Making slipjoints is a challenge and brings a lot of satisfaction when it all comes together.
Hammering the pivot pin was hit or miss for me, being ham fisted it was not uncommon to get that blade to tight and then deal with the drama that comes with that.
I decided to invest in the time and money to start using pivot bushings ala Tony Bose.
The end result was a real pleasure when hammering and hiding the pivot. Doing the pivot can give you anxiety because you know one hit to many or to hard and you just increased your time in that knife to get it where it needs to be.
With the pivot bushing installed and with a 4 oz hammer working the pivot was easier then any other I have done. Peening the pin you can check side play and work the pin until side play is gone and the blade will move nicely with no pinching and long break in time.
It can be a bit fiddly during the build process insuring the bushing does not rotate and state in the same orientation, but that fiddly part is well worth having the pivot just work after peening.
Here are a few tools used for the bushing set up.
A barrel lap, a pivot lap, aluminum bronze bushing, grinding compound and i use a Rupple Jig to find where on the bushing the low spot is and mark that on the bushing.
The end result
