A quick little walk-through of making the finial.
I've made them in many configurations, slotted for screw drivers, made to fit matching pins in an additional take-down wrench to name a few.
But if one was to not have the exact tool to fit the finial, one wold be in trouble - wouldn't one?
So I came up with one that would utilize an everyday tool - the allen wrench.
I turn a 416 rod and machine in a shoulder that catches the ledge in the finial insert, thus pulling everything together.
Then I drill and tap a hole in the exterior butt end to receive a stainless 10-32 socket head cap screw. I'm going to silver braze the screw into the butt, and this requires an absolutely CLEAN! surface. So I sandblast both the screw and the finial.
Then, silver braze them together with 56% silver rod.
Looks a little messy at first (until I turn it again)
Here you can see the silver braze. On the first couple I did, I wondered how strong the braze job would be. I was told that the braze joint was STRONGER than the host materials? Really. I guess so. I locked one of my test screws in a vise and tried to turn the screw out. I even had to use a small pipe on the allen wrench and I twisted off the wrench! I broke it off.
Good enough for me.
