Thanks for the tip. I’ll post pics if I decide to do this. Will probably swap the emitters on my FW3A as well so I wouldn’t be hijacking this thread… lol
I tried a UCL 22.61mm x 1.90mm lens on my FW3A, and was disappointed to find that it created a slight gap between the bezel and the rest of the head. With the original lens, the fit is so good that the head appears as one piece.
Maybe I’ll try the sapphire lens that Neal sells or TK’s method of polishing the coating off of the original.
To expand on this idea, for anyone that wants a magnetic tail cap, I am considering using one of these to do the same. They are basically neodymium washers. My only apprehension is the 2mm thickness, but I don’t think it will be that bad.
EDIT: Also I found a pull force calculator for ring magnets and these should hold about 4 pounds which should be sufficient for the FW3A.
I had considered that. I was hopeful since they are at the lower end of the scale for neodymium magnets for magnetism that they would be strong enough.
The thickness of the magnet should be fine for breakage if backed by a solid setting bond, I would probably use JB weld instead of the E6800 as that remains slightly flexible once cured?
Plus the JB weld can be moulded up the sides of the magnet and shaped with acetone before fully cured.
Chipping shouldn’t be too much of a concern but yeah a coating might help.
I have a similar setup with a small ring magnet around the tail switch on this light with no problems. Stuck on with JB weld & surrounded with a glow mix.
The E6800 , when used in thin films is not flexible . It is when used in thicker applications.
This is hard to explain. In thin films is can be flexed but when gluing down a rigid washer with a thin film it will not move. Figure that one out. If you glued 2 credit cards together, they still could bend though.
