Its just a normal £10 jobby that spins on a motor under the apron methinks. Mufcmufc would be able to let us know more as I think he still has one?
I Imagine @@mufcmufc installed it though yes.
@I TiltAlot has it now, it looks great. I had a brief look at it, it is a very small projector and there is a hole cut into the apron near the balldrain where it projects from. He might be able to shed some light on it! I Imagine @mufcmufc installed it though yes.
