Thanks for the detail. It sounds like I need to do one slot at a time if they need to be level. I have a 110 UV cure light for watch repair work so that should be OK. When you say not to worry about the inner slot can you explain that?
As to the double post. I wasn't getting any answers there so I decided to post it in a more populated area. My bad!
Don't worry, there's always a whole bunch of us online at any one time... So, your posts will be read. Just be patient.
Yes, installing tritium vials can be very therapeutic.
Do it a slot at a time. Anyway, the slots on the bezel are milled such that the trit vials are visible from both the outside and inside of the bezel. (See photo below). What I meant is that there's no necessity to tape up the smaller inner side window. You do not have to worry about Norland 61 leaking out.
As to whether your curing lamp works, you can always test a tiny drop of Norland. Should set pretty quickly if the wavelength cover is good. Or if you do not want to waste any Norland, you can use a bit to try to fix your trit vial position, whilst testing your lamp. Anyway, Norland 61 is pretty forgiving. So long as it is not fully set, an acetone moistened cloth cleans up most mistakes.
