Correct, the fixed gobo wheel and the color wheel seem to be on the same shaft but they're driven by separate motors(fixed gobo wheel is direct, color wheel is with a belt) The reason I want to remove the colour wheel is I want to glue new glass onto it.. one of the previous owners of this before me changed a bunch f the colours for whatever reason.... it has 4 different greens, 4 blues, 2 oranges..... 0 red, pink and purple... But I have a color wheel from a different moving head(Studio Due Shark 250) with all the "normal" colours, so I'm attempting to put those glass pieces into the mac 250 entour's colour wheel!. The Mac 250 Entour's colour wheel has these little plastic clips designed to be able to easily swap out/ replace colours however I guess because it's so old all of the clips are either broken or very brittle and break when you try to remove them so I figured I would just glue the glass right onto the wheel but I need full access to the colour wheel first! I tried removing the screws again on the shaft but that does not seem to release the fixed gobo wheel at all, even when I use quite a bit of force. Here's some photo's: a few photo's
