The Hotech kit makes it a lot easier. There is another way to check if the primary is square to the baffle tube with a laser at the back focus, a board at the front in the primary focal plane and a point light source (like an artificial star) in the middle of the board. It's a bit involved but it can tell you if something is off. I'll try to find a link to the procedure.
