08-28-2012, 05:03 AM
Hello to everybody, I have an old DeVere 504 that i love, but I have a problem , I have not a perfet focusing on all the image.
And that make me crazy!
What is unbelieveble is that in the X axis, I have on focus the right side and the center, not the left side , how could that be possible?
For be shure that was not the negative, I put glasses on the neg carrier but the problem was the same.
The only way that I found for have mor or less a sharp image is turn a little bit the head on left part
but of course the image have a distortion.
I bought on ebay a manual about devere but there is no explanation about set the focusing of the Head.
Anybody have ideas, and know what can I do?

You need to align the lens and negative stages to quite a bit of accuracy.
I don't own this enlarger, but someone who does posted this method of alignment:

Here's the answer for anybody interested...first level the enlarger column by adjusting the legs of the enlarger. Then level the base board using the adjustment screws hidden under the baseboard. (Don't forget to check that the paper easel sits perfectly level on the baseboard too.) Next you must level the lens and negative stages in both the horizontal and vertical planes. To adjust the horizontal plane is easy, each stage just swings around a 'pivot screw' which you must first loosen: the negative stage pivot screw is behind the lever used to lift the head, and the lens stage pivot screw is right behind the lens. These screws are loosen by screwdriver or they may have a 'swan neck' handle on them that you can open manually. To adjust the vertical plane (the angle between the column and the stage) is a bit more tricky. First you have to locate the correct screws. Here's directions: the arms that hold each stage come in three parts, the first is called the 'runner', which is attached to the column. Then there is a middle part, and last of all the actual stages themselves. The screws you want are those that join the middle part to the runner, and you find them by looking up inside the middle part of the arm (you might have to unscrew a small metal plate to see inside the lens stage arm). On the bottom left and bottom right you'll see two big screws that stand out from the surface...these are the locking screws. Right beside them, embedded in the metal you'll find the adjusting screws. There are two steps which involve first loosening the two 'locking screws' per stage and then screwing in/out the two 'adjustment screws' per stage which are located right beside the locking screws. Of course you must lock up again when the stages are level. Remember to adjust the enlarger with the head on and the negative carrier in...'test it as you use it'!

Alberto, what Ic Racer posted is very good advice.
I would suggest you first check the baseboard first. Usually the base board has been fiddled with when the board is taken off and put back on for moving.
It does take a bit of time to align the baseboard, so take care.
With regard to the negative carrier being out of alignment, sure it can happen, but my experience is that generally these machines are so robust their neg carriers and lens holders hardly ever move.
I would suspect the base board as the main culprit.
