I built two of Grahame Marsh's scope clocks using a wooden base, as shown here: https://www.dropbox.com/sh/rldue6seyzty9ju/AAB8kECNtxuRSKLGU4rF6Pm3a/Photos/MikeM?dl=0&subfolder_nav_tracking=1 A simple acylic case fits over the base. I used black felt to line the wooden supports. I didn't need to clamp the neck in place, the weight of the 5" tube is sufficient. The interior of the case gets to just over 80 degrees Fahrenheit during operation. The only vents are under the black box on the base.
