just looking at the bottom ring with regard to removal to get powder coated.
That also has the input plug for the fan - was it a hassle disconnecting it - from memory, you have modified that to use another 12volt supply is that right?
So to remove the bottom ring, if you looseen the 3 collimation knobs, remove the spings and then take off the bottom ring using the 6 screws, what happens to the mirror - is it being held on by anything else or does it just drop down - being really, really careful.
when changing the collimation knobs when I first got it, the instructions were always "make sure you change the knobs one at a time, one at a time. . . ."
Cheers
Martin
