You may remember the MDF round I cut last weekend. Today I made two more cuts. First about 2.5″ inside to give me an 18″ OD ring that I will cut in half to make the altitude bearings of the scope and another to make the cell that will hold the mirror. In hindsight the cell doesn’t need to be as precise as the bearings and cutting it with a jigsaw would have been way easier. Also in hindsight I used MDF because I had it lying around and it was a test cut that turned out well but plywood is easier on the router. The ring on the right will be tossed.
