Swivel keyring

[DaveH]

Part 3 the final part.

The “end cap,” the part on the left hand side.


Faced and then drilled a 6.1mm dia (in my case) hole. I drilled it about 15mm deep.


Check to make sure the swivel will go in.


I turned down the end of the 14mm dia brass to 10mm dia by about 4 mm long.
Chamfering the previously 6.1mm dia drilled hole.


Checked to make sure the body will go on.


At this stage you can part it off, or just hacksaw it off, put it back in the lathe to clean up the face. Use a little emery in the hole to get rid of any burrs.


Now we have all 3 parts, time to see if they all fit.


No not quite – see a small gap


I reduced the length of the swivel, (faced it off in the lathe) use some brass shim so the part isn’t damaged
There we go fits!


I used loctite to fix the parts together. The nut allows me to hold the parts together in the vice without touching the swivel. Now you have to be a little careful with the Loctite just use a small amount around the step on the “end cap”
Check to make sure the swivel swivels. If the swivel accidentally gets stuck, well that just means you have a swivel key ring without the swivel – still good as a key ring.


After the loctite has cured can be put back in the lathe (don’t forget the brass shim) to shape the end.
The top slide / compound slide is set over at about 45 deg. Being careful not to stuff up the swivel.
This is after a few cuts


After the final cut.


Clean up with some fine emery cloth


There it is


I tend to use wet & dry paper to get a nice finish. Started with 400 finished with 1000.


Finished on a buffing wheel.





That’s it folks.

Not a single micrometer was hurt or even used in the making of this swivel keyring

Hope you enjoyed it
