Slipjoint Fit Up Using a Kennedy Fixture

This is a demo on how I use the Kennedy Fixture from Jantz Supply to fit up a slipjoint blade and spring. The Kennedy Fixture is an advanced version of the Ruple jig, or a rise fall indicator.

Nice video. What I do with my bushing is scratch a mark on it at 6 o'clock. Then I made a part to hold the bushing in place as I rotate the blade. I took some round stock and drilled a hole in it for the pin, and tapered the end so it sits on the bushing. With this I can hold down the bushing into place as the blade is rotated on the jig. This really helps keep things consistent.

That's a great tip! I would love to see a picture of it, as I'm having trouble imagining it. Would you mind contacting me through my website so I can talk to you more about it? I'm doubting you would want to post your email address here. :) chriscrawfordknives.com/contact/ Thanks!

Thanks for the very usefull info.....this info makes it all a lot easyer for those that are starting in making slipjoints. Few questions : do you use the same steel for the spring and for the knife??? And if you do , doesnt that cause galling up the contact points when opening an closing the slipjoint?? How hard do you make the springs (hrc)??

[@chriscrawford5392]

Hello. Yes, I do use the same steel for the blade and spring, but they're heat treated differently. As long as I have the contact surfaces smooth and a bit of oil the knife, I've not had a problem with the pieces galling. It will be a problem if you have sharp corners on the tang. I've not hardness tested my springs in a while, but from what I recall, I shoot for around 49rc give or take. Hope this helps.
