push the detent into its hole with the spring, then inserted the extra pivot pin in reverse, as he did with the clevis pin. worked well with what I had on hand. thanks for this video!

  7. This video is bull shit because it really only shows installation which a full monkey could do. 99% of all pivot pins are soild on the opposite of where the indent is. This a phony that couldnt hit a bull in the ass next to him.

  8. Great. I’ll just run up and BUY a clevis pin…. you took something very simple and just made it ridiculously complicated. There are a dozen other ways to do this in two seconds without needing a clevis pin my friend…KNOWING nobody has one of those laying around…

  9. Thanks a bunch man, dealing with these used to be such a PITA, what a difference your approach makes!! BTW: For those who don't have a pick handy when removing the takedown pin, just grab a small thin nail and blunt the tip a bit with a file or even give it a light tap with a hammer, works perfectly too.
