Slipjoint bushing question

As a first step in learning how to make slip joints, I decided to modify my little Fällkniven LTC by adding my own covers.
I'm planning to make micarta covers and to use a bushing on the joint pin. I don't know the correct terminology but I was hoping for some guidance on what to use for this bushing and how deep the bushing is seated in the cover. I don't have access to a lathe so I was hoping to be able to buy something that was close to what I needed.

Any input would be greatly appreciated.
 
Thank you Sean Yaw Sean Yaw , that seems like a great resource, but I was referring to something a little different. I'm talking about the bushing that is inserted in the cover or scale which the pin then is peened into.

That is not a bushing it is called a shadow pattern or birds eye pattern.
You need at least a good drill press to do them
 
Gotcha. In non-slipjoints I've heard that called the pivot collar. In slipjoint I've heard it called a bird's eye pivot. Birdvis knives has a video on YouTube of putting some in and Adam Vigil's IG account shows it pretty often.

Thanks again, Sir.
 
It is just a washer of metal. Peen the pin into a reamed tapered hole and file/sand the assembly flush with the scales.
 
To answer what material to use, use the same as the pin/pivot stock if you want it to disappear. If you want some contrast, use something like nickel or brass with a stainless pin.
 
Also, I just saw you don't have a lathe. You don't need one.
Drill your pivot pin hole where you need it to be on your covers. Clamp the cover to your drill press table with the pivot hole still centered on your spindle. While the pivot hole is centered on the spindle, you can counterbore to the diameter of your washer's stock with a flat bottom bit (or you can use a piloted counterbore and not have to worry about keeping things centered).
Next, square cut a small length of round stock for your washer, and glue it into your counterbored pocket. Carefully grind any excess round stock flush to your cover. Now you can simple turn the cover over (to the bottom/inside side) and you'll have your original pivot hole to use as a centering guide to drill a center hole through your washer material. Make sense?
Use sharp bits and a good glue and you should be fine.
 
I did a shadow pattern with a Birdseye recently. You can take a look, it is between the BBQ and some other knives
