The brass finial thing in the chuck has a threaded hole on its left-hand end, which screws (upright) onto something on the local church altar.
The tapered portion to the right is shoved into the drilled cork which is in the plastic sleeve (18” long or so). This in turn holds some sort of oil lamp.
As you can imagine, it’s not very stable. My plan is to clock the brass piece in as best I can, with no particular straight or round surface to refer to. Then turn a cylindrical portion on the tapered bit for an M10 thread, then make a threaded delrin bung to replace the cork.
I stood it upright in the mill vice and did a centre as best I could in the right-hand end.
Any better suggestions? I’d prefer to make a bung with a matching taper, but don’t have a boring bar small enough, and the taper is irregular anyway.
