wheel building woes.
Re: wheel building woes.
Have you or have you not flipped all three wheels in the dropouts and observed where the rims sit?

If my tensioning was crap would the rim move with tyre fitting and leaning on it etc. Didn't think it was loose, squeezed spokes but no tension meter used. Plenty of care, or so i thought, checking tension by feeel and sound
It could go out of true if the spokes are very slack and not bedded,etc,but it'd be very unusual to go out of dish 4mm all the way around.
Following the advise given of turn the wheel around in the drop outs should reveal whether it's dish or frame at fault.Redishing the wheel to suit the frame shouldn't take long to do.

Re: wheel building woes.
Since the other wheels line up no problem and are centred, I suspect the wheel is not seating in the rear dropouts properly. Is the length over locknuts (OLN) the same for this hub as the others? Does it fit into the frame snuggly or it is loose? OLN is either 130mm or 135mm - same as distance between the rear dropouts. But also check that the end of both axle ends are seating in the rear dropouts properly. If the OLN is 135 and not 130 then you are having to splay very slightly the stays to get it to fit, in which case it might not be seating in the dropouts properly. Although it should work if fitted with a bit of care.

Thats the only explanation I came up with.
If the new (normally-dished) wheel doesn't work, and random other (normally dished) wheels do work, then the new one can't be fitted square.
If the axle was bent, then the rim position in the dropout would vary with axle rotation.
There are a few hubs designed with an eccentric to tension singlespeed drivetrains with vertical dropout frames, I don't know what can go wrong with these.....

Re: wheel building woes.
it does seem that the wheel is either sitting badly in the frame or badly in the wheel building jig somehow....?

Can you post a picture of both axle ends? (without the wheel in the dropouts) A couple of shots so we can see what the ends look like from different angles. [edit] And a shot of the dropouts, too.
Re: wheel building woes.
Well, i backed everything up and started again. Moved the rim over a few mm and all is fine. No idea what was up except possiblly some years ago i may have changed bearings and used something wider thus moving the spacers. Anyway it works. Rim is well used anyway so within a mm laterally and radially will do.ta for help.
