I start with oiling escape teeth, but smallest amount whilst observing the amplitude on tg, and let the movement run for a few minutes, then add a bit more & repeat, keep on as long as I gain amplitude, stop where amplitude stops increasing with more oil. Then add foxodrop. I think this will ensure no oil spread on unintended/ nonfunctional sections, but only where pin and escape teeth engage and no extra oil to avoid later gumming out . I am not sure if this approach is the best. But I think if oil is only on engaging sections it wouldn't gum unless the watch spends years in drawer. Reg -

Thanks for the reply! The problem is that the barrel arbor doesn’t stay centered inside the mainspring. When I insert it, it feels like it doesn’t catch properly, and as a result, it sits off-centre. Also, on the other side of the barrel, the arbor’s pivot doesn't protrude far enough—it should stick out long enough to engage and keep the full barrel assembly stable, but it doesn’t. You can see this clearly in the photo. Thanks for pointing out the raised section of the mainspring between 9 and 12 o’clock—I hadn’t noticed that earlier. I might be able to sort that out, but I’m not sure it’s the cause of the problem I’m facing with the arbor fitment. Appreciate any further suggestions! Thanks again, TT -
Got it off amazon, brand is Harfington. I just measured and it measured at 31.37mm diameter and 1.01mm thick. The original measured at 1.22mm thick. Maybe I should have ordered from esslinger. Gonna fix that now. -

I have the pro version from Frank (praezis). I use it with an old Vibrograf mic, and it's easily as good or better than my Witschi S1. -
In what way won't it fit? Is it the outside or the arbor hole? Spring looks raised between 9 & 12?
