I'm having fits with this slipjoint I'm working on. It's my 5th slippie, and I wouldn't quite say I have it figured out. The previous four have turned out passable, but I'm seldom content with "OK." Problem on this one is that it won't snap shut right. I have decent snap at half and a nice click open, but can't get it to close up good. I don't have a mill. I have brass liners and .05 bronze washers, and lubed with a tiny drop of mineral oil. All parts polished to 400 grit.
Things I suspect include pivot pin too tight in the pivot hole, drag on the sides of the blade (but shouldn't the washers take care of that?), or the spring isn't strong enough (but then why the snap out?).
I could polish out the pivot pin a little. Haven't peened it yet. I could bend the spring a little more for more preload. Or I could take some off of the neck in between the pin hole and the bearing surface, but I don't know if that would make it stronger or weaker.
Any ideas?
