Poor focus

[Kilgallb]

I am not talking about movements or tilt or swing, just how do you set focus on the ground glass.

I am at wits end. The last twenty or thirty sheets on my Toyo 45CF are not well focused. I thought I was not locking down focus and movements well enough or maybe things shift when I put the film pack in place. I carry a check now to make sure things are locked.

I even went to my optometrist, I have better than 20/20 vision with my glasses.

Last weekend all ten shots were really out of focus.

So how do I check that the ground glass is the same plane as a film pack?

All Toyo cameras, except for the 45AX, come with the fresnel lens installed in this configuration: Focusing Screen > Fresnel > Lens.
Check this first.

Can you please show some examples? I'd like to understand a little better how severe the problem exactly is and perhaps see if there's a pattern to it.
Of course, also follow up on @B.S.Kumar's suggestion.
