But I tried it in my ER42 with a bit of a sloppy fit to a 3/4" collet. I was able to reform it slightly while cold, but ran out of threads for the nut to advance far enough to bring the collet to anywhere near closing all the gaps between its fingers. Re-assembling it without a collet also disclosed that the mouth of the body was also in close contact with the rear of the ball mounted front wedge. And the ring was not yet small enough to fit in a 5/8" collet so a step and repeat wasn't possible.
So I took it to the jewelry store, about 15:45 where his daughter says he can look at it tomorrow. Cost wasn't mentioned. Since I can afford it one time, its a shrug anyway. > On Monday, November 18, 2019, 3:47:22 AM MST, andy pugh > <[email protected]> wrote: > > On Mon, 18 Nov 2019 at 03:52, Gene Heskett <[email protected]> wrote: > > I suggested that the jewelers usually have an expandable tapered > > arbor, and a collet of sorts that can adjust a ring, cold, by about > > a size, more if heated. > > https://www.cooksongold.com/blog/equipment-technique-focus/how-to-resi >ze-a-ring > > > But what about my ER42 kit?
