I received a fine looking and fully functional Vivitar VI Dioptic enlarger from a nice gentleman.

Before putting this into my darkroom, I would like to align it. I have a Versalab Parallel laser alignment tool that my girlfriend bought me.

Problem is, I can't figure out if this enlarger is able to be fully aligned. I looked at the user-manual and looked closely at the equipment itself. I can see the film stage can be moved by losening 4 bolts. The lens stage tilts side ways only. I can't find any way other than shimming to align the head relative to the baseboard.

I can see I can do the parallelism alignment between film stage and the lens stage. Seems there is no way to do baseboard vs head alignment.

Does anyone know otherwise?

Also, does anyone know if focusing knob can be made tighter?
