FW3A mod thread. Post yours!

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

Hi, who is selling the glow rings?

I think you can get them from Neal (Here), CRX (Here), or anywhere else that sells glow gaskets for 20mm Carlco triples.

Alternatively you could make one yourself using these instructions: DIY Glow Gaskets for Triples and Other Glow Stuff

Beautifully crafted response :slight_smile: thx

You are welcome!

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.

Neodymium magnets are brittle, so they may not last a lifetime when mounted so exposed.

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.

Just try to avoid hard impacts.

I’d do my best obviously. I wish I could make a button like yours. I’m still thinking on it a bit.

I thought I might epoxy coat it to add durability.

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. :smiley: If you glued 2 credit cards together, they still could bend though.

:+1:

That looks really cool! I may do something like that. Love your lights.





I reflashed FW3A, add a blue aux led, now it’s beautiful

Did you replace the cut + lead…

well, of course, i dont want it to be a “hot rod”

So it turns out my diffusers work great at lighting up an area of the basement during a power outage due to severe weather.

Hope you made it through the bad weather OK. Your diffusers work great even when the power is not out… I love em’!!! :beer:
