Chain Games 3: Tightness - good or bad?
I've had occasion to replace or re-use pins in various chains of late, and one side effect seems ubiquitous: the repaired link is way tight, as in binding. So how to get it loosened up? I've tried working them, using penetrating oil, and prying. The latter seems to work best but that's not saying much.
Btw, I also found that seating the new pin fully helps quite a bit.
If I don't get this figured out right, I will have to go get tight and get into someone tight in something tight.

Call me The Breeze
Try bending the chain with your hands back and forth against the links (sideways) at the offending spot. Not sure if that's a good explanation or not but that's what I've got.

Worth keeping in mind, though.

No one has had to loosen up a tight link?

Hey thanks! I hadn't seen that page.
The uniqueness of the "loosening shelf" on the Park chain tools is a little obscure. It seems to be that the shelf is free-standing, with no "anvil" behind the chain to brace it. When pressing the rivet, the teeth of the shelf force the links apart. I can do that with my (not Park) tool by backing off the screw-in anvil.

I haven't needed to use the loosening shelf on my cheapo tool yet. (knock on...)
Apparently you don't push too hard?

I use my chain tool.
It has two positions. I put the chain into the chain tool so that the back plate is supported by the chain tool and drive in the rivet until the front endof the rivets matches the rest of the pins in the chain. Then I relocate the chain on my chain tool so that the back plate is unsupported drive the rivet an additional 1/4 turn. Works every time.
