Anyone take apart the U2 head? How difficult is it?

Has anyone taken apart the U2 head? Especially the very front. I'd like to clean off the inside of the lens and take a can of compressed air and blow off the little bit of dust I see on the reflector. I imagine you have to heat it up pretty good....

Hi there

I took the U2 head apart with little trouble.
I secured the head in a vise with leather straps to protect the finish.
I heated the head slowly and gently but quite hot, with a hot-air blower (others have used a blowdryer- maybe a USL would work!)- this is the scary part as I am not sure if the HAIII could be hurt by this-mine clearly was fine!
This step is to loosen the Lok-Tite or similar that SF use.
Then I twisted the bezel off using a pair of multigrips with leather lining.
The whole thing took about 2 minutes.
Others have published this with photos- I guess you have tried a search!?
Good luck- I love my U2: imagine one with X-bin!!!!!!
