Re: Paterson grain focuser?
It is often best to stop the lens down some in aperture so you don't blind yourself.
Re: Paterson grain focuser?
Part of the practice of using these devices is to find a part of your projected image where there is a meeting of shadow and highlight areas. It's much easier to focus if you are looking at an area where there is detail, as in tree branches against the sky. If you just look at an area of a broad tone like a sky, or deep shadow, you'll have trouble.

I use 3 different Focusers, and still it is tough for my bad eyes
I use all 3, then...
Eureka never

Mark's dead-on. First you have to have a negative in the enlarger, and you need to look at a spot where there is density. The edge of something is perfect -- even the edge of the negative frame will work. It also helps if you are using a high grain film. In addition, make sure the mirror is in the center of the image -- the light has to be aligned.
Re: Paterson grain focuser?
I have used a different one in the past and the grain immediately popped out, super easy?? When I put it over what I think is a dense area still just white light.
Re: Paterson grain focuser?
Have you checked the mirror to make sure it is set correctly? If you are reading a dark area, it should be dark. Do you visually focus the image on the baseboard first?
Re: Paterson grain focuser?
Yes I pre focus then try the focuser, I wouldn’t know what to look for with the mirror setup

I assume you rack focus the image while looking through the magnifier. Even slightly out of focus grain might not appear at that magnification. It will pop into focus as you slowly move the lens. It shouldn't matter where in the image you are looking, there is grain throughout.

If your focuser looks like this, there is a mirror at the top of the column at a 45° angle held in by glue.

Is it there?
