It should be possible, if you can find tubing for the rivets. I do have some 3mm stainless tube and I'm planning an Alox Chicken that I might put a bail on if I can form the end of the tube satisfactorily.
That looks really good Syph.When you say quite solid, no chance of the bail slipping out of the screw holes? Even if the SAK is yanked on the keyring?
