Tight Focusing Rails on Zone VI 4x5 Wista Version
I have recently bought a Zone VI 4x5 that was made by Wista. The camera is basically a Wista 45dx with a Zone VI branding on it. The only problem with the camera is that the focusing sticky/jumpy and tight after the first inch or so. It looks like a previous owner waxed the rails. I scraped the wax off hoping it would free up some room in the rails, but it has made the focusing slightly worse. I was wondering what my options are for getting the camera to focus smoothly.
Thank you!

Before sending the camera off for a repair it probably doesn’t need, make sure the pinon gears are engaging the racks in the same place on both sides. Rack the front all the way out until its disengages, the re-engage it carefully to make sure both sides contact the pinons simultaneously.

Ditto on what Keith wrote. My Nagaoka did the same thing when I got it and doing that fixed it.
Re: Tight Focusing Rails on Zone VI 4x5 Wista Version
I concur. The focusing has likely jumped a tooth on one side. The Wista DX is not very hard to work on in this respect, so give it a try yourself before sending it in for an expensive repair. There's really not much complicated in the focusing mechanism: a rack-and-pinion gear system and a wooden bed that slides inside another. Finding the problem shouldn't be too hard if you're even a little bit mechanically inclined.
Best,

Thanks Keith,
When you say disengage, do you mean have the rail come off of the camera completely? There is a stopper there which makes sure the rail doesn't fall off so I would have to remove that first. Is there a way to tell that this is the problem before taking the camera apart?

He is correct remove the screw.
The problem is the rear cross piece. You should see rub marks where it needed to be sanded down.
