What's the trick to getting this little pin through?

I just don't have enough hands. I'm trying to link two chains and I want to save one of the special easy links. I actually did this before but my technique sucks so I need some tricks

If you are trying to re-use that pin that has been pushed all the way out, good luck. The normal practice is to leave the pin protruding on the outside link, then use your chain tool drive pin to pick up that little pin and drive it home in as close to a straight line as you can.

Easier to lay the chain on it's side and tap with a hammer to get it started in the sideplate. Looks like a 7 sp or less chain you have which is OK to do this but if 9 sp or greater you'll need the special pin or a quicklink to keep it together.

A guy in my volunteer shop managed to do it but I didn't watch. Keep at it and good luck. The tweezers are a good idea. Maybe try wiring the chain to the tool or vise to help hold it in place, and clamp it in the best you can with the threaded pin catcher.

Sorry to tell you, the trick is to not push the pin all the way out when disassembling.

If you have the old chain…it might be easier to just take the next link off…and leave the pin retained as mentioned above…and then add links from the old chain.

Thanks. I discovered what you're all telling me about keeping the pin in from YouTube. I tried a couple different creative ways to no avail and just loosened up another pin instead. I have two new chains so plenty of links. I just wanted to figure out "the trick". Got it

The “trick” is to use a quick link. Problem solved. And you shouldn’t be pushing the pin part way out and reusing it if the chain is 9 speed or above. The chain is likely to fail.
