Omg!
I didnt even think to use that.
I have just recently bought a big roll of Ebony star, and should have heaps left over to use for the secondary cage. Just need to paint the inside flat black.
The Formica rolls up nicely too!
I owe you one Ausastronomer!!!!!!!!
One last question: For the side bearings , I have found a pair of metal rings at work, about 23" diameter. Do you think the formica will stick to the curved steel surface well, or does the steel need to be "roughed up" first?
Where did you (Orion) source your bearings from?
